Sub-Zero ICBCL3650UID running cost

Per month: $8.77
Per year: $105
5 years: $526
10 years: $1,053

319 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: 587 L
Fresh food (fridge) volume: 439 L
Frozen storage volume: 148 L
GEMS adjusted volume: 703 L
fresh food compartment: 439 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.
