How Much Does a Car Really Cost in Missouri?

Missouri figures checked November 2, 2026

The tax you pay on day one: Missouri car sales tax

Missouri charges sales tax on a car at the state rate of 4.225%, plus local tax, on the price minus your trade-in. That trade-in credit simply means the value of the car you trade in comes off the taxable price before the tax is figured. The worked example on this page uses the state rate alone: on a $42,000 car with no trade-in, that is $1,774.50 of state tax on day one. With a $15,000 trade-in, you would be taxed on $27,000 instead, which comes to $1,140.75.

Your city and county add their own tax on top of the state rate, by your address, so most buyers pay more day-one tax than the example line shows. The statewide average combined rate is 8.44% (Tax Foundation). In St. Louis, for example, the combined rate is 9.679%. Your exact rate depends on your address, so check it in the Missouri Department of Revenue rate-finder before you buy. The example on this page is the state-rate figure, not a quote for a single address.

The yearly bill most buyers miss: Missouri personal property tax on a car

Here is what makes Missouri different from most states on this site. Missouri charges a personal property tax, a yearly tax on the car itself, based on what it is worth, every year you own the car. It is not a one-time fee. It is a bill that comes back annually, and it is the cost that surprises Missouri buyers most.

The math works in two steps. First, the state sets the car's assessed value, the taxable slice of the car's value, at 33⅓% of its market value, figured from pricing guides. Then that assessed value is multiplied by the local levy, the local tax rate your city, county, school district, library, and other districts set. The levy is the part that varies by address, and it prints on your own tax bill. And one practical point: you need proof the tax is paid (or a waiver saying the car was not assessed) before you can renew your plates.

No single statewide bill exists, because no single levy exists, so this page illustrates the bill with one county's published schedule, clearly labeled as an illustration and not a statewide figure: Jackson County's schedule total of 8.3015 per $100 of assessed value for a Kansas City city and school district address, the latest complete published schedule retrieved, dated 2020, stated plainly because levies move yearly. The Kansas City page walks through this same illustration for its own example. On the worked example below, with the truck's market value falling evenly from $42,000 to $21,000, the start-of-year values are $42,000, $37,800, $33,600, $29,400, and $25,200, giving yearly bills of $1,162, $1,046, $930, $814, and $697, or $4,649 over five years. Your county's levy gives a different bill.

Title and registration: how much does it cost to register a car in Missouri?

The title itself costs $8.50, plus a $9 processing fee, $17.50 all in. Annual registration for a passenger car runs $18.25 to $51.25 a year by taxable horsepower, taxable horsepower is a state rating of engine size used to set the fee, not the horsepower number on the window sticker. A typical passenger car falls in the 24-to-47 taxable-horsepower band at $24.25 to $33.25 a year, plus a $9 processing fee for a one-year registration ($18 for two years). Trucks, including all pickups, pay by weight instead of horsepower, and by whether the truck runs locally (within 50 miles of home) or over a wider area: local 6,000 lbs costs $15.75, local 12,000 lbs $18.25, beyond-local 6,000 lbs $25.75, beyond-local 12,000 lbs $38.25, local 18,000 lbs $20.75, beyond-local 18,000 lbs $63.25, local 24,000 lbs $27.75, and beyond-local 24,000 lbs $100.75, each plus a $9 processing fee for one year. Electric vehicles fall in the under-12 horsepower class at $18.25, and also pay an annual alternative-fuel decal on top of registration. The 2026 decal price is not stated on this page, because published sources conflict on it, so check it with the Department of Revenue before you buy.

Put the yearly government stack together for the example on this page and it is a modest registration fee plus a much larger personal property tax bill. That balance, small registration, yearly car tax, is the Missouri pattern, and it is the opposite of Texas, where there is no yearly car tax at all.

Emissions and safety checks

An emissions test, a check that the car's exhaust is clean enough, is not statewide in Missouri. It applies only in St. Louis City and in St. Louis, St. Charles, and Jefferson counties, under the Gateway Vehicle Inspection Program, for gasoline vehicles from model year 1996 on and diesel vehicles from model year 1997 on, up to 8,500 lbs, at a $24 fee cap. The rest of Missouri has no emissions test. A safety inspection, a check that brakes, lights, and other safety parts are in working order, applies statewide every two years, unless the car is within its first 10 model years and under 150,000 miles, at a $12 fee cap ($10 for motorcycles). Test fees depend on when your car is due, so they sit outside the six lines of the worked example below rather than being folded into a number that would not apply every year.

How much is car insurance in Missouri?

Full-coverage insurance in Missouri runs about $2,160 to $2,431 a year. That range, not a single average, is the honest number: Insurify's average through September 2026 runs about $180 a month, and a benchmark built from insurer filings with state regulators (driver age 40, clean record, 100/300/100 limits, $500 deductibles, priced across 287 Missouri ZIP codes) runs $2,431 a year. Different sources count different drivers and different coverage, so the range is the finding. Missouri's minimum coverage is 25/50/25, $25,000 per person and $50,000 per accident for injuries to others, plus $25,000 for damage to someone else's property, plus uninsured-motorist coverage, which covers you if the other driver has no insurance.

Insurance is the recurring line buyers most often price after they have already fallen for a car. Get the quote before you sign, not after.

Gas: a statewide average, not a pump price

Missouri's statewide average for regular gas was $3.83 a gallon (AAA, November 2, 2026). That is a snapshot from one day, and gas prices move weekly, it is the price used for the fuel line below, not a promise about what gas will cost over five years. If a newer statewide average is published later, the fuel line should be refreshed.

What Missouri drives

Statewide rankings mostly do not exist in reliable form, so this page labels every popularity claim by its level. For used cars, the statewide data is solid: the Ford F-150 is Missouri's most popular used car at 3.5% of 1- to 5-year-old used sales (iSeeCars, 2024 study). The St. Louis metro tells a newer, different story at its own level, the Chevrolet Malibu led the metro in 2025 at 4.3%, so the F-150 lead is the statewide finding, not a permanent crown. One list this page deliberately does not use as a popularity ranking: fastest-selling lists, which measure how quickly cars turn over on lots, not how many people buy them.

For new cars, there is no reliable current statewide ranking, so this page claims none. A weak single source once named the F-150 the most-registered new vehicle in Missouri in early 2025, and this page does not repeat a weak claim as a finding.

A full Missouri example: a $42,000 pickup

Every figure below comes from the site's own calculator math with Missouri inputs, the same $42,000 example vehicle as the Texas and St. Louis pages, so the three states compare line for line. The stated inputs are: new full-size pickup, $42,000 price, 10% down ($4,200), 8% APR (the yearly interest rate on the loan), 60 months, Missouri state sales tax 4.225% ($1,774.50, no trade-in; local tax would add more by address), $900 in title and dealer fees (the same combined allowance as the Texas and St. Louis examples, so the comparison stays clean; Missouri's own title charge is $8.50 plus $9 processing, and dealer paperwork varies by dealer), truck registered at local 6,000 lbs ($15.75 plus $9 processing a year), 12,000 miles per year, 19 mpg, $3.83 per gallon (the Missouri statewide average, AAA November 2, 2026), $2,295 per year insurance (the example value inside the $2,160 to $2,431 range, the midpoint, rounded to the nearest $5), $1,000 per year maintenance, $21,000 resale value after five years. The financed amount is $40,474.50, which works out to $821 a month on the loan.

• Depreciation: $21,000 ($42,000 minus $21,000 resale)
• Insurance: $11,475 ($2,295 x 5 years)
• Fuel: $12,095 (12,000 / 19 x $3.83 x 5 years)
• Maintenance: $5,000 ($1,000 x 5 years)
• Tax, fees and interest: $11,441 ($1,774.50 sales tax, $900 fees, $8,766 loan interest)
• Registration & annual vehicle taxes: $4,728 ($15.75 x 5 years registration, a truck registered at local 6,000 lbs, plus the $4,649 Jackson County property tax illustration: $1,162, $1,046, $930, $814, $697)

That totals $65,739 over five years, or about $1,096 a month. The Missouri pattern in one sentence: the day-one state tax is lower than St. Louis's combined rate, but local tax and then the yearly personal property tax bill still come, the lines Texas does not have at all. The $9-a-year registration processing fee and the emissions and safety test fees, when due, sit on top of this total; they are small next to the lines above, but they are real, so they are named here rather than hidden.

Formula

The five-year total is the sum of six buckets: depreciation, insurance, fuel, maintenance, tax, fees and interest, and registration and annual vehicle taxes. Depreciation is the $42,000 price minus the $21,000 resale value after five years, which is $21,000. Insurance is $2,295 a year times 5 years, which is $11,475. Fuel is 12,000 miles a year divided by 19 miles per gallon, times $3.83 a gallon, times 5 years, which is $12,095. Maintenance is $1,000 a year times 5 years, which is $5,000. Tax, fees and interest is $1,774.50 of sales tax, $900 in title and dealer fees, and $8,766 of loan interest, which is $11,441. Registration and annual vehicle taxes are $4,728 over five years: $15.75 a year registration times 5 years, a truck registered at local 6,000 lbs, plus the $4,649 Jackson County property tax illustration, $1,162, $1,046, $930, $814, and $697.

Added together, $21,000 plus $11,475 plus $12,095 plus $5,000 plus $11,441 plus $4,728 equals $65,739, or about $1,096 a month. The financed amount is the $42,000 price plus $1,774.50 sales tax plus $900 in fees, minus the $4,200 down payment, which is $40,474.50. At 8% APR over 60 months, the payment on $40,474.50 is $821 a month, and the loan costs $8,766 in interest over five years.

Definitions

Sales tax. The tax you pay when you buy a car. Missouri charges sales tax on a car at the state rate of 4.225%, plus local tax, on the price minus your trade-in. On a $42,000 car with no trade-in, the state tax alone is $1,774.50. The statewide average combined rate is 8.44%, and in St. Louis it is 9.679%.

Trade-in credit. Your old car, counted toward the price of the new one. The trade-in credit means the value of the car you trade in comes off the taxable price before the tax is figured: with a $15,000 trade-in, you would be taxed on $27,000 instead, which comes to $1,140.75.

Personal property tax. A yearly tax on the car itself, based on what it is worth, every year you own the car. It is not a one-time fee, it is a bill that comes back annually, and it is the cost that surprises Missouri buyers most.

Assessed value. The taxable slice of the car's value. The state sets the car's assessed value at 33 1/3% of its market value, figured from pricing guides.

Local levy. The local tax rate your city, county, school district, library, and other districts set. The assessed value is multiplied by the local levy, and the levy is the part that varies by address and prints on your own tax bill.

Title fee. The one-time fee to put the car in your name. The title itself costs $8.50, plus a $9 processing fee, $17.50 all in.

Registration. The yearly fee for the license plate. Annual registration for a passenger car runs $18.25 to $51.25 a year by taxable horsepower. Trucks, including all pickups, pay by weight instead: local 6,000 lbs costs $15.75 a year.

Processing fee. A $9 fee for a one-year registration, $18 for two years, charged on top of the registration fee.

Emissions test. A check that the car's exhaust is clean enough. It applies only in St. Louis City and in St. Louis, St. Charles, and Jefferson counties, under the Gateway Vehicle Inspection Program, at a $24 fee cap. The rest of Missouri has no emissions test.

Safety inspection. A check that brakes, lights, and other safety parts are in working order. It applies statewide every two years, unless the car is within its first 10 model years and under 150,000 miles, at a $12 fee cap.

Full-coverage insurance. Insurance that covers damage to your own car, not just damage you cause to others. In Missouri it runs about $2,160 to $2,431 a year, and the worked example uses $2,295 a year, the midpoint of that range, rounded to the nearest $5.

APR. Annual percentage rate, the yearly interest rate on the loan. This example uses 8%. For context, Experian reported average rates of 6.35% on new cars and 11.19% on used cars in the second quarter of 2026.

Depreciation. The value the car loses over time. On this page, the $42,000 price minus the $21,000 resale value after five years, which is $21,000.

Common questions

How much is the Missouri car sales tax?

The state rate is 4.225%, charged on the price minus your trade-in, and your city and county add local tax on top, so your combined rate depends on your address. The statewide average combined rate is 8.44% (Tax Foundation). The worked example on this page uses the state rate alone: on a $42,000 car with no trade-in, that is $1,774.50. Check your exact rate in the Missouri Department of Revenue rate-finder for your address.

How does Missouri's yearly property tax on a car work?

Missouri taxes cars every year at 33⅓% of the car's market value, multiplied by your local levy (the local tax rate). The levy varies by county, so no single statewide bill exists. As an illustration only, this page uses Jackson County's published schedule total of 8.3015 per $100 of assessed value for a Kansas City city and school district address, the latest complete published schedule retrieved, dated 2020, because levies move yearly. Your bill will differ with your levy, and the levy prints on your own bill.

How much does it cost to register a car in Missouri?

Registration runs $18.25 to $51.25 a year by taxable horsepower (a state engine-size rating used to set the fee), typically $24.25 to $33.25 for a passenger car, plus a $9 processing fee for one year. The title costs $8.50 plus $9 processing. You also need proof your personal property tax is paid before you can renew your plates.

How much is car insurance in Missouri?

Figures from the Missouri Department of Revenue, the Tax Foundation, AAA (Missouri statewide average, November 2, 2026), Insurify, insurancequotes.com, and iSeeCars (2024 study). Insurance is published as a range because sources count different drivers and coverage; gas is a dated snapshot, not a five-year rate; the personal property tax example is a labeled Jackson County illustration because no single statewide levy exists; and no 2026 EV decal price is published here because published sources conflict on it. County fees, levies, and insurance quotes vary by driver and address, the structure above is the part that does not change.
