Why generic calculators get it wrong

They ask YOU for the tax rate

We look it up — state + county + district for your ZIP, with the edge cases handled: Florida's surtax stops at $5,000; Washington adds 0.3% on vehicles; Texas is flat 6.25% everywhere.

They miss the state rules

California taxes your rebate and gives no trade-in credit. Texas does the opposite. On a $40,000 deal with a $10,000 trade, that's a four-figure difference in tax alone.

They can't see real doc fees

Where doc fees are capped, we show the statute. Where they aren't, we show what real buyers report — per state, and over time per dealership.

Just bought — or just got a quote?

Every itemized report makes the next buyer harder to overcharge. Add-ons, F&I products, and doc fees are captured line by line — anonymously. Quotes you walked away from count too.
