10% more electricity than the median of 50 comparable 300–399 L top-mount fridge freezer registrations (312 kWh a year). It uses less than 12% of them. At 33c/kWh that is about $10 a year more than the median, $104 over 10 years.

Cost = label kWh × 33c/kWh in NZD; change the price above to your tariff.
How efficient is it for its size?
Cohort: every currently registered 300–399 L top-mount fridge freezer sold in New Zealand, 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
- 320 L
- Fresh food (fridge) volume
- 245 L
- Frozen storage volume
- 75 L
- GEMS adjusted volume
- 379 L
- freezer compartment
- 75 L gross
- fresh food compartment
- 245 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.
