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 Insignia NS-UZ21WH0 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.

The Insignia NS-UZ21WH0 already costs $93/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
Sourcing
