About this app

Enter a starting amount and an assumed constant rate. Choose compounding frequency and the timing and frequency of recurring deposits. Compare yearly balances, deposits, interest and inflation-adjusted value, or estimate the time or deposit needed for a target. Save scenarios locally or copy a summary or yearly CSV. These are mathematical illustrations, not forecasts, guaranteed returns or financial advice.
Model compound interest, recurring deposits and a savings target offline.
