KOSTCH KOS-36RF##- Running Cost (Refrigerator)
KOSTCH KOS-36RF##-: running cost
The KOSTCH KOS-36RF##- is certified by ENERGY STAR at 658 kWh a year, one of the more expensive models in its category to run among refrigerators currently certified.
That $124 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 70.5% above it, ranking 4,321 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 $51/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 KOSTCH KOS-36RF##-: Ikea OVERSKADLIG ($124/yr, 658 kWh/yr), then L2 LRQ22D6 ($124/yr, 658 kWh/yr).
Within the KOSTCH lineup
The KOSTCH KOS-36RF##- is the only refrigerator from KOSTCH that ENERGY STAR currently certifies, so there's no same-brand model to weigh it against here, only the full refrigerator category.
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the KOSTCH KOS-36RF##- that long and it costs about $1,608 in electricity, on top of whatever it cost to buy.
Weighing a replacement
The KOSTCH KOS-36RF##- 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 $124/year every year.
Compare current ENERGY STAR certified refrigerators before buying.
If you're keeping it
The KOSTCH KOS-36RF##- already costs $124/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
Where this number comes from
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. The 658 kWh/yr figure is ENERGY STAR's own certification, not a wattage estimate; exact dataset IDs are on the data sources page.
