Understand how EMI (Equated Monthly Installment) is calculated, what factors affect it, and how to use our free EMI calculator to plan your loan repayments.
Taking a loan? The most important number you need to know is your EMI — the fixed monthly amount you'll pay until the loan is fully repaid. Here's how it's calculated.
The EMI Formula
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1)
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Loan tenure in months
Example Calculation
Home loan of ₹50 lakhs at 8.5% for 20 years: r = 8.5 / 12 / 100 = 0.00708, n = 240 EMI ≈ ₹43,391/month Total amount paid ≈ ₹1.04 crores (₹54 lakhs as interest)
Factors That Affect Your EMI
- Principal: Higher loan = higher EMI (obviously)
- Interest rate: Even 0.5% difference matters hugely over 20 years
- Tenure: Longer tenure = lower EMI but far more interest paid
- Processing fees: These don't change EMI but increase total cost
