6% less electricity than the median of 10 comparable 500โ€“599 L top-mount fridge freezer registrations (369 kWh a year). It uses less than 70% of them. At 33c/kWh that is about $8 a year less than the median, $79 over 10 years.

Uses 24% less than the maximum allowed for its size and type under the minimum energy performance standard (452 kWh a year MEPS level).

How efficient is it for its size?

kWh per year. Bar: the middle 80% of 10 comparable 500โ€“599 L top-mount fridge freezer registrations. Dot: this model (below the median). Hover or tab to a mark for its value.

Cohort: every currently registered 500โ€“599 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.
