Question 1

What is FIRE (financial independence)?

Accepted Answer

FIRE — Financial Independence, Retire Early — is the point where your savings can cover your living costs, so working becomes optional. This calculator estimates how many years of saving it takes to reach your target, and whether the money lasts once you start withdrawing.

Question 2

How is the projection calculated?

Accepted Answer

It compounds your starting capital and monthly contribution at a real, inflation-adjusted return until you reach your target, then models withdrawals to check whether the balance is sustainable, lasts your horizon, or depletes. All figures are shown in today's money.

Question 3

Do I need an account, and is my data saved?

Accepted Answer

No account is required and nothing you type is saved — the whole calculation runs in your browser. It is an estimate for planning, not financial advice.
