Formula Used

The calculator uses the 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 unit t
t = the time the money is invested or borrowed for, in years

For simple interest, the formula is:

A = P(1 + rt)

Worked Example

Let's say you deposit $1,000 in a savings account with a 3% annual interest rate, compounded monthly, for 5 years.

Principal (P) = $1,000
Annual interest rate (r) = 3% or 0.03
Compounding frequency (n) = 12 (monthly)
Time (t) = 5 years

Using the compound interest formula:

A = 1000(1 + 0.03/12)^12×5

A ≈ $1,159.27

Your total earnings would be $159.27 over the 5-year period.
