Enter the annual electricity usage (kWh) and the average cost of electricity ($/kWh) into the Average Monthly Electricity Bill Calculator. The calculator will evaluate and display the Average Monthly Electricity Bill. 

Average Monthly Electricity Bill Formula

The following formula is used to calculate the Average Monthly Electricity Bill. 

AEB = AEU * ACE /12
  • Where AEB is the Average Monthly Electricity Bill ($/month)
  • AEU is the annual electricity usage (kWh) 
  • ACE is the average cost of electricity ($/kWh) 

To calculate the average monthly electricity bill, divide the total yearly bill by 12.

How to Calculate Average Monthly Electricity Bill?

The following example problems outline how to calculate Average Monthly Electricity Bill.

Example Problem #1:

  1. First, determine the annual electricity usage (kWh).
    • The annual electricity usage (kWh) is given as: 70,000.
  2. Next, determine the average cost of electricity ($/kWh).
    • The average cost of electricity ($/kWh) is provided as: .15.
  3. Finally, calculate the Average Monthly Electricity Bill using the equation above: 

AEB = AEU * ACE /12

The values given above are inserted into the equation below and the solution is calculated:

AEB = 70,000 * .15 /12 = 875.00 ($/month)


Example Problem #2: 

For this problem, the variables needed are provided below:

annual electricity usage (kWh) = 10,000

average cost of electricity ($/kWh) = .50

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

AEB = AEU * ACE /12 = ?
