How the calculation works
Trip cost = trip miles ÷ US MPG × dollars per US gallon. A 300-mile trip at 30 MPG and $3.50 per gallon uses 10 gallons and costs $35. Include the return journey in the distance if needed.
Use a realistic starting point
Enter your measured consumption when available. EPA ratings are a consistent comparison baseline, but weather, speed, terrain and driving style change actual energy use. Prices shown here are illustrative inputs, not current national averages.
What this estimate leaves out
Parking, tolls, insurance, depreciation, maintenance, taxes and charging-network session fees are excluded. This is an energy estimate, not a total ownership-cost quotation.
