EMI stands for Equated Monthly Installment. It is the fixed monthly payment made to a lender to repay a loan over a set period. Each EMI includes both a principal component and an interest component, ensuring the loan is fully repaid by the end of the tenure.

How is EMI calculated?

EMI is calculated using the formula: EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the total number of monthly installments. This formula ensures each payment covers the accrued interest plus a portion of the outstanding principal.

Can I prepay my loan to reduce EMI?

Yes, most lenders allow part-prepayment of loans. When you make a prepayment, the outstanding principal reduces, which can either lower your EMI amount or shorten the loan tenure. Some lenders may charge a prepayment penalty, so check your loan agreement before making prepayments.

What happens if interest rates change?

If you have a floating-rate loan, your EMI or tenure may change when interest rates are revised by the lender. An increase in rates typically raises your EMI or extends the tenure, while a decrease lowers the EMI or shortens the tenure. Fixed-rate loans are not affected by rate changes during the loan period.

What Is EMI and How Is It Calculated?

EMI stands for Equated Monthly Installment. It is the fixed amount you pay every month to repay a loan over a defined period. EMIs include both the principal repayment and the interest charged by the lender, ensuring the loan is fully paid off by the end of the tenure. Home loans, car loans, personal loans, and education loans all typically use EMI-based repayment structures.

The EMI Formula

The standard EMI formula is: EMI = P × r × (1 + r)ⁿ / ((1 + r)ⁿ − 1), where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12 and then by 100), and n is the total number of monthly installments. This formula ensures each payment covers the interest accrued for that month plus a portion of the outstanding principal.

How to Use This Calculator

Enter your loan amount in Indian Rupees, the annual interest rate offered by your bank, and the repayment tenure in years or months. The calculator instantly displays your monthly EMI, the total interest you will pay over the loan period, and the overall payment amount. The donut chart visually breaks down how much of your total outflow goes toward the principal versus interest, helping you compare different loan offers and choose the one that minimizes your interest burden.

A lower interest rate or a shorter tenure reduces total interest paid, while a longer tenure lowers the monthly EMI but increases the total cost. Use this calculator to experiment with different scenarios before committing to a loan, so you can plan your finances with confidence.

Formula

EMI = P × r × (1 + r)ⁿ / [(1 + r)ⁿ − 1]

Where:

EMI = Equated Monthly Instalment
P = principal loan amount
r = monthly interest rate (annual rate ÷ 12)
n = total number of monthly instalments (tenure in months)

Example Calculation

Scenario: ₹10,00,000 home loan at 8.5% annual interest for 20 years

Step 1: Monthly rate r = 8.5% ÷ 12 = 0.007083
Step 2: Total instalments n = 20 × 12 = 240
Step 3: EMI = ₹10,00,000 × 0.007083 × (1.007083)²⁴⁰ / [(1.007083)²⁴⁰ − 1]
Result: EMI = ₹8,678 | Total interest paid = ₹10,82,720
