Model
Whirlpool WTW8000D*+
Rank #356 means 355 of the 388 washing machine models we track cost less to run each year; the 28th efficiency percentile means it uses less energy for its size than 28% of those models.
What does the Whirlpool WTW8000D*+ cost to run per year?
The Whirlpool WTW8000D*+ costs about $36 a year to run, well up the cost table for its class at rank #356 of 388. Size-adjusted, this model trails most of its class on efficiency, ahead of just 28% of washing machine models we track. Its IMEF of 2.06 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Midea MLH52N4AWW at $33/yr runs a little cheaper and the Lg WT7155C* at $37/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 WTW8000D*+'s $36/yr adds up to roughly $360 in electricity alone, before purchase price or repairs.
By the numbers
The Whirlpool WTW8000D*+ 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 $36/yr, here is what the Whirlpool WTW8000D*+ 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 WTW8000D*+ costs about $360. That is roughly $160 more than the class median, which would run closer to $200 over the same ten years.
How the Whirlpool WTW8000D*+ compares
The washing machine class we track runs from $7 to $58 a year. At $36/yr, it runs about $16 a year above the class median of $20, and it is about $29 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5.3 cu ft, the Whirlpool WTW8000D*+ is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, and larger washing machine 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. Its IMEF of 2.06, below the class median of 2.76, reflects integrated modified energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 Whirlpool WTW8000D*+ cheap to run?
Its $36/yr running cost, rank #356 of 388, is above what most washing machine models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Whirlpool WTW8000D*+ cost per month?
About $3.03 a month, which is the $36 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: 196 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $36 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Whirlpool WTW8000D*+ for its size?
28th 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.
