Car Payment Calculator

How to use this car payment calculator

Start with the selling price of the car. That is the price before tax, title, registration, and dealer fees. If the dealer gives you an "out-the-door" price, that number may already include tax and fees.

Then add your down payment, trade-in value, and any rebate. A $5,000 down payment on a $35,000 car lowers the loan before tax from $35,000 to $30,000.

If you have a trade-in, enter both numbers: what the dealer gives you and what you still owe. Those are not the same thing. Blending them is how old debt sneaks into a new car with sunglasses on.

Add sales tax and fees if you plan to finance them. Then choose the APR and loan term. APR means annual percentage rate. Plain English: it is the yearly price of borrowing money.

With your current entries, a $35,000 car, $5,000 down, $700 in fees, 6.25% sales tax, 7.5% APR, and a 60-month term gives a payment of about $659 per month.

Car payment with tax, fees, and trade-in

The sticker price is not the full price. That is the first uncomfortable truth.

A car can be listed for $35,000 and still cost more once tax, title, registration, and dealer fees show up. Some fees are real. Some are padded. All of them deserve eye contact.

Here is the same tax, fee, and trade-in logic using your current entries: $35,000 car, $5,000 down, 7.5% APR, 60 months, 6.25% sales tax, and $700 in fees.

The trade-in helps twice in this example. It lowers the loan amount. It may also lower the sales tax because the taxable amount drops from $35,000 to $31,000.

That tax credit is not universal. Some states tax the full price before trade-in. Some tax only the difference. Before you sign, ask the dealer to show the taxable amount on the buyer's order.

The buyer's order is the paper that lists the selling price, taxes, fees, trade-in, loan amount, and total cost. it is where the magic trick either gets caught or becomes your problem.

What fees should you include in a car payment calculator?

Include any fee you plan to finance. That can mean doc fees, title, registration, dealer fees, electronic filing fees, add-ons, and an extended warranty if you roll it into the loan.

If you pay a fee upfront, do not add it to the loan amount. If you borrow it, add it. Monthly math is sneaky. It turns a $2,000 decision into a $40 shrug.

Should you use sticker price or out-the-door price?

Use the sticker price if you are entering tax and fees separately. Use the out-the-door price if it already includes tax, title, registration, and dealer fees.

Out-the-door price means the full price to buy the car before financing. If the dealer says the car is $35,000 before taxes and fees, enter $35,000 and add tax and fees.

If the dealer says the out-the-door price is $37,888, enter $37,888 and set tax and fees to zero. Double counting is easy. It is also expensive. Math does not care that the form was confusing.

Can I roll taxes and fees into my car loan?

Usually, yes. That does not make them free.

Rolling taxes and fees into the loan means you borrow them. If you borrow them, you pay interest on them. A $700 fee rolled into a 60-month loan at 7.5% APR adds about $14 per month. It sounds small because monthly math is a magician. Over the whole loan, it costs about $842 after interest.

A $2,000 add-on at 7.5% APR for 60 months adds about $40 per month. It also adds about $405 in interest. That is why the question is not only, "Can I afford the payment?" The better question is, "Do I want to finance this cost for five years?"

What if I owe money on my trade-in?

This is called negative equity. you owe more on the old car than the old car is worth.

Say your trade-in is worth $2,500, but your payoff is $4,000. You are $1,500 short. That $1,500 does not vanish. It usually gets added to the new loan.

On a $35,000 car with $5,000 down, that can turn a $30,000 loan into a $31,500 loan. At 7.5% APR for 60 months, the payment rises to about $631.

The old car is gone. The old debt is not. Rude, but useful to know.

Before you trade in a car, ask for two numbers in writing: the trade-in value and the loan payoff amount. Do not let anyone blend them into one friendly payment. Friendly payments have caused enough trouble.

How rebates and cash incentives change your payment

A rebate can lower your loan if it reduces the price or acts like extra down payment. In the calculator, enter it as a rebate only if it applies to this deal.

Take the tax-and-fee example above. The amount financed is $32,888. The payment is about $659 per month. Add a $1,500 rebate and the payment falls to about $629.

Good. But do not stop there. Sometimes a rebate comes with a higher APR. Sometimes it distracts from fees. Ask, "What is the selling price before the rebate?" Tiny sentence. Useful spine.

What your monthly payment does not include

A car loan payment is not the real monthly cost of the car. The loan is only one bill. You may also pay for insurance, gas, maintenance, registration, parking, tolls, tires, oil, and repairs.

Using the calculator's default loan-only example, the payment can start around $601. Add normal ownership costs and the number changes fast.

That is the number your budget feels. Not $601. $1,066. This is why a payment can look fine at the dealership and feel heavy at home. The dealership is not paying your insurance bill. Very generous of them to leave that part to you.

How loan length changes the real cost

Longer loans lower the monthly payment. They also keep you in debt longer and raise total interest. For a $30,000 loan at 7.5% APR, here is what happens.

The 84-month loan looks easier because $460 is smaller than $601. That part is true. But the 84-month loan costs about $2,584 more in interest than the 60-month loan. It also keeps you paying for two extra years.

If you need 84 months to make the car fit, the car may be too expensive. That is not a moral failure. It is a math signal.

How a car loses value over time

A new $30,000 car is modeled around $24,000 after the first-year drop and about $17,700 by year three. That is not your loan balance — that is the car's actual worth.

The buyer who waits and buys a three-year-old car pays around $17,700 for the same vehicle and skips the steepest part of the curve. They still have depreciation ahead — just far less of it.

If you spend that same $30,000 on a used car instead, this model keeps it closer to $21,000 after three more years because someone else already paid for the steep first drop. Same budget, different curve. Very annoying. Also very useful.

This is why a 60-month loan on a new car can put you underwater fast. If the car is worth $17,700 at year three but you still owe $18,000 on the loan, you are paying off a debt bigger than the asset. That gap has a name: negative equity. The calculator's affordability section helps you size the loan to stay above water.

Depreciation as a monthly cost. Lost value is not a bill, so most people skip it. That is how it sneaks up on you. If a $30,000 car is worth about $17,700 after three years, that is $12,300 in lost value — roughly $342 per month spread over those 36 months. Add that to your all-in monthly cost above and the loan payment looks less like the full story.

New vs. used, side by side. Used usually wins on payment and depreciation. New usually wins on warranty and early repairs. The right answer is the lower honest total, not the shinier dashboard.

The used car saves about $195/month here. One $1,800 repair erases nine months of that gap. So the question is not "new or used" — it is "which one lands cheapest in my real budget across the whole year." Plug your numbers into the all-in calculator above and let the math decide.

How much car can I afford?

A good rule is to keep the car payment under 10% of take-home pay. Take-home pay means the money that actually lands in your bank account after taxes and deductions.

For $5,000 in monthly take-home pay, a 10% payment target is $500. Another useful rule is to keep total transportation near 15% of take-home pay. That includes payment, insurance, gas, and maintenance.

For $5,000 in take-home pay, 15% is $750. Now compare that with the loan-only example. The payment is about $601. The all-in cost can reach $1,066.

That does not mean the car is forbidden. This is not a courtroom. It means the car needs a real budget check before you sign. If your all-in car cost is close to 20% of take-home pay, something else in your budget has to bend. Rent will not volunteer. Groceries are also famously stubborn.

The 20/4/10 rule, plain English. Put 20% down. Pick a loan four years or shorter. Keep total transportation under 10% of income. It is conservative on purpose — rules of thumb are guardrails, not goals. If your numbers do not hit 20/4/10, use the affordability widget above to find what your numbers actually allow. The point is to leave room for everything else your life is also paying for.

What APR means for your car payment

APR changes the payment more than people expect. APR means annual percentage rate. It is the yearly cost of borrowing. Higher APR means the lender takes more money for the same car.

Here is a $30,000 loan for 60 months at three APRs.

The gap between 6% and 12% is about $87 per month. Over 5 years, it is about $5,241 more. That is why shopping for a loan before going to the dealer matters. A better rate is not glamorous. It is just money you keep.

Check banks, credit unions, and online lenders. Bring the best offer with you. Then the dealer has to beat it, not invent the starting line.

Current auto loan rates in 2026

Your interest rate is determined mostly by one thing: your credit score. Everything else — the dealer, the lender, the car — is secondary. Here is where rates actually land, based on Experian's most recent automotive finance data.

Source: Experian State of the Automotive Finance Market, Q4 2025.

The gap between super prime and deep subprime is not a rounding error. On a $30,000 loan for 60 months, the difference between 4.66% and 16.01% is roughly $180 per month — and about $10,800 over the life of the loan. That is a used car's worth of money paid directly to the lender. Test your rate in the calculator above before you test-drive anything.

Used car loans run significantly higher than new car loans at every credit tier. The national average for used car loans across all borrowers was 11.26% in Q4 2025, versus 6.37% for new cars. A newer car can cost less to finance even if it costs more to buy. Worth running the numbers both ways.

How much car can you actually afford on your income?

The 10% rule says your car payment should stay under 10% of monthly take-home pay. The 15% rule says total transportation — payment, insurance, gas, maintenance — should stay under 15%. Here is what those rules look like at different income levels, assuming $1,000 down, 7.5% APR, and a 60-month term.

Look at the "room left" column before you look at the car price column. Insurance alone averages $150–$250 per month for full coverage, depending on your state, age, and driving history. Add gas and maintenance and that $150 buffer disappears fast at the $3,000 take-home level. The rule is not a guarantee of comfort. It is a floor, not a ceiling.

One more thing the table does not show: the down payment comes from savings you already have. If you are draining your emergency fund to put $1,000 down on a car, you are borrowing against your safety net. That is a separate conversation worth having before signing anything.

Car sales tax: what gets taxed and where

Sales tax is one of the most misunderstood parts of a car purchase. Most people know it exists. Fewer know the rules that govern it — and the rules can shift your total cost by hundreds of dollars.

Five states with no car sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon. If you buy and register a car in one of these states, there is no state sales tax on the purchase. None. It is a meaningful advantage if it applies to you.

States where your trade-in does not reduce your taxable amount: In most states, you only pay sales tax on the price of the new car minus your trade-in value. If the car is $35,000 and the trade-in is $5,000, you are taxed on $30,000. That saves real money.

But in California, Hawaii, Kentucky, Maryland, Michigan, Virginia, and Washington D.C., the trade-in does not reduce the taxable base. You pay tax on the full $35,000 regardless. At a 7% tax rate, that is $350 extra — not catastrophic, but not nothing either.

The practical takeaway: before you assume your trade-in will lower your tax bill, ask the dealer to show you the taxable amount on the buyer's order. Do not let it live in a verbal approximation. The math is either there in writing or it is not confirmed.
