A ₹10 lakh car on a full 5-year loan at an assumed 9% costs about ₹12.45 lakh (EMI ≈ ₹20,760). Putting 20% down and borrowing for 4 years brings the total to about ₹11.56 lakh. Saving first for 3 years needs roughly ₹29,000 a month. The right choice depends on what else that money is meant to do.
We assume a ₹10 lakh on-road price, a 9% loan rate (rates vary by lender and profile), 7% growth on money saved in debt-like instruments and about 5% a year price rise on the car. These are assumptions, not promises.
| Option | Monthly outgo | Total paid | Interest / cost of waiting |
|---|---|---|---|
| 100% loan, 5 years | ≈ ₹20,760 | ≈ ₹12.45 lakh | ≈ ₹2.45 lakh interest |
| 20% down + 4-yr loan | ≈ ₹19,910 (+ ₹2 lakh now) | ≈ ₹11.56 lakh | ≈ ₹1.56 lakh interest |
| Save first, buy in 3 years | ≈ ₹29,000 saved | ≈ ₹10.4 lakh deposited | Car may cost ≈ ₹11.6 lakh by then |
The save-first route is the cheapest in rupees, but you do not have the car for three years. The loan routes cost more but give you the car from day one.
A home can hold or grow in value. A car usually loses value quickly, especially in the first few years. So interest on a car loan buys you convenience, not an asset that pays you back. That is why the usual advice is to keep the loan as small and short as possible.
A common rule of thumb is 20/4/10:
It is a guide, not a law. If the EMI crosses that line, a cheaper car is usually the better fix.
Paying the full ₹10 lakh from savings avoids interest, but the money may have been earmarked for something else, such as a child's education or retirement. If a 9% loan is replacing money that would otherwise be invested for a goal, compare the loan rate with the return you can reasonably assume on that goal money. Never drain your emergency fund for a car, whichever way you pay.
Treat the car as its own goal with its own SIP, not as a loan taken from other goals. If it is 3 years away, a debt-heavy mix suits it better than equity, since the money is needed on a fixed date. In the app, each goal gets its own SIP and the mix de-risks as the date nears.
For tax or loan-eligibility questions, check with a CA or your lender.
Q. Is it better to take a car loan or pay cash?
A. Cash is cheaper in interest, but only if it does not drain your emergency fund or goal money. A small, short loan after a decent down payment is a reasonable middle path.
Q. How much down payment should I make on a car?
A. A common guide is at least 20% of the on-road price. A larger down payment lowers the EMI and the total interest.
Q. Is a longer loan tenure better because the EMI is lower?
A. The EMI is lower, but total interest rises. In the example above, going from 4 to 5 years adds roughly ₹0.9 lakh of extra cost on the same car.
Q. What if I cannot afford the EMI under the 10% guide?
A. Consider a lower-priced car, a longer saving period or a bigger down payment rather than stretching the tenure.
