How Much Car Can I Afford? The EMI Rule
There's no single official rule for car affordability in India, but a simple framework - 20% down, a 5-year loan cap, and 15% of take-home pay on car costs - gives you a defensible budget in under a minute.
The 20/5/15 rule
Think of it as three guardrails, not a law:
- 20% down payment - most lenders will finance 80-90% of the on-road price, but putting down at least 20% keeps you from being upside-down on the loan if you need to sell early.
- 5-year (60-month) loan cap - Indian car loans commonly run up to 7 years, but every extra year adds interest. Keeping the tenure to 5 years or less limits how much you pay the bank rather than the dealer.
- 15% of take-home pay - keep your EMI plus insurance under 15% of your monthly in-hand salary. It's tighter than the "one EMI = one-third of income" ceiling some lenders use for approval, which is a lending limit, not a comfortable budget.
A different, commonly cited India rule of thumb says a car's on-road price shouldn't exceed your gross annual salary. The two approaches usually land in a similar range - use whichever is easier for you to reason about, and treat both as starting points, not hard limits.
Working example
Take a monthly gross salary of ₹75,000, and assume a car loan at roughly 10% p.a. over 60 months (actual rates vary by lender and credit score - compare a few before you commit):
Monthly gross income: ₹75,000
Max car budget (15%): ₹75,000 × 15% = ₹11,250/mo
Subtract insurance: ₹11,250 − ₹2,500 = ₹8,750/mo EMI
At ~10% p.a. over 60 months:
Max loan ≈ ₹4.1 lakh
Plus 20% down (~₹1 lakh):
Max on-road price ≈ ₹5.1 lakhQuick reference: income vs. car price
| Monthly Gross Income | Max EMI | Approx. On-Road Price |
|---|---|---|
| ₹40,000 | ₹4,500 | ~₹2.6 lakh |
| ₹60,000 | ₹7,000 | ~₹4.1 lakh |
| ₹75,000 | ₹8,750 | ~₹5.1 lakh |
| ₹1,00,000 | ₹12,000 | ~₹7.1 lakh |
| ₹1,50,000 | ₹18,500 | ~₹10.9 lakh |
Illustrative only - assumes ~10% p.a., 60-month tenure, and insurance scaled to the price bracket. Run your own numbers with the calculator below.
When it's okay to bend the rule
This is a guideline, not a law. You might reasonably stretch it if you have no other EMIs running, you're buying used (the steepest depreciation is already gone), or the car replaces a real commuting cost. The 15% ceiling is the part worth respecting most - once car-related EMIs cross 20-25% of take-home pay, it becomes the top reason budgets feel permanently tight.
If the EMI makes you hesitate before you've even added fuel and insurance, the car is priced above your budget - regardless of what the bank pre-approved.
