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
Efficient as certified freezers go, $81/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
The Commercial Cool CCUC1640GB already costs $81/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
