Out-the-Door Price Worksheet

$9.99

One number, itemised, with the taxable amount working your state's trade-in rule live rather than leaving it to you to remember: four states with a sales tax credit nothing against a trade-in, and Ohio credits it against a new vehicle only. Checks a documentation fee against the nine statutory caps this site has confirmed, and is explicit that the other 41 states are unresearched rather than uncapped. Prices the F&I office as the optional extra it is, and adds the trade-in payoff back into the amount financed — because negative equity does not disappear when you trade the car, it moves into the new loan and accrues interest.

Out-the-Door Price Worksheet
One number, itemised. Fill the blue cells and the taxable amount works your state's trade-in rule for you — including the four states that give no credit at all and Ohio's new-vehicles-only version. Anything you do not know yet, leave at zero and ask for it in writing before you sign.
Part 1 — The car
Vehicle / stock number2026 Sedan / STK-4417
DealerExample Motors
Advertised price38000What the listing says. This is not the price.
Negotiated vehicle price38000What you actually agreed, before anything else.
New or used? 1 = new, 0 = used1Only matters in a state that restricts the trade-in credit to new vehicles. Ohio does; the row below handles it.
Part 2 — Your state's rules
Look these up once, from your state's own department of revenue or motor vehicles, and write them here. A salesperson is not the source for any of them.
State sales tax rate (%)5.75The STATE rate. If your county or city adds one, include it here and note that some states charge it where you live rather than where you buy.
Does the state credit a trade-in? 1 = yes, 0 = no1NO in California, Hawaii, Oklahoma and Virginia — those four charge tax on the full price however large your trade-in. Five more give no credit but have a 0% rate, so it costs nothing.
Credit restricted to NEW vehicles? 1 = yes, 0 = no1Ohio is the case this exists for. Set to 1 and buy used, and the credit disappears.
Hard dollar cap on the tax, if any0South Carolina caps its Infrastructure Maintenance Fee at $500. Leave at 0 for no cap. Yellow because almost nobody has one and a wrong value here quietly understates your tax.
Statutory doc fee cap, if your state has one0Nine confirmed: WA $200, CA $260, MI $280, MN $350, LA $425, PA $490, MO $620.79, MD $800; CT confirmed none. The other 41 are unresearched here, which is NOT the same as uncapped — check your own state. Leave at 0 if unknown.
Part 3 — The trade-in
Trade-in allowance offered12000
Payoff still owed on it4000From a ten-day payoff quote, not from a statement. The statement balance is out of date the day it prints.
Your equity in itƒxNegative means you are underwater, and the difference gets financed into the new loan. Part 7 prices that.
Independent valuation — source 111500Two sources, before you hear the dealer's number. An allowance is only generous relative to something.
Independent valuation — source 212400
Part 4 — What tax is actually charged on
Trade-in credit you actually getƒxZero if your state gives no credit, zero if the credit is new-only and you are buying used, otherwise the allowance (capped at the price).
TAXABLE AMOUNTƒxCheck the dealer's tax line is computed on THIS figure. It is the single most valuable check on the page.
Sales tax before any capƒx
Sales tax owedƒx
Extra tax caused by no trade-in creditƒxWhat the trade-in credit would have saved you, and did not. Statute, not negotiation — but it changes whether trading in beats selling privately.
Part 5 — The fees, line by line
Every line here should appear on an itemised quote. A fee you cannot get a name for is a fee to question.
Documentation fee250
Over your state's cap byƒxAsk about it as a question — "my understanding is the cap is X, can you show me where this comes from?" — not as an accusation. In a capped state it is usually corrected without argument.
Title fee15Your DMV publishes it. Ranges from a few dollars to a couple of hundred.
Registration235Often a function of weight or value rather than a flat figure.
Destination / freight0A real manufacturer charge, on the window sticker.
Dealer prep0Frequently the same work as destination, billed twice. Negotiable.
Advertising fee0Ask to see it on the invoice. If it is not there it is not a pass-through.
Other fee — name it: ____________0
Other fee — name it: ____________0
Total feesƒx
Part 6 — The out-the-door number
OUT THE DOORƒxVehicle price plus tax plus every fee. This is the only figure worth comparing between dealers.
Gap over the advertised priceƒx
As a share of the advertised priceƒx
Part 7 — Financing
Cash down payment0
Rebate applied0If you took a rebate instead of promotional financing. Note some states tax the price before the rebate.
Amount financedƒxOut the door, less cash and rebate, less the trade allowance, PLUS whatever is still owed on the trade. That last term is the negative equity moving into this loan.
Interest rate (%)6.9From a pre-approval you already hold, ideally. Then let the dealer try to beat it.
Term (months)60The shortest you can genuinely sustain. A longer term lowers the payment and raises the cost, and keeps you underwater longer.
Monthly paymentƒx
