Right next to it on the list
A rank or two either side of the COSMO COS-RFQL234RSS: COSMO COS-RFFL234RSS ($113/yr, 603 kWh/yr), then Hisense RF230C4CSEI ($113/yr, 603 kWh/yr).

COSMO COS-RFQL234RSS over 13 years

Is it worth replacing?
The COSMO COS-RFQL234RSS 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 $113/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
The COSMO COS-RFQL234RSS already costs $113/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
Nothing here is estimated from a nameplate wattage; the 603 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.
