Enter the distance, efficiency, and fuel price in the same selected system. The calculator does not fetch routes or live fuel prices.
Planning estimate only, not financial, tax, or legal advice. Verify assumptions and current rules before making decisions.

How this calculator works
Formula
MPG mode: gallons = total miles ÷ MPG. Metric mode: liters = total kilometers × L/100 km ÷ 100. Total distance applies the return-journey and trip-count choices. Fuel cost = fuel used × entered price, then cost per traveler divides equally.
Worked example
A 120-mile one-way journey, including the return, repeated twice is 480 miles. At 30 MPG and $3.50 per gallon, it uses 16 gallons and costs $56, or $14 each for four travelers.
Assumptions to verify
- Distance, efficiency, and fuel price use the same selected unit system.
- The entered efficiency is treated as constant across the trip.
- Tolls, parking, maintenance, charging, traffic, detours, and depreciation are excluded.
Frequently asked questions
Does this calculator fetch a route?
No. Enter the distance yourself; no map, location, or routing service is contacted.
Can I use liters per 100 kilometers?
Yes. Select metric mode and enter distance in kilometers, efficiency in L/100 km, and price per liter.
What costs are excluded?
The result covers entered fuel cost only and excludes tolls, parking, maintenance, depreciation, and other travel expenses.
