If you are checking the Whirlpool H24JAK50(3B), it uses 534 kWh of electricity a year at DOE's test use. That counts an electric water heater and an electric dryer; water use is 4,720 gallons a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76, equal to its class median.
Energy and water per year
534 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: 140 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.
4,720 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 calculated the 534 kWh figure; the registry does not publish it. The figure combines the registry's IMEF of 2.76 with the washer's capacity, the drum's volume in cubic feet, of 5 cubic feet, at DOE's test use. It assumes an electric water heater and an electric dryer. ENERGY STAR files a separate machine-only figure of 140 kWh a year. That figure covers the washer and its electrically heated water alone and leaves out the dryer. The difference between the two figures is therefore the dryer's share under the test's assumptions. The page on how the yearly energy and water figures are calculated sets out each step. The registry data come from DOE CCD, retrieved 2026-10-25. This model is also sold as WFW6720R**.
Read the rest
This site also calculated the 4,720 gallons a year. It uses the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 3.2. That value is applied to the 5-cubic-foot capacity at DOE's test use. The result is a test value, not a meter reading. A household that runs more or fewer loads than the test assumes will use a different volume. The text gives no cost for this water. No free national source publishes local water and sewer rates, so any cost would be an estimate. For that reason the page gives only the volume in gallons, which the reader can check against a local utility bill.
The comparison class is the 360 models registered as front-loading, standard size. This washer's IMEF of 2.76 equals the class median of 2.76. The registry puts it at 101st highest IMEF of 360. It is rated above the federal minimum IMEF for its class, and 37 models in the class sit at that minimum. The text gives no running cost for this model. That cost depends on the reader's own utility electricity tariff, so the page works it out from the reader's ZIP. The installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote. Other models in the class are listed on all clothes washer pages.
