Understand your written dealer quote
Manually enter a Texas dealer worksheet or buyer’s order to compare its amounts with an independent estimate of taxes, government fees and the purchase total. Dealer terminology varies, and not every charge can be classified. Results are informational estimates, not legal advice.
Manual entry for Texas dealer purchases. Keep the independently modeled deal separate from the amounts on the written quote. Leave missing worksheet amounts blank; enter 0 only when confirmed.
Estimate date: 2026-10-07. Change it in Advanced options.
Enter the deal details, then the dealer’s quoted total or its vehicle price and available worksheet items. Choose whether the total includes trade-in credit. Your comparison will appear here; blank worksheet lines remain “Not provided.”
Informational comparison, not legal advice. Dealer terminology and circumstances vary; a difference does not establish an error or determine whether a charge is lawful. Request clarification and verify important amounts with appropriate authorities or professionals.
A dealer may provide a worksheet, purchase proposal, buyer’s order or written quote showing a vehicle price, credits, products, taxes, fees and a total. Labels and groupings vary. Use the purchase transaction figures, rather than a monthly payment or amount financed, and enter each charge only once.
CarCostProof independently models applicable Texas taxes, title and registration-related government fees using the deal and vehicle details. Documentary fees and add-ons are shown separately as dealer-controlled amounts. That category does not imply that a charge is improper or establish whether it is optional.
Different selling prices, credits, products, vehicle classifications, local processing circumstances, effective dates or data-entry errors can explain differences. A combined fee may not cover the same items as the calculator’s group. Blank fields and custom charges also limit a line-by-line comparison.
Request an itemized written explanation of unfamiliar charges. Ask which authority imposes a government-related fee, how vehicle tax was calculated, what an add-on includes and whether it is optional. The checker generates questions from your entries without drawing legal conclusions.
No. A difference is a reason to review details, not automatic proof of error or wrongdoing. This tool does not determine whether a fee is lawful. Verify government charges with the appropriate authorities and seek qualified advice when needed.
Use the Texas Out-the-Door Car Price Calculator to build a dealer purchase estimate. For a focused calculation, use the vehicle sales tax calculator or the full tax, title and registration calculator.
It is a written proposal or breakdown of a vehicle deal. It can list selling price, add-ons, taxes, fees, credits and a transaction total. Terminology and scope vary between dealerships.
It is a dealer document describing the proposed vehicle purchase and its charges. Review the actual document’s terms and itemization; this checker compares entered numbers rather than interpreting a contract.
Enter the deal details for an independent estimate, then enter the quote’s total and any equivalent itemized amounts. Specify whether the quoted total already includes trade-in credit. The checker shows exact differences and missing or unclassified amounts.
The verified engine can include motor-vehicle tax, title, registration, TexasSure, county/local fees, inspection replacement, applicable emissions-related or EV fees, and processing and handling. Which lines apply depends on the county, date and vehicle.
No. The separately stated documentary fee is shown as a dealer-controlled amount. This tool does not supply an official target doc fee, and the verified motor-vehicle tax calculation excludes it from taxable consideration.
The quote may use different transaction inputs or contain products, custom charges or costs outside the model. Missing entered items can also prevent reconciliation. Ask for an itemized explanation; a difference is not proof of an incorrect quote.
Supported taxable accessories or attachments entered separately in Deal details affect the verified taxable consideration. A custom charge or user-selected category does not automatically establish its tax treatment or change the independent expected tax.
No. It is an informational numerical comparison, not a legal determination. It distinguishes modeled government amounts, dealer-controlled amounts and charges without a matched target.
No. Interest, APR, loan terms, payments, financing products, loan payoff and negative equity are outside this purchase-transaction comparison. Do not compare an amount-financed figure with an out-the-door purchase total.
No. This version uses manual entry only. Enter the numbers from the written quote; no image, PDF or document upload is available.
