Compound Interest Calculator
Compound interest is often called the "eighth wonder of the world" because of its incredible power to grow wealth over time. Our Compound Interest Calculator helps you visualize how your money can grow through the magic of compounding.
What is Compound Interest?
Compound interest is the interest calculated on the initial principal and the accumulated interest from previous periods. Unlike simple interest, which is calculated only on the principal amount, compound interest grows exponentially because you earn interest on your interest.
The Compound Interest Formula
The basic compound interest formula is:
- A = Final amount
- P = Principal (initial amount)
- r = Annual interest rate (decimal)
- n = Number of times interest compounds per year
- t = Time in years
