EMI Calculator

Calculate equated monthly installment for home loans, car loans, personal loans and any loan type. View total interest, amortization schedule, and see how prepayment saves you money.

%/yr
Optional: Prepayment

"Reduce EMI" lowers your monthly payment. "Reduce Tenure" keeps the same EMI and shortens the loan period.

EMI Formula

EMI = P × r × (1+r)^n / [(1+r)^n − 1] Where: EMI = Equated Monthly Installment P = Principal loan amount r = Monthly interest rate (Annual Rate / 12 / 100) n = Total number of monthly installments Total Payment = EMI × n Total Interest = (EMI × n) − P With Prepayment: If reducing EMI: New EMI = (P - Prepayment) × r × (1+r)^n / [(1+r)^n − 1] If reducing tenure: Solve for new n where EMI stays the same Monthly Rate: r = Annual Rate / 12 / 100

EMI remains constant throughout the loan tenure because it is "equated" — the same amount every month. In the early months, the interest portion is larger; as you progress, the principal portion grows. This is the standard formula used by banks and NBFCs for computing monthly installments on home loans, car loans, personal loans, and education loans.

How to Use the EMI Calculator

1

Enter the Loan Amount

The total amount you wish to borrow from the lender. For home loans, this is the property price minus down payment. For car loans, it is typically the on-road price minus down payment.

2

Set the Interest Rate and Tenure

Enter the annual interest rate quoted by your lender. Then choose the loan tenure in months — common options range from 12 months to 360 months (30 years). Longer tenures mean lower EMI but more total interest.

3

Add Prepayment (Optional)

If you plan to make a lump sum prepayment, enter the amount and choose whether to reduce your EMI or shorten the loan tenure. The calculator shows how much you save in interest and time.

Example Calculation

50,00,000 at 8.5% for 3 years (36 months)

Given:

  • Principal = 50,00,000
  • Annual Rate = 8.5% → Monthly Rate = 0.7083%
  • Tenure = 3 years → 36 monthly installments

Step 1: Calculate monthly rate

r = 8.5 / 12 / 100 = 0.007083

Step 2: Apply EMI formula

EMI = 50,00,000 × 0.007083 × (1.007083)^36 / [(1.007083)^36 − 1]
= 50,00,000 × 0.007083 × 1.2901 / [1.2901 − 1]
= 50,00,00 × 0.009139 / 0.2901
= 1,57,587.04

Monthly EMI: 1,57,587.04

Total Payment: 56,73,133.44

Total Interest: 6,73,133.44

Interest-to-Principal: 13.46%

Understanding the Results

Monthly EMI

The fixed amount you pay every month. It covers both principal and interest. Because it is "equated," the amount stays the same every month, making budgeting predictable. The interest-to-principal ratio tells you how much of each payment goes toward interest versus actually reducing your debt.

Total Interest

The extra amount you pay above the principal — the cost of borrowing. On long-tenure loans, total interest can exceed the principal amount. Shorter tenures and lower rates dramatically reduce this cost.

Prepayment Savings

Making a lump sum prepayment directly reduces the principal, saving on interest and either lowering your EMI or shortening your loan. Even small prepayments early in the loan save disproportionately more because they reduce the principal base for all future interest calculations.

Important Note

This calculator uses the reducing balance method (standard for EMI). Actual EMI may vary slightly due to processing fees, rounding methods, and day-count conventions used by different lenders. Always confirm with your bank for the exact EMI figure.

Key Definitions

EMI

Equated Monthly Installment — the fixed monthly payment made to repay a loan over a set period. Each payment includes both principal and interest.

Principal

The original sum borrowed from the lender. EMI gradually reduces this balance to zero over the loan tenure.

Reducing Balance Method

The standard EMI calculation method. Interest is computed on the outstanding balance each month, so as you pay down principal, interest charges decrease over time.

Flat Rate Method

Interest is computed on the original principal throughout the tenure, regardless of payments made. Results in higher total interest. Rarely used for standard loans.

Prepayment

A lump sum payment made toward the loan principal, either to reduce EMI or shorten the loan tenure. Saves significant interest when made early in the loan.

Tenure

The duration of the loan in months. Common home loan tenures are 120-360 months. Shorter tenures have higher EMI but less total interest.

Frequently Asked Questions

EMI stands for Equated Monthly Installment. It is the fixed monthly payment you make to repay a loan over a fixed period. Each EMI payment includes both principal and interest components, calculated so the loan is fully repaid by the end of the tenure. EMI remains the same every month, making budgeting straightforward.
EMI is calculated using the formula: EMI = P × r × (1+r)^n / [(1+r)^n − 1], where P is the loan amount, r is the monthly interest rate (annual rate / 12 / 100), and n is the total number of monthly installments. This is the reducing balance method, which is the standard used by banks and NBFCs. The flat rate method, which charges interest on the original principal throughout, is rarely used for standard loans.
Yes, but the effect depends on the prepayment mode. With "Reduce EMI" mode, the EMI decreases while the tenure stays the same. With "Reduce Tenure" mode, the EMI stays the same but the loan finishes earlier. Reducing tenure generally saves more total interest because the principal reduces faster. Most lenders allow you to choose which mode to apply.
Financial experts recommend keeping total EMIs under 40-50% of your monthly income. For example, if your monthly income is 1,00,000, total EMIs should ideally stay below 40,000-50,000. Banks typically approve loans where EMI does not exceed 50-55% of income. Exceeding this makes approval unlikely and strains your finances.
Yes. The same EMI formula works for all fixed-rate loan types — home loans, car loans, personal loans, education loans, business loans, two-wheeler loans, gold loans, and any loan with fixed monthly installments. The only input that changes is the loan amount, interest rate, and tenure. Adjustable-rate loans require a more complex calculation since the rate changes periodically.
