Kwh Per Month Formula

The following formula is used to calculate the kilowatt-hours per month for a given power, hours used per day, and days used per month.

kWh = P * h * d

Variables:

  • kWh is the kilowatt-hours per month
  • P is the power in kilowatts
  • h is the hours used per day
  • d is the days used per month

To calculate the kilowatt-hours per month, multiply the power in kilowatts by the hours used per day and then by the days used per month.

What is Kilowatt-hours per Month?

Kilowatt-hours per month (kWh/month) is a measure of energy consumption over a month. It represents the total amount of electrical energy used by an appliance or a system over a month. This metric is commonly used in electricity billing and energy management to quantify the energy usage of households, businesses, and industrial facilities. By understanding kWh/month, consumers can better manage their energy consumption and potentially reduce their electricity bills.

How to Calculate Kilowatt-hours per Month?

The following steps outline how to calculate the Kilowatt-hours per Month.


  1. First, determine the power in kilowatts (P).
  2. Next, determine the hours used per day (h).
  3. Next, determine the days used per month (d).
  4. Finally, calculate the Kilowatt-hours per Month using the formula kWh = P * h * d.
  5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Power in kilowatts (P) = 2 kW

Hours used per day (h) = 5 hours

Days used per month (d) = 30 days
