How to calculate electricity bill of your home?
Hey guys! Welcome back to our blog! Do you want to know how to calculate electricity bill of your home? So here is the sample electricity bill calculation. Let's have a look,
It’s pretty easy and straight-forward calculation.
• You should know that, 1 KWh (kilo watt-hour) or 1000 Wh (watt-hour) = 1 Unit of electricity consumption (that you see keep increasing on the electricity unit calculator gauge or meter, i don’t know how you see that in other countries but in India it happens exactly that way)
• We have to estimate the total watt-hour consumed by an appliance per month (a month, because that’s the duration after which we get electricity bill.) and then divide it by 1000 to get the total number of units.
• When you get the number of units of that device, you have to multiply those many numbers of units with the price per unit, which is charged by government of your respective country.
For example:
You keep a ceiling fan of 60 watts powered on for; let’s say; 12 hours a day on average (since it’s almost impossible to keep track of exactly how long we keep our fan powered on for, each day and for total 30 days, it is relatively easy to take/guess an approximate; I mean the closest number of hours you believe you happen to keep the fan powered on for each day). This is how usually we will calculate the bill of that fan per month.
60-watt x approximately 12 hours each day x total of 30 days (30 days because we are charged on monthly basis)
60*12*30=21,600 wh
Now we have to divide this by 1000 and we get that,
21,600/1000= 21.6 units
Our fan consumes 21.6 Units of electricity per month.
Now you need to know the cost per unit of electricity at your area/state/country. At my place it’s around 4 rupees per unit up to 100 or something units (I don’t know the exact value, take this as an example only. If you want to know the accurate information on this, you can download this kind of information from the website of the department of electricity board/company of your state or you can go to the Electricity office and you can ask them directly; they will be happy to provide you with the correct information).
Finally, 21.6 units x 4 rupees = 86.4 rupees total.
• Now you have to do the same calculations with all of your appliances/electronic devices separately that you run on AC power at your home and you can get the close-to-accurate electricity bill.
• The key to accurate estimation is to know for exactly how long each of the electrical/electronic device you use per day and calculate for each of them independently and you have to add all of Wh values at the end of month (30th day). And do add the “rent” part of bill into the final bill, that depending on where you live and what plan have you been subscribed to (business/home/rural etc), it is the constant value immatter of usage of electricity, you to pay a certain amount anyways.
• One more interesting thing is, there are many different rates up to a certain quantity of units.
Followings are only for example and don’t represent a valid rate.
• 2 rupees per unit up to 100 units.
. 4 rupees per unit up to 200 units.
. 6 rupees per unit up to 500 units.
. 7 rupees per unit for more than 500 units.
The final number of Units (total Units) consumed by all of your home appliances is the only number you should account for before multiplying by rate per unit and you must know the price for that range and then you need to multiply that cost value to your total number of units consumed by all the devices.
Suppose you added all the Units together and found out you get 715 units for 30 days or something, then you have to multiply that with the price that is in accordance with your electricity provider. From the above example, since 500+ units is charged at a rate of 7 rupees per unit. Then finally, your total electricity bill will be 715 x 7.
