About this calculator
Trip fuel cost is distance divided by efficiency, then multiplied by the price of fuel. You can work in miles and gallons or kilometers and liters.
How to calculate
Choose a unit system, enter distance, vehicle efficiency, and the price you pay at the pump.
US: Cost = (Miles / MPG) × Price per gallon
Metric: Cost = (Km / 100) × L/100 km × Price per liter
When to use it
- A road-trip budget
- Comparing two routes by distance only
Examples
300 miles, 30 mpg, $3.50/gal
Fuel used is 10 gallons. Cost is $35.00.
300 km at 7 L/100 km
| Fuel price | Fuel used | Cost |
|---|---|---|
| $1.50 / L | 21 L | $31.50 |
| $1.80 / L | 21 L | $37.80 |
| $2.00 / L | 21 L | $42.00 |
FAQ
Should I use advertised MPG?
Real-world efficiency is often lower. A recent tank average is more useful than the window-sticker number.
Does this include tolls or parking?
No. It is fuel only.
