I built a free tool that shows car registration fees for all 50 states

I keep hearing the same story. Someone moves to a new state, walks into the DMV, and the total is triple what they expected.

Every state charges differently. And DMV sites usually only list the base registration fee. They skip the title fee, the plate fee, the local add-ons, and the taxes that pile on top. So I pulled the full numbers for all 50 states (registration, title, taxes) into one free tool: https://statefeecalculator.com

A few things that surprised me while building it:

• The spread is huge. Some states charge under $50 a year to register a car. Others charge several hundred before taxes even enter the picture.
• Low fees don't mean low cost. A state with a $30 registration fee can still cost you thousands at purchase if the sales tax is high.
• Movers get the worst surprises. Some states charge use tax on your car's current value when you re-register, even if you already own the car.
• No two states structure it the same way. Weight-based, value-based, flat fee, county add-ons. It's a mess, which is why I built the thing.

It's free and there's no signup. If you spot a number that's off or a fee I missed, tell me. Feedback is the whole reason I'm posting this here.
