The 20/4/10 rule is a popular car buying rule used to avoid overpaying for vehicles. It suggests putting at least 20% down payment, financing for no more than 4 years, and keeping total monthly car expenses under 10% of gross monthly income.
Many buyers focus only on EMI and ignore fuel, insurance, maintenance, repairs and depreciation. This leads to financial stress and poor budgeting. A true affordability calculator should include total ownership cost, not just loan payment.

Can I buy a car with 0 down payment?
Possible, but usually risky and increases EMI burden.
