- WF45B63**A*
If you're checking the Samsung WF45B63**A*, it uses 428 kWh a year at DOE's test use with an electric water heater and electric dryer. It uses 3,850 gallons of water a year under the same test. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 3.1, above its class median of 2.76.
Energy and water per year
428 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: 93 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.
3,850 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.

The 428 kWh total is computed by this site, not printed by the registry. It combines the registry's IMEF with its capacity, the drum's volume in cubic feet, here 4.5, at DOE's test use. Those inputs come from DOE's CCD, retrieved 2026-10-25. Because IMEF counts drying, the total assumes an electric dryer dries every load. ENERGY STAR files a separate machine-only figure of 93 kWh a year for this model. That figure covers the washer and its electrically heated water, with the dryer left out. The gap between 93 kWh and 428 kWh is therefore the dryer's share under the test. The steps are set out on the page about how the yearly energy and water figures are calculated.
Read the rest
IWF, the gallons of water used per cycle for each cubic foot of drum, is 2.9 for this model. This site multiplies it by the 4.5 cubic foot drum at DOE's test use to reach 3,850 gallons a year. A lower IWF means less water for each cubic foot of drum. The page does not state what that water costs. No free national source publishes local water and sewer rates, so any cost figure here would be an estimate. Anyone checking a bill can apply their own local water and sewer rate to the 3,850 gallons figure. The same test assumptions behind the energy total apply to this water figure as well.
This model is compared with the 360 models registered as front-loading, standard size. Its IMEF of 3.1 ranks 5th highest of 360, which places it above the class median given earlier. It is rated above the federal minimum IMEF for its class, while 37 models in the class sit at that minimum. The minimum value itself is not available in this data. The running cost is not written in this text because it depends on the reader's own utility electricity tariff. Instead, the page computes it from the reader's ZIP. The installed-cost range appears in its own block, with its source and date, as a modeled range rather than a quote. Other models in the same class are listed under all clothes washer pages.
