Understanding Dishwasher Electricity Usage: Watts, kWh, and Running Costs
Understanding your dishwasher’s energy consumption helps you become familiar with terms like watts and kilowatt-hours (kWh). Don’t worry, it’s simpler than it sounds! Here’s a quick rundown:
Watts measures the rate of energy consumption at a given moment. Most dishwashers use between 1,000 and 1,800 watts, but it varies based on the machine’s type, size, settings, and age.
Kilowatt-hours (kWh) are what you’re billed for on your electric bill. One kWh represents the use of 1,000 watts over an hour. So, if your dishwasher runs at 1,200 watts for an hour, it’s using 1.2 kWh.
Why does this matter? Because understanding how many watts and kWh your dishwasher uses can help you predict its impact on your energy bill. Factors like the wash cycle length, whether you use heated drying, and even the load size affect energy use, too. Knowing these details can give you more control over your dishwasher’s costs.
How to Calculate Your Dishwasher’s Electricity Costs
Now that you know the basics of watts and kWh, it’s time to get specific! Using our energy calculator, you can estimate how much each load is really costing you. Here’s how:
Find Your Dishwasher’s Wattage: This should be listed in the user manual or on a label somewhere on the machine. If it’s around 1,200-1,500 watts, you’re in the average range.
Estimate Your Cycle Length: Most regular cycles last around 1.5 to 2 hours, but it’s best to check your dishwasher’s cycle times to be exact.
Check Your Electricity Rate: Look at your utility bill for the cost per kWh. Rates vary depending on where you live and can change based on the time of day.
Just plug these numbers into the calculator below, and voilà! You’ll get a realistic look at how much each load is costing. It’s a simple way to turn abstract numbers into practical insights that might even inspire a few adjustments to save on your monthly bill.

Average Cost of Running a Dishwasher
So, what’s the average cost of running a dishwasher? While it varies by machine and usage habits, here’s a ballpark figure to give you an idea:
Per Cycle: Depending on your electricity rate and dishwasher’s energy use, the cost typically ranges from $0.10 to $0.40 per load.
Monthly Costs: If you’re running it daily, that adds up to around $3–$12 a month, though costs can go higher if you run multiple cycles or use additional heat-drying features.
Running your dishwasher during off-peak hours (often late at night) can help lower costs, as some utilities offer lower rates during these times. Plus, regional electricity costs play a role, so where you live can affect your bill more than you might expect.
How Much Does It Cost to Run a Dishwasher? Real-World Examples
Now that you know the basics, let’s look at real-world examples to see how much running your dishwasher might cost. These examples can give you a rough idea based on different scenarios:
Example 1: Daily Usage of a Standard Dishwasher
Suppose you’re running a 1,200-watt dishwasher daily on a standard cycle (about 1.5 hours per load) with an average electricity rate of $0.13 per kWh. In that case, it might cost around $5–$6 per month.
Example 2: Every-Other-Day Usage of an Energy-Efficient Dishwasher
For an Energy Star-certified dishwasher used every other day, with a shorter eco cycle and a rate of $0.13 per kWh, the monthly cost could be as low as $2–$3.
These calculations illustrate that even small adjustments, like using eco mode or running fewer loads, can make a noticeable difference in your monthly costs. And, of course, your local electricity rates will also impact these costs, so it’s worth checking your area’s specific rates.
When Is the Best Time to Run Your Dishwasher?
Timing can make a surprising difference in how much you pay to run your dishwasher. Many utility companies offer off-peak rates during specific hours (usually late night or early morning) when energy demand is lower. By adjusting your dishwasher routine, you could take advantage of these reduced rates and save money in the long run.
Here are some tips to help you time your loads for maximum savings:
Check Your Utility’s Off-Peak Hours: Often, this is as easy as checking your utility’s website or giving them a call.
Set Your Dishwasher’s Delay Start Feature: Many dishwashers come with this feature, allowing you to set it to start automatically during off-peak times.
Shifting your dishwasher use by just a few hours can lead to noticeable savings over time, especially if you’re a regular user.
Comparing Dishwasher and Hand-Washing Energy Efficiency
It’s an age-old debate: is it cheaper to hand-wash dishes or just load the dishwasher? The answer may surprise you! Dishwashers, especially newer models, are often more efficient than hand-washing in terms of both water and energy use.
Water Use: On average, dishwashers use around 3-5 gallons of water per cycle, whereas hand-washing can easily use up to 20 gallons if you’re not careful. For water savings alone, the dishwasher wins.
Energy Use: Dishwashers are designed to heat water efficiently. Since they heat only what they need for each load, they can be more energy-efficient than constantly running hot water from the tap.
So, the next time you’re debating between hand-washing and running a load, consider this: if your dishwasher is reasonably full and energy-efficient, it’s probably the greener and more budget-friendly choice.

Tips for Reducing Dishwasher Energy Costs
I know it feels good when your electricity bill is not high. Let our dishwasher contribute to our happiness. Here are some easy tweaks to make it run more efficiently:
Run Full Loads: Wait until the dishwasher is full before starting a cycle. Half-loads waste both water and electricity.
Use Eco Mode or Energy-Saving Cycles: Many dishwashers have a setting designed to save energy. These cycles might be a bit longer, but they use less electricity and water.
Opt for Air-Drying: If you can, skip the heated drying cycle and let your dishes air dry. Some models even have an air-dry setting, which reduces energy use.
A little maintenance goes a long way, too. Clean the filter regularly to ensure your dishwasher runs smoothly. This way, you won’t be paying extra for a dishwasher that’s working harder than it needs to.
