Compare Dealer Quotes by Out-the-Door Price
Put up to three written offers into the same structure so a low advertised price, monthly payment or inflated trade allowance does not hide the more expensive deal.
Compare total price, not payment.
Add dealer fees, add-ons and government charges exactly as quoted.
Government amounts are compared as entered. Run the applicable state calculator separately to audit taxes and fees.
Compare the same categories across every quote
Dealer worksheets often use different labels and layouts. One may combine documentation and electronic filing charges, while another may place accessories or protection products inside the vehicle price. Enter each amount in the closest matching category rather than comparing only the printed subtotal.
- Vehicle selling price after the negotiated discount.
- Dealer-controlled documentation or processing fees.
- Optional or dealer-installed products and accessories.
- Sales tax, title, registration and other government charges.
- Rebates, cash down payment and gross trade allowance.
- Trade payoff so equity is not confused with tax treatment.
Use this comparison order
- Confirm that every quote describes the same vehicle and trim.
- Compare the complete out-the-door purchase price.
- Inspect dealer fees and add-ons that create the difference.
- Review gross trade allowance and payoff as separate numbers.
- Compare APR, term and total interest only after price.
Why a larger trade allowance can still be a worse deal
A dealer can raise the trade allowance while also raising the replacement vehicle price or adding products. The customer sees a stronger trade number, but the net transaction can remain unchanged or become more expensive. Compare the replacement vehicle price, gross trade allowance and payoff independently.
Verify government charges outside the comparison
This page compares the taxes and registration amounts entered from each quote; it does not automatically decide that a government line is correct. Check the appropriate state calculator and the official source registry before challenging a figure.
Normalize the vehicle and incentive eligibility first
A fair comparison starts with the same vehicle. Match VIN when possible, or at minimum match model year, trim, drivetrain and major factory options. Then check whether each discount is actually available to you. A quote that includes a military, loyalty, conquest, college-graduate or captive-finance incentive you cannot claim is not a lower real-world quote.
If one dealer has not identified the VIN, ask whether the quoted vehicle is physically in stock and whether destination or transport is already included. Mark any conditional discount separately instead of subtracting it from every quote automatically.
Translate different dealer labels into the same categories
Dealers can use different names for similar charges: document fee, processing fee, dealer service fee, electronic filing, reconditioning, protection package, certification fee or market adjustment. The label alone does not tell you whether the charge is a government fee, a dealer-controlled fee or a product. Reclassify the line before comparing totals.
If a quote contains one large line such as “taxes and fees,” ask for an itemized version. You cannot meaningfully verify title, registration, dealer fees or add-ons while they are bundled into one unexplained number.
Compare the transaction before the financing presentation
Down payment changes how much you finance, not what the vehicle purchase itself costs. A longer term can also lower the monthly payment while increasing total interest. Record selling price, dealer-controlled charges, add-ons, tax and government fees first; then compare APR, term, lender fees and total finance cost as a separate decision.
Save the final written quote you are actually choosing
Once one offer wins, keep the written quote and compare it with the buyer's order or purchase agreement before signing. Recheck VIN, selling price, rebates, dealer charges, add-ons, trade allowance, payoff, taxes and registration. A comparison tool is most useful when the “winning” numbers survive into the final paperwork.
Worked example: the lower advertised price loses
Dealer A sells the vehicle for $28,500 but adds $2,200 of dealer fees and products. Dealer B sells it for $29,400 with $600 of dealer-controlled charges. Before tax and government fees, Dealer A is $30,700 while Dealer B is $30,000. The $900 lower selling price is not the lower deal once the quote is normalized.
Do not let financing rewrite the purchase comparison
Compare price and OTD first. APR, loan term and down payment belong in the financing comparison after the purchase totals are normalized. CFPB consumer guidance notes that the interest rate offered by a dealer can be negotiated, and FTC guidance recommends getting written OTD prices so competing offers can be compared on the same basis.

Frequently asked questions
Should I compare monthly payments or OTD prices?
Compare the out-the-door price first because loan term, APR and down payment can make a more expensive deal appear cheaper each month. Review financing only after the purchase totals are normalized.
How should I enter a trade-in with a loan payoff?
Enter the dealer's gross trade allowance and the outstanding payoff separately. The difference is trade equity, while the gross allowance may affect the taxable amount under the applicable state rules.
Does the lowest selling price always mean the best quote?
No. A lower advertised or negotiated price can be offset by higher dealer fees, mandatory add-ons, fewer rebates or a weaker trade allowance. Compare the complete transaction structure.
Can this tool verify taxes and registration charges?
The comparison records the figures shown on each quote. Use the detailed state calculator for Florida, Texas, Washington, California, Georgia, North Carolina, Illinois, New York or Tennessee—or the national custom-rate calculator—to test those charges separately.
