Figures from our state pages, updated October 27, 2026
On a $30,000 car in Texas, the out-the-door total runs $32,136 with the example figures below: $1,875 in sales tax, $111 in title and registration, and an assumed $150 doc fee used as an example only. The calculator above leaves the doc fee blank for Texas, since Texas has no stated figure, so it shows $31,986 with no doc fee entered. Enter the same $150 there and the calculator matches this example. That is $2,136 over the sticker before a single monthly payment is made. The same $30,000 car in South Carolina runs $30,705 on the same doc fee, because South Carolina charges a flat $500 fee instead of a percentage tax. Same price, $1,431 apart, and that is before any dealer discount or haggling.

Calculation transparency
Jurisdiction. United States. Sales tax, title, registration, and doc fee rules are set by your state, so the total depends on where you buy and register the car.
Rules and time period. The total is the day-one amount: vehicle price plus sales tax plus title and registration plus doc fee. The payment uses a fixed-rate loan with equal monthly payments. Figures come from our state pages.
Scope and limitations. Educational estimate only. Title and registration vary by weight, age, and county; local tax can add to the total where the calculator starts from the state rate only; where no checked figure exists the field stays blank rather than guessing, so enter the rate from your quote. A buyer's order is the document that binds.

How to use
- Enter the vehicle price. The national average is $50,562 for a new vehicle (Kelley Blue Book, September 2026).
- Enter your trade-in, if any. Most states tax the price minus the trade-in, so a trade-in lowers both the tax and the amount you finance.
- Pick your state. The tax rate, title and registration, and doc fee fill in from our state pages where a figure is stated; where none is stated the field stays blank for your quote.
- Enter your down payment, loan APR, and term. Experian's Q2 2026 averages are 6.35% for a new car and 11.19% for a used car.
- Read the total, then the payment. The breakdown shows every line, so you can see which line is doing the work, and compare it against your dealer quote.
Formula
Out-the-door price equals vehicle price plus sales tax plus title and registration plus doc fee. Taxable price equals vehicle price minus trade-in, floored at zero. Sales tax equals taxable price times the tax rate, except in three states with their own rules: South Carolina charges a flat $500, Phoenix charges 9.1% on the first $14,338 then 8.3% on the rest, and Tennessee charges 7% plus 2.75% on the first $1,600 plus 2.75% on the $1,600.01 to $3,200 slice. Amount financed equals out-the-door price minus trade-in minus down payment, floored at zero. Monthly payment equals amount financed times the monthly rate divided by one minus one plus the monthly rate to the power of negative months, with the monthly rate equal to APR divided by 12. The national average combined sales tax rate is 7.53% (Tax Foundation, midyear 2026). No national average doc fee exists, so the page does not publish one: caps vary by state, and the fee on your quote is the number that counts.
Worked example, line by line
Example 1 below uses a $30,000 car in Texas with no trade-in and a $150 doc fee used as an example only. Here is the same example with each line shown, so you can check the total yourself.
| Line | How it is worked out | Amount |
|---|---|---|
| Vehicle price | Sticker price, no trade-in | $30,000 |
| Sales tax | $30,000 times 6.25% | $1,875 |
| Title and registration | $33 title plus $78 first year registration | $111 |
| Doc fee | Example only, from the dealer quote | $150 |
| Out-the-door total | $30,000 plus $1,875 plus $111 plus $150 | $32,136 |
Check: $30,000 plus $1,875 plus $111 plus $150 equals $32,136. That is $2,136 above the sticker price, or 7.1% above it. Financed in full at 8% over 60 months, the payment is $652 a month, $39,096 in total payments, and $6,960 in interest ($39,096 minus $32,136).
The other two examples check out the same way. Florida: $25,000 plus $1,500 plus $330 plus $799 equals $27,629. With $3,000 down, $24,629 is financed, which is $499 a month at 8% over 60 months, $29,963 in total payments, and $5,334 in interest. South Carolina: $30,000 plus $500 plus $55 plus $150 equals $30,705. Financed in full, that is $623 a month, $37,355 in total payments, and $6,650 in interest. Florida title and registration is shown as $330: $77.25 plus $225 plus $28 adds to $330.25, rounded to $330 in the line above.
What counts as out-the-door
Four lines, nothing hidden. The vehicle price is what the dealer advertises. Sales tax is the state and local tax on the sale. Title and registration is what the state charges to put the car in your name and plate it. The doc fee is the dealer charge for handling the paperwork. Add those four and you have the out-the-door price: the amount you owe on day one, before a down payment or a trade-in is applied.
Two things are not in the total, on purpose. Destination charges are usually already inside the advertised price on a new car, so adding them again would double count. Add-ons like paint protection, gap coverage, and dealer extras are choices, not part of the base total, and they belong on their own line of your quote if you agree to them. If a dealer total is higher than this calculator, ask which line is different. That one question usually finds the gap.
Example 1: a $30,000 car in Texas
Texas charges 6.25% on the price minus your trade-in. With no trade-in, tax on $30,000 is $1,875. Title is $33 and first year registration runs about $78 in the big metros, $111 together. Say the dealer quotes a $150 doc fee. The total is $30,000 plus $1,875 plus $111 plus $150, which is $32,136. Financed in full at 8% over 60 months, that is $652 a month and $39,096 in total payments.
Example 2: a $25,000 car in Florida, with money down
Florida charges a flat 6% state rate. Tax on $25,000 is $1,500. Title is $77.25 plus the $225 one-time initial registration fee and a $28 plate, $330 together, for a buyer with no plate to transfer. Say the dealer quotes a $799 doc fee. The total is $25,000 plus $1,500 plus $330 plus $799, which is $27,629. Put $3,000 down and $24,629 is financed, which is $499 a month at 8% over 60 months and $29,963 in total payments.
Example 3: the same $30,000 car in South Carolina
South Carolina does not charge a percentage sales tax on a car. It charges a one-time $500 Infrastructure Maintenance Fee. Title is $15 and a two year registration is $40, $55 together. With the same $150 doc fee as the Texas example, the total is $30,000 plus $500 plus $55 plus $150, which is $30,705. Financed in full at 8% over 60 months, that is $623 a month and $37,355 in total payments. The tax rule alone moves the total by $1,431 against Texas, which is why the state you pick matters as much as the price.
Why the state you pick changes the math
Most states tax a percentage of the price, but the percentage is only half the story. Some states tax the price minus the trade-in, some cap the tax, and some split it into slices. Tennessee taxes 7% statewide, but local tax only applies to the first $1,600 and a single-article tax only applies to the $1,600.01 to $3,200 slice, so a $42,000 car in Nashville owes $3,028 in tax, not the $4,095 the 9.75% headline rate would suggest. Phoenix splits its rate too: 9.1% on the first $14,338, then 8.3% on the rest, which is $3,601 on a $42,000 car. The calculator applies the Tennessee and Phoenix rules and the South Carolina flat fee automatically when you pick those states, and the note under the calculator names the rule in plain words.
Local tax is the other trap. Illinois uses the 6.25% state rate only in this calculator, and local tax will push the real total higher in most places. The same goes for Kansas, Missouri, Colorado, Utah, Washington, and Louisiana, where the calculator starts from the big city combined rate on our city page and your county may differ. Where our state page did not include a checked tax figure at all, which is California, New York, and Washington DC, the calculator leaves the rate blank rather than guessing. Enter the rate from your quote and the math follows.
Doc fees: capped in some states, open in others
The doc fee is where dealer totals diverge most, because the rules are nothing alike from state to state. California caps it at $85 or $70, New York caps it at $175, and Pennsylvania caps it at $490 electronic or $409 non-electronic for 2026. Illinois, Ohio, and Michigan cap it by law, but the dollar amount moves with inflation, so no single figure stays right for long. Texas has no hard dollar cap, and the $225 number you see online is a filing threshold, not a cap. Florida and North Carolina have no hard dollar cap in the primary law found for our dealer fees page. Our dealer fees page lays out every rule with its source, and the calculator note under the state picker repeats the rule for the state you picked.
From the total to the monthly payment
The out-the-door price is what you owe. The monthly payment is what you finance, spread out with interest. Take the out-the-door total, subtract your trade-in and your down payment, and finance the rest. At the example rate used across this site, 8% over 60 months, every $1,000 financed costs $20.28 a month. The payment page, how much will my car payment be, walks through that math in full. And once you have the payment, the calculator adds insurance, gas, upkeep, and value loss to show the full monthly cost of owning the car, not just the loan.
What this calculator does not claim
Three honest limits. First, title and registration vary by weight, age, and county in many states, so the starting figure is the standard figure from our state page and you should change it to match your quote. Second, local tax can add to the total in states where the calculator starts from the state rate only, and the state note says so where that applies. Third, this page does not publish a single national doc fee, because no such number exists. The fee on your quote is the number that counts. If the car has to be shipped to you, that freight is a separate line: see what it really costs to ship a car.
Method: taxable price equals vehicle price minus trade-in, floored at zero. Sales tax follows the rule for the state picked: flat rate on the taxable price, except South Carolina at a flat $500, Phoenix at 9.1% on the first $14,338 then 8.3% on the rest, and Tennessee at 7% plus 2.75% on the first $1,600 plus 2.75% on the $1,600.01 to $3,200 slice. Out-the-door total equals vehicle price plus sales tax plus title and registration plus doc fee. Amount financed equals out-the-door total minus trade-in minus down payment, floored at zero. Monthly payment uses a fixed-rate loan with equal monthly payments: payment equals amount financed times monthly rate divided by (1 minus (1 plus monthly rate) to the power of negative months), with monthly rate equal to APR divided by 12. Payments rounded to the nearest dollar; totals computed from the unrounded payment.
Definitions
Out-the-door price. The full amount you owe on day one: vehicle price plus sales tax plus title and registration plus doc fee.
Doc fee. Short for documentary fee: the dealer's charge for handling the sale paperwork. The dealer sets it, not the government, and caps vary by state.
Sales tax. The state and local tax on the sale, usually charged on the price minus your trade-in. The national average combined rate is 7.53% (Tax Foundation, midyear 2026).
Title and registration. What the state charges to put the car in your name and plate it. The figure varies by state, weight, age, and county.
Dealer add-ons. Optional extras like paint protection or gap coverage. They are choices, not part of the base out-the-door total, and they belong on their own line of your quote.
Questions people actually ask
What is the out-the-door price of a car?
The out-the-door price is the full amount you pay to drive the car off the lot: the vehicle price, plus sales tax, plus title and registration, plus the dealer doc fee. It is the number to compare between dealers, because two dealers can advertise the same price and still hand you different totals once tax and fees are added.
How do I calculate the out-the-door price?
Add four lines: the vehicle price, the sales tax on the taxable price, the title and registration charges, and the doc fee. If you have a trade-in, most states tax the price minus the trade-in, and the trade-in also lowers the amount you still owe. This calculator does that math for you, and every field can be changed to match your quote.
What is a doc fee, and is it capped in my state?
A doc fee, short for documentary fee, is a dealer charge for handling the sale paperwork. The dealer sets it, not the government. California caps it at $85 or $70, New York caps it at $175, and Pennsylvania caps it at $490 electronic or $409 non-electronic for 2026. Texas has no hard dollar cap, and the $225 number you see online is a filing threshold, not a cap. Florida and North Carolina have no hard dollar cap in the primary law found for our dealer fees page. Pick your state in the calculator to see the rule that applies to you.
Does sales tax apply to the full price or the price after trade-in?
In most states, including Texas, tax applies to the price minus your trade-in. A few states work differently, and some cap the tax or split it into slices, like South Carolina with its flat $500 fee and Tennessee with its single-article rule. The calculator applies the rule for the state you pick, and the note under the calculator names the rule so you can check it against your quote.
Why is the out-the-door price different from my monthly payment?
The out-the-door price is the total you owe on day one. The monthly payment spreads what you finance over the loan term, plus interest. A down payment and a trade-in lower the amount you finance, so the payment is based on the out-the-door price minus those two, not on the sticker price alone.
