See FleetZap Maintenance · Try the demoThe formula
Gallons = Miles ÷ mpg · Fuel cost = Gallons × Price per gallon
With the example: 350 miles at 6.5 mpg is 53.8 gallons, about $204.62 at $3.80. Five trips a week on four trucks is about $4,090 a week. Use your real mpg from fuel logs, and the miles from the planned route, not the straight-line distance. The truck routing guide covers cutting the miles themselves.
Using the numberWhat to do with it
- Shorter routes save more than cheaper fuel: every mile cut saves fuel, wear and driver time.
- Idling adds fuel without miles; the fleet fuel savings calculator puts a number on it.
- Price loads and service calls with the trip’s fuel cost in them, especially on long or rural runs.

Good to know
How do you calculate fuel cost for a trip?Divide the trip's miles by the vehicle's mpg to get gallons, then multiply by the price per gallon. 350 miles at 6.5 mpg and $3.80 is about $205.
Should I use one-way or round-trip miles?Round-trip, if the vehicle comes back empty or on the same route. Empty miles burn fuel too.
How can a fleet cut trip fuel costs?Shorter, planned routes, less idling, correct tire pressure and steady speeds. Measure real mpg from fuel logs before and after.
How do I calculate fuel consumption?Fuel used = miles ÷ miles per gallon. A 350 mile trip at 6.5 mpg uses about 53.8 gallons.
