What is COAST FIRE?

COAST FIRE (Financial Independence Retire Early) is a strategy where you save enough money early in your career that you no longer need to contribute to retirement accounts to reach your financial independence goal. The existing investments continue to grow through compound interest until retirement.

Once you reach your COAST number, you can reduce your work hours, switch to a lower-paying but more fulfilling job, or simply redirect your savings to other goals while your retirement takes care of itself.
