The 20/4/10 Rule

The most widely recommended guideline for how much car you can comfortably afford without straining your budget.

20%

Down payment

Put at least 20% down to avoid being upside-down on your loan and to keep monthly payments manageable.

4 yr

Loan term

Keep your loan to 4 years (48 months) or less. Longer terms mean more interest and a car that loses value faster than you pay it off.

10%

Of gross income

Your total monthly car costs — payment, insurance, and maintenance — should stay under 10% of your monthly gross income.

01

Buy 1-3 years used

New cars lose 20-30% of their value in the first year. A lightly used car gets you 80% of the experience at 60% of the price.

02

Get pre-approved first

Walk into the dealership with a pre-approved rate from your bank or credit union. You'll have real leverage to negotiate.

03

Budget for total cost

Don't forget registration, taxes, maintenance, and gas. A $400/mo payment becomes $600/mo in real cost of ownership.
