You can find electricity bill calculator if you keep reading this page. This is very interesting to know that which appliance in your home or office consumes most electricity?

On this page you shall understand the ways and formula for an electricity consumption calculator which can help you calculate energy usage in your home.

In this way you can estimate the electricity consumed by each appliance, your overall monthly energy consumption in kilowatt-hours.

This electricity bill calculator can also help you to find potential savings in energy consumption by substituting with energy efficient appliances.

The demand for electrical energy has increased exponentially over the last many years.

To improve the energy efficiency, consumers needs to be more aware of their energy consumption. This has increased the emphasis on the need for accurate and economic methods of energy consumption.

Understanding of energy or electricity bill calculation enables the user to read the meter readings regularly without any confusion.

Now it can be achieved by the use of micro-controller unit that continuously monitors and records the energy consumption readings.

The energy meter hardware is developed to read the consumption of particular equipment so that one can know about it consumption.

This will help to optimum the use of electrical energy and so that the advantages of increased efficiency, effective utilization and amount of monthly bill can be achieved.

Electricity consumption calculator is for indicative purpose only and its calculations may be different to the actual usage and/or charges contained on your final bill.

There can be difference due to:

- The number of people living in your home; or
- The number, age and efficiency of appliances
- The weather – depending on the day or the season, appliances such as Heat Pumps and clothes dryers are used more frequently

## How to Calculate Electric Bill – kwh formula

In order to calculate your electric bill, you’ll need to figure the energy usage of each of the appliances and electronic devices in your home.

The idea is very simple and estimating your electricity usage would be as easy as looking at an itemized grocery receipt.

In this way you are able to see exactly what you spent to run the washer, do the laundry, watch TV and use a month’s worth of hot water.

There are now technological ways, but if you want to get an appliance-by-appliance breakdown right now, you’ll need to do a little math work as per below energy consumption formula.

Electricity providers or power distribution companies charge you in the form of units which are kilo watt hours (kWH) that means if you consume 1000 watts for one hour it becomes one unit. So you can easily calculate the kWH for each appliance using the below mentioned standard power usage in watts.

If 15 W bulb runs for 1000 hours , it consumes energy of 15 × 1000 = 15,000 Wh or 15 kWh.

so formula for electricity bill calculator kwh formula is:

1 unit = Appliance power in Watts Multiply by Hours of operation divided by 1000 = W x Hours / 1000

**Monthly Electricity Unit Calculation example for One Ton Inverter AC:**

Watts= 900

Time of operation per day = 10 hours

Time of operation per month= 10×30 = 300 hours

Units Consumed = 900 x 300 / 1000 = 270 Units

If cost of one kWh is 0.12 dollars the bill for one ton AC is = 270 x 0.12 = 32.40 dollars.
