Calculate how much you need to save now to achieve financial independence
Coast FIRE Breakdown
Financial independence and early retirement (FIRE) have become increasingly popular goals for individuals seeking to take control of their financial futures. One of the most intriguing strategies within the FIRE movement is Coast FIRE, which allows you to stop saving for retirement once you’ve accumulated enough investments to grow on their own until retirement age. But how do you know when you’ve reached this milestone? Enter the Coast FIRE Calculator—a powerful tool designed to help you determine how much you need to save now to achieve financial independence without further contributions. In this article, we’ll explore what Coast FIRE is, how the calculator works, and why it’s an essential tool for anyone pursuing financial freedom.
What is Coast FIRE?
Coast FIRE is a financial strategy where you save and invest enough money early in life so that, without adding any more contributions, your investments grow to support your retirement. Once you reach this point, you can “coast” until retirement age, focusing on covering your living expenses without worrying about saving for the future.

Why Use a Coast FIRE Calculator?
The Coast FIRE Calculator simplifies the complex math behind this strategy, helping you:
- Determine Your Savings Goal: Calculate how much you need to save now to reach your retirement target.
- Plan for the Future: Understand how your investments will grow over time.
- Make Informed Decisions: Adjust variables like retirement age, annual expenses, and expected returns to explore different scenarios.
- Achieve Peace of Mind: Know exactly when you can stop saving and start coasting toward retirement.
How the Coast FIRE Calculator Works
The calculator uses four key inputs to determine your Coast FIRE number:
- Current Age: Your age today.
- Retirement Age: The age at which you plan to retire.
- Annual Expenses in Retirement: Your expected annual expenses during retirement.
- Expected Annual Return: The average annual return you expect from your investments.
Using these inputs, the calculator computes:
- Required Savings Today: The amount you need to save now to reach your retirement goal.
- Future Value Needed: The total amount your investments need to grow to by retirement age.
The Formula Behind the Calculator
The calculator uses the future value formula to determine how much your savings will grow over time:
Copy
Future Value = Present Value × (1 + r)^n
Where:
- Present Value = Required savings today
- r = Expected annual return (as a decimal)
- n = Number of years until retirement
To find the required savings today, the formula is rearranged:
Copy
Present Value = Future Value / (1 + r)^n

2. Flexibility in Financial Planning
Once you reach Coast FIRE, you can choose to:

Common Mistakes to Avoid
- Underestimating Expenses
Be realistic about your annual expenses in retirement. Include healthcare, travel, and other discretionary spending. - Overestimating Returns
Use a conservative estimate for your expected annual return (e.g., 6–7%) to avoid overestimating your growth. - Ignoring Inflation
Inflation can erode your purchasing power over time. Consider adjusting your annual expenses for inflation. - Forgetting Taxes
Taxes can impact your investment growth and withdrawals. Factor in tax-advantaged accounts like IRAs or 401(k)s.
