Model
Whirlpool WTW6150P**
Rank #378 means 377 of the 388 washing machine models we track cost less to run each year; the 12th efficiency percentile means it uses less energy for its size than 12% of those models.
What does the Whirlpool WTW6150P** cost to run per year?
Rank #378 of 388 puts the Whirlpool WTW6150P** among the priciest washing machine models we track to keep running, at roughly $48 a year. Capacity-normalized, it ranks ahead of just 12% of washing machine models we track, a clearly below-average result. The IMEF figure of 2.06 on this model captures integrated modified energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Whirlpool WTW500CM** (V22aAf50(3B)) at $48/yr runs a little cheaper and the Whirlpool WTW6157P** at $48/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 WTW6150P**'s $48/yr adds up to roughly $480 in electricity alone, before purchase price or repairs.
Also sold as: Crosley ZWW5310R**.
By the numbers
The Whirlpool WTW6150P** 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 $48/yr, here is what the Whirlpool WTW6150P** 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 WTW6150P** costs about $480. That is roughly $280 more than the class median, which would run closer to $200 over the same ten years.
How the Whirlpool WTW6150P** compares
The washing machine class we track runs from $7 to $58 a year. At $48/yr, it runs about $28 a year above the class median of $20, and it is about $41 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5.3 cu ft, the Whirlpool WTW6150P** is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. 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 WTW6150P** cheap to run?
Its $48/yr running cost, rank #378 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 WTW6150P** cost per month?
About $4.02 a month, which is the $48 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: 260 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $48 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Whirlpool WTW6150P** for its size?
12th 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.
