About the same electricity as the median of 39 comparable 400–499 L top-mount fridge freezer registrations (329 kWh a year). It uses less than 46% of them.
Uses 24% less than the maximum allowed for its size and type under the minimum energy performance standard (437 kWh a year MEPS level).
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 400–499 L top-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.

330 kWh × 32c/kWh. No inflation or tariff change assumed. Fridges run continuously, so the label figure is a whole-year estimate under standard test conditions.
Capacity and compartments
- Total gross volume
- 458 L
- Fresh food (fridge) volume
- 310 L
- Frozen storage volume
- 148 L
- GEMS adjusted volume
- 574 L
- fresh food compartment
- 310 L gross
- freezer compartment
- 148 L gross
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.
