8% more electricity than the median of 29 comparable Under 200 L fridge freezer (manual-defrost freezer) registrations (204 kWh a year). It uses less than 14% of them. At 32c/kWh that is about $5 a year more than the median, $54 over 10 years.

Uses 34% less than the maximum allowed for its size and type under the minimum energy performance standard (336 kWh a year MEPS level).

How efficient is it for its size?

kWh per year. Bar: the middle 80% of 29 comparable Under 200 L fridge freezer (manual-defrost freezer) registrations. Dot: this model (above the median). Hover or tab to a mark for its value.

Cohort: every currently registered Under 200 L fridge freezer (manual-defrost 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.

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.
