Savings Rate Calculator

Your savings rate is the share of your take-home pay that you save and invest, calculated as annual savings divided by annual after-tax income. Saving 30,000 from 100,000 of take-home pay is a 30 percent savings rate.

A higher savings rate does two things at once: it lowers the spending you need to fund, which shrinks your FI number, and it grows your portfolio faster. That combination means years to financial independence fall sharply as your rate rises, almost regardless of income.

We compute your FI number as annual spending divided by your safe withdrawal rate, then simulate your yearly savings compounding at the expected return until the balance reaches that target. The result is the number of whole years it takes.

Many plans use a real, inflation-adjusted return of around 5 percent and the 4 percent withdrawal rule, which implies an FI number of 25 times your annual spending. These are defaults you can change. Results are estimates, not guarantees.

If your annual savings are zero, the portfolio never reaches your FI number, so the calculator shows years to FI as never. Increasing your savings even a little gives a finite, and often surprisingly shorter, timeline.
