What is Compound Interest?

Compound interest allows your money to grow faster than simple interest. The interest earned in each period is added to the principal, so future interest is calculated on an increasing amount. The more frequently interest is compounded, the higher the returns.

How Compound Interest Works

Interest earned during each compounding period is added to the principal. For example, if interest is compounded monthly, every month the earned interest is added to the balance, increasing the base for the next month’s interest calculation. This compounding effect significantly increases your wealth over time.

Compound Interest Formula

A = P (1 + r/n)^nt
Where:
P = Principal amount invested
r = Annual interest rate (decimal)
n = Number of compounding periods per year
t = Time in years
A = Total amount including interest
