How to Use Online LESCO Bill Calculator

To estimate bills using the LESCO bill calculator, you should input the following information in the online Bill Calculator.

Meter Reading

Input the meter reading from your previous bill or the current reading on your meter.

Rate Per Unit

Provide the rate per unit, as indicated on your bill (typically in Rs/kWh).

Total kWh Consumed: Calculate the total kilowatt-hours (kWh) consumed for the specified period (e.g., for a monthly electricity bill, select 30 days and multiply the values mentioned above to determine the total kWh used).

LESCO Bill Calculation Formula

The LESCO bill calculation formula is:

Monthly Electricity Bill = Watt Hours x Price per Kilowatt Hour (kWh)

LESCO Bill Calculation Method

Since 1 unit is equivalent to 1 kWh, 

The total kWh can be calculated as follows: 

1000 W x 24 Hours x 30 Days = 720,000 watt-hours. 

To convert this to kWh, simply divide 720,000 by 1000, resulting in 720 kWh

The total monthly average consumption amounts to 720 kWh. With an estimated unit cost of approximately 20 PKR, you can calculate the total cost using the formula provided above:

                                       Monthly Electricity Bill= 720*20= 14400

Therefore, the approximate monthly bill average would be 14400.

Bonus Tip – If you’re a non-filer consumer, a 7.5% tax is added to your bill every month, resulting in an increase in your electricity bill. To confirm whether this 7.5% tax amount has been added to your bill or not, you can verify your CNIC (Computerized National Identity Card) at PITC (Power Information Technology Company). Visit the official website of PITC and update your CNIC in the required fields.
