Fuel Economy Calculator
Calculate your actual MPG or km/L from odometer readings and gas receipts.
Track fuel economy over multiple fill-ups.
Your Fuel Economy
Fuel economy measures how far your vehicle travels on a given amount of fuel.
Imperial formula (MPG):
MPG = Miles Driven / Gallons Used
Metric formula (km/L):
km/L = Kilometers Driven / Liters Used
How to measure accurately:
- Fill your tank completely
- Reset your trip odometer (or note the odometer reading)
- Drive normally until you need fuel again
- Fill up completely again and note the gallons or liters added
- Record the miles or km driven since the last fill-up
- Divide distance by fuel to get your actual economy
Typical fuel economy ranges:
| Vehicle Type | MPG | km/L |
|---|---|---|
| Small car | 30-40 | 13-17 |
| Sedan | 25-35 | 11-15 |
| SUV | 18-28 | 8-12 |
| Truck | 14-22 | 6-9 |
| Hybrid | 40-55 | 17-23 |
