- 20% down payment
- 4 years maximum loan tenure
- EMI not more than 10% of your monthly income
This rule ensures that your car purchase does not affect your ability to manage other financial commitments like rent, savings, or investments.

Getting Car loans are easy, but easy loans can lead to big EMIs and longer tenures which may hurt your future plans. By following this rule:

- You keep your monthly budget stable
- You can manage emergencies better
- You build healthy borrowing habits
It’s especially helpful for young professionals and middle-income families who apply for a used car loan or simply a car loan.

A. 20% Down Payment
Pay at least 20% of the car’s on-road price upfront.
- Reduces the loan amount
- Lowers the EMI
- Improves loan approval chances
B. 4-Year Loan Tenure
Keep the repayment period within 4 years.
- Shorter tenure = lower interest outgo
- Builds financial discipline
- You can sell or upgrade the car sooner
C. 10% of Monthly Income as EMI
Your car loan EMI should not exceed 10% of your take-home salary.
- Keeps EMI manageable
- Ensures other expenses (like rent, bills, savings) are not affected
- Allows room for fuel, maintenance, and insurance
How to Apply the 20-4-10 Rule in Real Life
Let’s say your monthly income is ₹50,000.
- 10% EMI limit = ₹5,000
- Use online EMI calculators to find how much loan you can take within this limit
- Based on a 4-year loan tenure, back-calculate the car budget that fits
- Add 20% of that car’s price as your minimum down payment
Example: Buying a Car Using 20-4-10 Rule
You want to buy a car that costs ₹8 lakh (on-road price).
Following the 20/4/10 rule:
- 20% down payment = ₹1.6 lakh
- Loan amount = ₹6.4 lakh
- Tenure = 4 years
- At ~10% interest rate, EMI ≈ ₹16,200
So your monthly income should be at least ₹1.6 lakh to stay within the 10% EMI cap.
If your income is lower, choose a less expensive car or increase the down payment.
Benefits of Using 20-4-10 Rule
