182 kWh × 33c/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: 328 L
Fresh food (fridge) volume: 328 L
Frozen storage volume: –
GEMS adjusted volume: 328 L
fresh food compartment: 328 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.
