Right next to it on the list
A rank or two either side of the Fhiaba KS300TST6IU: Fhiaba KS300TST3IU ($102/yr, 540 kWh/yr), then Fhiaba S300TST3IU ($102/yr, 540 kWh/yr).
Comparing Fhiaba's own models
Ranked 10 of Fhiaba's 18 certified refrigerators, this sits between the S240FW3U ($33/yr, the brand's cheapest) and the S360HST6IU ($109/yr, its priciest).
What this adds up to over time
Over the 13-year service life NAHB reports for this category, running the Fhiaba KS300TST6IU costs roughly $1,320 in electricity, separate from the purchase price.
Weighing a replacement
The Fhiaba KS300TST6IU 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 $102/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
The Fhiaba KS300TST6IU already costs $102/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 540 kWh/yr is ENERGY STAR's own certified figure for this model. At rank 3,671 of 4,704 for running cost, see the refrigerator category page for the rest of the field, or the guide to how much your state matters.
