When could you reach FIRE?

Explore when your investments could reach the amount you need to make paid work optional, based on what you have saved and what you plan to add.

Monthly spending kept constant in today’s purchasing power.

Annual withdrawal assumption used to calculate the FIRE target.

Invested balance at month zero.

Amount invested on each contribution date.

Effective nominal return after fees.

Inflation applied to the FIRE target.

Whole-year age used only for an approximate age result.

The bounded period searched for the first target crossing.

Advanced contribution assumptions
Contribute monthly or once per year; annual amounts are not divided into monthly deposits.
Beginning deposits enter before growth; end deposits enter after growth for that period.
Choose fixed nominal contributions or amounts linked to cumulative inflation.

FIRE target reached in 355 months.

What the estimated date helps you plan

A FIRE number gives you a target; this calculator explores how long reaching it could take. Enter your expected living costs, existing investments and future contributions, then choose assumptions for investment growth and rising prices. It shows the first month the projected investment pot reaches your target.

Change one assumption at a time to see how saving more, spending less or waiting longer changes the result. Rising prices also raise the future amount needed to afford the same lifestyle. The estimated age is approximate because the calculator uses your current age, not your birth date.

Reading your result

If your investments already meet the target, the result starts at month zero. If the target is not reached within the years you selected, that means it was not reached in this scenario—not that financial independence is impossible. The annual table shows the path used to reach that conclusion.

For example, spending of 3,000 a month with a 4% withdrawal assumption starts with a target worth 900,000 in today’s money. The date depends on your starting investments, deposits, growth assumption and inflation. Compare the target with FIRE number.

What could change the outcome

Actual investments do not grow smoothly each month. Market falls, changes in income and spending, taxes and pensions could all change your timeline. Reaching the estimated target does not prove your money will last through retirement; this calculator does not simulate spending down the portfolio. Use Coast FIRE to explore a future target with no further contributions.

The maths behind the estimate

The starting target is annual spending divided by the withdrawal rate. Each month, the calculator increases the target for inflation and compares it with the projected investment balance. It checks the starting balance first, then reports the first month that meets the target within your selected years. Growth and contribution timing follow the methodology.
