FIRE Calculator — United States

Work out the earliest age you could retire and stay retired. This model runs your real cash flow year by year — tax, employer contributions, investment growth and fees — then tests every possible retirement age to find the first one that survives all the way to your planning horizon.

Why you can retire on less than the 4.0% target

The $1,500,000 target is the simple 4.0% rule — a portfolio big enough to live off indefinitely. Your plan reaches $1,338,147 and still works, because it only has to last to age 95, and it keeps compounding the whole time you are drawing on it. That is a reasonable way to plan, but it leaves less margin for a bad run of markets — worth testing in the drawdown simulator.

The bridge: 6.5 years before 401(k) unlocks

Retiring at 53 means funding everything from taxable brokerage until age 59½.

The bridge holds

Your accessible investments cover every year before age 59½, so the plan does not depend on reaching 401(k) + ira early.

How this works

When can I retire, and will it actually hold?

Why this differs from a simple 4% rule

Multiplying your spending by 25 gives you a target, not a plan. It ignores the fact that a large share of your wealth is locked away until preservation age, that your contributions are taxed differently on the way in, and that fees compound against you for decades. This calculator simulates all of it.

How the earliest retirement age is found

The model builds your full accumulation path, then for every candidate age it runs a complete drawdown to your planning horizon. The earliest age where the money never runs out — including through the bridge years before your retirement accounts unlock — is your FIRE age.

What to do with the answer

Treat it as a direction, not a date. Move one input at a time — spending, savings rate, expected return — and watch how many years it buys you. Spending is almost always the most powerful lever, because every dollar cut both raises your savings and lowers the target you are saving towards.
