Formula Used

The annuity savings account calculator uses the following formula to calculate future value:

Future Value Formula

FV = P × [((1 + r/n)^(n×t) - 1) / (r/n)] × (1 + r/n)

Where:

FV = Future Value of the annuity
P = Monthly contribution amount
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year (12 for monthly)
t = Number of years

This formula accounts for compound interest, which means your money grows not just on the principal amount but also on the accumulated interest.

Worked Example

Let's say you want to calculate your future savings with these parameters:

Monthly contribution: $200
Annual interest rate: 5%
Number of years: 10

Using the formula:

Calculation Steps

1. Convert annual rate to monthly: 5% ÷ 12 = 0.0041667

2. Number of payments: 10 years × 12 = 120 months

3. Apply the formula: FV = 200 × [((1 + 0.0041667)^120 - 1) / 0.0041667] × (1 + 0.0041667)

4. Result: Approximately $33,500

This example shows how $200 per month at 5% interest over 10 years grows to about $33,500.
