How to Calculate EMI? Formula & Examples
Published on January 15, 2025 | 5 min read
What is EMI?
EMI (Equated Monthly Installment) is the fixed amount you pay every month to repay a loan. Whether it's a home loan, car loan, or personal loan, EMI divides the total loan amount into equal monthly payments spread over the loan tenure.
EMI Formula
The mathematical formula to calculate EMI is:
EMI = P × r × (1 + r)^n / ((1 + r)^n - 1) Where: P = Principal loan amount (₹) r = Monthly interest rate (annual rate / 12 / 100) n = Total number of months (tenure in years × 12)
Step-by-Step EMI Calculation Example
Loan Details:
- Principal (P) = ₹50,00,000 (Home Loan)
- Annual Rate (R) = 8% per annum
- Tenure = 20 years
Calculation:
- Monthly Rate (r) = 8 / 12 / 100 = 0.00667
- Total Months (n) = 20 × 12 = 240
- EMI = 50,00,000 × 0.00667 × (1.00667)^240 / ((1.00667)^240 - 1)
- EMI = ₹41,322 (approximately)
How Interest Affects EMI
Higher interest rates = higher EMI. Here's a quick comparison:
| Interest Rate | EMI (₹50L, 20yr) |
|---|---|
| 7% | ₹38,928 |
| 8% | ₹41,322 |
| 9% | ₹43,862 |
| 10% | ₹46,578 |
Tips to Reduce EMI
- Increase Down Payment: Pay more upfront to reduce loan amount
- Extend Loan Tenure: Longer tenure = smaller EMI (but more total interest)
- Negotiate Interest Rate: Shop with multiple banks for better rates
- Improve Credit Score: Better score = lower interest rates
- Make Prepayments: Pay extra when possible to reduce principal faster
EMI vs Total Interest Paid
Remember: You pay both principal and interest in each EMI. As the months pass, more EMI goes toward principal and less toward interest.
Example (₹50L at 8% for 20 years):
- Total EMI Paid = ₹41,322 × 240 = ₹99,17,280
- Total Interest = ₹99,17,280 - ₹50,00,000 = ₹49,17,280
