How to Read a Dishwasher Energy Guide Label
Short answer: The EnergyGuide label on a dishwasher shows the estimated yearly energy cost, yearly electricity use, and water consumption per cycle. These figures assume 215 cycles per year and a national average energy price. ENERGY STAR certified models meet strict limits: standard-size models use no more than 240 kWh/year and 3.2 gallons per cycle, while compact models use no more than 155 kWh/year and 2.0 gallons per cycle. Use the label to compare similar models and estimate your own operating costs when shopping.
What the EnergyGuide Label Shows
When you shop for a dishwasher, you’ll see a yellow label attached to the unit. That is the EnergyGuide label, a federal requirement designed to help you compare the energy and water consumption of similar models. The label shows two key pieces of information: the estimated yearly operating cost and the estimated yearly electricity use in kilowatt-hours. It also includes a water consumption figure, usually expressed in gallons per cycle.
The EnergyGuide label is not the same as ENERGY STAR certification. ENERGY STAR is a voluntary program that recognizes models that exceed federal efficiency standards, as described in dishwasher ENERGY STAR requirements. The yellow label is mandatory, while the ENERGY STAR badge is earned by meeting specific criteria.
Reading the Yearly Energy Cost and Electricity Use
The EnergyGuide label prominently displays an estimated yearly operating cost. This number is calculated using a standardized formula that assumes 215 cycles per year and a national average residential energy price. The same formula also produces the estimated yearly electricity use in kWh, which tells you how much electricity the dishwasher will consume over a year of typical use.
According to the Department of Energy test procedure, the federal EnergyGuide label shows the estimated yearly electricity use and estimated yearly energy cost. These figures use the annual energy consumption, average cycles per week, and the average cost of energy. The label does not show the annual energy consumption (AEC) number itself, as noted in the ENERGY STAR criteria.
When comparing models, look for lower yearly electricity use to reduce your environmental impact, but also consider water consumption. Heating water accounts for a significant portion of the total energy a dishwasher uses, so a model with lower water use often saves energy as well.
Understanding Water Consumption per Cycle
The EnergyGuide label also includes the estimated water consumption, typically expressed in gallons per cycle. This is often called the water factor. Lower gallons per cycle means less water is used for each load, which can save water and reduce the energy needed to heat that water.
ENERGY STAR sets maximum water consumption limits: standard-size dishwashers (8 place settings or more) must use no more than 3.2 gallons per cycle, while compact models (fewer than 8 place settings) must use no more than 2.0 gallons per cycle. These thresholds help you quickly identify efficient models, and they are part of the current ENERGY STAR criteria.
If you run your dishwasher frequently, the gallons-per-cycle figure matters a lot. A small difference of even 0.5 gallons per cycle adds up over hundreds of loads, so choose the lowest water use within your desired capacity class.
How ENERGY STAR Criteria Compare
ENERGY STAR certification is based on specific energy and water consumption limits set by the U.S. Department of Energy and the Environmental Protection Agency. Models that meet these limits may display the ENERGY STAR label, which signals that they are among the more efficient options on the market. The criteria became effective on July 19, 2023.
The table below summarizes the current maximum limits. Note that these are maximums; many certified models perform better. The EnergyGuide label on each model will show its specific estimated usage, so you can compare within the certified group.
| Capacity | Maximum Energy Use (kWh/year) | Maximum Water Use (gallons/cycle) |
|---|---|---|
| Standard (≥ 8 place settings + 6 serving pieces) | 240 | 3.2 |
| Compact (< 8 place settings + 6 serving pieces) | 155 | 2.0 |
How to Use the Label When Choosing a Dishwasher
Start by checking the yellow label on each model you consider. Write down the estimated yearly electricity use in kWh and the water consumption in gallons per cycle. Also note the estimated yearly cost, but remember that the label uses a national average energy price. For a more personal estimate, multiply the kWh per year by your local electricity rate and the water use by your local water and sewer rates.
Consider your household’s dishwasher usage. If you run fewer than 215 cycles per year, your actual annual cost will be lower than the label’s estimate; if you run more, it will be higher. Adjust the label’s figures by scaling them to your typical number of loads.
Compact models may use less energy and water per cycle, but because they hold fewer dishes, you may need to run more loads, which can increase total energy and water use over time. ENERGY STAR notes that compact models may use more energy than standard models over time due to smaller capacity.
Finally, look for the ENERGY STAR logo if you want a model that meets strict efficiency criteria. You can also use the ENERGY STAR Most Efficient designation to find the top performers. If you have a small kitchen, explore countertop dishwashers or 18-inch models; for a standard capacity, see 24-inch dishwashers.

Questions
What is the difference between the EnergyGuide label and the ENERGY STAR label?
The EnergyGuide label is a federal requirement that shows estimated energy and water usage. ENERGY STAR is a voluntary certification for models that meet stricter efficiency criteria set by the EPA and DOE.
Why does the EnergyGuide label assume 215 cycles per year?
That is the average annual cycle count used in the Department of Energy’s test procedure for dishwashers, as stated in the ENERGY STAR criteria document.
Does the EnergyGuide label show the annual energy consumption (AEC)?
No. According to the ENERGY STAR criteria, the label shows estimated yearly electricity use and cost, but the AEC number is not printed on the label.
Are compact dishwashers more efficient than standard models?
They may use less energy and water per cycle, but because they hold fewer dishes, you may need to run extra loads. ENERGY STAR notes that compact models may use more energy than standard models over time.
Can I use the EnergyGuide label to estimate my own utility bills?
Yes, but the label uses a national average energy price. To get a closer estimate, multiply the kWh per year by your local electricity rate and the water use by your water and sewer rates.
Is the ENERGY STAR Most Efficient designation the same as ENERGY STAR certified?
No. Most Efficient is a recognition for the best performers within the certified group, based on the ENERGY STAR program, as noted on the ENERGY STAR products page.
