LG LBNC15231* over 13 years
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the LG LBNC15231* that long and it costs about $1,039 in electricity, on top of whatever it cost to buy.
Weighing a replacement
The LG LBNC15231* 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 $80/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
Whether or not the LG LBNC15231* ever needs replacing, a repair is the more common failure for a refrigerator, one a protection plan budgets for ahead of time.
