Oven Energy Calculator (Cost and kWh Usage)


When it comes to appliances, the oven is a staple in most households. Whether you’re baking a birthday cake, roasting a chicken, or simply reheating leftovers, the oven is a versatile tool that we rely on regularly. However, as with any appliance, there are costs associated with using it. In this article, we’ll take a closer look at the energy consumption and costs of using an oven, as well as provide some tips for saving money while still enjoying all the benefits of this handy appliance.


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:

The energy consumption of an oven can be quite high, as it requires a significant amount of power to heat up and maintain a consistent temperature. The default energy consumption for an oven is 2150 watts, which is higher than many other household appliances. To put this into perspective, a toaster typically uses around 800-1500 watts, and a microwave uses around 1000-1500 watts.

When you turn on your oven, the heating element uses electricity to generate heat, and the thermostat maintains a constant temperature by turning the element on and off as needed. The longer you use your oven, the more energy it will consume. Additionally, factors like the size of the oven, the food being cooked, and the initial temperature of the oven can all impact the energy consumption and efficiency of the appliance.

Why it’s important and relevant today:

The topic of energy consumption and costs is more relevant than ever, with concerns around climate change and rising energy prices. It’s important for individuals to be aware of their energy use and find ways to reduce it where possible. Additionally, reducing energy consumption can also lead to cost savings on monthly energy bills, which can be a significant benefit for many households.

Cost in Dollars of Energy Usage:

To calculate the cost of using an oven, we need to know the energy consumption (2150 watts) and the current energy price ($0.12/kWh). To determine the hourly cost of using the oven, we can use the following formula:

Hourly Cost = (Power in watts ÷ 1000) x Energy Price

Using the default values, we can calculate the hourly cost of using an oven:

Hourly Cost = (2150 ÷ 1000) x $0.12Hourly Cost = $0.258

To calculate the daily, monthly, and yearly cost of using an oven, we can use the following formulas:

Daily Cost = Hourly Cost x Hours Used

Monthly Cost = Daily Cost x 30 (assuming 30 days in a month)

Yearly Cost = Monthly Cost x 12

For example, let’s say you use your oven for 2 hours per day:

Daily Cost = $0.258 x 2

Daily Cost = $0.52

Monthly Cost = $0.52 x 30

Monthly Cost = $15.60

Yearly Cost = $15.60 x 12

Yearly Cost = $187.20

Money Saving Tips

  1. Cook multiple items at once – When you’re using your oven, try to maximize its use by cooking multiple items at once. This can help reduce the amount of time and energy required to heat up the appliance.
  2. Use smaller appliances for smaller tasks – If you’re just reheating leftovers or cooking a small meal, consider using a toaster oven or microwave instead of your full-sized oven. These appliances use less energy and can be more efficient for smaller tasks.
  3. Check the temperature – Make sure you’re using the correct temperature for the food you’re cooking. If the oven is too hot or too cold, it will require more energy to reach and maintain the desired temperature.
  4. Keep the oven door closed – Unless you need to check on your food, keep the oven door closed to prevent heat from escaping. Opening the door can cause the oven to lose heat and require more energy to maintain the desired temperature.
  5. Regular maintenance – Regularly cleaning your oven and checking for any issues can help keep it running efficiently. An oven that is dirty or has a faulty component may require more energy to operate properly.

By following these tips and being mindful of your oven use, you can save money on energy costs while still enjoying all the benefits of this versatile appliance.
