Cost Per KWH Calculator


About Cost Per KWH Calculator (Formula)

The Cost per kWh (Kilowatt-hour) Calculator is a tool used to determine the cost of electricity consumption based on the energy usage and the rate charged per kilowatt-hour. It helps individuals and businesses estimate their electricity expenses and manage their energy consumption. The calculation of the cost per kWh involves the following formula:

Cost per kWh = Total Cost / Total Energy Usage


  • Cost per kWh represents the cost of electricity per kilowatt-hour, typically measured in currency units (e.g., dollars, euros, etc.).
  • Total Cost refers to the total amount of money paid for electricity consumption during a specific period.
  • Total Energy Usage denotes the total amount of energy consumed, typically measured in kilowatt-hours.

To calculate the Cost per kWh, divide the Total Cost by the Total Energy Usage.

For example, if the total cost of electricity consumption is $500 and the total energy usage is 500 kilowatt-hours, the Cost per kWh would be:

Cost per kWh = $500 / 500 kWh Cost per kWh = $1.00/kWh

In this case, the cost of electricity per kilowatt-hour would be $1.00.

The Cost per kWh Calculator allows individuals and businesses to understand the unit cost of electricity and make informed decisions regarding energy consumption and utility expenses. It helps in comparing energy rates, evaluating the efficiency of electrical appliances, and managing energy budgets effectively.

It’s important to note that the cost per kWh can vary based on factors such as the energy provider, time of day, specific pricing plans, and any additional charges or taxes applied to electricity bills.
