Out the Door Price Formula
The out the door price (OTD) is the total amount you pay to drive a car off the dealer lot. Unlike MSRP or the advertised price, OTD includes every cost — taxes, fees, and add-ons. Here is the formula:
OTD Price =
Selling Price + Sales Tax + Registration + Title + Doc Fee + Add-Ons - Trade-In - Rebates
In most states, sales tax is calculated on the selling price minus your trade-in value. Trading in a vehicle then reduces both the price and the tax you owe, so the total savings are larger than the trade-in value alone. Six jurisdictions are the exception and tax the full price with no trade-in credit: California, Hawaii, Kentucky, Maryland, Virginia, and Washington DC.
Out the Door Price Calculator by State
Vehicle tax rates, trade-in credit rules, doc fee caps, and registration fees are set state by state. Pick your state for a calculator pre-loaded with its 2026 rates, a worked $35,000 example, and the state's fee rules:
Percentages are the statewide vehicle tax rate; local city/county taxes may add more in some states. Five states charge no vehicle sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon.
How to Use This Calculator
Enter the negotiated selling price
Use the price you've negotiated or expect to pay — not the MSRP sticker price. If you haven't negotiated yet, use MSRP as a starting point.
Select your state
The statewide vehicle tax rate, typical doc fee, and registration & title fees auto-fill from state DMV data. Add your city or county tax rate if your state has local add-ons.
Check the doc fee
Some states cap doc fees by law (California at $85, New York at $175); in uncapped states dealers commonly charge $500-$1,000. The field is editable — use the number from your quote.
Add dealer add-ons (if any)
Paint protection ($399-$999), nitrogen tire fill ($99-$299), VIN etching ($149-$299) — these are often negotiable or removable.
Include trade-in and rebates
Your trade-in value reduces the taxable amount in most states. Manufacturer rebates reduce the final price (but usually not the taxable amount).
Pro Tips for Getting the Best OTD Price
- • Always ask the dealer for an itemized out the door quote in writing before agreeing to anything
- • Question any add-ons you didn't request — they can almost always be removed
- • Compare your calculated OTD to what buyers actually paid for the same model
- • Get OTD quotes from 3-5 dealers and negotiate using the lowest as leverage
- • Negotiate the selling price first, then ask for the OTD — don't let the dealer bundle everything
- • Check if your state offers a trade-in tax credit before deciding how to sell your current vehicle
What's Included in Out the Door Price?
Selling Price
The negotiated vehicle price, also called the purchase price. It may be above, at, or below MSRP depending on supply and demand for that vehicle.
Sales Tax
State and local vehicle tax calculated on the selling price (minus trade-in in most states). Statewide rates range from 0% (Alaska, Delaware, Montana, New Hampshire, Oregon) to 7%+, and local add-ons push some cities over 10%. This is the largest non-price component of OTD.
Registration & Title Fees
Government fees to register the vehicle in your name and issue a title. These are set by your state and are not negotiable — typically $50-$500 depending on the state and, in some states, the vehicle's value or weight.
Documentation Fee (Doc Fee)
The dealer's charge for processing paperwork. Roughly 20 states cap it by law (California at $85, New York at $175, Minnesota at $350); in uncapped states it commonly runs $500-$1,000. Set by the dealer and sometimes negotiable.
Dealer Add-Ons
Optional (and sometimes pre-installed) items like paint protection film, ceramic coating, nitrogen tire fill, VIN etching, and wheel locks. Almost always negotiable and often overpriced.
What is NOT included in OTD price
Out the door price does not include monthly payments, interest charges, or extended warranty costs. If you are financing, your total cost over the life of the loan will be higher than OTD due to interest. OTD is the amount you owe at the time of purchase, regardless of how you pay.
Frequently Asked Questions
What is out the door price?
Out the door price (OTD) is the total amount you pay to drive a vehicle off the dealer lot. It includes the negotiated selling price plus sales tax, registration and title fees, documentation fees, and any dealer add-ons. OTD price is always higher than the sticker price or advertised price because it includes all taxes and fees.
What is the formula for out the door price?
The out the door price formula is: OTD Price = Selling Price + Sales Tax + Registration & Title Fees + Doc Fee + Dealer Add-Ons - Trade-In Value - Rebates. Sales tax is calculated on the selling price minus trade-in value in most states.
How much do taxes and fees add to a car price?
Taxes and fees typically add 8% to 12% on top of the selling price, depending on your state and local tax rates. On a $35,000 car, expect to pay roughly $2,800 to $4,200 in taxes and fees. States with no sales tax on vehicles (Alaska, Delaware, Montana, New Hampshire, Oregon) will be on the lower end — though Delaware charges a 5.25% document fee instead.
Is out the door price negotiable?
The selling price and dealer add-ons within the OTD are negotiable. Sales tax and government registration fees are not negotiable. The documentation fee is set by the dealer and sometimes negotiable. You should always ask the dealer to remove unnecessary add-ons like paint protection, nitrogen tire fill, or VIN etching.
Does out the door price include tax?
Yes, out the door price includes all applicable sales taxes. It is the final, total amount you pay — there should be no additional charges beyond the OTD price. If a dealer quotes an OTD price and then adds more fees at signing, that is a red flag.
What is the difference between MSRP and out the door price?
MSRP (Manufacturer's Suggested Retail Price) is the sticker price set by the manufacturer and does not include taxes, registration, or dealer fees. Out the door price is the total you actually pay, including all taxes and fees. OTD is typically 8-12% higher than MSRP, though dealer discounts can offset some of that difference.
Which states have no sales tax on cars?
Five states have no state sales tax on vehicle purchases: Alaska, Delaware, Montana, New Hampshire, and Oregon. Watch the substitutes, though: Delaware charges a 5.25% document fee on the vehicle price, Oregon adds a 0.5% privilege tax on new vehicles, and some Alaska boroughs levy a local sales tax.
Does trade-in reduce sales tax?
In most states, yes. Your trade-in value reduces the taxable amount. For example, if you buy a $35,000 car and trade in a vehicle worth $10,000, you only pay sales tax on $25,000. This trade-in tax credit can save you $500 to $1,000 or more. However, a few states tax the full purchase price with no trade-in credit: California, Hawaii, Kentucky, Maryland, Virginia, and Washington DC.
Methodology & Sources
Tax rates, trade-in credit rules, doc fee caps, and title & registration fees come from each state's DMV, Department of Revenue, or motor-vehicle statutes, audited state by state. Data last reviewed .
Estimates use the statewide vehicle tax rate; local city/county taxes vary by address and can be added in the calculator. Doc fees default to the state cap (up to $499) or a $499 typical figure where uncapped — always replace defaults with the numbers on your written dealer quote. Per-state details and official sources are on each state calculator page and the matching state fee reference.
