Estimated balance
$200
Average MPG
6.67

How it works

This estimator multiplies the miles and rate you enter, then subtracts fuel tax you enter as already paid.

It is an estimate, not a filing tool. IFTA reporting depends on jurisdiction rules, records, and the period being filed.

Assumptions

  • You enter a rate that matches the jurisdiction and period you are reviewing.
  • The result does not determine filing obligations or replace official instructions.

Worked example

With 10,000 miles, 1,500 gallons, $300 paid, and a $0.05 per-mile rate, the estimated balance is $200 and average MPG is 6.67.

FAQ

Is this an IFTA filing?

No. It is a transparent estimate only; use current official instructions and your records for filing.
