How to Calculate Electricity Bill

Electric bill readings are done manually in Pakistan, even in this time and age. And since meter reading is a manual activity in Pakistan, it is prone to discrepancies and human errors. To avoid this some people like to keep a day to day check on their meter readings and calculate the bill beforehand, this also helps keeping your electricity usage balanced.

To calculate your electric bill, you’ll need to figure the energy usage of each of the appliances and electronic devices in your home. In an ideal world, estimating your electricity usage would be as easy as looking at an itemized grocery receipt. You’d be able to see exactly what you spent to run the dishwasher, do the laundry, watch TV and use a month’s worth of hot water. That technology is getting closer every day, but if you want to get an appliance-by-appliance breakdown right now, you’ll need to do a little math.

Electric Consumption

Electricity consumption is measured in terms of the number of units of electricity that your household has expended in a billing period which is usually one month. Your electricity meter outside your house provides a reading for the number of units consumed at any given point in time. Usually the reading states the total consumption from the date of installation of the meter. In Pakistan meter reading is a manual process carried out by various meter readers that are designated for different areas of cities. The meter reading date is usually listed at the top of the electricity bill. Along with the meter reading date are the current billing month, issue date and due date. Please note that the electronic version of the bill or WAPDA online bill is usually available a few days before the printed version is delivered to houses.

Electricity Bill

It is recommended that the electricity consumption listed on the bill is verified by checking the meter yourself around the usual meter reading date for your house to ensure that there are no inconsistencies. If you notice that there is a significant difference between the actual and reported readings, notify your sub division officer (SDO) at the local electric supply office immediately. The contact information for your SDO is also listed on your electricity bill. Additionally, if you notice a spike in your unit consumption or cost of electricity, compare it with your consumption in the previous year in the same months. This information is available in the billing history columns of your electricity bill.

To calculate the monthly unit consumption of a household, a meter reader subtracts the current month’s reading with the previous month’s reading. The current month and previous month’s units are present in all the WAPDA bills supplied in Pakistan.

Calculations

1 unit = 1 kWh.

So Total kWh = 1000 Watts x 24 Hrs x 30 Days = 720000 watts/hour.

We want to convert it into Units, Where is 1 unit = 1 kWh.

So total Consumed units. 720000/1000…… (k=kilo=1000).

Total Units = 720.

Average Cost of per unit is 15.

So total Cost or Electricity bill= 720 x 15 = 10800. This was the method to calculate your electricity bill. Alternatively, you can also calculate your bill by visiting LESCO Official website, click here to calculate.
