EASY STEPS FOR EVERY HOME

How to check your bill

Keep your electricity bill with you. Then follow these steps.

01
Choose your bill dates
- Open Calculator.
- Find the start and end dates on your bill.
- Enter them in From and To below the page heading.
- The calculator counts the days for you.
- Optionally enter Rate per unit (Rs) beside the dates. Your estimated energy costs update using this rate, excluding taxes and fixed charges.
02
Add items used at home
- Tap an appliance you use in the left list, such as Ceiling fan.
- Enter its details in the middle panel: tap Edit, then enter values and tap Save appliance.
- A units badge then appears beside its name. Only saved appliances count in your home total.
- No badge means the appliance is not included. Tap the trash icon beside it to remove it from the list.
- Use Add appliance for other items. Enter a name in the middle panel.
- Power (watts): Look for a number with “W” on the item’s sticker. Enter that number.
- How many? Enter the number of these items in your home.
- Hours each day: Enter how many hours you use each item in a day.
- Days used: Enter how many days you used it during this bill period.
- Add all items, including your water pump.
03
Check the starting numbers
- Faint text inside an empty field is an example, not a saved value. Type your own details.
- If you do not know the watts, ask someone to help you check the sticker.
- A fridge or AC does not use full power all the time.
- Use Average power level to allow for changes in power. 50% means half the entered watts on average during the switched-on hours.
- For a fridge or AC, read the guidance shown with that appliance. The percentage must be entered explicitly.
- For ordinary steady-use appliances, a blank percentage means 100%. For an AC or fridge, enter a percentage: use 100% if your watts already represent average use, or a deliberate estimate if you entered label watts. Your result is an estimate.
04
Enter units from your bill
- Find the units used on your bill. They may be written as kWh.
- Enter them in Billed electricity units. Do not enter rupees.
- The appliance preview updates as you type. Tap Save appliance to update your home total.
- If you change a saved appliance, save it again to update its badge and total.
- On a phone, your total stays at the bottom. Tap Bill & comparison to enter your bill and save the result.
- +40 units means your bill shows 40 units more than the estimate.
- −40 units means your bill shows 40 units less than the estimate.
- You can also enter your old and new meter readings. This is optional.
05
Save a record each month
- Tap Save comparison.
- Open History to see your saved bills and differences.
- Your records stay in this browser on this phone or computer.
- In History, tap Download backup to keep a copy.
- Use Restore backup to bring that copy back, or move it to another device.
- Clearing browser data may remove your saved records.
06
Ask for a bill check
- First, check your dates, meter number and meter readings.
- Check that you added all items and their correct use times.
- If you still have a concern, tap Download complaint summary.
- Add your name, address and consumer number to the downloaded file.
- Send it with your bill copy and dated meter photos to your electricity billing office.
- Use the contact details on your latest bill. This website does not send the complaint for you.

Please remember

This calculator gives an estimate, not an exact meter reading. A difference does not always mean the bill is wrong.
A unit measures electricity used. For example, a 1,000-watt heater used for 1 hour uses 1 unit.
If you have solar panels or batteries, this estimate includes electricity they supply too. Your bill may show only electricity taken from the electricity company.
This free calculator is provided by Renascence Labs for residents of any city or community, including Bahria Town. It is independent of electricity providers and community management.
