INTERACTIVE TOOL

FIRE Calculator

Financial independence is the point where your investments can cover your spending for good. Set what you have, what you save, and what you spend, and see the age you could reach it. By default the calculator uses the classic 4% rule: your nest egg is 25 times your yearly spending, a pot big enough that investment returns cover your withdrawals for life. Open Fine-tune to change the expected return, adjust the safe withdrawal rate, set a different retirement spending, or switch to a drawdown that runs your money down to a chosen age. Every figure is in today's money, since returns are shown after inflation.

How it works

Each year your savings grow by your real return and you add what you don't spend (income minus spending). The tool finds the earliest age your balance reaches your FIRE number. By the 4% rule that number is 25 times your yearly spending, a pot large enough that returns cover your withdrawals for good. Switch to spend to an ageand it instead sizes the pot to run down to about zero by the age you pick. Returns are real (after inflation), so every figure stays in today's money.
