What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the Bosch B20CS30SNS that long and it costs about $1,449 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The Bosch B20CS30SNS 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 $111/year every year.
