Calculation breakdown
Method, assumptions and worked example
Credit for each entry = eligible litres × verified cents-per-litre rate ÷ 100. Total credit is the sum of those entries. Group fuel only when the same rate and eligibility treatment apply.
Worked arithmetic example
Using a hypothetical rate of 20 cents per litre, 1,000 eligible litres produces 200 in credit. Another 500 litres at a hypothetical 10 cents produces 50, for 250 total. These rates demonstrate arithmetic only; they are not a current ATO rate recommendation.
Before entering a rate
Use the ATO eligibility tool and rates guidance for the acquisition date, fuel type and activity. Do not assume every business litre qualifies or apply today’s rate to an earlier purchase. Enter only the eligible quantity after separating private or ineligible use.
This calculator does not select rates or assess registration, fuel eligibility, road-user-charge treatment, adjustments or simplified methods. Keep invoices and your eligible-use calculation with the result. Follow ATO instructions for BAS reporting and rounding.
Frequently asked questions
Why is there no automatic current rate?
Rates depend on fuel acquisition date and activity. Enter a verified applicable rate for each group rather than applying one potentially wrong rate to every purchase.
Can I mix purchases from different rate periods?
Yes. Add a separate entry for each applicable rate and eligible quantity.
