What Is an Out-the-Door Price?
The out-the-door (OTD) price is the total you pay to drive a car off the lot: the negotiated price plus sales tax, title, registration, doc fees and add-ons, minus rebates. For a $32,000 car with a $8,000 trade-in, $1,000 rebate, 7% tax and $724 of fees, the OTD price is $33,404.00. Negotiating the OTD number stops fees from being added back after you agree on a price.
Out-the-Door Price Formula
Taxable price
Taxable = Price + Add-ons − Trade-in credit$32,000 − $8,000 = $24,000 (rebates are usually still taxed).
Out-the-door price
OTD = Price + Add-ons + Tax + Fees − Rebates$32,000 + $1,680.00 + $724 − $1,000 = $33,404.00.
Trade-in equity
Equity = Trade-in value − Loan owedNegative equity is added to what you finance.
Amount to finance
Loan = OTD − Equity − Down payment$33,404.00 − $8,000 − $3,000 = $22,404.00.
Next step: plug the amount to finance into the Auto Loan Calculator to see the monthly payment and total interest.
Every Line in an Out-the-Door Price
| Line item | What it is | Usually taxed? |
|---|---|---|
| Negotiated vehicle price | The price you agree with the dealer, before anything else is added | Yes |
| Sales tax (or motor vehicle tax) | State and local tax on the taxable price; some states use a separate vehicle tax rate | — |
| Documentation (doc) fee | Dealer’s charge for paperwork; amounts vary widely and some states cap them | Varies by state |
| Title fee | State fee to put the title in your name | No |
| Registration & plates | State fee to register the vehicle; often based on weight, value or age | No |
| Dealer add-ons | Extras such as paint protection, nitrogen tires, VIN etching or service contracts | Usually yes |
| Destination charge | Shipping from the factory — normally already in the window-sticker price | Yes |
| Rebates & incentives | Manufacturer cash back that lowers what you pay | Often taxed before the rebate |
| Trade-in credit | Value of your old car; in most states it also lowers the taxable price | Reduces tax in most states |
How a Trade-In Lowers Your Sales Tax
In most states you pay tax only on the difference between the new car’s price and your trade-in. At 7%, an $8,000 trade-in saves $560 in tax compared with selling the old car privately for the same amount. A few states, including California, tax the full price regardless of the trade-in, so a private sale can come out ahead there.
| Trade-in value | Tax saved at 6% | Tax saved at 7% | Tax saved at 9% |
|---|---|---|---|
| $3,000 | $180.00 | $210.00 | $270.00 |
| $5,000 | $300.00 | $350.00 | $450.00 |
| $8,000 | $480.00 | $560.00 | $720.00 |
| $12,000 | $720.00 | $840.00 | $1,080.00 |
| $20,000 | $1,200.00 | $1,400.00 | $1,800.00 |
Vehicle tax rules vary: some states use a separate motor vehicle tax (for example, North Carolina charges a 3% highway use tax instead of sales tax). Check your state DMV or revenue department.
5 Out-the-Door Negotiation Tips
- Ask for a written OTD quote from several dealers before visiting, so fees can’t appear at signing.
- Negotiate the total, not the monthly payment. A longer loan can hide a higher price.
- Question every add-on. Paint protection, etching and nitrogen fills are often optional.
- Separate the trade-in. Get an outside offer first so you know its real value.
- Compare financing. A pre-approved loan gives you a benchmark against dealer financing.

Out the Door Price Calculator FAQs
It is the total cost to buy a car and drive it away: the negotiated price plus sales tax, title, registration, documentation and other fees, and any add-ons, minus rebates.
Add the negotiated price, add-ons, sales tax and fees, then subtract rebates. Tax is usually charged on the price minus your trade-in value. The calculator shows each line on a deal sheet.

Common fees are sales tax, title, registration and plates, and a dealer documentation fee. Destination is usually already in the sticker price. Be cautious of extra add-ons you did not ask for.

At a 7% rate with an $8,000 trade-in credit, tax is $1,680. Without a trade-in it would be $2,240. Your rate depends on your state and local area.
