Out-the-Door Price Calculator
The number that matters is not the price on the windshield — it's what you pay to drive off. Enter your negotiated price and state, and get the full itemized build-up: vehicle tax with your state's trade-in credit rule, title, registration, and the doc fee with its statutory cap where one exists.
| Vehicle price | $35,000 |
| Sales tax (6.25%) | $2,188 |
| Title fee | $33 |
| Registration | $51 |
| Doc feeNo cap in Texas — $499 shown; dealers set their own. Negotiate it. | $499 |
| Estimated out-the-door price | $37,771 |
Texas charges a flat 6.25% motor-vehicle sales/use tax with no local add-on; on private-party used sales the tax is figured on the greater of price paid or 80% of the vehicle's Standard Presumptive Value (SPV), collected at registration.
Estimates from state data (last reviewed 2026-09-16). Local/county taxes can shift the total slightly, and some registration fees vary by vehicle weight or value — the dealer's written itemized breakdown is the real number. Ask for it line-by-line before you sign.
The doc fee isn't where deals go wrong — dealer add-ons are.
Pull the original window sticker for any VIN to see exactly what the factory shipped — so every “optional equipment” line on your quote has to justify itself.

Negotiate the out-the-door number, not the monthly payment. Ask every dealer for a written, itemized OTD quote on the same vehicle, then compare line by line: the tax, title, and registration lines should match this calculator within a few dollars — they are state-set. The lines that differ between dealers are the doc fee and the add-ons, and those are exactly the lines you push on. In doc-fee-cap states, a fee above the cap is simply wrong; in uncapped states, the doc fee is dealer profit with a negotiable sticker on it.
Frequently asked questions
What is an out-the-door price?
The out-the-door (OTD) price is the total you actually pay to drive off: the negotiated vehicle price plus sales tax, title fee, registration, the dealer doc fee, and any add-ons. It is the only number worth negotiating, because dealers can give on the price and take it back in the fees.
How do I calculate the out-the-door price of a car?
Start with the negotiated vehicle price. Add your state’s vehicle sales tax (applied to the price minus your trade-in in most states), the state title fee, registration, and the dealer’s doc fee. Some states cap the doc fee by statute; where there is no cap, it is dealer-set and negotiable. This calculator itemizes each line for all 50 states and D.C.
Does a trade-in reduce the sales tax?
In most states, yes — tax applies to the price minus the trade-in allowance. A handful of states (including California, Virginia, Kentucky, Hawaii, Maryland, and D.C.) give no trade-in credit and tax the full price. The calculator applies each state’s rule automatically.
Which fees on a car purchase are negotiable?
Tax, title, and registration are set by the state — nobody is negotiating those. The doc fee is dealer profit in uncapped states, and dealer add-ons (protection packages, nitrogen, etching) are the most negotiable lines on the sheet. Compare the quote against the factory window sticker to see what the car actually shipped with.
Why is my dealer quote higher than this estimate?
Local and county taxes can add to the state rate, registration can vary by vehicle weight or value, and many quotes include dealer add-ons that are not state fees at all. Ask for a written itemized breakdown and compare it line by line against this build-up — anything that is not tax, title, registration, or a capped doc fee is a conversation.
