14% less electricity than the median of 36 comparable 500–599 L side-by-side fridge freezer registrations (452 kWh a year). It uses less than 83% of them. At 33c/kWh that is about $20 a year less than the median, $205 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 500–599 L side-by-side 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.
