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

  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]

    3. Dear Karthik@
      Vinod have corrected the above calculation...as 1000x24x30=720000...but mistakenly, we had written 7201000 instead of 720000. That's why you are confused.

    1. Yes! If your consumed Units are 250 [250kWh] and your bill is Rs. 1000, then your are paying Rs. 4 per Unit Electricity.

  5. Thanks for sharing this calculation on the Average Electric Bill. 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 https://www.prioenergie.de/gaspreisrechner kümmert sich um den gesamten Prozess der Schalt-und sorgt dafür, dass der Übergang reibungslos funktioniert.

    As per your statement "A consumer consumes 1000 watts daily for one month" so that equals to 1000W *30 =30000 W hence 30kwh,
    If your statement was "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.

    2. Dear Karthik @
      Check the Question as"A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill"
      So 1000W/h daily = 1000W/h x 24....(As daily mean = 24 hrs in a day.)
      That's why we have multiplied it with 24.

  10. i'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.

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

      Delete
    3. If you mean 1000Watt only for One hour daily (take 1 month = 30 days)
      the,
      1000W x 1Hr x 30 Days = 30000WH = 30kWH = 30Units

    4. 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.

    5. 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.

    Sir, Energy using in Telecom Towers with 3Phase s/m LT service. Each phase drawing 16A, 12A, 12A respectively. Load is static. How to calculate the avg.units per day/month/bimonthly. CT ratings 20A each phase. Trivector energy meter installed.

  15. No Doubt This Calculation makes to save electricity but to avoid this calculation in my opinion Low Voltage Led Lighting is good option that saves 70% to 80% of Electricity.
