Find out when you can stop saving — let compound interest carry you to retirement.
Coast FIRE is a branch of the FIRE movement. Core idea: once your investment principal reaches a certain point, even if you stop saving, compound interest alone will grow it to your FIRE target by traditional retirement age.
Coast FIRE Number = FIRE Target / (1 + annual return)^years to retirement
If you have $184,000+ today, congratulations — you've achieved Coast FIRE! No need to save another dollar; compound interest will get you to $1M in 25 years.
