How retirement savings are calculated

This calculator uses compound interest with monthly compounding. Your existing savings grow as a lump sum: FV = P × (1 + r)^n. Monthly contributions grow as an annuity: FV = PMT × ((1 + r)^n − 1) / r. The historical US stock market average return is roughly 7% after inflation.
