How much car can I afford on my salary?
Most people buy a car based on one number: the monthly payment the dealer quotes. That's the trap. A salesperson can make almost any car "fit" your budget by stretching the loan to 6 or 7 years — but you end up paying thousands extra in interest and owing more than the car is worth.
The honest way to figure out how much car you can afford is to work backward from your total transportation cost — the loan payment plus insurance, gas, and maintenance — and keep that whole number inside a safe slice of your income. This calculator does exactly that.
The quick answer by salary
Here's a realistic max sticker price using the safe 10%-of-income guideline, average insurance and running costs, a modest down payment, and a 4-year loan. Type your exact number into the calculator above for your real figure.
Notice these are lower than what a dealer will approve you for. Getting approved for a loan and being able to comfortably afford it are two very different things.
Why "true cost" matters more than the payment
A $450 car payment isn't really $450. Add roughly $150–$250 a month for full-coverage insurance, $100–$200 for gas, and $50–$100 set aside for maintenance, and that $450 payment is closer to $800 a month in real life. The calculator above adds all of that in so you don't get blindsided after you sign.
The 20/4/10 rule, explained simply
It's the simplest guardrail in car buying. Put 20% down so you start with equity instead of being underwater. Finance for 4 years max so you don't drown in interest. Keep all car costs under 10% of your gross monthly pay. Hit those three and you almost never end up "car poor."
Where our numbers come from
Average car payment, insurance, and pricing figures are based on published 2025–2026 data from sources like Edmunds, Kelley Blue Book, Experian, and AAA. Loan math uses a standard amortization formula. These are estimates to plan with — your real rate and insurance depend on your credit, location, and the exact car. Always confirm final numbers with your lender and insurer.
