A down payment and trade-in credit reduce the cash you must bring or the amount you finance; they do not change the underlying OTD purchase price. Loan amount, term, and APR affect financing. Interest paid over time is generally not part of a vehicle's quoted OTD price, so evaluate financing separately.
Add taxes, title, registration, and dealer fees.
Use market value, condition, repairs, and history.
Five car-price terms that are not interchangeable
| Term | Meaning | What to remember |
|---|---|---|
| Advertised price | The price in an ad. | It may depend on discounts or exclude charges. |
| Selling price | The negotiated vehicle price. | It starts the OTD calculation. |
| Out-the-door price | Selling price plus taxes, government charges, mandatory dealer fees, and accepted add-ons. | Use it to compare purchase offers. |
| Amount financed | The amount borrowed after down payment, trade-in credit, and other credits, including financed products or charges. | It can differ from OTD price. |
| Total loan cost | Principal and interest paid over the loan, plus applicable finance charges. | A longer term can lower payments but raise total cost. |
Worked out-the-door price example
Suppose you negotiate an $18,000 selling price, sales tax is 6%, the documentation fee is $260, and title and registration cost $250. Assume no add-ons and that tax applies only to the vehicle price.
- Sales tax: $18,000 × 6% = $1,080
- OTD price: $18,000 + $1,080 + $260 + $250 = $19,590
A $2,000 down payment would not change that $19,590 underlying OTD price; it changes how the purchase is paid. Actual tax rules vary.
Common charges on a buyer's order
A buyer's order may show selling price, sales or use tax, title, registration or license, temporary-tag, documentation or processing, electronic-filing, delivery or destination, inspection or emissions charges, trade-in credit, deposit, and optional products. Read every line and check the total.
Government charges
Taxes, title, registration, and similar state or local charges are generally mandatory. Ask which agency requires an unfamiliar charge and verify it with that agency.
Dealer fees
Documentation, processing, filing, and other dealer-imposed fees may be mandatory under dealer policy, limited by local law, or presented differently. Do not assume every dealer fee is illegal or negotiable; question unexplained charges and compare totals.
Optional add-ons
Service contracts, GAP coverage, VIN etching, paint protection, fabric protection, and tire/wheel packages are not government charges. Review the price and terms. You may decline optional add-ons you do not want.
Accepted products count
An add-on you accept belongs in OTD price even when rolled into a loan. Check whether it is taxable and understand cancellation terms before signing.
Request the itemized OTD quote before you visit
Use the VIN or stock number and request an itemized OTD quote in writing before visiting. The FTC recommends obtaining the complete OTD price in writing to compare offers, confirm discount conditions, and detect extra charges or unwanted add-ons.

How to compare quotes
- Request quotes for the same or genuinely comparable vehicles and the same registration ZIP code.
- List selling price, discount conditions, taxes, government charges, dealer fees, and add-ons side by side.
- Check that no quote silently assumes a trade-in, down payment, special eligibility, or dealer financing.
- Remove optional products you do not want, then compare OTD totals—not monthly payments. Request corrections in writing.
- After selecting the purchase offer, separately compare APR, term, amount financed, payment, finance charge, and total of payments.
Warning signs
- Monthly-payment-only negotiation: a changed term, rate, price, or add-on can hide behind an affordable payment.
- Unexplained fees: ask what each charge covers and who requires it.
- Conditional discounts: verify trade-in, loyalty, military, college, or other requirements.
- Required dealer financing: ask whether outside financing or cash changes the price, then compare loans separately.
- Unwanted add-ons: ask that optional items be removed and decline products you do not want.
- A changed price on arrival: compare the written quote line by line before signing.
