How Much Does It Cost To Run The Dishwasher – 2024

Introduction – Cost To Run The Dishwasher

[Update: 1/14/2024 we updated the costs by using the most up to date average electricity rates and low and high ranges of electricity rates across 50 states]

The dishwasher is a great addition to any kitchen, providing a convenient and easy way to wash dishes. It saves time and energy compared to washing dishes by hand, allowing you more time for other tasks. While dishwashers use a fair amount of energy to operate, modern models are more efficient than ever. So, how much does it cost to run the dishwasher?

Washers and dryers contribute to about 10% of home energy usage

In addition to electricity costs, other factors, such as water usage and detergents, influence the overall cost of running a dishwasher. Newer, efficient dishwashers consume 23 liters (6 gallons) of water per cycle, which can add up if you run multiple daily cycles.

As for detergents, you’ll need to buy specialized dishwasher tablets or powders since regular detergents are not designed for the dishwasher and can damage the appliance. We’re going to ignore those extra costs and focus on the electricity costs.

How Much Does It Cost To Run The Dishwasher?

We examined dishwasher data compiled on the Energy Star site which was set up by the EPA and DOE. As of 2022, Energy Star listed 838 models of dishwashers and their annual electricity usage based on average usage patterns.

We found the average energy use of all these dishwashers and report the results here. Using average electricity costs for all 52 states, we computed that it costs between $0.06-$0.31 to run the dishwasher per day; it costs between $1.98-$9.68 to run the dishwasher per month; it costs between $22.77-$111.32 to run the dishwasher per year. All estimates are based one a single use per day.

Per Day (use once)0.70 kWh$0.08 – $0.30
Per Month22 kWh$2.64 – $9.46
Per Year253 kWh$30.36 – $108.79

For example, if you live in an area where one kWh costs approximately $0.20, it will cost you around 16 cents to run a single cycle in the dishwasher — the water use will be less than washing by hand. Additionally, many newer models come with various energy-saving features, such as soil sensors or delay start options, which can help you save on your utility bills even more.

We assumed that electricity costs (as of Jan 2024) range from $0.12 in North Dakota to $0.43 in Hawaii. This gives a range for the operational costs.

The cost of running the dishwasher is worth it since it saves time and energy. Using a dishwasher can also reduces water waste since it uses less water than washing dishes by hand. So if you’re looking to upgrade your kitchen and save money, investing in an energy-efficient dishwasher may be the way to go!

How To Save Money On Your Dishwasher?

All it requires is a few simple steps.

Firstly, ensure you only use the dishwasher when it’s full and run it at its lowest temperature setting; this will help conserve energy and money.

Secondly, scrape off the food before placing dishes in the dishwasher to avoid the pre-wash cycle, which can significantly increase water costs.

Thirdly, purchase a high-efficiency model with an ENERGY STAR® label that features shorter wash cycles, so you don’t use more hot water than necessary. To cut down on electricity bills further, switch off your dishwasher at night or during peak electricity hours to get cheaper nighttime rates if available in your area.

Fourthly, if you’ve had your dishwasher for some time, look into having it regularly serviced as part of regular maintenance to help ensure its efficiency isn’t decreasing over time — leading to higher bills down the line. With these tips, you can save money each month on your dishwashing expenses!

What Factors Affect The Cost Of Running A Dishwasher?

Many people tend to underestimate the cost of running a dishwasher when several factors can drive up the price. The amount of energy and water used, a buildup of detergent residue, inefficient rinse cycles, and model and price points all contribute to the overall cost.

Regarding energy use, size matters; larger models use more energy. Therefore, investing in a model that best suits your family’s size and usage needs makes sense. The residue left behind tends to increase long-term energy costs due to its ability to reduce the efficiency of the dishwasher’s heating element; ensure you’re using enough detergent but not too much, as this is key in avoiding an extra buildup inside the dishwasher over time.

Inefficient rinse cycles can also significantly raise energy costs by waiting until the end of a cycle before beginning a full cycle. Finally, don’t forget that purchase price still matters – higher-end models offer better performance when cleaning dishes for less money than lower-end versions. They are worth the investment in potential savings down the line!

Is It Cheaper To Run A Dishwasher At Night?

Possibly. The electricity price ranges we considered above is $0.09 to $0.44 because across the US the rates differ due to fragmented markets and differing regulatory schemes. Each market or region itself may have differential day and night-time pricing.

Where energy costs are variable, during peak times of the day, like in the morning or during rush hour in the evening, energy companies typically charge more than off-peak hours, like late at night. So if you live in an area with dynamic pricing incentives or time-of-use rates – meaning energy prices differ by the time they are used – it may be cheaper to run your dishwasher at night when prices are lower.

Additionally, you can compare the cost-effectiveness of running your dishwasher during peak versus off-peak times by using helpful online tools such as rate comparison calculators and energy usage tracking data charts.

By researching and understanding how electricity pricing works in your area, you’ll be better equipped to decide when it is best for you to use certain types of appliances – including your dishwasher – and conceivably save money in the process.

How To Run Your Dishwasher More Efficiently?

Running your dishwasher more efficiently can be a great way to reduce your energy and water consumption. To get the most out of your dishwasher while using fewer resources, ensure it is filled before you turn it on.

For heavily soiled items, use a pre-rinse cycle before washing to remove any stubborn bits of food. You should also check the manufacturer’s instructions and use the recommended detergent type — typically powder or tablet detergent. When available, select the eco or economy wash setting – this will provide excellent results while using less water than a standard cycle.

Utilizing your dishwasher’s delay-start feature can help you take advantage of cheaper overnight electricity rates and conserve additional energy. Finally, keep the filters in good condition and free of excess residue. Following these steps will ensure that you’re washing dishes in an efficient manner that minimizes your energy consumption!


In conclusion, choosing the right dishwasher for your needs and running it efficiently can save you money on energy bills in the long run. By understanding how electricity pricing works in your area, you can time your dishwasher running more effectively to maximize savings.

Additionally, pre-rinsing heavily soiled items, using the recommended detergent type, selecting an eco or economy wash setting when available, and keeping filters clean are all key to ensuring that your dishwasher operates at peak efficiency. With some planning and know-how, you can be sure that your household’s dishwashing habits are cost-effective and energy efficient!
