Sub-Zero CL4850S/S/* against the category
That's 93.3% above the refrigerator category average of 386 kWh/yr, and ranks 4,606 of 4,704 certified refrigerators for annual running cost, 1 being cheapest. The category average comes from every refrigerator ENERGY STAR currently certifies (4,704 models), not an outside benchmark, about $68/year above that average at the national rate. See the methodology page.
What sits beside it in the ranking
Jenn-Air JS42PPDUDE** ($141/yr, 752 kWh/yr) costs a little more to run than the Sub-Zero CL4850S/S/*. Samsung RF27T5501** ($140/yr, 746 kWh/yr) costs a little less.
Same brand, different models
Among Sub-Zero's 26 certified refrigerators, this is the priciest to run, $110/year over the DEU2450R/ADA/*, the brand's cheapest.
What this adds up to over time
13 years is NAHB's typical service life for this category; at $140/year, the Sub-Zero CL4850S/S/* adds up to about $1,823 in electricity over that span.
Weighing a replacement
The Sub-Zero CL4850S/S/* runs above its category average. If the refrigerator you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $140/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
A refrigerator like the Sub-Zero CL4850S/S/* is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
Sourcing
Nothing here is estimated from a nameplate wattage; the 746 kWh/yr is ENERGY STAR's own certified figure for this model. The full Refrigerator category page shows all 4,704 refrigerators ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
