Sub-Zero DEC2450FI/ against the category
That's 27.7% above the freezer category average of 401 kWh/yr, and ranks 597 of 658 certified freezers for annual running cost, 1 being cheapest. The category average comes from every freezer ENERGY STAR currently certifies (658 models), not an outside benchmark, about $21/year above that average at the national rate. See the methodology page.
What sits beside it in the ranking
Monogram ZIF241NBR ($96/yr, 513 kWh/yr) costs a little more to run than the Sub-Zero DEC2450FI/. Zline RBCFV-24 ($96/yr, 511 kWh/yr) costs a little less.
Same brand, different models
Sub-Zero makes 8 ENERGY STAR certified freezers; this one ranks 5 of 8 for running cost, between the brand's cheapest, the ID-30F at $67/yr, and its priciest, the CL3650F/S// at $120/yr.
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for freezers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Weighing a replacement
The Sub-Zero DEC2450FI/ runs above its category average. If the freezer 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 $96/year every year.
Compare current ENERGY STAR certified freezers before buying.
Protecting what you have
At $96/year just to run, a freezer is worth protecting against an unplanned repair bill on top of that.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. At rank 597 of 658 for running cost, see the freezer category page for the rest of the field, or the guide to how much your state matters.
