Calculate the future value of a series of regular payments (an annuity), based on your contribution, rate, and time period.
The Annuity Calculator projects the future value of a stream of equal periodic payments, such as regular retirement or savings contributions.
Unlike a simple future value calculation on a lump sum, this tool accounts for money added at the end of every period, each earning interest for the time remaining.
FV = PMT × [ ((1 + r/n)^(n×t) − 1) ÷ (r/n) ], where PMT is the payment per period, r is the annual rate, n is payments per year, and t is years.
Contributing $200 a month for 15 years at 5% annual interest builds a future value of roughly $53,700, of which about $17,700 is interest earned.
An annuity is a series of equal payments made or received at regular intervals — this calculator estimates either the future value of contributions or the payout from a lump sum.
In an ordinary annuity, payments happen at the end of each period; in an annuity due, they happen at the start, which slightly increases the future value since each payment earns interest for one extra period.
No — it's a mathematical estimate based on the rate and payment amounts you enter. Real annuity products often carry fees that reduce actual returns.
