EMI calculator

What is EMI?

EMI stands for Equated Monthly Installment, the fixed amount you pay every month to repay a loan, covering both principal and interest, until the loan is fully paid off. It's the standard way home loans, car loans, and personal loans are structured, since a fixed, predictable monthly payment makes budgeting straightforward for borrowers.

This calculator finds your exact EMI from the loan amount, interest rate, and tenure, and shows the full breakdown of how much of your total repayment goes to interest versus principal.

How to use it

1. Enter the loan amount, the total principal you're borrowing (use the slider or type an exact number).
2. Enter the annual interest rate your lender is offering.
3. Enter the loan tenure, switching between years and months depending on what's easier.
4. Click Calculate EMI to see your monthly payment, total interest, and total repayment.
5. Click View month-by-month schedule for the full breakdown of every payment across the loan.

The EMI formula

EMI is calculated using the standard formula: EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1), where P is the principal loan amount, r is the monthly interest rate (your annual rate divided by 12, then by 100), and n is the total number of monthly payments (your tenure in months).

This formula ensures that every EMI payment is exactly the same amount for the life of the loan, even though the mix of principal and interest within each payment changes over time.

Why the interest-to-principal ratio shifts over time

In the early months of a loan, most of your EMI goes toward interest, since interest is calculated on the full outstanding balance, which is at its highest right at the start. As the balance gradually shrinks with each payment, less interest accrues, so a growing share of each fixed EMI goes toward principal instead. This is why paying off a loan early, or making extra principal payments in the early years, saves significantly more in total interest than doing so later in the loan term.

How loan amount, rate, and tenure each affect your EMI

• Loan amount - a larger principal directly increases your EMI, roughly proportionally
• Interest rate - a higher rate increases both your EMI and the total interest you'll pay over the loan's life
• Tenure - a longer tenure lowers your monthly EMI, making it easier to afford month-to-month, but increases the total interest paid overall since the loan accrues interest for a longer period

Common uses

• Estimating your monthly payment before applying for a home, car, or personal loan
• Comparing how different interest rates or tenures change your monthly payment
• Checking whether a proposed EMI fits comfortably within your monthly budget
• Understanding exactly how much of your total repayment is interest versus principal
• Planning for early repayment by seeing how the principal-interest split changes over the loan term

Frequently asked questions

Does a lower EMI always mean a better deal?

Not necessarily. A lower EMI often comes from a longer tenure, which usually means paying more total interest over the life of the loan, even though each individual payment is smaller. It's worth comparing total interest paid, not just the monthly figure, when evaluating loan options.

Does this calculator include processing fees or other charges?

No, this covers principal and interest only, based on the standard EMI formula. Many lenders charge separate processing fees, insurance premiums, or other charges, check with your lender for the complete cost of the loan.

Can I use this for a loan that isn't paid monthly?

This calculator is built specifically for standard monthly EMI loans. For loans with a different payment frequency (weekly, quarterly, and so on) or non-standard structures, the Loan Calculator offers more flexible compounding and payment frequency options.

Why does my bank's EMI figure differ slightly from this calculator?

Small differences can come from rounding conventions, how the lender calculates the first partial period, or additional fees folded into their figure. This calculator uses the standard, widely-used EMI formula for principal and interest.
