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.
Shopping for a new one
The KOOLATRON KKUF21-* 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.

Protecting what you have
Whether or not the KOOLATRON KKUF21-* ever needs replacing, a repair is the more common failure for a freezer, one a protection plan budgets for ahead of time.
