Calculate your Coast FIRE number and see when you can stop adding money to your retirement savings. Use Bravo Calc’s Coast FIRE calculator to plan your journey to financial freedom.
🏖️What is Coast FIRE?
Coast FIRE represents the point where you have enough invested that compound growth alone will fund your retirement, even if you never save another dollar. The Coast FIRE calculator helps you determine this crucial milestone in your financial independence journey.
Unlike traditional FIRE (Financial Independence, Retire Early), Coast FIRE allows you to "coast" by reducing your savings rate while still working until traditional retirement age. Our Coast FIRE calculator shows exactly when you reach this financial freedom point.

Expert Tips for Coast FIRE Success
Optimization Strategies:
- Start Early: The Coast FIRE calculator shows that starting investments in your 20s dramatically reduces the required Coast FIRE number due to longer compound growth periods.
- Maximize Tax-Advantaged Accounts: Use 401(k), IRA, and HSA contributions to accelerate your path to Coast FIRE while reducing current tax liability.
- Conservative Return Assumptions: Use 6-7% expected returns in the Coast FIRE calculator for more conservative planning, despite historical market averages being higher.
- Regular Recalculation: Update your Coast FIRE calculations annually to account for market performance, lifestyle changes, and goal adjustments.
Common Mistakes to Avoid:
- Overly Optimistic Returns: Don't use unrealistic return assumptions in your Coast FIRE calculator that could lead to undersaving.
- Ignoring Inflation: Account for inflation in both your Coast FIRE number calculation and expected future expenses.
- Lifestyle Inflation: Avoid increasing expenses proportionally with income, which can push your Coast FIRE target higher.
- Neglecting Healthcare Costs: Factor in potentially higher healthcare expenses in retirement when calculating your Coast FIRE number.
Frequently Asked Questions
What's the difference between Coast FIRE and regular FIRE?
Regular FIRE requires accumulating 25x your annual expenses to retire immediately. Coast FIRE is the amount needed today that will grow to your FIRE number by traditional retirement age through compound growth alone. The Bravo Calc Coast FIRE calculator shows this is typically much less than your full FIRE number, allowing you to reduce savings pressure while still securing your retirement.
How accurate is the Coast FIRE calculator?
The Coast FIRE calculator provides estimates based on your inputs and assumptions about future market returns. While historical market data supports long-term growth assumptions, actual results will vary. Use conservative return estimates (6-7%) and regularly update your calculations. The Bravo Calc includes sensitivity analysis to show how different scenarios affect your Coast FIRE timeline.
Can I still save money after reaching Coast FIRE?
Reaching Coast FIRE means you've secured your minimum retirement needs, but additional savings can provide earlier retirement, higher retirement income, or greater financial security. Many people continue saving at a reduced rate after Coast FIRE, using the psychological freedom to pursue other goals or take calculated career risks.
What return rate should I use in the Coast FIRE calculator?
Conservative planners use 6-7% for mixed portfolios, while more aggressive assumptions might use 8-10% for stock-heavy portfolios. The S&P 500 has historically returned about 10% annually, but this includes significant volatility. The Bravo Calc Coast FIRE tool allows you to test different return scenarios to see how they affect your Coast FIRE number and timeline.
Should I include Social Security in my Coast FIRE calculation?
This depends on your age and confidence in Social Security's future. Younger investors might exclude it for conservative planning, while those closer to retirement might include estimated benefits. The Coast FIRE calculator can be run with and without Social Security to show the difference. Remember that Social Security typically replaces only 40% of pre-retirement income for average earners.
How often should I recalculate my Coast FIRE number?
Review your Coast FIRE calculation annually or after major life changes (marriage, children, job changes, significant market movements). Market volatility, lifestyle changes, and goal adjustments can all affect your Coast FIRE number. The Bravo Calc makes it easy to update your calculations and track progress toward your Coast FIRE milestone over time.
