The only number that matters at the desk is this one: negotiate out-the-door, never monthly payment - a payment fits any ripoff if the term stretches. Two honesty notes on the tax math: most states tax the price after the trade-in credit, some tax the full price before it, and rebates are taxed in some states and exempt in others - your state DMV publishes which, and this calculator runs the common case (trade credited, rebate subtracted at the end). On a used car, the FTC Used Car Rule (16 CFR 455) requires a Buyers Guide on every vehicle in the row - the document where the dealer's cash price and terms meet your out-the-door number.
Own the number after the sale: the sales tax calculator for any state rate, car depreciation for what it loses leaving the lot, the insurance renewal calculator before you sign the finance office's add-ons, and fuel cost for the years after.

Use this before or at the desk: enter the price you agreed on the car, the destination and doc fees on the buyer's order, your sales tax rate, and any trade-in or rebate - the calculator produces the out-the-door total, the only number a deal should be judged by.

Sticker price is not the argument; the paperwork is where deals change. Tax rides on the price (most states credit your trade first), destination is fixed by the maker, doc fees are capped by some states and invented by others, and the finance office adds etch and nitrogen if you let them. The out-the-door number folds all of it into one line you can compare across dealers - and across a payment offer, by dividing it by the term yourself.

How to use

  1. Enter the agreed vehicle price - the number on the line that says selling price, not MSRP.
  2. Add destination plus the dealer doc fee from the buyer's order, and set your sales tax rate with the slider.
  3. Enter trade-in credit and rebates, then negotiate against the out-the-door total - never against a monthly payment.
Good to know โ€” The gap between sticker and out-the-door is where car deals are actually priced: 6% sales tax on a $28,000 car adds $1,680, destination and doc fees add four figures more, and finance-office add-ons can quietly exceed the destination charge. Federal rulemaking polices the disclosure side - the FTC's Used Car Rule (16 CFR 455) mandates the Buyers Guide on every used vehicle in the row - but the arithmetic side has no regulator, which is why the out-the-door total, computed before you sit down, is the buyer's only fixed point.
Quick reference โ€” Email three dealers the same sentence: "what is your out-the-door price on this stock number, including tax, title and doc?" The spread in the replies is your negotiating leverage - and any reply that only quotes a monthly payment has told you something too.

Frequently asked questions

What does out-the-door price include?

Everything you will actually pay to drive out: the agreed vehicle price, sales tax, destination charge, dealer doc fee, and title and registration, minus trade-in credit and rebates. A dealer quoting "out the door" has committed to the whole structure - which is exactly why you ask for it in writing before the finance office.

Is sales tax charged on the trade-in value?

In most states, no - the tax applies to the difference between the price and your trade-in credit, which is one of the quiet advantages of trading in. Some states tax the full price regardless, and a few treat rebates differently too. Your state DMV publishes the rule; this calculator runs the common case - trade credited, rebate subtracted after tax.

What dealer fees are legitimate?

Destination charge (set by the manufacturer, on the window sticker), title and registration (government lines), and a doc fee within your state's cap - several states cap it hard, others barely. What is never legitimate: etch, nitrogen, fabric protection, VIN etching logos - hundreds of dollars of margin for things your new car already has or does not need.

Why do dealers want to talk monthly payment?

Because a payment can absorb any number: stretch the term, adjust the rate, roll the add-ons in, and the monthly stays the same while the total balloons. The defense is to negotiate the out-the-door total first and only then discuss financing - on this calculator's number, not theirs.

Does the out-the-door rule apply to used cars?

Yes - and used-car buyers get one extra protection: the FTC's Used Car Rule requires every dealer to display a Buyers Guide on each vehicle, stating the cash price and the terms of the deal. The guide is the legal mirror of the out-the-door math; if the contract and the guide disagree, the guide is supposed to win.
