How to calculate fuel range
This calculator finds vehicle fuel range by multiplying usable fuel capacity by fuel economy.
How the calculation works
Range = Fuel capacity × Fuel economy (MPG).
Example
14 gallons at 32 MPG: 14×32 = 448 miles.
Frequently asked questions

Pro Tips for Fuel Range
- Use usable fuel capacity (accounting for the portion many vehicles reserve below 'empty') rather than total tank capacity for a more realistic range.
- Real-world range varies with driving conditions and can differ from this theoretical calculation.
Common Fuel Range Mistakes to Avoid
- Using total tank capacity instead of usable capacity, since most vehicles don't allow the fuel gauge to reach true zero before the engine stalls.
