EMI stands for equated monthly instalment. It is a fixed amount you pay each month to repay a financed purchase or loan, and each payment covers part of the principal and part of the interest.

How is EMI calculated?

EMI is calculated with the reducing-balance formula EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the financed amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the number of months.

Does a higher down payment reduce EMI?

Yes. A higher down payment reduces the financed amount, so both the monthly EMI and the total interest you pay become smaller.

Does a longer tenure reduce monthly EMI?

Yes. Spreading the same amount over more months lowers each monthly payment, although it keeps you paying for longer.

Does a longer tenure increase total interest?

When the interest rate is above 0%, yes. A longer tenure means interest is charged for more months, so the total interest paid is higher even though the monthly EMI is lower.

Can I calculate EMI with zero interest?

Yes. Enter 0 as the annual interest rate and the calculator shows a no-interest EMI, which is the financed amount divided equally across the tenure.

Does this calculator show actual Amazon or Flipkart EMI offers?

No. It is a mathematical estimation tool and does not retrieve live Amazon, Flipkart, bank, or card EMI offers. Check the checkout page or your bank for the exact terms that apply to you.

Does cashback reduce my EMI?

In this calculator, cashback you enter lowers the effective purchase price and therefore the financed amount. In real life, cashback is often credited later and your lender may calculate EMI on the amount charged, so confirm how your offer works.

How Does an EMI Calculator Work?

An EMI (equated monthly instalment) calculator splits the amount you finance into equal monthly payments that include both repayment and interest. This calculator uses the standard reducing-balance method, where interest each month is charged only on the balance you still owe.

Product price: The listed price of the item you plan to buy. It is the starting point for every other figure.
Down payment: The amount you pay upfront. It is not financed and does not attract interest, so a larger down payment means a smaller loan.
Financed amount: The effective purchase price minus your down payment. This is the principal on which the EMI and interest are calculated.
Annual interest rate: The yearly rate charged by the lender, entered as a percentage. A rate of 0% means a no-interest EMI.
Monthly interest rate: The annual rate divided by 12 and then by 100. For example, 12% a year is 1% a month (0.01).
Loan tenure: The number of months over which you repay. Common shopping EMI tenures range from 3 to 60 months.
Monthly EMI: The fixed amount you pay every month during the tenure, covering part of the principal and part of the interest.
Total interest: The extra money you pay for financing: the total of all EMIs minus the financed amount.
Total amount paid: Your down payment plus every EMI you pay. It equals the effective purchase price plus the total interest.

The EMI formula

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

Here P is the financed amount, r is the monthly interest rate, and n is the number of months. When the interest rate is 0%, the calculator simply divides the financed amount by the number of months.

Calculate the Real Cost of an Online Purchase

The price shown on a product page is rarely the full story. What you actually spend depends on several things that can push the cost up or down.

Coupons that reduce the price at checkout
Cashback that is credited back after you pay
Bank or card offers that give an instant or delayed discount
Shipping or delivery charges on the order
Interest charged when you pay through EMI
Processing fees and other charges added by a lender

The Additional Shopping Costs section in the calculator lets you enter these amounts yourself to see a more realistic effective price. DealTrackerProBot does not fill them in for you from this calculator: every value comes from what you type.
