Find the future value or present value of a level yearly payment at a constant annual rate.

Use this annuity calculator for a savings plan, pension contribution, or payout stream where the same amount is paid once a year. Payments are treated as end-of-year (an ordinary annuity), not beginning-of-year (annuity due).
Future-value mode compounds the payments forward: FV = PMT × ((1 + r)^n − 1) / r. Present-value mode discounts them back: PV = PMT × (1 − (1 + r)^(−n)) / r. If the rate is essentially zero, the result is simply PMT × years. Type 5 for a 5% annual rate.
This is one payment per year. For monthly deposits, use the compound-interest calculator instead.
Payment / year: The same amount paid or received each year.
Rate (%): Annual interest or discount rate as a percent.
Years: How many yearly payments.
Mode: Future value if you are accumulating; present value if you are valuing a stream of payments.
Value: The FV or PV of the annuity.
