Out-the-Door Price Calculator

The Out-the-Door Price Calculator shows the true, final cost of buying a car — not just the sticker price or the monthly payment. It adds sales tax, the documentation fee, title, registration, and any dealer add-ons to the negotiated price, subtracts your rebate, and accounts for your trade-in — including the sales tax a trade-in credit can save you. You also get an animated cost build-up, your amount to finance with a monthly payment estimate, and an optional check against a dealer's quote to catch padded fees.

What Is the Out-the-Door Price?

The out-the-door (OTD) price is the grand total you actually pay to take a vehicle home. Dealers love to advertise a low sticker price or an attractive monthly payment, but those numbers leave out taxes and fees that can add thousands. The out-the-door price puts every charge on one line so you can compare offers fairly and know exactly what you are signing up for.

Out-the-Door Price Formula

The calculation runs in two short steps: find the sales tax on the taxable amount, then add up the price, tax, and fees and subtract the rebate.

^* The trade-in is subtracted from the taxable amount only in states that offer a trade-in tax credit. The calculator lets you switch this on or off.

How a Trade-in Saves You Sales Tax

In most US states, your trade-in reduces the amount that is taxed, not just the amount you owe. If you buy a $30,000 car and trade in a vehicle worth $10,000 in a state with a 7% sales tax, you are taxed on $20,000 instead of $30,000 — a saving of $700. A small number of states (such as California and Virginia) do not give this credit, so the calculator includes a switch to match your state's rule. When the credit applies, the result highlights exactly how much sales tax your trade-in saved.

How to Avoid Junk Fees

• Ask for the out-the-door price in writing before you ever discuss a monthly payment.
• Request an itemized buyer's order and compare it against this calculator's estimate.
• Question unfamiliar lines — nitrogen tires, VIN etching, paint sealant, and "market adjustments" are usually optional.
• Know the legitimate charges: sales tax, doc fee, title, and registration. Almost everything else can be negotiated or declined.

Frequently Asked Questions

What is the out-the-door price of a car?

The out-the-door (OTD) price is the total amount you pay to drive a car off the lot. It is the negotiated vehicle price plus sales tax, documentation fee, title fee, registration, and any dealer add-ons, minus rebates. Unlike the sticker or monthly payment, the out-the-door price shows the full, final cost of the purchase.

What is included in the out-the-door price?

A typical out-the-door price includes the vehicle sale price, state and local sales tax, the dealer documentation (doc) fee, the title fee, registration and license fees, and any optional dealer add-ons such as paint protection or extended warranties. Manufacturer rebates and incentives are subtracted from this total.

Does a trade-in reduce the sales tax I pay?

In most US states, yes. A trade-in tax credit means you only pay sales tax on the price after the trade-in is subtracted. For example, on a $30,000 car with a $10,000 trade-in and a 7% tax rate, you pay tax on $20,000 instead of $30,000, saving $700. A handful of states do not offer this credit, so the calculator lets you turn it on or off.

How is the out-the-door price calculated?

First, sales tax is found on the taxable amount, which is the vehicle price minus the trade-in if your state credits it. Then the out-the-door price equals the vehicle price plus the sales tax plus all fees and add-ons, minus any rebate. The amount you finance is the out-the-door price minus your down payment and trade-in value.

What is a documentation or doc fee?

A documentation fee, or doc fee, is what a dealer charges to prepare and process the paperwork for your purchase. It varies widely, from under $100 to several hundred, and some states cap it. Because it is largely profit, the doc fee is one of the most negotiable line items on an out-the-door quote.

How can I avoid junk fees at the dealership?

Always ask for an itemized out-the-door price in writing before agreeing to buy. Compare it with this calculator's estimate and question any line you do not recognize, such as nitrogen-filled tires, VIN etching, or paint sealant. Legitimate charges are sales tax, the doc fee, title and registration. Add-ons are optional and can usually be removed.
