What the Waykar CHWA150B costs to run
At 499 kWh/yr, the Waykar CHWA150B's ENERGY STAR certification puts it one of the more expensive models in its category to run against every other certified dehumidifier.
That $94 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.

Neighbouring models
Right next to the Waykar CHWA150B on that list: Yoau; Shinco; UHOME YDZ1-50P/6P ($89/yr, 475 kWh/yr) runs slightly less, while Waykar CHWA150E ($94/yr, 499 kWh/yr) runs slightly more.
Same brand, different models
Ranked 28 of Waykar's 39 certified dehumidifiers, this sits between the CTH30A ($22/yr, the brand's cheapest) and the CTH150PB ($97/yr, its priciest).
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
The Waykar CHWA150B runs above its category average. If the dehumidifier 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 $94/year every year.

If you're keeping it
$94/year to run is the predictable cost of the Waykar CHWA150B; a protection plan covers the unpredictable one, a repair bill.
How this was checked
Nothing here is estimated from a nameplate wattage; the 499 kWh/yr is ENERGY STAR's own certified figure for this model. The full Dehumidifier category page shows all 546 dehumidifiers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
