How to Calculate EMI: Complete Formula + Step-by-Step Examples
What is EMI (Equated Monthly Installment)?
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 is calculated based on three factors:
- Principal Amount (P): The original loan amount you borrowed
- Interest Rate (R): Annual interest rate (in percentage)
- Loan Tenure (N): Total time to repay the loan (in months)
Understanding EMI helps you plan your finances better and choose loans with better terms. Most Indians use EMI to buy homes, cars, and handle personal expenses.
EMI Formula Explained
The mathematical formula to calculate EMI is:
EMI = [P × r × (1+r)^n] / [(1+r)^n – 1]
Where:
- P = Loan Principal (amount borrowed)
- r = Monthly Interest Rate (annual rate ÷ 12 ÷ 100)
- n = Number of Months (tenure in years × 12)
This formula ensures you pay equal installments every month, making budgeting easier.
Step-by-Step EMI Calculation
Example: Home Loan of ₹25 Lakhs at 8% for 20 years
- Principal (P): ₹25,00,000
- Annual Interest Rate: 8%
- Monthly Interest Rate (r): 8 ÷ 12 ÷ 100 = 0.00667
- Tenure: 20 years = 240 months (n)
Calculation:
EMI = [25,00,000 × 0.00667 × (1.00667)^240] / [(1.00667)^240 – 1]
EMI = [25,00,000 × 0.00667 × 4.7193] / [4.7193 – 1]
EMI = [78,495] / [3.7193]
EMI ≈ ₹21,096 per month
Total amount paid over 20 years: ₹21,096 × 240 = ₹50,63,040
Total interest paid: ₹50,63,040 - ₹25,00,000 = ₹25,63,040

Common EMI Mistakes to Avoid
Mistake 1: Ignoring Processing Fees
Banks charge 0.5-2% processing fees upfront. This reduces your actual loan amount but increases effective interest rate.
Mistake 2: Not Comparing Interest Rates
A difference of 0.5% in interest rate can save/cost lakhs of rupees over the loan tenure. Always compare rates from multiple banks.
Mistake 3: Choosing Wrong Tenure
Longer tenure = lower EMI but higher total interest. Shorter tenure = higher EMI but lower total interest. Choose wisely based on affordability and interest savings goals.
