Dishwasher Energy Calculator (Cost and kWh Usage)


Dishwashers have become a common household appliance throughout the world. They make it easier and efficient to clean dishes, as opposed to the traditional method of manually washing dishes. However, with the rising cost of energy, it is important to understand the energy consumption and costs of using a dishwasher. In this article, we will explore the energy consumption and cost of using a dishwasher, and provide some money-saving tips to help you save money on your energy bills.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

Dishwashers use electricity to heat water, run motors, and power the various features of the machine. The amount of energy used by a dishwasher depends on various factors like the size of the appliance, the type of dishwasher, and the age of the machine. Modern dishwashers are designed to be more energy-efficient than older models, but they also come with more features that consume more energy. The average dishwasher uses around 1200 watts of power.

To help illustrate the concept of energy consumption, let’s take a look at this example: If you run your dishwasher for an hour, it will use 1.2 kWh of electricity. This is equivalent to running a 100-watt light bulb for 12 hours.

Importance and Relevance

Understanding the energy consumption and cost of using a dishwasher is important because it can help you make informed decisions that can save you money. By being aware of how much energy your dishwasher uses, you can take steps to reduce your energy consumption and save money on your energy bills. Additionally, reducing your energy consumption can have a positive impact on the environment by reducing the amount of greenhouse gas emissions that are released into the atmosphere.

Cost in Dollars of Energy Usage

The cost of using a dishwasher depends on how much energy it consumes and the cost of electricity in your area. In this article, we will use the default energy price of $0.12/kWh to calculate the cost of using a dishwasher.

To calculate the cost of using your dishwasher, you can use the following formula:

Cost = Power x Time x Energy Price

Let’s take a look at some examples to help illustrate this concept:

  • Daily Cost: If you run your dishwasher for one hour per day, the daily cost would be: 1.2 kWh x $0.12/kWh = $0.14/day
  • Monthly Cost: If you run your dishwasher for one hour per day for a month (30 days), the monthly cost would be: 1.2 kWh x 30 days x $0.12/kWh = $4.32/month
  • Yearly Cost: If you run your dishwasher for one hour per day for a year (365 days), the yearly cost would be: 1.2 kWh x 365 days x $0.12/kWh = $52.56/year

Money Saving Tips

Here are some money-saving tips that can help you reduce the energy consumption and cost of using your dishwasher:

  • Wait until your dishwasher is full before running it. Running a half-full dishwasher wastes energy and water.
  • Use the energy-saving or eco-mode settings on your dishwasher. These settings use less energy and water to clean your dishes.
  • Scrape your dishes instead of pre-rinsing them. Pre-rinsing your dishes wastes water and energy, and modern dishwashers are designed to clean dishes without pre-rinsing.
  • Use the air-dry or heat-dry settings sparingly. The heat-dry setting uses a lot of energy, and the air-dry setting can take longer to dry your dishes. Consider opening your dishwasher door to let your dishes air dry instead.
  • Keep your dishwasher well-maintained. Regularly cleaning your dishwasher can help it run more efficiently and reduce energy consumption.

By following these money-saving tips, you can reduce the energy consumption and cost of using your dishwasher. These tips also help you do your part in protecting the environment by reducing your carbon footprint.
