Right next to it on the list
A rank or two either side of the Waykar CTH150D: Vellgoo TAURUS PRO-RCS50(Y)-N4-3-25 ($83/yr, 444 kWh/yr), then Waykar CTH150PD ($89/yr, 471 kWh/yr).
Same brand, different models

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.
Shopping for a new one
At $89/year, this is on the expensive side for a dehumidifier; the cheapest certified model in this category runs about $20/year, worth knowing before buying either the Waykar CTH150D or its replacement.

If you're keeping it
A dehumidifier like the Waykar CTH150D is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 471 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 360 of 546, the Waykar CTH150D sits in the middle of the dehumidifier category, see the guide to why your state changes this number for the other half of the math.
