What is Compound Interest?

Compound interest is the interest earned on both your original investment (principal) and the interest accumulated over previous periods. Unlike simple interest, compound interest allows your investment to grow at an accelerating rate because each interest payment earns additional interest.

This is why compound interest is often called the “eighth wonder of the world” and is one of the most powerful concepts in long-term investing.

• Interest is earned on both principal and accumulated interest.
• Creates exponential wealth growth over time.
• Ideal for long-term investments.
• Works best when investments remain untouched.
• Suitable for retirement planning and wealth creation.

How Does a Compound Interest Calculator Work?

A Compound Interest Calculator estimates the future value of your investment by considering your initial investment, annual interest rate, investment duration, and compounding frequency.

Simply enter:

• Initial Investment Amount
• Annual Interest Rate (%)
• Investment Duration (Years)
• Compounding Frequency (Monthly, Quarterly, Half-Yearly, or Yearly)

The calculator instantly displays:

• Total Investment
• Total Interest Earned
• Estimated Maturity Value

Compound Interest Formula

Where:

• FV = Future Value (Maturity Amount)
• PV = Principal Investment
• r = Interest Rate per Compounding Period
• n = Total Number of Compounding Periods

The formula calculates how your investment grows over time by adding earned interest back to the principal at every compounding period.
