Is electricity a fixed cost

It can be either a fixed or a variable cost

As a fixed cost

A fixed cost is one that will not vary due to a change in production volumes or just volumes of a product in general. When electricity is charged at fixed cost for the plant or premises then it can be termed fixed cost. This is because no matter how many products you will sell or produce, the cost of electricity will not change.

As a variable cost

A variable cost is one that varies or changes with the change in production volumes or sales volumes. When electricity is charged due to the consumption then its value will change with the volumes sold or produced therefore is treated as a variable cost
