Model
Ge GFD40GSM****
Rank #523 means 522 of the 615 clothes dryer models we track cost less to run each year; the 3rd efficiency percentile means it uses less energy for its size than 3% of those models.
What does the Ge GFD40GSM**** cost to run per year?
Among the 615 clothes dryer models we track, the Ge GFD40GSM****'s $128/yr running cost ranks it #523, in the pricier fifth of the class. Size-adjusted, this model ranks at the very bottom of its class on efficiency, ahead of just 3% of clothes dryer models we track. Its CEF of 3.48 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Ge GFD45GSM*** at $128/yr runs a little cheaper and the Electrolux EFMG427**** 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 Ge GFD40GSM****'s $128/yr adds up to roughly $1664 in electricity alone, before purchase price or repairs.
By the numbers
The Ge GFD40GSM**** 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 Ge GFD40GSM**** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Ge GFD40GSM**** 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 Ge GFD40GSM**** 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 cu ft, the Ge GFD40GSM**** 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, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Beyond size, its CEF of 3.48, below the class median of 3.93, is the class's own efficiency yardstick, combined energy factor, and it is what separates two similarly sized models with different running costs.
- 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 Ge GFD40GSM**** cheap to run?
Its $128/yr running cost, rank #523 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 Ge GFD40GSM**** 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 Ge GFD40GSM**** for its size?
3rd 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.
