Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, 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 dehumidifiers go, $48/year is a reasonable baseline if you're comparing what else is on the market.

If you're keeping it
At $48/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
