How the calculation works

Formula

Monthly Rate = (1 + Annual Return)^(1/12) − 1; Projected Fund = Current Savings × (1 + Monthly Rate)^n + Monthly Contributions × Annuity Factor

Monthly contributions occur at each month end. Annual return is converted to an effective monthly rate. Retirement income target uses level end-of-month withdrawals with no inflation adjustment during retirement. Returns and inflation are assumptions, not forecasts; this is educational, not personalized investment advice.
