Your real borrowing power depends on credit approval, and the rate you're quoted may differ from the one entered here. Sales tax rules vary by state — some tax the price after a trade-in credit rather than before, which would let you afford slightly more. Estimate only, not financial advice.

Start with what you can comfortably spend each month and work backwards to the car price it actually buys — after insurance, sales tax, and dealer fees take their cut.

Found your number? The auto loan calculator runs it the other way — enter a specific car's price and see the payment and full amortization. If you're not sure what you can spend, start with your actual take-home pay.
How it works
Most car shopping runs the wrong direction: you find a car, then find out what it costs per month. This runs it the way a budget actually works. Your monthly figure sets how much you can borrow, your down payment and trade-in add to that, and sales tax and fees come off the top — what's left is the sticker price you can afford.
Two things make the answer smaller than people expect. The first is that a car payment isn't the cost of owning a car. Insurance, fuel, and maintenance are real monthly money, and if you budget $600 without accounting for them, you'll end up spending well past $600. That's why they get their own field here and are subtracted before anything is financed. The second is tax and fees. They're charged on top of the price, so every dollar they take is a dollar of car you don't get.
Example: a $600 monthly budget with $150 going to insurance and fuel leaves $450 for the payment. At 7.5% APR over 60 months that borrows $22,457. Add $4,000 down and a $2,000 trade-in, subtract $800 in dealer and registration fees, and after 7% sales tax it works out to a car priced around $25,848 — about $28,457 out the door, with $4,543 of that being interest.
Stretching the same budget to a 72-month loan lifts the affordable price to roughly $29,184. That's $3,300 more car for the same monthly payment, which is exactly why long terms are offered so readily — but it costs $6,374 in interest instead of $4,543, and you spend two extra years owing money on a depreciating asset. A longer term buys a nicer car, not a cheaper one.

FAQ
There's no official standard, and anyone quoting one precise percentage is repeating a rule of thumb rather than a rule. The commonly cited version is to keep the total of all car payments near or under 10% of your take-home pay, put 20% down, and finance no longer than four years. It's a reasonable starting point, not a law — someone with no other debt and a short commute can justify more than someone carrying student loans. The more useful test is whether the payment still works on a bad month, not an average one.
Yes, and it's the single biggest reason affordability estimates come out too high. A car's monthly cost is the payment plus insurance plus fuel plus maintenance, and for an inexpensive car those extras can rival the payment itself. Insurance in particular varies enormously by driver, location, and vehicle — a sportier model can cost noticeably more to insure than a sensible one at the same price. Get a real insurance quote for the specific car before you commit, since you can't renegotiate it later the way you can a rate.
It means you can afford a bigger price tag at the same monthly payment, which isn't the same thing. Stretching from 60 to 72 months in the example above adds about $3,300 of car and about $1,800 of interest. It also keeps you underwater longer — owing more than the car is worth — because the loan pays down slower than the car depreciates. If a car only fits your budget on an 84-month term, that's usually the calculator telling you it's the wrong car.
They reduce it, because they're charged on top of the negotiated price rather than included in it. On a $26,000 car, 7% tax plus $800 in fees is roughly $2,600 you have to cover before you've bought any more car. This calculator subtracts fees from your cash on hand and applies tax to the price, which is how most deals are structured. One wrinkle: some states charge sales tax on the price after your trade-in is credited rather than before, which would let you afford a bit more than shown here — check how your state handles it.
Affordability and approval are different questions. This tells you what fits your budget; a lender decides what fits their risk model, using your credit history, income, and debt-to-income ratio. You may be approved for considerably more than you should borrow — being approved is not advice. The rate matters too: the APR you're offered depends on your credit, so getting a pre-approval from your own bank or credit union before you walk in gives you both a realistic rate to enter here and a number to negotiate against.
