The most expensive car loan mistake is to look only at the monthly EMI. A low EMI can hide a long tenure, high fees and a total cost far above the car's worth. Other common errors include skipping the Key Fact Statement, buying add-ons you did not need, and not planning for insurance and running costs. This guide lists ten mistakes and five myths, with a fix for each.

Ten mistakes and how to avoid them
Ten car loan mistakes
| Mistake | Why it costs you | What to do instead |
|---|---|---|
| Judging by EMI alone | A low EMI can mean a very long tenure and high total interest | Compare the total repayment and the APR |
| Not checking the APR | Fees are left out of the headline rate | Ask for the Key Fact Statement |
| Borrowing the maximum | A bigger loan means more interest and risk | Put in a larger down payment |
| Skipping the budget for running costs | Fuel, insurance, service and parking add up | Add them to the monthly cost |
| Taking the dealer's first offer | You may miss better terms | Compare at least two other offers |
| Accepting add-ons unseen | Bundled insurance, extended warranty and accessories add cost | Ask for each price and decide separately |
| Ignoring prepayment terms | You may be charged to close early | Ask for the rule in writing |
| Signing blank or incomplete forms | Details can be filled in later without your knowledge | Sign only completed forms and keep copies |
| Applying to many lenders at once | Too many lender checks in a short time can lower your score | Apply only where you are likely to qualify |
| Forgetting to remove hypothecation | The lender stays on the record after you repay | Follow up for the closing papers |
Mistake 1: Looking only at the EMI
Worked example: a ₹8,00,000 loan can be made to look affordable by extending the tenure. A longer tenure lowers the EMI, but you pay interest for more months, so the total cost rises. Test shorter and longer tenures in the EMI calculator and compare the total, not only the monthly figure.
Mistakes 2 and 3: APR and the loan amount
The APR includes fees as well as interest. Ask for the Key Fact Statement, which sets out the APR, the total cost and the charges. Then decide on the loan amount. Borrow only what you need, and pay as much as you comfortably can upfront. See car loan down payment.
Mistake 4: Leaving out running costs
The EMI is only part of owning a car. Add fuel, insurance, servicing, tyres, parking and tolls. If the total takes you past what you can afford, choose a cheaper car or a smaller loan.
Mistakes 5 and 6: Offers and add-ons
A dealer may offer a loan along with the car. It may be good, but compare it with offers you find yourself. Add-ons such as extended warranty, accessories and bundled insurance may be priced into the loan, so you pay interest on them. Ask for each price separately and decide whether you need it.
Mistake 7: Not asking about early repayment
You may want to repay early with a bonus or savings. Ask whether you can part-pay, whether there is a minimum amount, and what charge applies. Car loans are often fixed-rate, so the RBI rule that bars prepayment charges on floating-rate loans to individuals for non-business purposes may not apply. The lender's own terms will. See loan prepayment and foreclosure.
Mistakes 8 to 10: Papers and process
- Read the sanction letter and the agreement fully. Ask about anything you do not understand.
- Do not sign blank forms or cheques with the amount empty.
- Keep copies of the invoice, insurance, RC and every receipt.
- Confirm that the loan is paid to the dealer or your account and that you get a receipt.
- After repaying, get a no-objection letter and ensure hypothecation is removed from the RC.
Many of these mistakes come from rushing. A car purchase moves fast: the dealer wants a booking amount, the delivery date is fixed, and the loan papers appear at the last minute. Slow the process down. Ask for the loan documents a day before you sign, read them at home, and ask a family member to check the numbers with you. If something does not match what you were told, ask for it in writing or walk away. A good lender will not mind your questions, and a rushed signature is the one you will regret.
Five myths
Common myths
| Myth | The facts |
|---|---|
| A bigger loan is better because it keeps savings free | A bigger loan means more interest and a higher EMI. Keep a balance between savings and borrowing. |
| A small EMI means a cheap loan | A low EMI often means a long tenure and higher total cost. |
| The dealer's loan is always the easiest and cheapest | It may be easy, but compare it on APR and charges. |
| Checking my credit score will lower it | Checking your own score does not lower it. A lender's check in an application is recorded as an enquiry. |
| Once I sign, I cannot change anything | You can ask about prepayment, part-payment and refinance. Terms depend on the lender and your agreement. |
Frequently asked questions
What is the biggest car loan mistake?
Looking only at the EMI. It hides tenure and fees. Compare the total repayment and the APR.
Should I buy the extended warranty through the loan?
Ask its price and what it covers, and decide separately. If it is added to the loan, you pay interest on it.
Do I have to buy insurance from the lender or dealer?
Lenders require cover, but you may be able to choose your own insurer. Ask before you agree.
Can I change the tenure after the loan starts?
Some lenders allow it. Ask about the charge and whether the rate changes.
What if I find an error in my agreement after signing?
Write to the lender at once and ask for a correction. Keep proof. If it is not fixed, use the lender's grievance process.
How do I know the dealer is not overcharging?
Ask for an itemised invoice and compare the on-road price with quotes from others. Make sure the loan amount matches the invoice.
