Model
Maytag MGD6630H**
Rank #571 means 570 of the 615 clothes dryer models we track cost less to run each year; the 4th efficiency percentile means it uses less energy for its size than 4% of those models.
What does the Maytag MGD6630H** cost to run per year?
The Maytag MGD6630H** costs about $128 a year to run, well up the cost table for its class at rank #571 of 615. Capacity-normalized, it ranks ahead of just 4% of clothes dryer models we track, near the bottom of every model we track in the class. The CEF figure of 3.48 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Maytag MGD5630H** at $128/yr runs a little cheaper and the Maytag MGD8630H** at $128/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A clothes dryer typically stays in service for somewhere around 13 years; over that span, the Maytag MGD6630H**'s $128/yr adds up to roughly $1664 in electricity alone, before purchase price or repairs.
Also sold as: Ge Profile PTD90GB*T***.
By the numbers
The Maytag MGD6630H** 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 $128/yr, here is what the Maytag MGD6630H** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Maytag MGD6630H** costs about $1280. That is roughly $150 more than the class median, which would run closer to $1130 over the same ten years.
How the Maytag MGD6630H** compares
The clothes dryer class we track runs from $23 to $128 a year. At $128/yr, it runs about $15 a year above the class median of $113, and it is about $105 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 7.3 cu ft, the Maytag MGD6630H** is a small clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The CEF of 3.48 on this model, below the class median of 3.93, measures combined energy factor; it is the number to compare directly against another model's CEF if capacity is similar.
- Heat source and Combined Energy Factor (CEF). Heat-pump dryers recycle heat instead of generating it fresh with a resistance coil, and typically use meaningfully less electricity per load than a conventional resistance dryer, at the cost of a longer cycle; CEF is the federal figure that captures this.
- Drum capacity. A larger drum can dry a bigger load per cycle, but it also usually needs more energy per cycle to heat the extra air volume.
Common questions
Is the Maytag MGD6630H** cheap to run?
Its $128/yr running cost, rank #571 of 615, is above what most clothes dryer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Maytag MGD6630H** cost per month?
About $10.63 a month, which is the $128 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: 687 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $128 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Maytag MGD6630H** for its size?
4th 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.
