Frequently Asked Questions
As fuel prices rise, what is the federal gas tax?
The U.S. federal excise on gasoline is 18.4 cents per gallon (cpg) before state and local add-ons. Diesel differs. Values can change only by statute.
Would a holiday erase all pain at the pump?
No. State taxes and crude price moves often dominate. Suspending only the federal slice saves roughly pennies per gallon times your annual gallons.
How do I estimate gallons?
Annual miles ÷ MPG gives gallons per year. Multiply by months of holiday over 12 for partial years.
Do EVs matter here?
This model is for gasoline vehicles. EVs avoid motor fuel excise but may face registration or road-use fees in some states.
Is legislation guaranteed?
No. This is a scenario calculator for proposed bills discussed in headlines.
