Model
Samsung WH46DBH5**G*
Rank #604 means 603 of the 615 clothes dryer models we track cost less to run each year; the 26th efficiency percentile means it uses less energy for its size than 26% of those models.
What does the Samsung WH46DBH5**G* cost to run per year?
Few clothes dryer models we track cost as much to run as the Samsung WH46DBH5**G*; at about $128 a year it holds rank #604 of 615. Efficiency-wise, once size is accounted for, it trails most of the class, ahead of only 26% of the models we track. 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 Samsung WH53DBH7**G* at $128/yr runs a little cheaper and the Samsung WH46DBH1**G* 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 Samsung WH46DBH5**G*'s $128/yr adds up to roughly $1664 in electricity alone, before purchase price or repairs.

By the numbers
The Samsung WH46DBH5**G* 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 Samsung WH46DBH5**G* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Samsung WH46DBH5**G* 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 Samsung WH46DBH5**G* 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 7.6 cu ft, the Samsung WH46DBH5**G* is a large clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 cu ft, and larger clothes dryer 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. 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 Samsung WH46DBH5**G* cheap to run?
Its $128/yr running cost, rank #604 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 Samsung WH46DBH5**G* 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 Samsung WH46DBH5**G* for its size?
26th 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.
