Formula Used
Baseline fuel tax = Average Virginia miles ÷ Reference MPG × Fuel tax rate.
Vehicle fuel tax = Average Virginia miles ÷ Vehicle combined MPG × Fuel tax rate.
Annual HUF = max(0, Baseline fuel tax − Vehicle fuel tax) × HUF percentage.
Term fee = Annual HUF × Registration years.
Mileage Choice estimate = min(Annual HUF, Annual HUF ÷ Average miles × Expected miles).
For electric vehicles, the calculator uses the maximum annual fee field.

What Is the Virginia Highway Use Fee?
Virginia adds a highway use fee to many efficient vehicles. The fee helps replace fuel tax that is not paid at the pump. High mileage ratings can lower gasoline use. They can also lower fuel tax collections. This calculator gives an estimate before renewal. It is useful for gasoline cars, hybrid models, plug in hybrids, and electric vehicles.
Why the Fee Matters
The fee can change a registration budget. A driver may compare the annual charge, a two year renewal, or a three year renewal. The estimate also shows the fuel tax comparison behind the result. This helps explain why a very efficient car may owe more than a regular gasoline car.
How the Estimate Works
The tool compares two fuel tax amounts. First, it estimates tax for a reference vehicle. The default reference rating is 23.7 miles per gallon. Next, it estimates tax for your vehicle rating. The positive difference is multiplied by the highway use percentage. The default percentage is 85 percent. Electric vehicles can use the maximum annual fee field.
Mileage Choice Planning
Some drivers may prefer a mileage based option. The calculator estimates that option by spreading the annual fee across average Virginia miles. Then it multiplies the rate by your expected miles. The value is capped at the annual highway use fee. This gives a quick view of possible savings when you drive less.
Using the Results
Use the annual result for a one year registration. Use the term result for longer renewals. Review the fuel tax gap to understand the charge. Check the mileage estimate if your annual driving is low. Download the CSV for a spreadsheet. Download the PDF for records.
Important Notes
This page is an estimator. Official DMV systems decide the final bill. Rates can change each July. Vehicle data may also differ from owner estimates. Use the manufacturer combined MPG when possible. For final registration questions, review your DMV renewal notice. Keep a dated copy of each estimate. It can help compare renewals after fuel tax changes. Update the default tax rate when a new chart appears. Small rate changes can move the total by several dollars for careful yearly planning purposes.
FAQs
What is the Virginia highway use fee?
It is a registration-related fee for many efficient vehicles. It helps offset lower fuel tax payments from vehicles that use less gasoline or no gasoline.
Which MPG should I enter?
Use the manufacturer combined MPG rating. It is usually listed on the fuel economy label, owner documents, or vehicle research pages.
Why is 23.7 MPG used?
The calculator uses 23.7 MPG as the reference rating. The highway use fee estimate compares fuel tax from that reference vehicle with your vehicle.
Can electric vehicles use this calculator?
Yes. Select electric as the vehicle type. The calculator then uses the maximum annual fee field instead of a gasoline MPG calculation.
What is the Mileage Choice estimate?
It estimates a per-mile payment option. It divides the annual fee by average miles, multiplies by your expected miles, and caps the result.
Does this calculator give the official DMV bill?
No. It is only an estimate. Official DMV records, rates, vehicle data, and renewal rules decide the final amount due.
Why can the fee change each year?
The fuel tax rate and official fee schedules can change. Update the default rate when new DMV values are published.
Can I download my result?
Yes. Press the CSV button for spreadsheet data. Press the PDF button for a simple record of the estimate.
