The calculator uses compound interest to show how your savings will grow over the selected time period. You can adjust the inputs to see how different amounts and time periods affect your savings.

Formula Used

The calculator uses the compound interest formula to calculate your savings:

Compound Interest Formula

A = P × (1 + r/n)^(nt)

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the time the money is invested or borrowed for, in years

For this calculator, we assume the interest is compounded annually (n = 1) and use a 2.5% annual interest rate (r = 0.025).

Worked Example

Let's say you deposit $1,000 in a savings account with a 2.5% annual interest rate. Here's how your savings will grow over 5 years:

Example Calculation

Initial deposit (P) = $1,000

Annual interest rate (r) = 2.5% = 0.025

Time period (t) = 5 years

Compounding frequency (n) = 1 (annually)

Future value (A) = 1000 × (1 + 0.025/1)^(1×5) = $1,130.45

Total interest earned = $1,130.45 - $1,000 = $130.45

After 5 years, you would have $1,130.45 in your savings account, earning $130.45 in interest.
