Formula and methodology
Formula: Distance = ending odometer - starting odometer; fuel economy = distance / fuel added; fuel cost = fuel added x price.
The calculator uses the interval between two readings rather than relying on a vehicle display or a route-distance estimate.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Starting odometer — minimum 0; maximum 1000000000
- Ending odometer — minimum 0; maximum 1000000000
- Fuel added — minimum 1.0E-6; maximum 10000000
- Distance unit — 2 choices
- Fuel unit — 2 choices
- Price per fuel unit — currency; minimum 0; maximum 100000
Worked example
| Input | Value |
|---|---|
| Starting odometer | 12000 |
| Ending odometer | 12360 |
| Fuel added | 15 |
| Distance unit | mi |
| Fuel unit | gal |
| Price per fuel unit | 3 |
360 miles / 15 gallons = 24.0 mi/gal and $45 fuel cost.
Assumptions and limits
- The tank is filled consistently enough that the fuel added represents fuel consumed over the odometer interval.
- Fuel price and units are entered consistently; one interval can be distorted by partial fills, traffic, weather, or terrain.
