Worked from the standard EMI formula. Your bank’s rate and fees will differ.
A car loan turns a big price into a monthly number, which is why it is easy to borrow more than you should. Before you look at variants, work out the EMI you can carry comfortably and let that decide the budget.
This guide explains how EMI is calculated, what moves it up or down, and the costs that do not appear in the EMI at all. You can try your own numbers on the EMI calculator on our home page.
Key takeaways
- A bigger down payment cuts both your EMI and the total interest.
- A longer tenure lowers the EMI but raises the interest you pay overall.
- Banks fund the on-road price differently, so check how much of it they will lend.
- Add insurance, fuel and servicing to the EMI to see the real monthly cost.
How EMI is calculated
Banks use a standard formula. EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate (yearly rate ÷ 12 ÷ 100) and n is the number of months.
For a loan of ₹8 lakh at 9% a year for 5 years (60 months), the EMI works out to about ₹16,600. Over five years you repay about ₹9.96 lakh, so the interest is about ₹1.96 lakh.
What changes your EMI
| Loan of ₹8 lakh at 9% | EMI | Total interest |
|---|---|---|
| 3 years | About ₹25,400 | About ₹1.16 lakh |
| 5 years | About ₹16,600 | About ₹1.96 lakh |
| 7 years | About ₹12,900 | About ₹2.81 lakh |
Stretching the loan from 5 to 7 years cuts the EMI by about ₹3,700 a month but adds about ₹85,000 in interest. A lower interest rate or a larger down payment saves money in every case.
The down payment works the same way. On a ₹10 lakh on-road price, paying ₹2 lakh down instead of ₹1 lakh means borrowing ₹8 lakh instead of ₹9 lakh. At 9% for five years, that is roughly ₹2,000 less every month and about ₹25,000 less interest over the loan.
Get a loan quote from your own bank before visiting the dealer. Dealer-arranged loans can be convenient, but a pre-approved offer gives you something to compare against.
How much car can you afford?
A common rule of thumb, often called 20/4/10, is: pay at least 20% as down payment, keep the loan to 4 years or less, and keep total car costs (EMI, fuel, insurance) under 10% of your monthly income. It is strict, and many buyers stretch it, but it is a useful starting point.
- Start from your income Decide the monthly amount you can spend on the car without cutting savings.
- Subtract running costs Take out fuel, insurance and servicing. What is left is your EMI limit.
- Work back to the loan Use the EMI calculator to find the loan that fits that EMI at your bank’s rate.
- Add the down payment Loan plus down payment is your maximum on-road budget.
Fixed or floating rate
Most car loans in India are fixed-rate, which means the EMI stays the same for the whole tenure. Some lenders offer floating-rate loans linked to an external benchmark, where the EMI or tenure can change when rates move. A fixed rate is easier to plan around. A floating rate can work out cheaper if rates fall, but you carry the risk if they rise.
Documents you will need
- PAN card and Aadhaar for identity and KYC.
- Income proof: recent salary slips and Form 16 for salaried buyers, or income-tax returns for the self-employed.
- Bank statements for the last few months.
- The dealer’s quotation or proforma invoice for the car.
Costs the EMI does not show
- Processing fees and charges: banks charge a processing fee, and some charge for foreclosure or part-payment. Read the sanction letter.
- Insurance renewal: own-damage cover must be renewed every year.
- Hypothecation: the bank’s name is on your RC until the loan is closed. Remove it from the RC after the last EMI.
A “zero down payment” or very low EMI offer usually means a longer tenure or extra charges. Compare the total amount you will repay, not only the monthly figure.
Questions buyers ask
Is a longer car loan better?
It lowers the EMI but increases total interest. Choose the shortest tenure whose EMI you can manage comfortably.
Can I prepay a car loan?
Usually yes, but check the bank’s foreclosure and part-payment charges in your loan agreement.
Does the loan cover the on-road price?
It depends on the bank. Some lend a share of the ex-showroom price, others of the on-road price. Ask before you book.
