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
Efficient as certified freezers go, $74/year is a reasonable baseline if you're comparing what else is on the market.
Compare current ENERGY STAR certified freezers before buying.
If you're keeping it
