How Much Car Can I Afford Calculator
Forget the price the dealer waves at you. This works from your actual paycheck: the 15% rule, your real bills, your credit score’s real rate — and it tells you the most car you can buy without strangling your budget.
The car you are about to buy will sit outside overnight. These light it up and watch it for you — no wiring, no electric bill.

How the 15% rule works — and why it protects you
Here is the blunt truth: the car you can afford is not the car a lender will approve you for. Lenders approve payments that eat your whole paycheck, because the risk lands on you, not them. The 15% rule flips that. It says everything car-related — payment, insurance, gas, upkeep — should stay under 15% of what actually lands in your bank account. That is money you can hand over every month without holding your breath.
So this calculator works backwards. It takes 15% of your take-home pay, subtracts the cost of simply owning a car (the $250 starting guess covers insurance, gas, and small repairs — change it if your numbers differ), and what is left is your real max payment. Then it runs that payment through the average rate for your credit score — Experian Q2 2026 numbers, not made-up ones — to find the biggest loan that payment safely carries. Add your down payment, and that is your true price ceiling.
If the number feels small, hear this: it is not a verdict on you, it is a starting line. Two levers move it fast. A bigger down payment raises your price ceiling dollar for dollar and shrinks the interest you pay — it is the one obstacle worth attacking first. And six to twelve months of on-time payments can move your score into a cheaper rate band, which is why so many readers later use the refinance calculator to see what a better rate would save. Start with the car you can afford today. Let it rebuild everything else.

Questions, answered
How much car can I afford on my salary?
A workable rule: keep everything car-related — payment, insurance, gas, and upkeep — under 15% of your monthly take-home pay. On $3,200 take-home, that is $480 total, which leaves roughly $230 for the payment itself after a $250 insurance-and-gas estimate.
Does my credit score change how much car I can afford?
Yes, a lot. At the same payment, a buyer in the subprime band (19.10% average used rate, Experian Q2 2026) borrows far less than a prime buyer at 8.81%. The payment is the same — the interest eats the difference.
Is the 15% rule too strict?
It is a guardrail, not a law. If your rent is low and you have no other debts, 20% can work. If rent and bills already eat most of your check, even 15% can be too much — which is why this calculator also shows what is left over each month.
How does a down payment raise what I can afford?
Dollar for dollar. Every extra $1,000 down is $1,000 more car at the same payment, because the loan itself does not grow — and you pay interest on a smaller amount the whole way through.
Should I pick a 72-month term to afford a nicer car?
Be careful. A longer term lowers the payment but piles up interest, and with bad-credit rates you can owe more than the car is worth for years. A cheaper car on a shorter term almost always beats a nicer car stretched thin.
Cheap insurance for the car you worked this hard to afford: motion lights that scare off anyone creeping around it at night.
