Free calculator showing when you can stop saving for retirement and let investment growth reach your goal.

Coast FIRE Planner is a free calculator that helps you determine when you can stop saving for retirement. It calculates your coast date—the month your portfolio will reach your target amount through growth alone—and shows the odds of success across 1,000 simulated market scenarios. The tool includes what-if scenarios to see how changes like higher savings, longer working years, or lower returns affect your timeline.
The calculator accounts for investment fees, contribution raises, inflation, and safe withdrawal rates. It provides a share link to compare plans with others and requires no sign-up. Results are educational estimates based on your assumptions.

The calculator defaults to 7% before inflation. Use a lower number if more of your money is in bonds or cash, and check how the result changes with the what-if rows.
The calculator simulates 1,000 possible markets with yearly swings of about 15% around your expected return, and counts how many reach your FIRE number by your retirement age.
It comes from studies of 30-year retirements. Many planners use 3–3.5% for longer ones. Change the withdrawal rate under Assumptions to see the effect.
Not directly. Lower your yearly spending by the pension you expect, in today's money.
