Frequently asked questions
- What is Coast FIRE?
- Coast FIRE is the amount you need invested today so that, with no further contributions, normal market growth reaches your full FIRE number by retirement age. Once you hit it, you only need to cover current expenses.
- How is the Coast FIRE number calculated?
- Take your full FIRE number (annual expenses ÷ withdrawal rate) and discount it back to today over the years until retirement using your expected real return: FIRE ÷ (1 + r)^n.
- What return should I use?
- Use a real, after-inflation return so your answer stays in today's dollars. A diversified stock portfolio has historically returned roughly 7% real; use a lower figure to be conservative.
- Does this include future contributions?
- No. Coast FIRE is specifically the point where no further contributions are required. The projection assumes you stop contributing and let the portfolio grow.
