**How To Calculate Your Electricity Bill? Simple Calculation.**

It is very easy to calculate the **electricity bill** and tariff for Electrical Engineering Students but, it makes confusion for non-technical people that concern about their electric charges from the electricityΒ service providers.

Below is a simple example and calculation about electricity bill. If you pick this, You will be able to calculate your electricity bill very easily.

**Example:**

*Suppose, 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 $, Β£, β¬, INR ,Rs, DHR, Riyal etc) [Take 1 month = 30 Days].*

**Solution: **

1unit = 1kWh.

So Total kWh = 1000 Watts x 24 Hrs x 30 Days = 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 Electricity bill= 720 x 9 = 6480. (In $, Β£, β¬, INR ,Rs, DHR, Riyal etc). You have Done π

A question is raised that why we multiplied it with 24 although the daily rate is given. Not that It is not Daily Rates, Itβs the rate of Per Unit Where 1 unit = 1 kWh (Also Called 1 =B.T.U = Board of Trade Unit).

for instance, If you switched ON a 1000 watt bulb for 1 hour, It mean you consumed 1000 watts for an hour i.e. (1000 watts for 1 hour = 1kWh = 1 unit of Energy). So if the rate of unit is $5 , then you will pay 5 Dollars as a bill for your bulb which consumedΒ 1kWh = 1 unit of electricity.

Isn’t it easy to calculate you electricity bill?… Let me know in the below comment box if you face any problem regard your **electricity bill calculation** or want to know more about your costume (home, residential or commercial electricity bill.

Thanks Dear..it was calculator error..

Hellooo Vinod Sir how u Get that 7201000… 1000x24x30=720000 na… than how u get that 7201000 .. again nxt comment u said that 1000x24x30=720000 … i'm fully confused about u r comment please explain me…. Vindos sir and Electrical Technology

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

If I use 2000 watts otg for 1hr with the unit rate of rs.9 then what is the cost for that 1 hr??

DEAR SIR I AM USING GRILL SANDWICH MAKER 1500 WATT 1 HOUR PER DAY SO WHAT IS MY MONTHLY CONSUMPTION?

hi what will be the formula for 3 phase

1000x24x30= 720000. Not 7201000

Thanks Dear..it was calculator error..

hellow sir,<br />i am subbu….i am using commercial. i am using 1 laptop and 1 fan and 1 florescent lamp … 1 unit per cost 7 rupess..<br />how is to calculte per month<br /><br />ssraj217@gmail.com

for how long??? i.e, how many hours u using these appliances in a day…

1000*24*30/1000=720units

Sir

Hume kisi chej ka 1hour ki unit nikalni ho to kaise nikalte h

1000 watts daily for one month (24 hrs) .. 1000w 24hours 30 days (1000wx24hx30d) =units 720

1000*24*30/1000=720units

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/" rel="nofollow">technology</a>

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?

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

Plz what is one unit charge in Jaipur

It depends on your service provider (different charges are applied in different countries and locations).

In addition, the per unit charges are also mentioned in your electricity bill (In most cases).

simpel formula is E=PT

Only for this post…..but not apply on three phase and other load calculations

DEAR WHAT WILL BE THE FORMULA FOR THREE PHASE PLEASE.

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

Agree…

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… π π

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

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.

1000Watt per hour Daily = 1000W/h x 24<br />Check the Question as"A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill"<br />So 1000W/h daily = 1000W/h x 24….(As daily mean = 24 hrs in a day.)<br />That'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'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.

It'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" rel="nofollow">weblink</a>

if i have 100 watt bulb and it is usage 3 hr per day in a month how does it calculate

100 x 3hrs x 24 hrs

and then divided by 1000

No I think 100Γ3hrsΓ30days then devided by 1000

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

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

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

how to caluclate the electricity bills? my bill amount is 1185/- unts are 245 is correct rate.

sir i m using 0.5hp single phase motor every day minimum 3hrs running and 6.39paisa/unit cost .what is the monthly consumtion of this pump .please send me calculation details

0.5*746=373w

373/1000=0.373kw

total units=0.373*3*30=33.57units

33.57*6.39=214.5123

ur mntly conusmption=214.5123

why you multiply 746 with 0.5. as we know motor is 0.5hp. kindly confirm

@Anna… As you know that, there are 746Watts in 1hp….

Therefore, To convert the 0.5hp into watts,,, That’s why they multiplied with 746Watts….

I used to be able to find good info from your blog articles.

if we on 70 hp mtor how much units its take

hello sir, i have one ice cream machine, it consume 1.1 kw per hour, so what is a calculation of per day,and how much unit i used in 1 hour and what is a amount of it,

please give me a suitable reply,

Sir i’ve got a laptop that I use 1hr daily for charging what’s the total unit sir

It is very useful for everyone it helped me a lot

Thank you.

unit calculation

How to calculate electricity cost for private educational institutions in Tamilnadu. As i refered in tangedco website, the following tariff details were given,

for private educational institutions, Demand charge in Rs/KVA/Month – 350 , Energy charge in Paise per kwh – 635.

While i checked with online calculator of tamilnadu electricity board,

it is asking for contracted load, consumed units and kvah. contracted load is the load specified in the agreement between consumer and licensee. Why are they using kvah for calculating energy cost? By using kVAh and Kwh and contracted load, how they will calculate energy cost?

Can u give me an example for calculating?

If you could give me your ideas for this, it will be helpful for me.

Dear, There are lots of way to charge the consumer for used electrical power. i.e. Two part tariff, Max demand Tariff , Three Part tariff, Power factor tariff and block rate tariff etc. But they charge for the exact kWh… So please tell me the total number of consumed unites and the price per unit. Thanks

Dear sir, This is were I am confused. I downloaded the tariff details of Tamil Nadu from internet. For domestic consumers, it is given like, for first 100 units a particular rate and for next 100 units a particular rate and so on. But for other tariffs like private educational institutions, it is given as,

Demand charge in Rs/KVA/Month β 350 , Energy charge in Paise per kwh β 635. (Rs.6.35 Per unit)

And when i checked the online calculator of tangedco website, for the calculation of domestic consumers, it asks only the number of consumed units. If we enter the consumed units, it wil automatically calculate and give the output of the electricity bill.

But for Private educational institutions, it asks for consumed units, Kvah and contracted load. So as per you asked, lets take the example of 10,000 units consumed and Per unit cost as mentioned above as Rs. 6.35.

Please let me know why they given the information of demand charge , and contracted load. How to use that for calculating energy cost?

please calculate total bill in INR of 100unit, 200unit &500unit

Dear sir,i used 100 kWh for 1 month and per unit i pay RS 4.so how much will the bill comes at the end of month?

Simply, 100 x 4 = 400Rs … (Without Taxes and other charges)

How to calculate the per unit cost.for example if 85,747 Kwh

if one thousand watt motor is ON for one hour, it will cnsume one unit.

And

If 2kw motor is ON for one hour, it will cosume two units .

2kw for 2 hr will cosum 4 unit.

Units = power * time

sir, i want to calculate units for street lights.. inwhich so many lamps are used.. like mercury , metal halide , cfl lamps and led also.. so how can i calculate units for such variable wattage

i want to calculate my electricity consumption for my washer ,

washer is three phase induction motor

Respected Sir,

This site is very useful for me . Sir i want to know that how many watts usually a fan , heater,refrigerator, T.V and a computer consumes????????????

Reply me as soon as possible.

what is d charges for 50 units

Sir if i switch ‘ON’ 40watt energy saver for 1hr, so than what will be the total cost for 1hr. it would be 40watt according to formula or some thing else.

why we multiply 24hrs into kwh????

According to the rate of electricity charge , minimum charge upto 20units is Rs 80 and the cost per units from 21 unit to 250 units is Rs 7.30.How much do 200 units cost?

I have a cooler with 105 w mortor. How many unit in 24 hours ?
