## What does it do?

This future value of an annuity calculator works out the future value (FV) of a regular sum of money (Pmt) received at the end of each of n periods, using a discount rate i.

## Formula

The calculator uses the future value of an annuity formula as shown below:

FV = Pmt x ( (1 + i)^{n}- 1 ) / i

The Excel future value of an annuity calculator, available for download below, is used to compute the future value by entering details relating to the regular payment, discount rate and the number of periods. The calculator is used as follows:

### Step 1

Enter the regular payment amount (Pmt). The regular payment is the amount received at the end of each period for n periods. The amount must be the same for each period.

### Step 2

The rate should be for a period, so for example, if the period is a year, then the rate should be the yearly rate.

Enter the number of periods (n). The number of periods is entered. A period can be any term (month, year etc), but must be consistent with the discount rate provided (see step 2).

### Step 4

The future value of an annuity calculator works out the future value (FV). The answer is the value at the end of period n of an a regular sum of money received at the end of each of the n periods, at a discount rate of i.
