Coast FIRE Calculator: Stop Saving and Still Retire

Coast FIRE is the point at which your existing portfolio will compound to your full FI number by retirement age, even if you never save another pound.

The calculator works out the smaller pot you need today based on your age, target age, expected return, and FI number.

Hitting Coast FIRE in your 30s gives you the option to take a lower-paying job, reduce hours, or take a career break without derailing retirement.

It is the single most useful FIRE milestone for most people because it is reachable years before full FI.
