FIRE Calculator

What FIRE means

FIRE (Financial Independence, Retire Early) describes a point where your investment wealth is large enough that its return can cover your living costs without paid work. The target is usually derived from annual expenses: the lower your spending, the smaller the wealth needed.

Cutting consumption, for example, both speeds up saving and lowers the required FIRE number, so the goal gets closer from two directions.

What you enter and what you get

Enter your current annual expenses, your savings so far, your monthly contribution and an expected return. The calculator returns the required FIRE number and an estimate of how many years away financial independence is.

You can try different savings rates and spending levels to see how they bring the goal forward or push it back.

Who it is for

It works for people interested in the FIRE movement and anyone planning early financial independence. It turns an often abstract goal into a measurable number and timeline.

Good to know

The calculator assumes a steady return and stable expenses, while in reality both vary. Use a cautious return assumption and keep the long-term effect of taxes and inflation in mind.
