Annuity Formula

We provide a wide variety of tutorials, techniques, examples, formulas, tables, and calculators all relating to use of annuity formulas in time value of money calculations for accounting and business finance.

The time value of money is simply the idea that as a result of interest (i), the value of a payment today (present value), is not equal to the value of the same payment in the future (future value).

What are Annuities?

An annuity simply refers to a series of equal periodic payments (Pmt) made for a specified number of periods (n). An annuity formula is used to calculate either the future value (FV) or the present value (PV) of the annuity based on an discount rate (i).

In order to be able to add annuity payments from different time periods together, all the payments need to be brought together at the same time period. To do this we need to perform discounting or compounding operations using an annuity formula.

The present value of an annuity payment can be converted into a future value by compounding, and likewise, the future value of an annuity payment can be converted to a present value by discounting.
