Formula Used

The calculator uses the following formulas to determine your interest:

Simple Interest: A = P(1 + rt) Where: A = Final amount P = Principal amount (initial deposit) r = Annual interest rate (in decimal) t = Time the money is invested for (in years) Compound Interest: A = P(1 + r/n)^(nt) Where: A = Final amount P = Principal amount (initial deposit) r = Annual interest rate (in decimal) n = Number of times interest is compounded per year t = Time the money is invested for (in years)

For compound interest calculations, the calculator assumes interest is compounded annually unless otherwise specified.

Worked Example

Let's say you deposit $1,000 in a savings account with an annual interest rate of 5%. You want to know how much you'll have after 3 years with compound interest.

Using the compound interest formula:

A = 1000(1 + 0.05/1)^(1*3) = 1000(1.05)^3 = 1000 × 1.157625 = $1,157.63

Total interest earned: $157.63

This example shows how compound interest can grow your savings over time. The more time your money stays in the account, the more interest you'll earn.
