Practical Worked Example

A buyer purchases an Rs 12,00,000 SUV with an Rs 2,00,000 down payment and takes an Rs 10,00,000 loan at 9.25% for 5 years.

01.Loan principal = Rs 12,00,000 − Rs 2,00,000 = Rs 10,00,000.
02.Monthly EMI = Rs 20,880 / month.
03.Total Repayment = 60 × Rs 20,880 = Rs 12,52,800.
04.Total Interest = Rs 2,52,800.
Rs 20,880 / Month (Rs 2.53L Interest)Putting down at least 20% down payment keeps monthly auto EMIs affordable and avoids negative equity.

Interpretation & Industry Benchmarks

Automobiles are depreciating assets; keeping loan tenures under 4-5 years prevents owing more on the car than its market resale value.

20/4/10 RuleBest Practice

20% down payment, 4-year max tenure, monthly auto payment under 10% of monthly income.

Industry Nuance: New cars lose approximately 15%–20% of their value in the first year of ownership.

Analytical Limitations

  • Does not include annual vehicle insurance, fuel costs, or periodic maintenance.
