Out-the-Door Price — Missouri

The sticker isn’t the price. Enter your numbers and get an itemized breakdown — tax, title, and fees included — so you can give it a proper side-eye before you ever sit down.

How to use it: enter the agreed price, pick your state, add your trade and financing — the out-the-door total builds line by line in The Math.

Missouri's 4.225% state rate looks like one of the lowest in the country, but local taxes do serious work here: city and county rates commonly add 3–5 points, and combined rates in parts of the St. Louis and Kansas City metros push past 9%. The rate is set by where you live, not where you buy — so know your own combined rate before trusting any quote.

Two pieces of good news. The trade-in credit applies in full, and Missouri also allows a credit for the proceeds when you've sold a vehicle yourself within a window around the purchase — so even a private sale of your old car can reduce the tax on the new one, a flexibility most states don't offer. Doc fees are capped (inflation-indexed, around $620 for 2026), which is high for a cap but at least a ceiling.

One Missouri-specific habit matters more than anything above: the state famously does not let dealers collect sales tax at purchase on every deal — buyers often pay the tax themselves at the license office when titling. That means driving home doesn't mean the tax is settled, and budgeting the out-the-door number without the tax check in hand has burned plenty of Missourians with a surprise four-figure bill at the DMV window. Our total includes it; make sure your bank account does too.

Every figure above was last verified against official Missouri sources in July 2026. Tax rules do change — the final word is always your paperwork and the DMV.
