Personal loan vs car loan: where the costly part hides

Two features follow from the security. The first is the loan-to-value: lenders commonly fund 80 to 90 percent of on-road or ex-showroom price, depending on the lender and the model, and the rest is your margin. The second is that the car is the collateral, so its value matters. Depreciation is typically steep in the first year, which is why lenders cap the funded share, and why older used cars get a lower loan-to-value, a higher rate, or no loan at all.

A personal loan has none of this. It is priced on you: income, credit history, what you already owe. There is no asset to fall back on, so the rate carries that risk. Illustratively, a bank personal loan sits in the 10.5 to 14 percent band while a new-car loan sits several points below it. The gap is not a promotion. It is the price of the lien.

A ₹10 lakh on-road car with a car loan at 85 percent leaves ₹1.5 lakh to be found. The dealer will suggest where to find it, and the suggestion is rarely the lowest-cost option.

What the car loan typically does not cover: the margin money, the 10 to 20 percent the lender leaves to you; often the first year's insurance and registration, unless the lender funds on-road price; extended warranties and accessories, which are dealer margin; and a used car beyond a certain age, which many lenders will not finance at all.

What fills the gap is the interesting part. Some pay it from savings, right if the savings exist without emptying the emergency fund. Many put it on a credit card, fine if cleared inside the interest-free window and ruinous if not. And many take a small personal loan, because the amount feels small next to the car. That loan is priced at the unsecured rate, and it is the piece nobody compares.

₹8 lakh over 60 months, a common tenure for a new car. Illustrative rates: 9 and 11 percent for the car loan, 12 and 14 percent for a personal loan of the same size. Reducing-balance EMIs, no fees.

Say the car loan covers ₹8 lakh and the buyer needs ₹1.2 lakh for the margin, first-year insurance and accessories. A personal loan for that at an illustrative 14 percent over 36 months has an EMI of ₹4,101 and costs ₹27,647 in interest. The same ₹1.2 lakh at the car loan's 9 percent would have cost ₹17,375, so the unsecured slice costs ₹10,272 more. That is the hidden price of a car loan that stops at 85 percent.

The combined picture lands in one month. Car EMI ₹16,607 plus margin EMI ₹4,101 is ₹20,708, before fuel and before the second year's insurance, which is not an EMI but arrives just as reliably.

The rate gap that makes this easy on a new car narrows on an older one and can close entirely. Lenders price used-car loans higher because the collateral is worth less and harder to value, and past a certain age they stop lending against it. An illustrative 13 percent on a used car is not unusual.

A ₹4 lakh used car over 48 months at 13 percent has an EMI of ₹10,731 and costs ₹1,15,088 in interest. A personal loan at the same 13 percent costs exactly the same, because the rate is the only thing separating them. At 14 percent the personal loan costs ₹9,580 more; at 11 percent the used-car loan costs ₹18,854 less. On a used car, get the two actual quotes; the label tells you nothing.

The other place the gap moves is tenure, and it moves against you. Car loans run up to 84 months, and the long tenure is what makes a bigger car's EMI fit.

There are honest cases for the unsecured route, and they share one feature: the car loan is unavailable or not meaningfully cheaper.

A used car the bank will not finance. Past the lender's age cut-off, or bought privately without the paperwork a lender wants, the choice is a personal loan or cash, and the comparison is against not buying.

A very small amount. If you are borrowing ₹1 lakh against a ₹6 lakh car because the rest is coming from savings, the rate gap on ₹1 lakh over two years is a few thousand rupees, and the hypothecation and closure paperwork may not be worth it to you. Run the number; it is small enough that convenience can legitimately win.

A specific reason not to hypothecate. Someone who expects to sell within a year, or move the car between family members, is paying for that freedom. It is a real preference with a real price, and the table above says what the price is.

Any new car. If a lender will fund it at a secured rate, a personal loan instead is paying ₹71,332 on ₹8 lakh for the right to have no lien, which you were never going to exercise.

Funding the down payment with a personal loan so the car loan can be bigger. This does the most damage, and it is common. The margin is the only part of the purchase that tests whether you can afford the car. Borrow it and the test disappears; the on-road price gets set by what two EMIs can carry rather than by what you have. If the margin has to be borrowed, the car is one size too large.

Before signing either loan, five things are worth checking, and none is the rate.

The page found the expensive borrowing in the margin slice, and the real test of the car in whether the combined EMIs fit what actually lands each month. The app supplies the committed side of that test. From bank and card transaction emails and, on Android, transactional SMS, on Pro, it predicts what the coming month is already committed to, from existing EMIs and insurance premiums to bills on a cycle, so a car EMI and a margin EMI are added to a real baseline rather than a remembered figure.

If you are weighing a loan for the margin, the eligibility check pulls your credit report and shows the score and accounts behind it before any application, and you can compare personal loan offers from lenders you are eligible for against the rate the car lender quotes. The lender decides rate, amount and approval; the app earns a commission from lenders on loans taken through it and gives the diagnosis free.

It never asks for your bank password or UPI PIN, and every payment is one you authorise. Once the car loan closes, have the hypothecation removed from the RC.
