Dream Car, Debt Nightmare? Avoid Loan Regrets With 20/4/10 Formula – Details | Auto News

What 20/4/10 Says?

20% Down Payment: It directs buyers to pay at least 20% of the car’s on-road price upfront as a down payment. This reduces the loan amount you need for the vehicle and helps to lower the EMI.

4-Year Loan Term: This formula says loan tenure should be more than 4 years, which is 48 months. It reduces the interest amount paid over the tenure. It helps to ensure you don’t end up owing more on the loan than the car is worth.

10% Of Monthly Income: It advises you the total monthly car expense (including loan payment, insurance, and maintenance) should be under 10% of your monthly gross income. This ensures that your car expenses will not put extra stress on your overall budget.

Let’s Take An Example

Suppose you want to buy a car that costs you Rs 10,00,000, on-road. Here’s how you would apply the 20/4/10 rule:

Down Payment (20%): 20% of Rs 10,00,000 = Rs 2,00,000 (Must be paid as a down payment)

Loan Tenure (4 Years): Finance the remaining Rs 8,00,000 for a maximum period of 4 years (48 months).

Monthly Income (10%): Suppose your monthly gross income is Rs 1,00,000. In that case, 10% of Rs 1,00,000 = Rs 10,000 (Total monthly car expenses should not exceed this).

Breakdown

Assuming an interest rate of 9%, a 4-year loan of Rs 8,00,000 would have an EMI of approximately Rs 19,912 (excluding all other expenses).

If insurance and maintenance are estimated to be Rs 2,000/month, your total monthly car expenses would be Rs 21,912 (Rs 19,912 + Rs 2,000), which exceeds 10% of your gross monthly income, indicating that the car might be too expensive for you based on the rule.
