Model
Tcl T50DC9R
Rank #482 means 481 of the 519 dehumidifier models we track cost less to run each year; the 47th efficiency percentile means it uses less energy for its size than 47% of those models.
What does the Tcl T50DC9R cost to run per year?
Among the 519 dehumidifier models we track, the Tcl T50DC9R's $98/yr running cost ranks it #482, in the pricier fifth of the class. Capacity-normalized, it ranks ahead of 47% of dehumidifier models we track, right in the class's middle band. At a IEF of 2.01, its integrated energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Moiswell Defender MP70 at $98/yr runs a little cheaper and the Tcl T50DC9SPB 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 Tcl T50DC9R's $98/yr adds up to roughly $784 in electricity alone, before purchase price or repairs.

By the numbers
The Tcl T50DC9R 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 Tcl T50DC9R adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Tcl T50DC9R 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 Tcl T50DC9R 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 50 pints/day, the Tcl T50DC9R is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. The IEF of 2.01 on this model, above the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- Integrated Energy Factor (IEF). IEF measures liters of water removed per kilowatt-hour; a higher IEF means less energy per pint of moisture removed for a given capacity.
- Water removal capacity (pints/day). A dehumidifier rated to remove more pints per day is built for a larger space or a more humid room, and generally draws more power to do it.
- Humidistat accuracy. A unit with a more precise humidistat cycles the compressor off once the target humidity is reached, rather than running continuously.
Common questions
Is the Tcl T50DC9R cheap to run?
Its $98/yr running cost, rank #482 of 519, is above what most dehumidifier models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Tcl T50DC9R cost per month?
About $8.2 a month, which is the $98 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 530 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $98 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Tcl T50DC9R for its size?
47th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
