The electricity usage of an oven depends on how much power does it use.

Depending on the model, an oven can use between 2000 and 5000 watts. So, if you want to calculate the electricity usage and the electricity cost of your oven you need to find out the exact power consumption of your model.

- How much electricity does an oven use? -

Electricity usage of an oven

The power consumption of your oven should be described on the specification’s manual it came with.

Alternatively, if you are considering to buy a new oven, the wattage can be found on the internet by browser search. Just browse for the oven model followed by ‘wattage’ or ‘ power consumption’.

Electricity usage and cost calculator

Once you know the power consumption, the calculator below can be used to estimate the power consumption and the electricity cost of an oven over a period of time.

You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.


For example, if your oven:

  • It has a power rating of 3000 Watts (3 kWh)
  • You use it 2 hours per day for 100 days per year
  • You are paying 0,217 euro (or dollars or pounds) per every kWh you consume 

You will be paying around 130 euro (or dollars, or pounds, or…) per year in electricity costs.

Still, if you want to know the exact electricity usage of your microwave oven, you need to use a plug-in power meter.

For more details, have a look to this post that we have created to show you how to use a plug in power meter to measure your appliances and devices power consumption.

Additional information

Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would learn more about them, have a look to this video that we have prepared for you.

If you think that your oven it is using too much electricity, here there are four simple ways to reduce the power consumption of an oven:

1.- Buy a self cleaning oven

The self cleaning ovens have better insulation which makes them more efficient. 

This means that it will use less electricity than other ovens without this functionality.

2.- Buy a convection oven

The convection ovens have a fan that continuosly circulate the hot air thorugh the oven. This allows to cook the food quicker and a lower temperatures. 

This kind of oven will cook the food quicker and at lower temperatures which can save up to 20% on electricity.

3.- Inspect the gaskets

Over time, the gaskets may deteriorate allowing the heat to escape. This will lead to longer cooking periods and an increase on the eletricity usage.

4.- Give your oven space

The ovens need airflow. Most probably when your oven was installed enough space was left empty below or behind your oven to allow the necessary airflow. Make sure that don’t let clutter build up so your oven can perform efficiently. 

Electricity conservation - Save and conserve energy

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment

The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few watts here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.


For example, if 9000 households would manage to save as little as 10 Watts per hour (0,01 kWh) worth of electricity per day, that would add to 32850 Kilowatt hour (kWh) per year. 

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

  • Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) we would collectively be saving nearly 6000 euro per year.
  •  To produce 32850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
Have a look to this page for more information about the amount of resources needed to produce electricity.

In any case it is clear that small energy savings do really count when looking into the bigger picture.
