Retirement Calculator

The Retirement Calculator projects how much your current savings and ongoing monthly contributions could grow to by the time you retire, based on an expected annual rate of return.

How the projection is calculated

Your current savings grow using compound interest, and your monthly contributions grow using the future value of an annuity formula. Combined:

FV = S(1+r)n + PMT × [(1+r)n − 1] / r

Where S is current savings, PMT is the monthly contribution, r is the monthly return rate, and n is the number of months until retirement.

Example: Starting at age 30 with $20,000 saved, contributing $500/month at a 7% average annual return until age 65 (35 years), your projected balance would be roughly $1,130,650 — of which $230,000 came directly from contributions and about $900,650 from investment growth.

Important caveats

This is a simplified projection that assumes a constant rate of return and doesn't account for inflation, taxes, fees, or market volatility. Actual results will vary. Pair this with our Inflation Calculator to estimate purchasing power, or the Investment Calculator for shorter-term goals.
