Model
Bosch WTG86403UC
Rank #79 means 78 of the 615 clothes dryer models we track cost less to run each year; the 72nd efficiency percentile means it uses less energy for its size than 72% of those models.
What does the Bosch WTG86403UC cost to run per year?
Rank #79 of 615 puts the Bosch WTG86403UC among the cheapest clothes dryer models we track to keep running, at roughly $59 a year. Size-adjusted, this model beats 72% of clothes dryer models we track on efficiency, better than most of its class. The CEF figure of 2.68 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Electrolux ELFE4222*** at $59/yr runs a little cheaper and the Fisher&Paykel DE4024P2 at $59/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 Bosch WTG86403UC's $59/yr adds up to roughly $767 in electricity alone, before purchase price or repairs.
Also sold as: Aeg DC240.
By the numbers
The Bosch WTG86403UC 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 $59/yr, here is what the Bosch WTG86403UC adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bosch WTG86403UC costs about $590. That is roughly $540 less than the class median, which would run closer to $1130 over the same ten years.
How the Bosch WTG86403UC compares
The clothes dryer class we track runs from $23 to $128 a year. At $59/yr, it runs about $54 a year cheaper than the class median of $113, and it is about $36 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 4 cu ft, the Bosch WTG86403UC 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, and smaller clothes dryer models generally cost less to run for the same job, all else being equal. The CEF of 2.68 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 Bosch WTG86403UC cheap to run?
Yes. Its $59/yr running cost puts it at rank #79 of 615, below what most clothes dryer models we track cost to run.
How much does the Bosch WTG86403UC cost per month?
About $4.9 a month, which is the $59 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: 317 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $59 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bosch WTG86403UC for its size?
72nd 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.
