On a car loan or pay cash decision, pay cash if the money would earn less after tax than the loan costs you. For a ₹10 lakh car financed over 5 years at 8.63%, the EMI is ₹20,579 and the interest is ₹2.35 lakh. Borrowing only wins if the cash you keep grows by more than about 8.9% a year after tax, with the processing fee included.
That 8.63% is not a guess. HDFC Bank's fees page for new car loans says the rates it offered between April and June 2026 ranged from 7.60% to 14.00% and averaged 8.63%. Your own rate depends on the loan amount, tenure and credit score, so treat it as a middle case and replace it with your quote.
Car loan or pay cash: what the cash has to earn
Suppose you have ₹10 lakh and two choices. Pay it all to the dealer, or borrow ₹10 lakh and leave your ₹10 lakh invested, paying each EMI out of it.
The table shows what is left, or what you are short, after the last EMI in month 60. It assumes a ₹5,000 processing fee and ₹700 documentation charge paid up front, both before GST. Returns are assumed to compound monthly.
| Return on your cash, after tax | Loan route compared with paying cash |
|---|---|
| 5% | ₹1,23,470 worse |
| 7% | ₹63,783 worse |
| 8.63% | ₹8,762 worse |
| 10% | ₹42,334 better |
| 12% | ₹1,25,642 better |
The break-even is 8.87%, a little above the loan rate because of the fees. A return only counts if it is after tax. A deposit paying 7% leaves 4.9% for someone taxed at 30%, which is close to the first row of the table. To clear 8.87% after tax at a 30% rate, an investment would need to earn about 12.7% before tax, every year, for five years.
Some investments may do that. They also can fall for a year or two, and the EMI does not care. The loan's cost is certain, and the cash's return is a forecast.
The prepayment charge
A common plan is to borrow now, then repay early when cash arrives. Check the clause before relying on it.
HDFC Bank's page lists a foreclosure charge of 5% of the outstanding principal on new car loans taken on or after 1 December 2025. Closing the ₹10 lakh loan after 12 EMIs would leave ₹8,32,840 outstanding and cost ₹41,642. That is still smaller than the ₹1,54,964 of interest you would avoid, so early closure can pay, but the charge eats more than a quarter of the saving.
SBI's page for its new car loan scheme says there are no prepayment charges, and no foreclosure charges after 2 years. Lenders differ here, and the difference can matter more than half a point of interest.
When borrowing is the better choice
Pay cash only from money that is actually idle. If paying ₹10 lakh would drain your emergency fund, borrow part of it or all of it. The emergency fund guide explains how much to hold back.
A loan also makes sense if the cash is earmarked for something that cannot wait, such as a down payment on a house or a child's fees due next year. Keeping cash available costs you the interest on the loan, and for some households that is worth paying.
Tenure is the other lever. The same loan over 7 years has an EMI of ₹15,902 but costs ₹3.36 lakh in interest, which is ₹1.01 lakh more than the 5-year version. If you borrow, pick the shortest tenure whose EMI you can carry comfortably.
Do this before you sign
Ask two lenders for a written quote that shows the rate, the processing fee, the documentation charge and the foreclosure clause. Put the rate and tenure into the car loan calculator, then compare the interest with what your cash earns after tax. If the break-even is above anything you can safely earn, pay cash and keep your emergency fund separate. The car affordability calculator checks whether the EMI fits your income, and the car loan EMI table shows other amounts and tenures.
