Samsung RF31CG7400 Running Cost (Refrigerator)
What the Samsung RF31CG7400 costs to run
At 774 kWh/yr, the Samsung RF31CG7400's ENERGY STAR certification puts it one of the more expensive models in its category to run against every other certified refrigerator.
That $146 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.
Efficient, or not, for a refrigerator
The category average is 386 kWh/yr; this model runs 100.5% above it, ranking 4,662 of 4,704 refrigerators tracked here for running cost. That average is drawn from all 4,704 refrigerators ENERGY STAR currently certifies, not an outside number, a $73/year gap from this model at the national rate. Full sourcing is in the sourcing notes.
Right next to it on the list
A rank or two either side of the Samsung RF31CG7400: Samsung RF80H30CE ($144/yr, 764 kWh/yr), then Café CQE28DMN ($146/yr, 776 kWh/yr).
Same brand, different models
Ranked 97 of Samsung's 101 certified refrigerators, this sits between the RT18DG6300 ($63/yr, the brand's cheapest) and the RF32CG5B30 ($148/yr, its priciest).
Cost over its typical lifespan
13 years is NAHB's typical service life for this category; at $146/year, the Samsung RF31CG7400 adds up to about $1,892 in electricity over that span.
Weighing a replacement
The Samsung RF31CG7400 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 $146/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
$146/year to run is the predictable cost of the Samsung RF31CG7400; a protection plan covers the unpredictable one, a repair bill.
Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. 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.
