What Is Compound Interest?

Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, where interest is calculated only on the principal amount, compound interest helps your money grow faster over time.

In simple terms:

  • You earn interest on your investment
  • That interest gets added to your principal
  • In the next period, interest is calculated on the new total

This “interest on interest” effect makes compound interest one of the most powerful concepts in finance.

Example of Compound Interest Calculation

Let’s understand how this tool works with a real-life example.

Scenario:

  • Principal Amount: $5,000
  • Annual Interest Rate: 6%
  • Time Period: 10 years
  • Compounding Frequency: Monthly

Result:

  • Final Amount: Higher than simple interest due to monthly compounding
  • Total Interest: Shows how much profit you earned over 10 years

This example clearly demonstrates how frequent compounding significantly increases your returns over time.


How Compounding Frequency Affects Your Investment

Compounding frequency determines how often interest is added to your principal. The more frequently interest is compounded, the higher your final amount will be.

Comparison:

  • Yearly compounding grows slower
  • Monthly compounding produces higher returns
  • Quarterly and half-yearly fall in between

Choosing the right compounding frequency can make a noticeable difference, especially for long-term investments.
