Electricity Saving Tips For Homes And Offices

Online Electricity Bill Calculator – For all states in India

By on September 26, 2014

For most of us, electricity bill is needed just to check the final amount and make the payment. We at Bijli Bachao asked a lot of our acquaintances about how much they understand their electricity bills, and we found hardly a handful who did understand it. And in spite of understanding the bills, not many knew how much they are spending per unit (or 1 kWh) of electricity.


It is very important to know the per-unit cost of electricity as it helps us in understanding how much we are spending per appliance at our home. It is important to understand the monetary impact of any electricity efficiency measure we take. It is also important to understand various components of electricity bills and what is their contribution to the total electricity bill. In a bid to help people understand the same, we have created this online electricity bill calculator that will help people understand how much they spend on various appliances every month and how they can save by doing various activities. Please make sure that you read about the calculator below before using it.


Please note that this tool currently works only for domestic tariffs.


Enter the information below from your electricity bill

Steps to use the tool:

1) Select Utility: Once you login, the first thing you need to do is select utility. Select your state, district and utility and the system saves your information for the user session automatically.

2) Enter Units: Enter this value as shown on your electricity bill. This shows up as units consumed.

3) Select Phase: Select if you have a three phase connection or single phase connection. This information is also available on the electricity bill.

4) Connected Load: It is decided by the utility based on appliances you have at your home, please see our article on connected load to get more details.. It is also mentioned as sanctioned load, load, connected load, or approved load. If the load mentioned is in Watts (it is a number is 100s or 1000s) then divide it by 1000 and enter it.

This calculator will help you:

1) Understand various components of your electricity bills.

2) Understand how much you are paying per unit (1 kWh) of electricity bill.

3) Understand how much you spend on various appliances like lights , air conditioner , refrigerator ,  tubelight , computer , set top box , fan , etc. Please note that we have taken approximate usage of these appliances based on how it is used normally in houses. Actual amount may vary as per your use. The values are just a representation.

4) Understand savings if you switch from inefficient to efficient appliances. Even these values are approximation based on general usage. We are in process of building tools to help you get to better values as per your consumption in future.

The tool has been built with latest tariff data available from all the state electricity boards in India and has maximum information as available on internet and through our contacts who helped us with sample electricity bills from various states. Certain values have been rounded to have better readability and so it may not match exactly to your electricity bills but will be very close.

The tool covers following bill components:

1) Energy Charge: This is the per unit electricity charge that you pay on your bill. It is mostly defined slab wise and the cost increases as units on electricity bill increases.

2) Fixed Charge: This is mostly dependent on the connected load that the utility provides you. Connected load is typically calculated as sum of wattage of all the appliances that you have at your home. The utility allocates this much amount of electricity for your home and that is why the fixed charge is applicable.

3) Electricity Duty & Tax: This is the government tax for using electricity. Duty is applicable per unit of electricity consumption and tax is applied on the whole bill amount.

4) Meter Rent: Rent that you pay for having meter at your home. Rates are different for single phase and three phase connections.

5) Wheeling Charge: The tool also helps you find out how your bill gets impacted if you move from Reliance Energy to Tata Power in Mumbai. Wheeling charges are applicable for the switchover.

6) Minimum Monthly Charges: In some states if the consumption is less than a certain amount, minimum monthly charges are applicable, which means that the bill amount cannot be less than minimum monthly charges.

The tool does not cover following elements:

1) FAC (Fuel adjustment charge) or FCA (fuel cost adjustment) or FPPCA (Fuel and Power Purchase Cost Adjustment): This is the amount which utilities apply on bills based on varying price of fuel or Coal. Every month this value is different and is derived based on the current cost of Coal. Typically this a few paise per unit.

2) Arrears/Interest and Other Charges: If your electricity bill has old payment pending and interest on the same, or any other charges, then those will not match from the output of the tool to your electricity bill.

The tool currently in beta stage works only for:

domestic LT (Low Transmission) connections with a connected load between 0 and 20 kW and has been validated for following states: Andhra Pradesh, Assam, Bihar, Chandigarh, Chattisgarh, Gujarat, Haryana, Karnataka, Kerala, Madhya Pradesh, Maharashtra, New Delhi , Rajasthan, Tamil Nadu, Uttar Pradesh and Uttarakhand. It also contains information for following states but has not been validated: Arunachal Pradesh, Goa, Himachal Pradesh, Jammu and Kashmir, Jharkhand, Manipur, Meghalaya, Mizoram, Nagaland, Odisha, Punjab, Sikkim, Tripura and West Bengal. Please feel free to play around with the tool and provide feedback to [email protected]

    Hi Abhishek,

    This is Lakshmi from Chennai. I am planning to install a solar pv panel for my residential purpose as my EB bill is rising exhorbitantly. I need your suggestion whether it is advisable to switch over to solar energy and whether it will bring down my power cost considerably. At present my bi-monthly energy consumption is around 900 units and i am paying around Rs. 4700.00 to EB. Pls advise if 1 KVA solar panel is sufficient to support my current consumption. How much will be my cost savings by adopting solar energy and within how many years can i recover my investment in solar unit ( net of govt. subsidies ) Are there any hidden features in solar power system for domestic users like me and if so pls highlight them. What is net metering and how does it work. I read that surplus energy can be transmitted to EB for which we will be re-imbursed. Pls explain this concept and whether it is beneficial for us. In general please add your other comments you may like to offer with regard to solar power system for domestic users thanks

  6. Anjum says:

    Hi Abhishek, I wanted to know about the unit consumption of samsung refrigerator model no. RR21J2415SA/TL/2015 per month. it runs 24*7.

    • Abhishek Jain says:

      Hi Anjum,
      Samsung refrigerator model no. RR21J2415SA/TL/2015 consumes 208 units/yr. Therefore it consumes 17.33units/month. This data’s are under test condition and typically a standard refrigerator consumes 30% more electricity in regular usage.

      • Anjum says:

        Thank you Abhishek for such a prompt reply!!! I have one more doubt. I have purchased this refrigerator 8 days ago. and the meter reading is 19 unit in this short span only. This refrigerator runs 24*7. other than that i uses one fan- 15hrs, one tubelight-8 hrs, two cfl (25watt)-2hrs. Is my electric meter is running fine? I think there is some serious problem with the reading.

        • Abhishek Jain says:

          Hi Anjum,
          According to our calculation the units consumed by the appliances you have given is 2.6 units/day. So for 8 days it is 20.8 units. So your meter is working fine.
          You can look at these table to see the units consumed by your appliances per day.

          Appliances Wattage Usage in hours Units/day  
          Fan 90 15 1.35  
          Tubelight 50 8 0.4  
          2 cfls 50 2 0.1  
          Refrigerator   24 0.75  
              Total 2.6

    I recently shifted to a new place in gurgaon my current month usage is 36 units. I have 3 phase connection with 6 KW sanction load. How much do you expect the bill to be?

    awsome app

  10. anand says:

    is electric sub meter legal to install in house built to provide 9 rooms to students on rent,

    • Abhishek Jain says:

      It is legal to put submeters if you are giving rooms on rent. The electricity distribution company will collect bill only for one main meter. You will have to divide it and collect bill from your renters yourself.

    calculation is not happening in this site.

    • Abhishek Jain says:

      Hello Mr Sivaram,

      What are the values that you are selecting in the calculator? If you can let me know then I can calculate and send the calculation to you. The calculator uses Javascript and if javascript is blocked on your browser, the calculator will not work.

    • Abhishek Jain says:

      Rs 400 for LED sounds high. How many units consumption does your electricity bill shows? Price of electricity can be found on: https://www.bijlibachao.com/news/domestic-electricity-lt-tariff-slabs-and-rates-for-all-states-in-india-in-2014.html

    1)What are the duties of a meter Reader while reading,???
    2) what is the time period of checking meter by power suppliers??

    • Abhishek Jain says:

      Hello Ms Agarwal,

      Reliance Energy has monthly billing, so they should check meter every month. As for other things I would suggest to read this report (if it can be helpful): http://www.prayaspune.org/peg/2013-02-21-09-18-33/item/download/118_341560a5872ca7743a629e31b524576f.html

  15. kuldeep says:

    if i have more than one meter in my house than regulatory surcharge and energy tax will be charged separately for all or combined for all

    • Abhishek Jain says:

      That is right, it will be charged on every meter. Every meter will have its own bill and regulatory surcharge and energy tax is on the bill.

  16. ravindra patidar says:

    1 unit(1kwh) = how much cost (in Rs)

    • Abhishek Jain says:

      Hi Ravindra,

      It will depend on your location (city/state) and your usage. Electricity rates are slabbed, i.e. if your usage is less the cost per unit will be less, if your usage is more, cost per unit will be more.

  17. narendra says:

    How many units are consumed per hour by 32 and 42 inch lcd tv of LG

    • Abhishek Jain says:

      32 inch LCD should be about 100 watts and 42 inch about 130-140 watts. So a 32 inch would consume 0.1 units in an hour and 42 inch would consume 0.13 units.

  18. Rushabh says:
