Right next to it on the list
A rank or two either side of the Miele KFMC 3858 FD: Samsung RF24BB6600** ($118/yr, 630 kWh/yr), then Samsung RF23DB9900** ($119/yr, 631 kWh/yr).
Within the Miele lineup
Ranked 57 of Miele's 58 certified refrigerators, this sits between the KWTUS 7172 F ($19/yr, the brand's cheapest) and the KFFD 6721 ($123/yr, its priciest).
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 Miele KFMC 3858 FD that long and it costs about $1,542 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The Miele KFMC 3858 FD 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 $119/year every year.

If you're keeping it
The Miele KFMC 3858 FD already costs $119/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
