Model
Fridgemaster FMDH50PJX
Rank #456 means 455 of the 519 dehumidifier models we track cost less to run each year; the 61st efficiency percentile means it uses less energy for its size than 61% of those models.
What does the Fridgemaster FMDH50PJX cost to run per year?
At $98 a year to run, the Fridgemaster FMDH50PJX is among the more expensive dehumidifier models we track to run, ranking #456 of 519. Its 61th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Noma Iq 043-8820-8 at $98/yr runs a little cheaper and the Hisense ADH50K26 at $98/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dehumidifier typically stays in service for somewhere around 8 years; over that span, the Fridgemaster FMDH50PJX's $98/yr adds up to roughly $784 in electricity alone, before purchase price or repairs.

By the numbers
The Fridgemaster FMDH50PJX normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $98/yr, here is what the Fridgemaster FMDH50PJX adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Fridgemaster FMDH50PJX costs about $980. That is roughly $340 more than the class median, which would run closer to $640 over the same ten years.
How the Fridgemaster FMDH50PJX compares
The dehumidifier class we track runs from $19 to $521 a year. At $98/yr, it runs about $34 a year above the class median of $64, and it is about $79 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.95 pints/day, the Fridgemaster FMDH50PJX is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. Beyond size, its IEF of 2.01, above the class median of 2.01, is the class's own efficiency yardstick, integrated energy factor, and it is what separates two similarly sized models with different running costs.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Fridgemaster FMDH50PJX cheap to run?
Not especially. At $98 a year it ranks #456 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Fridgemaster FMDH50PJX cost per month?
Roughly $8.14/mo, spreading the $98/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 526 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $98 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Fridgemaster FMDH50PJX for its size?
61st percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
