10% more electricity than the median of 48 comparable 300–399 L bottom-mount fridge freezer registrations (293 kWh a year). It uses less than 27% of them. At 32c/kWh that is about $9 a year more than the median, $90 over 10 years.

Cost = label kWh × 32c/kWh in AUD; change the price above to your tariff.
How efficient is it for its size?
Cohort: every currently registered 300–399 L bottom-mount fridge freezer sold in Australia, counted once per registration. Star ratings already account for size through the GEMS adjusted-volume formula; this comparison is in raw kWh against models a buyer would actually consider instead.

Capacity and compartments
- Total gross volume
- 323 L
- Fresh food (fridge) volume
- 233 L
- Frozen storage volume
- 90 L
- GEMS adjusted volume
- 394 L

Gross volumes exclude shelving. Fresh food = fresh food, chill and cellar compartments; frozen = freezer, two-star and ice-making (zero-star) compartments. Adjusted volume weights frozen space more heavily and is what the government uses to set the star rating for the size.
