How To Calculate Your Electricity Bill. Easy and simple Explanation.

How To Calculate Your Electricity Bill
A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill of the consumer if per unit rate is 9 (In INR ,Rs, $, DHR, or Riyal etc) [Take 1 month = 30 Days]Solution

1unit = 1kWh.

So Total kWh = 1000 x 24 x 30 = 720000 watts/hour

we Want to convert it into Units, Where is 1unit = 1kWh.
So total Consumed units. 720000/1000…… (k=kilo=1000)
Total Units = 720.
Cost of per unit is 9.
So total Cost or bill= 720 x 9 = 6480. (In INR,Rs, $, DHR, or Riyal etc)

[Also note that…why we multiply with 24 although the daily rate is given.. It is not Daily Rates...It’s the rate Per Unit...Where 1 unit = 1 kWh (Also Called 1 =B.T.U = Board of Trade Unit)... It means...If you switched on a 1000 watt bulb for 1 hour...It mean you consumed 1000 watts for an hour... (1000 watts for 1 hour = 1kWh = 1 unit of Energy) So if the rate of unit is 5 Dollars, then you will pay 5 Dollars as a bill for your bulb]

  1. 7201000/1000= 7201. not 720. Please correct it.

  2. 1000x24x30= 720000. Not 7201000

  3. this is a very useful site.<br />this site is very useful for us because we learn many things from this site.<br />thank you for this awesome post.<br /><a href="http://spidersilk.leapmaker.com/&quot; rel="nofollow">technology</a>

  4. good explanation but my doubt if my total consumption is 250 units then i am paying 250*4=1000 Rs. does it mean cost of 250kW is 1000Rs if my question is wrong then what is the total amount of the palnt spendng on me to supply 250 units in a month?

  5. Thanks for sharing this calculation on the <a href="http://www.torchenergy.com/s/average-electric-bill-for-apartment&quot; rel="nofollow">Average Electric Bill</a>. I was finding it difficult to understand how the bill is calculated, based on the consumption of electricity.

  7. Man braucht keine Befürchtungen bezüglich dieses Prozesses. Es ist extrem sicher und man ist der Beste, was es ist gewährleistet. Der Vergleich Portal <a href="https://www.prioenergie.de/gaspreisrechner&quot; rel="nofollow">https://www.prioenergie.de/gaspreisrechner</a&gt; kümmert sich um den gesamten Prozess der Schalt-und sorgt dafür, dass der Übergang reibungslos funktioniert.

  8. As per your statement &quot;A consumer consumes 1000 watts daily for one month&quot; so that equals to 1000W *30 =30000 W hence 30kwh, <br />If your statement was &quot;A consumer uses 1000W bulb (power consumption for electrical appliances is mostly stated in watt h) for 24hrs/ day for a month of 30days. then ur calculation 1000 x 24 x 30 = 720000 watts/hour is right.<br />

    • Hello Rohit sir.. here in that Question we can lighted that bulb in only 1 hour na… then how u calculated that total hours(24 hrs) .. 1000x24x30.. in that Multiplication it not comes to 24hrs i think. bcoz we can lighted only 1 hour na…. please solve my Confusion … my problem is linked with other questions also… :( :(

    • Dear Karthik @<br />Check the Question as&quot;A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill&quot;<br />So 1000W/h daily = 1000W/h x 24….(As daily mean = 24 hrs in a day.)<br />That&#39;s why we have multiplied it with 24.

  9. i&#39;m fully confused… Why u multiply with 24 hrs (1000x24x30) … in that Question 1000 watts load per hour daily for one month.. it means we can loaded that bulb in 1 hour Only in total 30 days na… that bulb not loaded 24 hours only in one hour… then why u multiply that 24hrs.

    • 1000Watt per hour Daily = 1000W/h x 24<br />Check the Question as&quot;A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill&quot;<br />So 1000W/h daily = 1000W/h x 24….(As daily mean = 24 hrs in a day.)<br />That&#39;s why we have multiplied it with 24.

    • Ohhh okay Thank u ET…. in that question load per hour daily for one month,,, but i want i&#39;m consumes 1 hour only in whole day for One month then how much units we can consumed…

    • If you mean 1000Watt only for One hour daily (take 1 month = 30 days)<br />the,<br />1000W x 1Hr x 30 Days = 30000WH = 30kWH = 30Units

    • Oh Nice Thank u ET.. now totally gone Confuse.. thank u very Much.. if Diff Diff watt bulbs and Heaters are using in 3, 4 hours how to calculate… Hey in this site is thier any Electrical Calculator as per India, AP Units and Tariff.

    • In case of Different load…. Add all those loads and usage per hour…then multiply with 30 , if you want to find the electric bill for 0ne month.

  10. It&#39;s an amazing piece of writing in favor of all the web visitors; they will get benefit <br />from it I am sure.<br /><br />Feel free to surf to my web site; <a href="http://burnmyfats.wordpress.com&quot; rel="nofollow">weblink</a>

  19. I was confused about my electric consumption. This site helped me,thanks.

  20. how do the sebs calculate for load in 3 phase – do they average out on each phase in meter.. for eg. R phase 3 amps , Y phase 5 amps and B phase 6 amps single phase load, then do they average on each phase of a 3 phase meter ?? and then calculate average power for 3 phase?? please clarify

  21. this site is very useful to me.thank you for your ans

  22. my bill is 1185/- units are 245 is it correct bill, how to caluclate please reply.
