Compound Interest Calculator

Retirement Calculator

Retirement success usually comes down to three levers: how long your money compounds, how much you contribute along the way, and the return you earn on it. This calculator isolates those levers so you can see how changing each one shifts your projected balance on the day you retire.

Reading your retirement projection

Years between now and retirement is the single biggest lever most people overlook — every additional year of compounding can add tens of thousands of dollars in pure interest. The default 7% return reflects a mix of historical stock- and bond-market returns after inflation, but you can lower it to a more conservative 5% if you tilt heavily toward fixed income.

This projection shows the balance on the day you retire. It does not account for taxes, required minimum distributions, inflation-adjusted withdrawals, or Social Security. Use it alongside a withdrawal calculator to plan the income side of retirement.
