How the Annuity Calculator Works
An annuity is a series of equal payments made at regular intervals. This calculator finds two things: the future value — what those payments grow to if each one earns interest until the end — and the present value, the lump sum today that is worth the same as the whole stream of future payments. Both come from the standard time-value-of-money formulas.
The interest rate is split into a per-period rate (annual rate divided by payments per year), and the number of periods is years times payments per year. With an ordinary annuity payments land at the end of each period; with an annuity due they land at the start, so every payment earns one extra period of interest and both values are a touch higher.
FV = PMT × [(1 + i)n − 1] ÷ i PV = PMT × [1 − (1 + i)−n] ÷ i
Frequently Asked Questions
What is the difference between present and future value?
Future value is what a stream of payments will be worth at the end, after earning interest. Present value is the single amount today that equals that stream, discounting each future payment back to now.
What is an annuity due?
An annuity due pays at the start of each period rather than the end — rent and many pensions work this way. Because each payment earns one extra period of interest, its present and future values are slightly higher than an ordinary annuity.
Does this include taxes or fees?
No. It shows the pure time-value-of-money result. Real insurance annuities carry fees, surrender charges and tax rules that vary by product, so use this as a baseline, not a quote.
