Car EMI vs Salary: Calculate Your Safe Budget

01"I earn ₹80,000 a month — how expensive a car can I afford?"

With Dhanteras on 6 November 2026 and festive offers everywhere, many first-time buyers are asking this question right now. The dealer will usually answer a different one: "what EMI can you pay?" — and then offer a longer loan to make a bigger car fit. That is how a car that looked affordable in the showroom ends up squeezing your savings for seven years.

The safer way is to start from your salary, not from the car. Decide how much of your take-home pay — the salary that actually reaches your bank account after tax and provident fund — can go to a car, then work backwards to the loan and the price.

02The 20/4/10 rule, adapted for India: 20/4/15

A popular rule of thumb for car buying is 20/4/10: put down at least 20 %, borrow for no more than 4 years, and keep car costs within 10 % of your income. It was written for countries where cars are cheap relative to salaries. In India a basic car costs more months of salary, so the 10 % limit would rule out a car for most buyers. A workable version for Indian salaries is 20/4/15, plus one all-in check:

1. 20 % down. Pay at least 20 % of the on-road price — the ex-showroom price plus road tax (RTO), registration, first-year insurance and accessories — from your savings. Lenders often fund 80–90 %, but a bigger down payment means a smaller loan and less interest.
2. 4 years. Repay the loan in 4 years, 5 at most. A car loses value quickly; a long loan can leave you owing more than the car is worth.
3. 15 % EMI. Keep the EMI within 15 % of your monthly take-home pay. The Car Loan Calculator flags an EMI above 15 % as on the high side.
4. 30 % all-in. Keep the EMI plus fuel, insurance, servicing and parking within 30 % of take-home pay — the share the 50/30/20 budget gives to all your "wants". Above that, the car eats into your savings.

To turn a safe EMI into a loan amount, the Loan Capacity Calculator runs the EMI formula backwards:

Then the car you can afford is the loan plus your 20 % down payment. Because the loan is 80 % of the price, on-road price = loan ÷ 0.8.

03How much car can you afford on your salary?

Here is the rule applied to three take-home salaries, with an illustrative car-loan rate of 9.5 % a year. Car-loan rates differ by lender, your credit score and the car, so use the rate in your own loan offer.

How to read it. On ₹80,000 a month, 15 % is ₹12,000. At 9.5 % for 48 months, ₹12,000 a month repays a loan of ₹4,77,647. That is 80 % of the price, so the car can cost ₹4,77,647 ÷ 0.8 = ₹5,97,059 on-road, of which you pay ₹1,19,412 upfront. Stretching the loan to 5 years raises the budget to ₹7,14,223 — but you pay interest for a year longer.

Here the on-road price goes in as the ex-showroom price with road tax set to 0. For a real quote, enter the ex-showroom price, your state's road-tax percentage, insurance and accessories instead. Put your own take-home pay in "Your Monthly Take-home" (under advanced options) to see the EMI as a share of it.

04The EMI is only part of it: the total monthly cost of a car

A car has running costs from the first day: fuel, insurance renewals, servicing, tyres, parking, FASTag and tolls. For a small car they can add 75 % or more on top of the EMI. These are the assumptions for the ₹5.97 lakh car in our ₹80,000 example:

Fuel is from the Trip Fuel Cost Calculator: 1,000 km at 17 km a litre needs 58.8 litres, which at the Delhi price of ₹102.12 a litre (PPAC, as of October 2026) is ₹6,007. Use your own monthly distance, your car's real mileage and your city's fuel price. Petrol prices are held flat here; if they rise, so does this line.

05What if you stretch to a ₹10 lakh car?

Say the same ₹80,000 earner falls for a car with an ex-showroom price of ₹10 lakh. With 10 % road tax, ₹40,000 insurance and ₹15,000 of accessories, it costs ₹11,55,000 on-road. A 20 % down payment of ₹2,31,000 leaves a loan of ₹9,24,000. The dealer then offers a longer tenure to bring the EMI down:

The all-in cost adds ₹12,294 a month of running costs for the bigger car: petrol for 1,000 km at 14 km a litre (₹7,294), insurance renewal of ₹30,000 a year (₹2,500), servicing and tyres of ₹12,000 a year (₹1,000) and ₹1,500 for parking, FASTag and tolls.

Now change the tenure to 7 years. The EMI falls to ₹15,102, but total interest rises to ₹3,44,554 — ₹1,54,293 more than the 4-year loan — and you are still paying for the car in its seventh year, when it may be worth less than half its price.

06What's changed in 2026 for car loans

• Loan rates turned up. The RBI raised the policy repo rate by 0.25 % to 5.50 % on 7 October 2026, its first increase since February 2023, and changed its stance to "calibrated tightening". There is no single official car-loan rate: each lender sets its own, often linked to the repo rate or its MCLR. In our ₹80,000 example, a rate 0.25 % higher (9.75 % instead of 9.5 %) cuts the loan a ₹12,000 EMI supports from ₹4,77,647 to ₹4,75,385 — small, but check a floating-rate offer for how often it resets.
• Compare the APR, not the headline rate. Since October 2024 lenders must give you a Key Facts Statement (KFS) before you sign a retail loan. It shows the annual percentage rate (APR) — the yearly cost including the processing fee and other charges — and the repayment schedule. Festive "low rate" or "zero down" offers are easiest to compare on their APR.
• Running costs are rising. Retail inflation was 5.54 % in September 2026, up from 4.83 % in August (MoSPI, provisional). Petrol costs ₹102.12 a litre in Delhi (PPAC, as of October 2026) after the price increases of May 2026. Build some room into the 30 % all-in limit for fuel and insurance to cost more each year.
• GST on cars, since 22 September 2025: 18 % for small cars (up to 4 metres long, with an engine up to 1,200 cc for petrol, CNG or hybrid, or 1,500 cc for diesel), 40 % for larger cars, and 5 % for electric cars, with no compensation cess (GST Council and PIB, as of October 2026). The ex-showroom price already includes GST, so you don't add it again.

07Your next step

1. Find your monthly take-home pay on your payslip, or work it out from your CTC with the Salary Calculator.
2. Take 15 % of it as your safe EMI and put that into the Loan Capacity Calculator with your loan offer's rate and a 4-year tenure to see the loan it supports. Divide by 0.8 for your on-road car budget.
3. Put each car's on-road quote into the Car Loan Calculator with your down payment and take-home pay, and compare the EMI, total interest and what the car really costs you.
4. Estimate fuel with the Trip Fuel Cost Calculator and check the all-in monthly cost against your budget in the Budget Planner.
