💡 What is Simple Interest?
Simple Interest is the easiest way to calculate interest on a principal amount. The interest is calculated only on the original sum (principal) for the entire period of the loan or investment, without considering any interest that accumulates on previously earned interest.
Simple Interest = (P × R × T) / 100
Where: Simple Interest, P = Principal, R = Rate of Interest (% per annum), T = Time (years)
- Easy to calculate and understand
- Commonly used for short-term loans, car loans, and some savings accounts
- Interest does not compound over time
🔄 What is Compound Interest?
Compound Interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. This means you earn "interest on interest," which helps your money grow faster over time.
Compound Interest = P × [ (1 + R/100)T - 1 ]
Where: Compound Interest, P = Principal, R = Rate of Interest (% per annum), T = Time (years)
- Interest is calculated on both principal and accumulated interest
- Common for fixed deposits, recurring deposits, and long-term investments
- Leads to faster wealth growth due to compounding effect

⚖️ Difference Between Simple Interest and Compound Interest
| Feature | Simple Interest | Compound Interest |
|---|---|---|
| Interest Calculation | Only on principal | On principal + accumulated interest |
| Growth Rate | Slower | Faster (due to compounding) |
| Common Uses | Short-term loans, car loans | FDs, RDs, long-term investments |
| Formula | Simple Interest = (P × R × T) / 100 | Compound Interest = P × [ (1 + R/100)T - 1 ] |
🧮 Examples of Simple Interest and Compound Interest
Simple Interest = (10,000 × 10 × 3) / 100 = ₹3,000
Total amount after 3 years = ₹13,000
Compound Interest = 10,000 × [ (1 + 10/100)3 - 1 ] = 10,000 × (1.331 - 1) = ₹3,310
Total amount after 3 years = ₹13,310
