Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for freezers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Weighing a replacement
The KOOLMORE KM-RUF-21S runs above its category average. If the freezer 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 $93/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
A freezer like the KOOLMORE KM-RUF-21S is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
