Compound Interest Calculator

Compound Interest Calculator

Our Compound Interest Calculator helps you estimate the growth of your savings or investments by factoring in regular contributions, interest rates, and compounding frequency. Whether you're planning for retirement, saving for a big purchase, or just curious about how your money grows over time, this tool simplifies financial planning for everyone.

What is Compound Interest?

Compound interest is the process of earning interest on both your original investment and the accumulated interest over previous periods. This compounding effect allows your savings to grow faster over time compared to simple interest, which is only calculated on the principal amount.

It’s often referred to as “interest on interest,” and is considered one of the most powerful tools in personal finance and investing.

How Compound Interest Works

Compound interest is calculated based on a standard formula:

A = P(1 + r/n)nt

Where:

• A = Future value of the investment
• P = Principal (starting amount)
• r = Annual interest rate
• n = Number of times the interest compounds per year
• t = Time in years

Our calculator automates this process and provides instant results. Just enter your details and get accurate projections.

3. Choose your interest rate (annual percentage).
