Common questions

Coast FIRE Calculator FAQs

What does Coast FIRE mean?

It means existing investments may have enough time to grow to the retirement target without further contributions.

Why use a real return?

A return after inflation keeps the spending target and projected values in today’s money.

Does reaching Coast FIRE mean I can stop working?

Not necessarily. It usually means future retirement investing may no longer be required, while current living costs still need funding.
