Right next to the Brothers 301090 on that list: Amazon Basics B0GR2TS1X4 ($99/yr, 525 kWh/yr) runs slightly less, while Coolworks TDUDP-50AEN8-BB0 ($99/yr, 525 kWh/yr) runs slightly more.
Within the Brothers lineup
The Brothers 301090 is the only dehumidifier from Brothers that ENERGY STAR currently certifies, so there's no same-brand model to weigh it against here, only the full dehumidifier category.
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 Brothers 301090 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 $99/year every year.

If you're keeping it
A dehumidifier like the Brothers 301090 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.
How this was checked
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. At rank 464 of 546 for running cost, see the dehumidifier category page for the rest of the field, or the guide to how much your state matters.
