Annuity Calculator
An ordinary annuity is a sequence of equal payments at the end of each period. The calculator returns the future value FV = PMT · ((1 + r)ⁿ − 1) / r, or the present value PV = PMT · (1 − (1 + r)⁻ⁿ) / r, depending on what you select.
Frequently asked questions
What is the difference between FV and PV?
FV is the total accumulated at the end of the annuity; PV is the lump sum today that is financially equivalent to those future payments.
What rate should I enter?
The rate per period — not the annual rate. For monthly payments under an annual rate of 5%, use 5/12 ≈ 0.4167%.
Does this handle annuity-due?
This calculator treats an ordinary annuity (payments at the end of each period). To convert to annuity-due, multiply the result by (1 + r).
