FIRE Calculator

Find the portfolio that covers your spending and how long it takes to build it.

Portfolio needed

How it works

The target is annual spending divided by the withdrawal rate; the time to reach it comes from growing current savings while adding the yearly amount.

Example

Spending $48,000 at a 4% withdrawal rate needs $1,200,000, about 17.3 years away from $120,000 while saving $30,000 a year at 6%.

Frequently asked questions

Do these tools use live market data?

No. Nothing is fetched; you enter the prices, rates, and assumptions yourself.

Does the calculator send my numbers anywhere?

No. The calculation runs locally in your browser.

Are projected returns guaranteed?

No. A projection repeats the rate you entered every year, which real markets never do.
