Car Loan vs Personal Loan: Which Is Cheaper for Buying a Car in India? (2026)

By Nitish Bharadwaj · Published Aug 26, 2026 · 7 min

Car loans and personal loans can both fund the same vehicle purchase, but their costs differ significantly. Car loans — secured against the vehicle — typically charge 8.5–12% interest, while personal loans for the same buyer often run 12–18%. The lower rate and longer tenure (up to 7 years for car loans vs 5 for personal) make car loans the default choice. But personal loans make sense for used cars older than 5 years, buyers wanting a clean RC with no hypothecation, or situations where the bank's LTV falls short. This guide runs the numbers.

Two loan products can pay for the same car purchase, and your bank will approve either one — but the total interest you pay over a five-year tenure can differ by ₹60,000 to ₹1.2 lakh on a standard ₹8–10 lakh loan, depending on your credit profile and which route you take. The right answer isn't always the obvious one: car loans win on cost most of the time, but personal loans serve specific situations where a car loan either doesn't apply or creates practical problems at the RTO.

The Core Structural Difference

A car loan is a secured loan where the vehicle itself is the collateral. The bank registers a hypothecation against the car's RC (Registration Certificate), which means the bank's name appears as financier on your RC until the loan is fully repaid. You cannot sell or transfer the car without the bank's No Objection Certificate. A personal loan, by contrast, is unsecured — no collateral, no hypothecation entry on the RC, and the bank has no direct claim on the car if you default (beyond standard debt recovery). This structural difference drives most of the cost and eligibility differences below.

The Interest Cost Gap: A Real Example

Take a ₹8 lakh loan on a new car, with a credit score of 750+. A car loan from SBI or HDFC at approximately 9% p.a. over 5 years produces an EMI of roughly ₹16,600 and a total interest outgo of approximately ₹1.96 lakh. The same ₹8 lakh as a personal loan from the same lenders at a conservative 13.5% p.a. (typical for 750+ CIBIL) produces an EMI of approximately ₹18,300 and total interest of approximately ₹2.98 lakh. That's a ₹1.02 lakh difference on the same loan amount over the same tenure — before accounting for the typically higher processing fees on personal loans. For most buyers with a clear path to a car loan, this gap is the entire analysis.

When a Personal Loan Makes Sense for a Car Purchase

Car loans aren't available for every vehicle or situation. In these cases, a personal loan is the practical alternative — not always a more expensive one once you factor in what car loans won't finance:

• Used cars older than 5–7 years: Most banks won't finance a car this old under their car loan product; the maximum car age at loan end (typically 10–12 years) rules them out. A personal loan has no vehicle-age restriction.
• Very old or discontinued models: Some banks maintain a list of approved vehicle models. If yours isn't on it, the car loan application fails at underwriting. Personal loans don't care about the car's make or model.
• No down payment available: Car loans typically finance 80–90% of the on-road price. If you don't have the 10–20% down payment but qualify for a personal loan large enough to cover the full price, the personal loan removes the gap — though your total borrowing cost will be higher.
• Clean RC required for business use: If the car is used for a business where a hypothecation on the RC creates complications (some transporters, fleet operators), a personal loan lets the vehicle show a clean RC from purchase.
• Quick disbursement needed: Personal loan approvals and disbursements are often faster than car loan underwriting, which may require a valuation or dealership confirmation. If the deal needs to close in 24–48 hours, a pre-approved personal loan can complete the transaction.

Electric Vehicles: Does the Calculation Change?

EV financing has added a wrinkle to the car-vs-personal-loan question. Most banks now offer car loans on popular EVs (Tata Nexon, MG Windsor, BYD Atto), but the LTV offered is sometimes lower than for ICE vehicles — partly because residual values and battery replacement costs are harder to model. In some cases, borrowers find the car loan's LTV insufficient and need to bridge the gap with a personal loan, effectively using both simultaneously. Banks like HDFC and SBI have launched dedicated green vehicle loan products with slightly preferential rates; if your EV qualifies, those beat a standard personal loan. If it doesn't — particularly for newer brands or commercial EVs — the personal loan remains the fallback. For current bank-by-bank EV loan rates, financing limits, and what's actually still true about central purchase subsidies and the Section 80EEB tax deduction, see our dedicated electric vehicle loan guide.

The Tax Angle

For personal vehicle purchases (not business use), neither car loans nor personal loans offer any income tax deduction on interest — this distinction sometimes confuses people who know that home loan interest is deductible. The deduction ceases to apply the moment the loan's purpose is personal transportation rather than housing. The calculation changes if the car is used for business: under that scenario, interest on a loan used to purchase a business asset is deductible as a business expense under the Income Tax Act, regardless of whether it's structured as a car loan or personal loan. But for the typical individual buying a family car, no tax benefit applies to either product.

If you already have an active personal loan and are weighing prepayment versus taking additional car financing, prepayment terms on personal loans depend on the lender — foreclosure charges vary, so confirm with your bank before assuming penalty-free prepayment is available (note: the RBI ban on prepayment penalties applies to floating-rate home loans, not personal loans). Prepaying an existing high-rate personal loan before taking a car loan at a lower rate can still be a worthwhile option if your lender's terms allow it. For the decision framework on this, our personal loan balance transfer guide covers when switching lenders to a lower rate actually saves money after accounting for processing fees and remaining tenure.

The Bottom Line

For a new car purchase where a car loan is available: take the car loan, always. The interest rate, tenure, and processing-fee advantages compound meaningfully over 5–7 years. For used cars beyond 5 years old, unusual models, or situations where the RC needs to be clean: a personal loan is the appropriate tool, not a compromise. The question of which to choose is only genuinely open if you're near the boundary conditions — a 4–5-year-old used car in excellent condition, where some banks will offer a car loan and others won't. Run both quotes and compare total interest before deciding. And if you already took a car loan a couple of years ago at a higher rate and your CIBIL score has since improved, refinancing that existing loan rather than living with it may be worth more than any car-vs-personal-loan comparison for a new purchase — see our car loan balance transfer guide for when that switch actually pays for itself.
