How to calculate car loan EMI and the real cost

Updated 2026-11-13

Quick answer

A car loan EMI uses the same formula as any reducing-balance loan. For ₹8,00,000 at 9.5% over 5 years (60 months) the EMI is ₹16,801, and you repay ₹10,08,089, so the loan costs ₹2,08,089 in interest.

Steps

  1. Work out the amount to borrow: the on-road price minus your down payment. Here it is ₹8,00,000.
  2. Enter the yearly interest rate, 9.5%, and the tenure, 5 years, in the car loan calculator.
  3. Read the monthly EMI, ₹16,801, and the total interest, ₹2,08,089.
  4. Change the tenure to 3 and 7 years to compare, and keep the EMI that fits your monthly budget.
  5. Add the costs the EMI does not cover: insurance, fuel, servicing and any processing fee.

How tenure changes the cost

On ₹8,00,000 at 9.5%: a 3-year loan has an EMI of ₹25,626 and costs ₹1,22,549 in interest. A 5-year loan has an EMI of ₹16,801 and ₹2,08,089 of interest. A 7-year loan lowers the EMI to ₹13,075 but costs ₹2,98,316.

Going from 3 to 7 years cuts the monthly payment by about half, yet the interest more than doubles. A car also loses value quickly, so a very long loan can leave you owing more than the car is worth for longer.

What a bigger down payment does

Borrow ₹6,00,000 instead of ₹8,00,000 on the same terms and the EMI drops to ₹12,601 and the interest to ₹1,56,067. The ₹2,00,000 you pay up front saves about ₹52,000 of interest over the five years, besides lowering the EMI.

Check the rate type and the fees

Quotes are sometimes given as a flat rate, which is charged on the full amount for the whole tenure and costs much more than the same number quoted as a reducing rate. Ask which one you are being offered, and add the processing fee to the cost of the loan when you compare lenders.

Common questions

What tenure is best for a car loan?

Three to five years is common. A shorter loan costs less in interest, and you stop paying while the car still has good value.

Is a flat rate the same as a reducing rate?

No. A flat rate does not fall as you repay, so the same quoted number costs far more. Compare lenders on the reducing-balance rate.

Should I pay a larger down payment?

If you can, yes. It lowers the loan, the EMI and the total interest, and it reduces the chance of owing more than the car is worth.

Does the EMI include insurance?

No. The EMI repays the loan and its interest only. Insurance, registration and running costs are extra.
