Model
Samsung WH46DBH50*E*
Rank #82 means 81 of the 388 washing machine models we track cost less to run each year; the 82nd efficiency percentile means it uses less energy for its size than 82% of those models.
What does the Samsung WH46DBH50*E* cost to run per year?
Among the 388 washing machine models we track, the Samsung WH46DBH50*E* sits in the below-average-cost group, rank #82, at roughly $18 a year. Size-adjusted, this model beats 82% of washing machine models we track on efficiency, one of the stronger results in its class. Its IMEF of 3.1 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Samsung WF46BG65**A* at $18/yr runs a little cheaper and the Samsung WH46DBH55*E* at $18/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Samsung WH46DBH50*E*'s $18/yr adds up to roughly $180 in electricity alone, before purchase price or repairs.

By the numbers
The Samsung WH46DBH50*E* 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 $18/yr, here is what the Samsung WH46DBH50*E* 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 WH46DBH50*E* costs about $180. That is roughly $20 less than the class median, which would run closer to $200 over the same ten years.
How the Samsung WH46DBH50*E* compares
The washing machine class we track runs from $7 to $58 a year. At $18/yr, it runs about $2 a year cheaper than the class median of $20, and it is about $11 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.6 cu ft, the Samsung WH46DBH50*E* is a mid-size washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost. The IMEF of 3.1 on this model, above the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- Spin and wash efficiency (IMEF). IMEF is this class's core efficiency yardstick; two washers with the same drum size can carry meaningfully different IMEF figures and running costs.
- Drum volume. A larger-capacity washer can wash more per load, which can lower cost per pound of laundry, but it also draws more water and energy per cycle if you are not filling it.
- Water heating. Most washers rely on your home's hot water supply, but internal-heater sanitize or hot-wash cycles use meaningfully more electricity than a cold or warm wash.
Common questions
Is the Samsung WH46DBH50*E* cheap to run?
Yes. Its $18/yr running cost puts it at rank #82 of 388, below what most washing machine models we track cost to run.
How much does the Samsung WH46DBH50*E* cost per month?
About $1.47 a month, which is the $18 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: 95 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $18 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Samsung WH46DBH50*E* for its size?
82nd percentile once size is factored in, a fairly typical result for the class.
