DMV Fee Calculator

On state vehicle sales tax, the gap between the highest and lowest state is 7.25% (California) versus 0.00% (Oregon). The median state sits at 6.00%, and the middle half of states falls between 4.22% and 6.25%.

That spread is the reason this site publishes per-state answers instead of one national average: an average of 6.00% describes 15 of 50 states well and materially misstates the rest.

the U.S. assesses vehicle registration on a FLAT fee, so every vehicle costs the same to register regardless of value, weight or age.

The larger cost at purchase is usually sales tax, not registration: U.S.'s state rate is 6.00%, which on a $30,000 vehicle is about $1,800, before local add-ons that can reach 2.00%.

Registration fee STRUCTURE differs in kind, not degree: some states charge a flat fee, some assess on vehicle value (ad valorem), some on weight, some on model year. A flat-fee state and a value-based state need different inputs and produce a different calculation, so their pages cannot be the same page with a name swapped.

Most calculator sites publish one page per state that repeats the same text with the name swapped. This one publishes a page only where the answer actually changes: 31 pages cover all 50 states, because 19 states produce an answer identical to another state's. The build measures every page against its siblings and fails if any two converge, so that property is enforced rather than intended.
