Why MPG Matters for IFTA
Average MPG is one of the most important numbers in the IFTA reporting process.
It helps determine how fuel is allocated across states and supports accurate quarterly reporting.
Example Calculation
If a truck travels:
- 15,000 miles
- 2,500 gallons of fuel
The average MPG would be:
6.0 MPG
Common MPG Tracking Mistakes
Drivers often:
- Estimate fuel usage
- Forget fuel purchases
- Lose receipts
- Enter mileage incorrectly
Small errors can create larger reporting problems later.
Beyond the Calculator
A calculator is useful for quick estimates.
However, owner-operators still need a system to:
- Track mileage by state
- Record fuel purchases
- Review totals
- Export reports
