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 KFNF 9955 iDE that long and it costs about $1,359 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The Miele KFNF 9955 iDE 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 $105/year every year.
