Trip fuel cost
Estimate fuel volume and expense for a trip using your distance, consumption and fuel price.
How the math works
Reference formulas use CAD, kilometres and litres. Inputs are converted to this basis before calculation and results are converted back for display.
Keep in mind
- Driver labour, maintenance, ownership costs, overhead and additional trip expenses are excluded.
- A single consumption figure does not separately model idling, terrain, load, weather or auxiliary equipment. Zero consumption or price is allowed as an explicit scenario, not a typical assumption.
- Keep the fuel price on the same tax basis as any other costs you compare it with.
Precision is retained during calculation. Displayed numbers are rounded. Export for the full calculated values.
Common questions
How much fuel would a 500 km trip use?
In a hypothetical CAD/km/L example, 500 km at 30 L/100 km uses 150 L. At C$1.60/L, estimated fuel spend is C$240, or C$0.48/km. Replace the distance, consumption and price with your own assumptions; the calculator does not measure actual consumption.
Can I enter mpg in the fuel-consumption box?
No. Enter fuel volume per 100 distance units, following the label beside the box. The header’s gallon option means US gallons. If your figure is mpg, use the fuel economy converter first and choose US or Imperial mpg explicitly; they use different gallon volumes.
Is the fuel-spend result the full cost of the trip?
No. It uses only distance, fuel consumption and fuel price. Driver labour, maintenance, equipment costs, overhead and additional trip expenses are outside this result. For a loaded-distance rate, use the break-even calculator with an operating-cost figure that covers the costs you intend to include.
