Step by Step Guide: Electricity Bill Cost

Step#1: Identify your billing date. This is the period that your meter is read.

Example: 04/May/2020 – 05/June/2020

Step#2: Write down the previous meter reading and the present meter reading based on the billing date.

Example 04/05/2020: 6017 – 05/06/2020: 6160

Step#3: Calculate the units by subtracting the present reading from the previous reading to determine how much electricity units were used.

Example: (present reading) 6160 – 6017 (previous reading) = 143KW units

Step#4: Determine whether you are a domestic or commercial customer

 

Domestic Customer Calculation

  Block 1: first 75 units @ 0.48c

  Block 2: all remaining units @ 0.55c

  Fuel Surcharge: total units @ fuel surcharge rate

Example:

  Block 1: 75 units @ 0.48c = $36.00

  Block 2: 68 units (143-75 units) @ 0.55c = 37.40

  FS:        143units @ 0.72c (variable cost) = 176.36

Commercial Customer Calculation

  Block 1: all units @ 0.48c

  Fuel Surcharge: total units @ fuel surcharge rate

Example

  Block 1: 143 units @ 0.54c = $77.22

  FS:        143units @ 0.72c (variable cost) = 102.96

 

 

Step#5: Total each cost to determine your monthly electricity charges.

Example: $ (36+ 36.2+ 102.96) =$175.68 Domestic charges

Example: $ (77.22 102.96) =$180.18 Commercial charges
