Out the Door Price Calculator adding state sales tax, doc fee, title and registration to a negotiated car price, minus rebates and trade-in equity, or working back from any budget.
Out the door is the price plus tax and fees, less rebates and your trade-in equity. It is the only number worth comparing between dealers.
Tax, Fees and Rebates
Picking a state fills the statewide rate, a typical doc fee and title and registration. Add your county or city rate, then replace any figure with the dealer’s quote.
Financing the Balance
Only used for the payment estimate. Agree the out-the-door price first, then talk about the loan.

Out the Door Price Calculator for Any State
The Out the Door Price Calculator adds sales tax, the dealer doc fee, title and registration and any add-ons to a negotiated price, then takes off rebates and your trade-in equity. The result is the one number worth comparing between dealers. It also runs in reverse, finding the highest vehicle price that fits an out-the-door budget.
Pick your state and it fills in the statewide tax rate, a typical doc fee and title and registration costs. Enter the negotiated price, trade-in allowance, what you still owe on the trade and your cash down. The accordions hold local tax, add-ons, rebates, three tax-rule switches and the loan terms for a payment estimate.
The Out-the-Door Formula Line by Line
Every buyer’s order follows the same order of lines. Start with the vehicle price and add-ons, add the tax and fees, then subtract rebates and the equity in your trade-in. Equity is the trade-in allowance minus what you still owe on it, so a loan payoff larger than the allowance adds to the total.
$$\text{OTD} = \text{Price} + \text{Add-ons} + \text{Tax} + \text{Fees} – \text{Rebates} – (\text{Trade-in} – \text{Payoff})$$
The default deal is a $40,000 car in Texas with a $15,000 trade-in, $10,000 still owed on it and a $2,000 rebate. Tax comes to $1,437.50, the doc fee and title and registration add $234, and the total lands at $34,672 out the door. After $2,000 cash down, $32,672 is left to finance, which is about $647 a month over 60 months at 7%.
What Gets Taxed Changes the Total
The tax rate is only half the story, because states disagree on what the rate is charged on. The Texas Comptroller charges motor vehicle tax on the sales price less any trade-in allowance. Its total consideration rules also remove rebates passed to the buyer and a separately stated doc fee from the taxed amount.
California works the other way. The CDTFA keeps the agreed trade-in allowance in the taxed amount, so a trade-in lowers what you owe on the car but not the tax. The calculator has switches for the trade-in credit, the rebate and the doc fee, so you can match your state’s rule.
| Same $40,000 deal, 6.25% tax | Taxed amount | Sales tax | Out the door |
|---|---|---|---|
| Trade-in and rebate both lower the tax | $23,000 | $1,438 | $34,672 |
| Trade-in lowers the tax, rebate does not | $25,000 | $1,563 | $34,797 |
| Rebate lowers the tax, trade-in does not | $38,000 | $2,375 | $35,609 |
| Neither lowers the tax | $40,000 | $2,500 | $35,734 |
The gap between the first and last rows is over $1,000 on the same car and the same rate. That is why an out-the-door quote from another state, or a figure worked out at a flat rate, can be wrong before any fee is added.
Trade It In or Sell It Yourself?
In a state that credits the trade-in, trading saves the tax on its value. In the default deal that is $937.50, so a private buyer would have to pay more than $15,938 before selling it yourself comes out ahead of the dealer’s $15,000. The trade-in card works this break-even out for your numbers.
Owners on the Leasehackr forum point out that this credit does not exist in California. There, a private sale only has to beat the dealer’s cash offer. If you owe more than the trade is worth, the calculator adds the negative equity to the deal and flags it, since paying it down first keeps it out of the new loan.
Doc Fees and Dealer Add-Ons
The doc fee is set by the dealer, not the state, and it varies widely. In Texas, the OCCC rule on documentary fees lets the regulator order restitution when a dealer charges more than $225 without a complete cost analysis. The Out the Door Price Calculator flags a Texas doc fee above that line.
Add-ons such as etching, nitrogen or protection packages are optional, and the calculator taxes them along with the car. When you enter them, the calculator shows how much declining them would take off the total, tax included.
Working Back From a Budget
Switch the calculator to Max Price From a Budget and enter the most you want to pay out the door. It works backward through the tax, fees, rebate and trade-in to the highest vehicle price that fits. With the default Texas settings, a $34,672 budget comes back to a $40,000 price.
Negotiate toward that price or lower, and the final total stays inside your budget. If you are not sure what the budget should be, the 20/4/10 Rule Calculator sizes a car to your income, down payment and loan term.
Out the Door Price Questions
What does an out-the-door price include?
It includes everything you pay to take the car home. YourCarHaggler lists the selling price, tax, registration, title, the doc fee and any dealer add-ons in the contract. A quote that leaves out tax and fees is not an out-the-door price.
Financing charges come after that total, not inside it. The calculator shows the payment separately, so the out-the-door figure stays comparable whether you pay cash or take a loan. Your cash down payment also comes off after that total, which is why the buyer’s order lists it below the out-the-door line.
Should I negotiate the out-the-door price or the monthly payment?
Negotiate the out-the-door price. A monthly payment can be lowered by stretching the loan term while the total goes up, so two offers with the same payment can cost very different amounts. The calculator’s note on the financing panel makes the same point, telling you to agree the out-the-door price first.
Once you have that number, the payment is simple arithmetic. In the default deal, the same $32,672 balance costs about $6,145 in interest over 60 months at 7%. Stretching the same balance to 72 or 84 months lowers the payment but adds more interest on top.
How do I get an out-the-door quote before visiting the dealer?
Bankrate suggests calling or emailing the dealership and asking for the out-the-door price on the exact car. It also notes that a dealer who insists you come in to talk price may be one to avoid. You can then use one dealer’s figure when negotiating with others.
When a written quote arrives, enter its lines into the calculator. If the total does not match, the line-by-line buyer’s order in the results shows where the difference is, whether that is the tax base, a fee or an add-on.
Is the dealer doc fee negotiable?
The doc fee is a dealer charge, so it can be questioned like any other part of the price. The rules differ from state to state. In Texas, a dealer charging more than $225 has to be able to back the fee with a cost analysis under the OCCC rule.
Because you compare dealers on the out-the-door total, a high doc fee on one quote can be weighed directly against a lower price on another. The Tax and Fees vs Price row shows how much of each deal goes to charges other than the car.
