This **annuity calculator** calculates the future value (or annuity value) of a set of payments made at the end of each term based on an annual contribution amount and annual interest rate.

Example:

One sample use of this calculator is to determine how much you’ll have at the end of 25 years if you contribute $5000 at the end of every year for 25 years and it earns an annual interest rate of 8%.

### Definitions:

**Annual Contribution** is the amount in dollars (and cents) that you plan to contribute each year, at the end of the year. Example: If you plan to contribute $5000 per year, then type, 5000. Do not include the dollar sign.

**Annual interest rate** is the rate of interest per year that you estimate to make or earn. Example: If you expect an 8% rate of return, then type, 8. If you expect a 5.5% rate of return, type 5.5. I’ve only allowed up to 2 decimals.

**Years of Compounding** is the number of years you expect to contribute and is equal to the number of payments you plan to make. Example: If you plan to contribute for 25 years, then type, 25.
