How to use the annuity calculator
Enter payment amount, annual interest rate, term in years, and how many payments per year. Choose ordinary (end of period, default) or annuity-due (start of period). PV and FV are computed.
Formula & explanation
PV (ordinary) = PMT × (1 − (1+i)^−n) ÷ i. FV (ordinary) = PMT × ((1+i)^n − 1) ÷ i. Annuity due: multiply by (1 + i).
Examples
1,000/month for 10 yr at 5% APR (ordinary): PV ≈ 94,281, FV ≈ 155,282.
