Simple interest

- Interest₹500 (5%)
- Interest per year
- ₹500
- Interest per month
- ₹41.67
- Principal
- ₹10,000
- Total amount (principal + interest)

Simple interest is the same every year: ₹500. With compound interest you would also earn interest on the interest, so the total would be higher.
