Lean FIRE target capital

Retirement
The numbers shown come from a sample profile for illustration – in the calculator you see your own values.

The Lean FIRE target capital is the wealth you need to live permanently on your living costs alone – without lifestyle spending. Unlike the regular FIRE target capital (living costs + lifestyle), all leisure spending is deliberately left out here.

Lean FIRE allows a considerably earlier exit from working life – bought with a minimal lifestyle. It is a real milestone: once you reach Lean FIRE, you can stop working at any time, but without a financial cushion for extras.

Like the regular FIRE target capital, the Lean FIRE number already includes taxes and health-insurance costs from the FIRE net calculator.
