Your details
Start with a realistic week
768 WFH hours
Average WFH hours per week.
Use the weeks you actually worked from home this financial year.
Actual-cost record inputs
Approximate quarterly energy bill for heating, cooling, and lighting.
Combined monthly phone, data, and internet bills.
Work-related amount supported by receipts, such as paper or ink.
Only include cleaning records for a dedicated home office.
Work-use portion you have calculated for furniture, computers, or devices.
Energy apportionment
Used only for the energy part of the actual-cost estimate.
Used with office area to apportion energy costs.
This calculator is intentionally conservative. The fixed-rate method already includes energy, phone, internet, stationery, and computer consumables, so use this to organise records for review rather than to lodge a claim on its own.
Your estimate
Actual-cost estimate is higher by $214.
Use this as a planning signal only. Your records and ATO guidance decide what is supportable.

How fixed rate works
We multiply your WFH hours by the ATO 70c/hour rate for the 2025-26 planning comparison.
How actual cost is estimated
We estimate energy, phone, internet, consumables, cleaning, and asset records as a conservative signal, not a lodging-ready claim.

Important note
The fixed-rate method uses the ATO 70c/hour rate for the 2025-26 planning comparison. The actual-cost figure is a simple estimate from records you provide, including energy, phone, internet, consumables, cleaning, and equipment inputs. It is an estimate only.
