Compound Interest Calculator is a powerful tool designed to show how your investments can grow over time by calculating interest on both the initial amount and the interest already earned.
It’s perfect for anyone looking to maximize their savings or understand how compounding works in long-term investments.
What is Compound Interest?
Compound interest is often referred to as “interest on interest.” Unlike simple interest, where you earn interest only on the initial principal, compound interest allows you to earn on both the principal and any previously earned interest.
This means your money can grow faster over time, making compounding one of the most effective ways to build wealth.
Compound Interest Formula
The formula to calculate compound interest is:
A = P (1 + r/n)^(nt)
Where:
- A is the amount of money accumulated after n years, including interest
- P is the principal amount (the initial investment)
- r is the annual interest rate (as a decimal)
- n is the number of times interest is compounded per year
- t is the number of years the money is invested or borrowed
Example Calculation
Let’s say you invest 5,000 at an annual interest rate of 5%, compounded quarterly for 4 years. Using the formula:
A = 5000 (1 + 0.05/4)^(4×4) = 6,099.45
At the end of 4 years, your investment would grow to 6,099. Here, compound interest allows you to earn more than you would with simple interest because your earnings are reinvested.
