How to read it

Each row is the present value of the same target, discounted at the real return for the years remaining. Younger rows look small because they have more compounding left, not because the retirement is cheaper.

Frequently asked questions

What is a Coast FIRE number by age?
The amount you need invested today, at that age, so that compounding alone reaches your retirement target by the chosen retirement age. Younger ages need less invested today because they have more years of growth.
