The out-the-door price is the full transaction price — vehicle price, tax, and fees — before considering how you pay for it. Trade-in and down payment reduce what you owe today, not the price itself. Manufacturer rebates are taxed in most states (the toggle defaults to "No"); trade-ins get a tax credit in most states (the toggle defaults to "Yes") — check your state if you're close to the line. The monthly payment shown is an estimate only; for a full amortization schedule and negative-equity handling, use the Auto Loan Calculator.
See the real total price of a car — negotiated price, rebates, sales tax, and fees — before financing ever enters the picture.
How to use this calculator
- Enter the negotiated vehicle price — before tax, and separate from any monthly payment a dealer quotes.
- Add any rebates and your trade-in value, and set whether each reduces the taxable amount in your state.
- Set your sales tax rate, doc fee, and title & registration fees.
- Add your down payment, then choose cash or financing. If financing, add the APR and term for an estimated payment.
The formula
Out-the-door price = (Price − Rebates) + Sales tax + Fees
Amount due = Out-the-door price − Trade-in value − Down payment · Sales tax base = Price − (Rebate credit, if your state gives one) − (Trade-in credit, if your state gives one)
Worked example — $32,000 car with a rebate and a trade-in
$32,000 price, $1,500 manufacturer rebate (taxed — most states), $6,000 trade-in (tax-credited — most states), 7% sales tax, $500 doc fee, $150 title/registration, $2,000 down, financed at 6.5% for 60 months.
- Price after rebate: 32,000 − 1,500 = $30,500
- Taxable amount: 32,000 − 6,000 (trade credit; rebate is still taxed) = $26,000
- Sales tax: 7% of 26,000 = $1,820
- Fees: 500 + 150 = $650
- Out-the-door price: 30,500 + 1,820 + 650 = $32,970
- Amount due: 32,970 − 6,000 − 2,000 = $24,970
- Estimated monthly payment: ≈$489
Notice the rebate is subtracted from the price but not from the taxable amount — that's the default in most states, and it's the detail a dealer's payment quote is least likely to spell out.
Why "out-the-door," not "monthly payment"
A monthly payment is a function of price, term, and rate — any one of the three can be adjusted to make the payment look attractive while the total cost gets worse. Stretch the term and the payment drops while total interest climbs. Quote 0% financing and the price may quietly rise to offset it. The out-the-door price collapses all of that into one number that doesn't depend on how you finance it, which is why it's the number worth negotiating before a payment is ever discussed.
Once you have an out-the-door price you're comfortable with, financing is a separate, simpler conversation: compare your own bank or credit union's rate against the dealer's offer on that same fixed price, not a moving one.
Common mistakes to avoid
- Negotiating the payment instead of the price. Fix the out-the-door price first; discuss term and rate after.
- Assuming a rebate lowers your tax bill. In most states it doesn't — you're taxed on the pre-rebate price.
- Treating trade-in value as cash toward the price. It reduces what you owe, not the out-the-door price itself, and if you still owe more than it's worth, see the Auto Loan Calculator for how that negative equity is handled.
- Skipping doc and title fees when comparing dealers. An unusually low advertised price with a high doc fee can land at the same out-the-door total as a straightforward one.
- Confusing MSRP with the price you should pay. MSRP is a starting point for negotiation, not the out-the-door price — this calculator uses whatever price you've actually agreed to.
How we calculate this
Out-the-door price = (vehicle price − rebates) + sales tax + fees. Sales tax is calculated on the vehicle price, adjusted by whichever credits apply: most US states exclude a trade-in's value from the taxable amount but tax the full pre-rebate price, which is why the two toggles default differently. Fees are the dealer documentation fee plus government title and registration charges. The amount due is the out-the-door price minus trade-in value and down payment, floored at zero. When financing, the estimated monthly payment uses the standard fully-amortizing payment formula on that amount due — it does not model negative equity on a trade; see the Auto Loan Calculator for that.

Frequently asked questions
What is the out-the-door price?
The full transaction price for the car: the negotiated price, minus any rebates, plus sales tax and dealer/government fees. It is the total you are on the hook for before down payment, trade-in, or financing enter the picture — the number a dealer's advertised or monthly-payment quote often hides.
Why does a dealer quote a monthly payment instead of the out-the-door price?
A monthly payment can be made to hit almost any number by stretching the loan term, so it says very little about what the car actually costs. Negotiate the out-the-door price first, then discuss financing — a low payment on a long term or an inflated price is the single most common way buyers overpay.
Are manufacturer rebates taxed?
In most US states, yes — sales tax is calculated on the price before the rebate is applied, so a $4,000 rebate on a $37,000 truck still means tax on $37,000. Roughly 20 states (including Arizona, Texas, and Pennsylvania) tax the post-rebate price instead. The calculator's toggle defaults to "No" (taxed) since that's the more common rule — check your state if the numbers are close.
Does a trade-in reduce my sales tax?
In most US states, yes — you're taxed on the price minus the trade-in allowance, not the full price. Trading a car worth $6,000 against a $32,000 purchase means tax on $26,000 instead of $32,000, which at 7% saves $420. A handful of states, including California, tax the full price regardless of trade-in.
What fees should I expect beyond tax?
A dealer documentation ("doc") fee — capped by law in some states, unrestricted in others, typically $100–$700 — plus government title and registration fees set by your DMV, which aren't negotiable. Anything beyond that (extended warranties, paint protection, VIN etching) is an add-on, not a required fee, and worth declining or pricing separately.
Is the out-the-door price the same as the amount I finance?
No. The out-the-door price is the total cost of the car regardless of how you pay. The amount you finance (or pay in cash) is the out-the-door price minus your trade-in value and down payment. This calculator shows both, since it's easy to negotiate a decent out-the-door price and still finance more than expected because a trade-in or down payment was smaller than assumed.
How is the estimated monthly payment calculated?
The standard fully-amortizing loan payment formula, applied to the amount due after trade-in and down payment, at your entered APR and term. It doesn't account for negative equity on a trade (where you owe more than the trade is worth) — use the Auto Loan Calculator for that scenario and a full year-by-year schedule.
