Checking the Whirlpool V21zAe57(3B)? At DOE's test use it needs 745 kWh a year with an electric water heater and electric dryer. Water use is 6,596 gallons a year under the same test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.06, ranking 37th highest of 870 models in its class.
Energy and water per year
745 kWh a year with an electric water heater and an electric dryer
Computed by this site from the registry's IMEF and drum capacity at DOE's test use of 295 cycles a year. IMEF counts the washer, heating its water electrically, and the electric dryer's work on what the spin leaves wet — so this is the total for that kind of home. How it is calculated
The machine and its hot water alone, dryer not included: 260 kWh a year, as ENERGY STAR files it.
Not published: A home with a gas water heater, a gas dryer or line drying
DOE's rating assumes electric water heating and an electric dryer and files no split between the machine, the water heating and the drying.
Such a home uses less electricity than the total above; how much less, no registry says for this model.
6,596 gallons of water a year
Computed from the registry's IWF and drum capacity at the same 295 cycles a year.
Not published: What the water costs
water and sewer rates are set by thousands of local utilities and no free national source publishes them.
The gallons above are the figure to multiply by your own water and sewer rate.
This model is rated above the federal minimum IMEF for its class.

This site computed the figure of 745 kWh a year, and the registry does not publish it. It combines the registry's IMEF of 2.06 with the capacity, the drum's volume in cubic feet, of 5.2. The calculation assumes DOE's test use, an electric water heater and an electric dryer. The source is DOE CCD, retrieved 2026-10-25, and ENERGY STAR files a machine-only figure of 260 kWh. That covers the washer and its electrically heated water, without the dryer. This page does not give the dryer's share on its own, because the two figures come from different sources.
The water figure of 6,596 gallons is also computed by this site. It applies the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 4.3. The same capacity of 5.2 cubic feet and DOE's test use complete the calculation. Read how the yearly energy and water figures are calculated for the steps. No cost for this water is stated, because no free national source publishes local water and sewer rates. A household that runs more or fewer cycles than DOE's test use would see a different yearly figure.

Among the 870 models registered as top-loading, standard size, this model's IMEF of 2.06 is above the class median of 1.57. Its rank is 37th highest IMEF of 870. It is rated above the federal minimum IMEF for its class, and 652 models in the class sit at that minimum. The minimum value itself is not available on this page. You can browse all clothes washer pages for other models. Running cost depends on your own utility electricity tariff, so no amount is written here. The page computes it from your ZIP, using the 745 kWh a year figure with an electric water heater and electric dryer.
