Climate zone

Electricity pricec/kWh

Energy rating (cooling): 1.5; Heating: 0.5
Annual electricity use: 889 kWh; 344 cooling + 545 heating
Estimated running cost: $284 / year; $24 / month · $2,845 over 10 years
Capacity: 2.8 kW cooling; 2.5 kW heating

4% more electricity than the median of 23 comparable 2.5 kW reverse cycle window / wall registrations (852 kWh a year) in the mixed zone. Uses less than 0% of them.

Across all 3,681 air conditioner registrations sold in Australia, it uses less than 80% (this compares very different sizes, so the cohort figure above is the useful one).

Annual kWh is the government label figure for a residential user in the mixed zone (Richmond NSW climate: Sydney, Melbourne, Adelaide, Perth). Mixed climate zone shown by default (Sydney, Melbourne, Adelaide, Perth); switch to cold or hot. Cost = kWh × 32c/kWh in AUD; change the price above to your tariff.
