How the car loan EMI is calculated
You borrow the on-road price minus the down payment. Interest each month is the opening balance times the yearly rate divided by 12. The EMI is rounded to the nearest rupee. The last instalment clears whatever principal is left. This is the same reducing-balance engine as the EMI calculator.
The 9.5% rate is a starting point. Use the rate on your sanction letter. It is not a bank’s offer. This page does not add a processing fee or loan insurance.
On-road price and what you borrow
The on-road price is what you pay to drive the car away. It includes tax, insurance, and registration. The ex-showroom price is lower, and a loan on that figure understates the amount you need. Type the on-road price from the quotation. The down payment can be a percent of that price or a rupee amount. The loan is the rest.
The 20/4/10 check, on a ₹10 lakh car
20/4/10 is a planning check, not a regulation. It asks for at least 20% down, a tenure of 4 years or less, and an EMI within 10% of monthly take-home pay.
An on-road price of ₹10,00,000, with 20% down, means you pay ₹2,00,000 now and borrow ₹8,00,000. At 9.5% for 5 years, the EMI is ₹16,801. Interest is ₹2,08,097. You repay ₹10,08,097. The car costs ₹12,08,097 once the down payment is included.
The 20% down payment passes. Five years fails the 4-year check. At a take-home pay of ₹1,00,000, the EMI is 16.8% of pay, so the 10% check fails too. The on-road price that fits all three parts, at this pay and this rate, is ₹4,97,549. That uses a 4-year loan and a 20% down payment.
A longer tenure costs more interest
The same ₹8,00,000 at 9.5% for 7 years has an EMI of ₹13,075 and interest of ₹2,98,322. That is ₹90,225 more interest than the 5-year loan, for a lower monthly payment. A new-car loan often runs up to 7 years. A used-car loan is often shorter. Those are typical tenures, not a cap. The slider stops at 84 months.
Take-home pay comes from the in-hand salary calculator. An unsecured loan is the personal loan EMI calculator. Fuel for the car you are pricing is on the petrol and diesel page. More loan tools are on loans and home.
