Coast FIRE number at 48 by spending and retirement age
The amount invested today at 48 that grows, untouched, to 25 times the yearly spending by the retirement age, at a 5% real return. Retiring earlier leaves fewer years to compound, so the number rises.

How it is worked out
The target is the yearly spending divided by the withdrawal rate: $60,000 at 4% is $1,500,000. The Coast FIRE number is that target discounted back to today at the real return, the return after inflation, so every figure is in today’s dollars. It is the Coast FIRE calculator’s own math on its defaults: a 4% withdrawal and a 5% real return, about a 7% stock-heavy return less 2% inflation. Social Security or a pension lowers the target; enter them in the calculator.
