Introduction
Interest is the cost of borrowing Money or the reward for lending it. Simple Interest (SI) is calculated only on the principal amount, while Compound Interest (CI) is calculated on the principal and the accumulated interest over time. This fundamental difference leads to varying outcomes, especially over longer periods.

| Feature | Simple Interest (SI) | Compound Interest (CI) |
|---|
| Interest Calculation Basis | Principal Only | Principal + Accumulated Interest |
| Interest Amount (Year 1) | Rs. 520 | Rs. 520 |
| Interest Amount (Year 2) | Rs. 520 | Rs. 540.80 |

| Total Amount (Principal + Interest) | Rs. 14,560 | Rs. 14,623.23 |
Advantages and Disadvantages
| Type of Interest | Advantages | Disadvantages |
|---|
| Simple Interest | – Easier to calculate | – Lower returns compared to CI over time |
| Compound Interest | – Higher returns due to the compounding effect, especially beneficial for long-term investments | – Can be harder to understand due to the accumulation of interest on interest |
| – Predictable interest payments | – The total amount to be repaid can be significantly higher than the original principal |
Similarities
- Both SI and CI involve calculating interest on a principal amount.
- The interest rate and the principal amount are the same for both in the initial year.
FAQs on CI vs. SI (Rs. 13,000 at 4% per annum for 3 years)
- What is the formula for calculating SI?
SI = (Principal * Rate * Time) / 100 - What is the formula for calculating CI?
CI = Principal * [(1 + Rate/100)^Time – 1] - Which type of interest is better for borrowers?
SI is generally better for borrowers due to lower overall interest payments. - Which type of interest is better for lenders or investors?
CI is better for lenders and investors due to higher returns over time. - Does the frequency of compounding affect CI?
Yes, the more frequently interest is compounded (e.g., quarterly, monthly), the higher the overall return.
Conclusion
Understanding the difference between Compound Interest and Simple Interest is crucial for making informed financial decisions. Whether you’re borrowing or investing, knowing how interest is calculated can significantly impact your financial outcomes.
