How to Calculate Loan EMI (With Formula & Example)

Guides · Finance · Updated 2026

EMI stands for Equated Monthly Instalment — the fixed amount you pay every month to repay a loan. Whether it's a home, car or personal loan, understanding how EMI is calculated helps you plan your budget and compare loan offers with confidence.

The EMI formula

EMI is calculated using this standard formula:

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

Where:

P = principal (the loan amount)
r = monthly interest rate = annual rate ÷ 12 ÷ 100
n = number of monthly instalments (tenure in months)

A worked example

Suppose you borrow ₹5,00,000 at 9% annual interest for 5 years (60 months):

Monthly rate r = 9 ÷ 12 ÷ 100 = 0.0075
Applying the formula gives an EMI of about ₹10,379 per month.
Total payment over 60 months ≈ ₹6,22,751.
Total interest paid ≈ ₹1,22,751.

Step-by-step: calculate your EMI

Open the EMI Calculator.
Enter the loan amount, annual interest rate and tenure in months.
Click Calculate to see your EMI, total interest and total payment.

💡 Tip: A longer tenure lowers your monthly EMI but increases the total interest you pay. Try different tenures to find the right balance.

How to reduce your EMI

Make a larger down payment to reduce the principal.
Negotiate a lower interest rate or compare lenders.
Choose a longer tenure for lower monthly payments (but more total interest).
Make part-prepayments when you can to cut the outstanding balance.

Frequently Asked Questions

What exactly is EMI?

EMI is the fixed monthly amount you pay to repay a loan. Each instalment covers part interest and part principal, and the loan is fully cleared by the final EMI.

Does the calculator include processing fees?

No. It calculates EMI purely from the principal, interest rate and tenure. Lenders may add one-time fees such as processing or insurance charges separately.

Does prepayment reduce my EMI or my tenure?

Usually you can choose. Reducing tenure saves the most interest, while reducing EMI eases your monthly budget. Ask your lender which option they apply.

Can I use it for any currency?

Yes. The EMI formula is the same everywhere — just enter the amount in your currency. Only the symbol shown differs.

Why do I pay more interest early in the loan?

Interest is charged on the outstanding balance, which is highest at the start. As you repay, the balance falls, so later EMIs contain more principal and less interest.
