How the Car Affordability estimate works

The calculator checks your purchase against the 20/4/10 rule, then reverses the EMI limit to estimate a safer target car budget from your income.

20% down payment

A larger upfront payment reduces the loan and helps avoid owing more than the car is worth.

4-year tenure

Keeping the loan to 48 months or less limits interest and avoids paying for the car long after its prime years.

10% EMI limit

The monthly EMI is checked against 10% of take-home income so the car does not crowd out investing and living costs.

Target budget

The tool estimates a maximum safe loan from the 10% EMI rule, then assumes that loan is 80% of the car price.

Worked Car Affordability example

For a ₹12 L car, ₹2 L down payment, 9% loan, 5-year tenure, and ₹80,000 monthly take-home income:

Down payment
~16.7%
Tenure
5 years
EMI ratio
~26%

This fails all three rule checks. At the same income and rate, the safer target budget is about ₹4.01 L using a 4-year loan and an ₹8,000 maximum EMI.

Assumptions & exclusions

The 10% limit applies strictly to EMI. Running costs like fuel, insurance, maintenance, and repairs must be budgeted separately.

The down payment is assumed to be saved cash, not borrowed through another loan.

The loan math uses a standard reducing-balance EMI model common for Indian car loans.

Frequently asked questions

Is the 20/4/10 rule too strict for India?

It is conservative, especially because car prices can be high relative to income. Treat it as an ideal wealth-protection rule; if you stretch it, do so knowingly because it reduces monthly investing capacity.

Why a 4-year limit when banks offer 7-year loans?

Cars depreciate quickly. A 7-year loan raises total interest and keeps you in debt while the car loses value. If the monthly payment only works at 7 years, the car may be too expensive for current income.

How should I interpret the result?

Use the target budget as your anchor. If the car you want is much higher, consider waiting, saving a larger down payment, raising income, or choosing a reliable used car.
