How to Calculate Loan EMI in India
EMI stands for Equated Monthly Instalment — the fixed amount you pay your lender every month to repay a loan. Each EMI consists of two parts: a portion that goes toward repaying the principal (original loan amount) and a portion that covers the interest charged by the bank.
EMI Formula
The standard formula used by all banks and financial institutions to calculate EMI is:
Where:
P = Principal loan amount
r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
n = Loan tenure in months
For example, for a ₹25 lakh home loan at 8.5% for 20 years: r = 8.5/12/100 = 0.00708, n = 240. The EMI works out to approximately ₹21,699 per month.
Types of Loans and Typical Interest Rates (2025)
| Loan Type | Typical Rate (2025) | Max Tenure |
|---|---|---|
| Home Loan | 8.5% – 10.5% | 30 years |
| Car Loan | 8.7% – 12.5% | 7 years |
| Personal Loan | 10.5% – 18% | 5 years |
| Education Loan | 8.5% – 14% | 15 years |
How to Reduce Your EMI
- Larger down payment: Pay more upfront to reduce the principal and thus the EMI.
- Longer tenure: Spreading repayment over more months reduces monthly EMI — but increases total interest paid.
- Balance transfer: If you find a lower interest rate elsewhere, a loan balance transfer can significantly reduce EMI.
- Part prepayment: Making lump-sum payments toward principal reduces your outstanding balance and EMI.
- Negotiate rate: A good CIBIL score (750+) gives you leverage to negotiate a lower interest rate with your bank.
What is an Amortization Schedule?
An amortization table shows the month-by-month breakdown of every EMI payment — exactly how much goes to principal and how much to interest. In early months, the interest component is high. As the loan matures, more of each EMI goes toward principal repayment. This is why prepaying a loan early in its tenure saves the most interest.
