Compound Interest Calculator

Calculate compound interest over time for savings 📈

How to Calculate Compound Interest

The calculator uses the standard formula:

A = P(1 + r/n)nt

  • A = Future value of the investment
  • P = Principal investment amount
  • r = Annual interest rate (decimal)
  • n = Number of times interest is compounded per year
  • t = Number of years

📈 What is Compound Interest?

Compound interest is the interest earned not only on your initial deposit (principal) but also on the interest accumulated over previous periods. This powerful financial concept allows your investments or savings to grow exponentially over time, making it more effective than simple interest.


Whether you're saving money, investing in a mutual fund, or planning for retirement, understanding how compound interest works is key to maximizing your returns.

🧮 How to Calculate Compound Interest?

Use the standard compound interest formula:

A = P (1 + r/n)nt

  • A = the future value of the investment/loan, including interest
  • P = the principal investment amount
  • r = the annual interest rate (in decimal form)
  • n = the number of times interest is compounded per year
  • t = the time the money is invested or borrowed for, in years

Example: If you invest $1,000 at 5% interest compounded annually for 5 years, your investment grows to more than $1,276 — thanks to compounding!
