v2.6 October 2026

New: Your Social Security claim age now changes your benefit. Enter the monthly amount you would get at full retirement age (67) in today's dollars, pick any claim age from 62 to 70, and the plan applies the early reduction or the delay credit for you: about 30% less at 62 and 24% more at 70. The benefit keeps up with inflation, both before you claim and every year after. The same works for CPP in Canada, from 60 to 70
New: Survivor planning for couples works in both directions. When either partner's plan ends, the survivor keeps the larger Social Security benefit, files as single from then on, and pays tax and Medicare for one person. The main projection, Monte Carlo and the stress tests all follow the same rule
New: Partner Retire Age now drives the plan: your partner's contributions continue until the age they retire, then stop
New: Spousal Social Security follows the official rules more closely: the top-up goes to whichever partner has the smaller benefit, it is based on the other partner's full retirement age amount, and it is reduced when it starts early. Survivor benefits include the 82.5% floor
New: Guides and answers to common early retirement questions now sit at the bottom of the page, with links to the full FAQ, glossary and blog
New: The demo shows a clear Sample plan badge, and nothing you try there is saved over your own plan
Improved: Monte Carlo now uses one market each year for your whole portfolio, the way real markets move. Stock market accounts swing about 16% a year whether or not you set a stock and bond mix, and other holdings follow a smooth scale, so two plans that are almost the same get almost the same score. The middle outcome lines up with your main projection. Success rates may read a little different from before, and they are steadier
Improved: Monte Carlo charts and percentiles count every run, including the runs that ran short, so the fan chart shows the full picture. Monte Carlo also covers exactly the same years as your main projection
Improved: The stress tests replay history on the stock side of your accounts, while bonds earn your Bonds return, and cash and Social Security keep pace with the inflation of that period. The historical returns now include dividends and were rebuilt from S&P 500 total returns and CPI data. When a scenario's recorded years run out, your own plan settings carry on
Improved: Monte Carlo and the stress tests treat money as arriving and leaving through the year, the same way the month by month projection does
Improved: Locked money stays locked in every projection. Roth earnings wait for 59½ while your Roth contributions stay available at any age, an HSA opens at 65 for medical costs, ISAs and TFSAs are always open, and each partner's accounts follow that partner's own age
Improved: A SEPP/72(t) plan opens its yearly payment before 59½ and nothing more, and the Rule of 55 opens workplace plans (401k, 403b, 457) when you retire at 55 or later, matching the real rules
Improved: A one-time expense larger than your accessible money is now paid from retirement accounts once they are open, with the tax included. If nothing is open yet it shows up as a shortfall, so big expenses are never skipped. Monte Carlo and the stress tests handle it the same way
Improved: Flat Rate tax mode: capital gains fill the 0% band first and then use your Capital Gains rate, the band follows your filing status, and Traditional withdrawals count toward how much of your Social Security is taxed
Improved: Every field is read the same way by the main projection, Monte Carlo and the stress tests. A blank or out of range box falls back to the same safe value everywhere, so the three results always describe the same plan
Improved: Coast FIRE, Bridge Years, Withdraw Rate, After-Tax and Smart Insights all read from your projection, so every card and tip shows the same figures
Improved: Dividends and price growth now add up to exactly the return you entered
Improved: 2026 figures refreshed: the $7,500 IRA limit, the $242 Medicare Part B and Part D base premium, and updated reference notes for the UK, Canada, Australia and India
Improved: Outside the US the calculator uses the Flat Rate tax method, since the bracket tables are US federal brackets
Improved: The Social Security break-even chart and the delay tip use the same claim age math as your projection
Improved: Tools menu calculators handle zero and blank entries, show clearer results, and the 72(t), SIPP, Super, RRIF and EPF tools use current rules
Improved: The yearly table shows your real contributions in working years and marks the rows where an account runs out
Improved: Easier to use with a keyboard or screen reader: every control can be reached and has a name, focus is always visible, text contrast is stronger in both themes, and tap targets are larger on phones
Improved: Phone layout: the header wraps cleanly, chart controls stay readable, and the Age column stays in view while you scroll the yearly table
Improved: The page settles faster. Your theme and Simple or Advanced mode are applied before anything is drawn, and Portfolio Mix no longer jumps into place
Improved: Clear All Data explains exactly what is removed and what is kept, and the button wakes up once you type DELETE
Improved: Link previews and search engines read the page title and description right at the top of the page
Improved: The success rate reads 100% only when every single run made it
Improved: Light theme: switches that are off and the edges of fields are easier to see
Improved: Every dialog returns you to where you were when it closes, and the Notes panel stays out of the way of the keyboard when it is closed
Improved: The Social Security break-even chart is shown in today's dollars, and the report and Income Floor chart show your benefit at the claim age you picked
Fixed: An age typed out of range, such as a retirement age below your current age, no longer freezes the page
Fixed: The Income Streams switch stays off after a reload when you turn it off
Fixed: Your claim ages are kept when you switch region or reload the page
Fixed: Your own Social Security and pension end at your own plan end age when your partner's plan runs longer
Fixed: Social Security tax thresholds follow your filing status in every projection
Fixed: Monte Carlo and the stress tests count the part of the year after an account unlocks, so a plan that the main projection funds up to 59½ gets the same credit there
Fixed: The status box always names the age when money runs short, and a plan that never runs short is no longer marked as failed
Fixed: Today's $ view works when inflation is set to 0
Fixed: Cancelling Add Account no longer leaves an empty $0 account behind
Fixed: Clear All Data in a region other than the US starts you in that region's currency
Fixed: Copy buttons work in browsers that block clipboard access, and saved files are named with your local date
Fixed: Advisor white label: your firm name appears in the page header, and Hide BridgeToFI Logo hides the BridgeToFI name as intended
Fixed: A plan whose money lasts exactly to your Plan Until Age is no longer flagged as running short
Fixed: Monte Carlo and the stress tests no longer count dividends on cash
Fixed: Sorting your accounts refreshes the projection right away
Fixed: Add Account closes the type list properly before the details open
Fixed: A share link that cannot be read shows a clear message and leaves your saved plan alone
Fixed: Opening an advisor link never replaces the plan saved in your browser
Fixed: A pension lump sum that arrives in the same year as a large one-time expense is counted before the expense is paid
Fixed: Large amounts in currencies such as the rupee are no longer cut off at dollar-sized limits when you switch region
Fixed: With the Rule of 55 switched on and no workplace plan to open, the status box now reports a bridge that runs short

v2.5 October 2026

New: Stock / bond mix for each account. Open any account and pick 100/0, 80/20, 60/40, 40/60, 30/70, or type your own split. The account earns a blend of your Market and Bonds returns, Monte Carlo uses swings that fit the mix, and it works together with the Pessimistic, Moderate and Optimistic buttons
New: Portfolio Mix shows your overall stock / bond split (for example 64/36) right next to the blended return
New: Roth Conversion Ladder: choose where the conversion tax comes from. Pay it out of the conversion, or pay it from bridge money so the full amount lands in the Roth. Modeled in the main projection, Monte Carlo and the stress tests. If bridge money cannot cover the bill in a given year, the rest comes out of that year's conversion and the calculator tells you when
New: Flexible Spending has a Spending Floor: the least you could live on each month, in today's dollars. Your spending is never cut below it. Leave it blank to use 75% of your Monthly Spending
New: Flexible Spending shows what your percentages mean in dollars: the first-year amount plus the leanest and richest years of your projection
New: Shared links are safe to open when you already have a plan saved. The shared plan opens for viewing, your own plan stays untouched, and the bar at the bottom lets you keep the shared plan or go back to yours
Improved: Tax Brackets mode now works like one tax return for the whole year. Traditional withdrawals, Roth conversions, taxable lump sums, brokerage sales and dividends climb the brackets together, share one standard deduction, and all count toward how much of your Social Security is taxed. It works the same way in the main projection, Monte Carlo and the stress tests. If you live mostly on Traditional money, or on brokerage sales while collecting Social Security, taxes will read higher than before and closer to what you would really owe
Improved: The Taxes column in the yearly table shows the tax your projection charged that year: income tax, tax on withdrawals and conversions, and capital gains and dividend tax
Improved: Monte Carlo and the stress tests count a run as short when your accounts cannot pay for the spending floor, so a Flexible Spending success rate reflects a budget you could live on. Scores with Flexible Spending on may read lower than before, and they are more realistic
Improved: Reinvested dividends add to your cost basis, so they are not taxed a second time when you sell
Improved: Required minimum distributions are based on the balance at the start of the year and come out before a same-year Roth conversion, the way the IRS does it. RMD money beyond your spending follows your Reinvest surplus choice
Improved: The income used for Medicare surcharges (IRMAA) counts Traditional withdrawals, taxable lump sums and realized gains, and the ACA income figure counts Traditional withdrawals. Monte Carlo and the stress tests no longer guess that income from your spending
Improved: Save to File and Share Links carry every setting and every account detail, including tax method, filing status, state tax, SEPP rate, account owners and values of zero, so a plan opens exactly as you left it
Improved: Shared links, advisor branding links and imported files are checked more carefully before anything loads, and a file that is not a BridgeToFI plan leaves your saved plan exactly as it was
Improved: SEPP/72(t) payments use the current IRS Single Life Expectancy table (2022 revision) in the 72(t) tool and in the projections
Improved: Social Security taxation follows the IRS Publication 915 worksheet for households with smaller benefits
Improved: Head of Household brackets now match the IRS figures ($201,750 and $256,200), and the live tax estimate uses Head of Household brackets for Head of Household filers
Improved: Spousal Social Security begins once the higher earner has claimed, matching Social Security rules. A partner with no benefit of their own receives it in the main projection, Monte Carlo and the stress tests, and the Income Floor chart shows it
Improved: My FI Report lists partner Social Security and pension, describes your Roth conversion and Flexible Spending setup, and is easier to read. If an ad blocker stops the report from loading, you get a clear message with what to do
Improved: Income Floor chart places partner income at the right point on your timeline when your ages differ and uses the claim age you picked
Improved: The RETURN figure in Portfolio Mix updates the moment you switch market scenarios or change a return rate
Improved: Clear All Data resets every setting on the page (your notes are kept)
Fixed: My FI Report now generates with Add Partner/Spouse turned on
Fixed: In Tax Brackets mode, your standard deduction stays what you set when you come back to the page, so single and Head of Household filers keep the right deduction on every visit. Saved plans that picked up the married amount are put back automatically, with a one-time note
Fixed: Partner Social Security now follows the Social Security switch, partner pension follows Pension Income, and the Medicare surcharge follows the healthcare section
Fixed: Flexible Spending keeps Medicare premiums in the main projection, matching Monte Carlo and the stress tests
Fixed: Monte Carlo and the stress tests honor a 0 you enter for bond, alternative and private equity returns, healthcare inflation and the standard deduction
Fixed: Loading a single or Head of Household plan from a file over a couple's plan keeps the right filing status
Fixed: A custom healthcare end age is remembered after a page reload
Fixed: Smart Insights tips for spending phases and partner income appear when they apply
Fixed: Reorder Layout saves your order, the portfolio sort choice is remembered, and Print explains when a pop-up blocker is in the way
Fixed: The demo opens in Advanced mode, and its sample income, events and expenses can be edited
Fixed: The claim-age tip no longer trips an error when the region is Australia or India
Fixed: A SEPP/72(t) plan that ends at 59.5 takes out only the half year it pays in its final year
Fixed: Notes you type are still there after a reload, even when nothing else on the page changed

v2.4 May 2026

New: Marketplace Subsidy Check panel in the healthcare section: enter your household size to see where your pre-Medicare income falls against the Federal Poverty Level, with subsidy tier guidance (premium tax credits, cost-sharing reductions, and the 400% cliff)
Improved: Healthcare section reworked for clarity: plainer labels and examples, the Medicare high-income surcharge explained in everyday terms, and click-to-expand explainers for both the surcharge and ACA marketplace subsidies
New: Per-year ACA MAGI is now computed in the projection engine, combining taxable income, realized capital gains, full Social Security, and Roth conversions
Fixed: Qualified dividends were double-taxed and double-counted in the RMD recalculation path and in the Monte Carlo and stress-test engines; dividends are now reinvested net of tax and excluded from spendable income across all three engines
Fixed: Head of Household 32% tax bracket threshold corrected to $256,225, matching the single-filer ceiling (IRS Rev. Proc. 2025-32)
Fixed: Cache-bust version tags on supabase-config.js and advisor-bridge.js were stale at v2.1.0 and now match the current release
Improved: Advisor portal data import now preserves scenario type, lock state, risk profile, and investment notes for clean export and import round-trip
Improved: Advisor portal data import shows clear failure counts and reasons when individual scenarios cannot be imported
Improved: Client metadata import is now a real merge: combines tags, keeps newer review dates, preserves existing notes, fills missing email and target retirement age
Fixed: Advisor portal bulk delete now updates the database alongside metadata so soft-deleted clients are filtered everywhere
Fixed: Advisor portal bulk export now includes all round-trippable fields, matching the import whitelist
Fixed: Compare scenarios dropdown and share link modal no longer show scenarios from soft-deleted clients
Fixed: Cross-site scripting risk on intake notification toast: client names from public intake forms are now properly escaped
Fixed: Race condition where settings auto-save could fire during bulk import operations
Improved: Welcome walkthrough animation combined into a single self-contained file for simpler hosting
Improved: Unified version numbering across calculator, advisor portal, and bridge script (all v2.4.0)

A free early retirement calculator for the years before 59½

BridgeToFI is a free FIRE and early retirement calculator. It shows, year by year, whether the money you can reach today (brokerage accounts, cash and Roth contributions) will carry you from the day you stop working until your retirement accounts open at 59½, and whether your whole portfolio lasts for the rest of your life.

Enter your accounts, your spending and the age you want to retire. The projection covers income tax (a flat rate or the 2026 US federal brackets), capital gains tax, Social Security at the claim age you pick, pensions, healthcare costs before Medicare, Roth conversion ladders, SEPP 72(t) payments and the Rule of 55. Monte Carlo then tests the plan against 1,000 random market paths, and the stress test replays real stretches of market history that began in 1929, 1966, 1973 and 2000.

Your numbers stay in your browser. There is no account to create and nothing to upload. If you make a share link, your plan travels inside the link, so share it only with people you trust. The calculator works for the United States, the United Kingdom, Canada, Australia, the Eurozone and India.

Common questions about early retirement

What is a FIRE bridge strategy?

A bridge strategy covers the gap between early retirement (typically age 35-50) and when you can access retirement accounts penalty-free at age 59½. It involves strategically withdrawing from taxable brokerage accounts, Roth IRA contributions, and other accessible funds to cover living expenses during this bridge period.

How much money do I need to retire early?

The traditional rule suggests saving 25 times your annual expenses (based on the 4% withdrawal rate from the Trinity Study). For example, if you spend $50,000 per year, you'd need $1.25 million. However, early retirees often need more due to the longer retirement period and healthcare costs before Medicare eligibility at 65. BridgeToFI calculates your exact number based on your age, spending, accounts, Social Security timing, and tax situation.

How much money do I need to retire at 50?

Retiring at 50 typically requires 25 to 30 times your annual expenses because your money needs to last 40+ years instead of 25. If you spend $5,000 per month ($60,000/year), you'd need roughly $1.5 to $1.8 million. But the real answer depends on your Social Security timing, tax strategy, healthcare costs before Medicare at 65, and how you split money between accessible accounts and locked retirement accounts like 401k and IRA. BridgeToFI models all of this year by year.

How much money do I need to retire at 45?

Retiring at 45 means covering roughly 14.5 years of expenses before your 401k and IRA unlock at 59½, plus decades after that. You need enough in accessible accounts (brokerage, Roth contributions, savings) to bridge those years, plus enough in retirement accounts for the rest of your life. A common target is 28 to 33 times your annual spending. BridgeToFI breaks this into phases so you can see exactly how much you need in each type of account.

How much money do I need to retire at 55?

Retiring at 55 gives you some advantages: the Rule of 55 may let you access your current employer's 401k penalty-free, and you only need to bridge 4.5 years to age 59½. Most planners target 20 to 25 times your annual expenses. At $6,000/month spending, that's roughly $1.44 to $1.8 million. BridgeToFI factors in Social Security at 62-70, pensions, healthcare costs until Medicare, and tax-efficient withdrawal sequencing.

Can I access my 401k before 59½ without penalty?

Yes, there are several legal ways. The Rule of 55 lets you withdraw from your current employer's 401k if you leave that job at 55 or older. SEPP (Section 72t) allows substantially equal periodic payments from any IRA at any age. Roth IRA contributions (not earnings) can be withdrawn anytime. A Roth conversion ladder lets you access converted amounts after a 5-year waiting period. BridgeToFI models all of these strategies and shows the impact on your plan.

What is a Roth conversion ladder and how does it work?

A Roth conversion ladder involves converting Traditional IRA or 401k funds to a Roth IRA over several years. After a 5-year waiting period, these converted amounts can be withdrawn tax and penalty-free at any age. For example, if you convert $40,000 in 2026, that money becomes accessible penalty-free in 2031. You start the ladder 5 years before you need the money, converting enough each year to cover future expenses.

What is the Rule of 55 for 401k withdrawals?

The Rule of 55 allows you to withdraw from your current employer's 401k or 403b plan without the 10% early withdrawal penalty if you leave that employer during or after the year you turn 55. Important: this only applies to the plan at the employer you are leaving, not old 401k plans or IRAs. If you roll the money into an IRA, you lose this benefit. BridgeToFI can model this as part of your early access strategy.

What is SEPP or 72(t) and how does it help early retirees?

SEPP (Substantially Equal Periodic Payments), also called 72(t), lets you take penalty-free withdrawals from an IRA at any age by committing to a fixed annual withdrawal schedule. You must continue for at least 5 years or until age 59½, whichever is longer. The amount is calculated based on your account balance and life expectancy. BridgeToFI includes a built-in 72(t) calculator and can model SEPP distributions in your retirement plan.

How do I cover expenses between early retirement and 59½?

The bridge period (retirement to 59½) is the core challenge of early retirement. You cover it using a combination of: taxable brokerage accounts (accessible anytime), Roth IRA contributions (penalty-free anytime), cash savings, rental income or other passive income, SEPP/72(t) distributions, and the Rule of 55 for 401k access. BridgeToFI's P1/P2/P3 priority system models exactly how these accounts deplete year by year.

What is the 4% rule and does it work for early retirement?

The 4% rule says you can withdraw 4% of your portfolio in year one, then adjust for inflation each year, and your money should last 30 years. The problem: it was designed for a 30-year traditional retirement, not a 40 to 50 year early retirement. For early retirees, a safer withdrawal rate is typically 3.25% to 3.5%. BridgeToFI runs Monte Carlo simulations with 1,000 scenarios to show your probability of success rather than relying on a single rule.

How do I plan for healthcare before Medicare at 65?

Early retirees need to cover health insurance from retirement until Medicare eligibility at 65. Options include ACA marketplace plans (where controlling your MAGI can qualify you for subsidies), COBRA continuation (up to 18 months), health sharing ministries, or a spouse's employer plan. ACA subsidies can save thousands per year if your income is managed carefully. BridgeToFI models healthcare costs as a separate expense that ends at your Medicare age.

What is the ACA subsidy cliff and how does it affect early retirees?

The ACA subsidy cliff is the income threshold above which you lose healthcare premium subsidies entirely. For early retirees, staying below this limit (400% of the Federal Poverty Level, about $62,600 for one person or $84,600 for a couple for 2026 coverage) can save $10,000 to $20,000+ per year in health insurance costs. Roth conversions, capital gains harvesting, and withdrawal sequencing all affect your MAGI. BridgeToFI includes an ACA/MAGI calculator to help optimize this.

Is my financial data secure on BridgeToFI?

Yes. In the free calculator all calculations happen locally in your browser, and your financial data is stored only in your browser's localStorage. There is no account and nothing to upload. You can export your plan as a file and clear it at any time. If you create a share link, the plan travels inside the link itself, so share it only with people you trust. The separate Advisor Portal stores client scenarios in an encrypted cloud database.

What is Monte Carlo simulation in retirement planning?

Monte Carlo simulation runs many scenarios (BridgeToFI runs 1,000) with randomized market returns based on historical patterns. Instead of assuming a fixed 7% return, it shows the probability of your plan succeeding across different market conditions, helping you understand the range of possible outcomes.

What are P1, P2, and P3 accounts in BridgeToFI?

BridgeToFI groups accounts by withdrawal priority. P1 (Priority 1) accounts like taxable brokerage and cash are accessed first and anytime. P2 accounts like Roth IRAs and HSAs are accessed next with some restrictions. P3 accounts like Traditional 401k and IRA are accessed last, typically after age 59½ to avoid penalties.

How does BridgeToFI differ from other FIRE calculators?

BridgeToFI focuses specifically on the bridge phase of early retirement, showing year-by-year projections of how different account types deplete over time. It supports progressive tax bracket modeling, spending phases, Roth conversion ladders, SEPP/72(t), Social Security timing, employer pensions, one-time events, expiring expenses, healthcare cost modeling, Monte Carlo simulation, and partner scenarios. It also supports 6 countries (US, UK, Canada, Australia, EU, India) with region-specific account types, pension systems, and unlock ages.

How do I know if I can afford to retire early?

You can afford to retire early when your accessible accounts (brokerage, Roth contributions, savings) cover your expenses until 59½, and your total portfolio (including 401k and IRA) sustains you through your full life expectancy. The key test is whether your P1 bridge funds last until your locked accounts unlock. BridgeToFI shows this with a green/yellow/red status indicator and year-by-year projections so you can see exactly when (or if) you run out.

Should I put money in a 401k or brokerage account for early retirement?

Both. The 401k gives you tax-deferred growth and often an employer match (free money). But 401k funds are locked until 59½ (with some exceptions). Brokerage accounts are taxable but fully accessible at any age, making them essential for your bridge period. The right balance depends on your early retirement age and spending needs. BridgeToFI's contribution shift feature lets you model redirecting some 401k contributions to brokerage to build a bigger bridge.

When should I take Social Security if I retire early?

You can claim Social Security between ages 62 and 70. Claiming at 62 gives you roughly 30% less than your full benefit at 67, while waiting until 70 gives about 24% more. For early retirees, delaying often makes sense because you can use the low-income years for tax-efficient Roth conversions and ACA subsidies. BridgeToFI lets you pick any claim age from 62 to 70, adjusts the benefit for you, and shows the impact on your total plan.

What is the best withdrawal order for early retirement?

The typical early retirement withdrawal order is: first, spend from taxable brokerage accounts (P1) since they have no age restrictions. Second, tap Roth IRA contributions if needed (P2). Third, once you reach 59½, access Traditional 401k and IRA funds (P3). During the early years, consider Roth conversions to fill low tax brackets. BridgeToFI automates this priority-based withdrawal sequencing and shows the tax impact year by year.

Does BridgeToFI work for UK retirement planning with SIPP and ISA?

Yes, BridgeToFI supports UK retirement planning with GBP currency, SIPP pension rules (access from 55 until 5 April 2028, 57 from 6 April 2028), ISA tax treatment, and State Pension integration with claim ages 66-68. The P1/P2/P3 framework maps to UK accounts: P1 for taxable investments, P2 for ISAs (tax-free, no age lock), P3 for SIPPs and workplace pensions.

Can I use BridgeToFI for Australian superannuation planning?

Yes, BridgeToFI supports Australian retirement planning with AUD currency and superannuation rules including preservation ages (55-60 depending on birth year). Super accounts map to P3 (locked until preservation age), while taxable investments and shares go in P1 for bridge planning. Super minimum drawdown rates are also modeled.

Does BridgeToFI support Canadian RRSP and TFSA retirement planning?

Yes, BridgeToFI supports Canadian retirement planning with CAD currency, RRSP/RRIF rules (mandatory conversion at 71), TFSA (tax-free with no age restrictions), and CPP/OAS pension integration with claim ages 60-70. RRSPs map to P3, TFSAs to P2, and non-registered accounts to P1.

Can BridgeToFI help with retirement planning in India using EPF and NPS?

Yes, BridgeToFI supports Indian retirement planning with INR currency, EPF and PPF rules, NPS (National Pension System) with unlock at 60, and accounts for Section 80C tax benefits. The tool helps model the bridge between early retirement and when provident funds become accessible.

How do I calculate my FIRE number?

Your FIRE number is the total portfolio value needed to retire and never run out of money. The simple formula is annual expenses multiplied by 25 (based on a 4% withdrawal rate). But this oversimplifies things for early retirees because it ignores taxes, Social Security, pensions, changing spending over time, and the bridge period before 59½. BridgeToFI calculates a more accurate number by modeling your actual accounts, tax situation, and income sources year by year.

What is Coast FIRE and how do I calculate it?

Coast FIRE is the point where your existing investments will grow to your full FIRE number by a traditional retirement age (often 60 to 65) without any additional contributions. Once you hit Coast FIRE, you only need to earn enough to cover current expenses. BridgeToFI shows your Coast FIRE number and the age you reach it in the FIRE panel, using your current portfolio, your contributions, your growth rate after inflation and a target age of 60.

Am I saving enough to retire early?

That depends on your age, spending, and how your savings are split between accessible and locked accounts. BridgeToFI shows you a clear green (on track), yellow (cutting it close), or red (not enough) indicator based on whether your accessible funds last until your locked accounts unlock. Enter your real numbers, including all accounts with balances and contributions, and you will see year-by-year projections instantly.
