What is Compound Interest?

Compound interest is the interest on a loan or deposit, calculated based on both the initial principal and the accumulated interest from previous periods. This means your investment grows faster over time.

Formula

A = P(1 + r/n)^nt
Where:
P = principal amount
r = annual interest rate (decimal)
n = times compounded per year
t = number of years
A = amount after time

Example

Investing $1,000 at an annual rate of 5%, compounded monthly for 10 years, will grow to approximately $1,647.01.
