When can you stop contributing and let compounding do the rest?

Your Coast FIRE number is the balance where you never need to contribute another dollar to retirement — compounding alone gets you there.

What is Coast FIRE?

Once you reach your Coast FIRE number, your investments will grow to your retirement target on their own — without any additional contributions. You can redirect that monthly savings to other goals: a home, travel, or simply working less. You are not fully retired, but you have bought yourself financial freedom to choose.
