What is the Difference Between Compound Interest and Simple Interest?

🆚 Go to Comparative Table 🆚

The main difference between compound interest and simple interest lies in how the interest is calculated and applied. Here are the key differences:

  1. Calculation: Simple interest is calculated on the principal, or original, amount of a loan, while compound interest is calculated on the principal amount and the accumulated interest of previous periods.
  2. Accumulation: Simple interest accumulates only on the principal balance, whereas compound interest accrues to both the principal balance and the accumulated interest.
  3. Frequency: Simple interest is typically calculated annually, whereas compound interest can be calculated at various frequencies, including daily, monthly, quarterly, or annually.
  4. Interest Rates: Simple interest has fixed interest rates, while compound interest rates can vary depending on the institution.
  5. Benefits: Compound interest is more favorable for investors, as it allows for faster wealth accumulation, while simple interest is more advantageous for borrowers, as they don't need to pay interest on the already accumulated interest.

In summary, simple interest is based only on the principal amount, and it is calculated annually, making it more suitable for borrowers. On the other hand, compound interest is based on both the principal and accumulated interest, and it can be calculated at various frequencies, making it more favorable for investors and wealth accumulation.

    Here is a table comparing the differences between compound interest and simple interest:

    Feature Simple Interest Compound Interest
    Interest Calculation Calculated only on the principal amount Calculated on the principal amount and accumulated interest
    Growth Over Time Grows at a steady rate Grows at an increasing rate, especially over long periods
    Best Use Commonly used for short-term loans or investments Better for long-term investments and savings accounts
    Formula A = P (1 + rt) A = P (1 + r/n)^(nt) - 1
    where: A = total amount, P = principal, r = interest rate, t = time in years where: A = total amount, P = principal, r = interest rate, n = number of compounding periods per year, t = time in years

    Simple interest is calculated based on the principal balance only, while compound interest takes into account both the principal balance and any interest that has already been earned. Compound interest grows at a faster rate than simple interest, especially over long periods. Simple interest is commonly used for short-term loans or investments, while compound interest is better for long-term investments and savings accounts.
