Model
Whirlpool WFW5620H**
Rank #279 means 278 of the 388 washing machine models we track cost less to run each year; the 42nd efficiency percentile means it uses less energy for its size than 42% of those models.
What does the Whirlpool WFW5620H** cost to run per year?
Do the math and the Whirlpool WFW5620H**'s $26/yr puts it at rank #279 of 388, on the pricier side of the class. Adjusted for size, it is more efficient than 42% of washing machine models we track, a middling result. At a IMEF of 2.76, its integrated modified energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Whirlpool WFC682CL** at $26/yr runs a little cheaper and the Whirlpool WFW6620H** at $26/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 Whirlpool WFW5620H**'s $26/yr adds up to roughly $260 in electricity alone, before purchase price or repairs.

By the numbers
The Whirlpool WFW5620H** 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 $26/yr, here is what the Whirlpool WFW5620H** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Whirlpool WFW5620H** costs about $260. That is roughly $60 more than the class median, which would run closer to $200 over the same ten years.
How the Whirlpool WFW5620H** compares
The washing machine class we track runs from $7 to $58 a year. At $26/yr, it runs about $6 a year above the class median of $20, and it is about $19 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Whirlpool WFW5620H** 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 2.76 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). A higher Integrated Modified Energy Factor means the machine wrings more useful washing (and a drier spin) out of every kilowatt-hour and gallon it uses.
- Drum volume. Drum volume sets the ceiling on how much a single cycle can wash, and it is usually the first driver of a washer's per-cycle energy use.
- Water heating. Cycle temperature, more than drum size, is usually what separates a cheap wash cycle from an expensive one on models with an internal water heater.
Common questions
Is the Whirlpool WFW5620H** cheap to run?
Not especially. At $26 a year it ranks #279 of 388 washing machine models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Whirlpool WFW5620H** cost per month?
Roughly $2.15/mo, spreading the $26/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 139 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $26 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Whirlpool WFW5620H** for its size?
42nd 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.
