Model
Whirlpool WTW8127L**
Rank #379 means 378 of the 388 washing machine models we track cost less to run each year; the 5th efficiency percentile means it uses less energy for its size than 5% of those models.
What does the Whirlpool WTW8127L** cost to run per year?
Few washing machine models we track cost as much to run as the Whirlpool WTW8127L**; at about $48 a year it holds rank #379 of 388. Its size-adjusted efficiency percentile of 5 means the low running cost, where it exists, is driven almost entirely by capacity rather than efficiency. 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 Whirlpool WTW8120H** at $48/yr runs a little cheaper and the Whirlpool WTW7120H** at $49/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 WTW8127L**'s $48/yr adds up to roughly $480 in electricity alone, before purchase price or repairs.
Also sold as: Maytag MVW7230H**.
By the numbers
The Whirlpool WTW8127L** 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 WTW8127L** 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 WTW8127L** 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 WTW8127L** 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 5.2 cu ft, the Whirlpool WTW8127L** is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, among washing machine models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. The IMEF of 2.06 on this model, below 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 Whirlpool WTW8127L** cheap to run?
Its $48/yr running cost, rank #379 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 WTW8127L** 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 WTW8127L** for its size?
5th 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.
