How To Calculate Electricity Bill With Meter Reading?

You can figure how much your electricity bill should be by conducting your own reading. One of three types of meters will be installed in your home:

Let’s look at how to get the reading from each type of meter before we show you how to calculate your energy usage.

Your electricity is measured in kilowatt-hours by your meter (kWh). One unit equals one kilowatt-hour. Your statement will usually include a cost per unit, which will come in helpful later when we break down the equation for you.

You’ll normally observe five separate dials while dealing with a dial meter. Use the number that was recently passed if the dial is between two numbers. Only read a number if the dial to its right has passed zero.

You’re undoubtedly curious as to what these statistics imply. They are, after all, symbols for the quantity of energy you consume. The more energy you use, the faster your dial will turn, raising the number on the dial. Consider it like the number of miles on your car’s dashboard. The more miles you travel, the more miles will appear on your dashboard. When it comes to reading your meter, the same principle applies.

Digital and smart meters are far more user-friendly and straightforward. You simply need to take note of the first five figures displayed on a digital meter. If, after the first five numbers on your meter, you observe a group of numbers that starts with 0.1, ignore them.

You can compute how much electricity you’ve used since your last electricity payment after you get your meter reading. To do so, locate your most recent electric statement and look at the reported reading. You’ll then deduct your current reading from the previous month’s reading. The total quantity of kWh you’ve used since your last meter reading is the outcome.

The reading on your meter will never be reset to zero. The number on your meter shows the number of kilowatt hours consumed since the meter was installed. As a result, this number will continue to rise, making it critical to compare your meter readings every month.

Energy companies may bill you based on an estimate created from your home’s historical use, which means you may be charged a higher bill simply because individuals who previously lived in your home utilized a lot of energy.

You’ll also need to know how much your utility company costs per kilowatt hour and if your account includes any fixed fees to compute your bill. You’ll be ready to go after you have that information plus the total quantity of kWh utilized since your last meter reading.

You’ll then multiply this figure by the kWh rate your electricity company charges, as well as any set costs.

  • Total kWh used since the last measurement = Current meter reading meter reading indicated on last month’s bill

The equation above will assist you in keeping track of your energy usage. It’s a simple activity that, if completed, can help you save money on a monthly basis. If you care about the environment, you shouldn’t have to pay a hefty energy bill. Calculating it yourself will put an end to your exorbitant bill.

How is the reading on a power meter calculated?

We take readings of kwh and kw from the meter, then unit from the previous month’s unit to determine the unit assessed or spent. We compute using the formula below. How do I figure out how much power I’ll have to pay based on my meter reading?

How can I read my house meter and figure out how much electricity I use?

Electric meters are classified by their display technique (analog or digital), metering point (main and local distribution, grid, and secondary transmission), and how they are used in conjunction with payment (prepayment meters). They are read in a variety of ways, therefore the first step in reading your own is to figure out which type it is. The digital electric meter is the easiest to read of the three types, while dial-based meters need the greatest effort. Using the step-by-step instructions below, learn how to take readings from various types of electric meters. Many electrical suppliers will not make revisions to the number on the meter, so you’ll have to keep track of the updates when you read your meter over time.


A basic electric meter is a glass and metal round box that is normally mounted on the outside of your home. The meter is housed inside a glass container with four or five dials. Each dial is numbered 09 and records the amount of electricity utilized in kilowatts. To read the dials each month, you’ll need to do the following:

  • From left to right, write down the numbers you see. Except when the ticker is between 0 and 9, record the lowest value if the pointer on the dial is between two digits. In that scenario, always make a note of 9.
  • Subtract the amount from the last time you checked the meter. This is the amount of kilowatt-hours you’ve consumed.
  • To figure out how much you’ll have to pay for your bill, multiply the amount of kilowatt-hours you computed by your energy company’s rate.

How can I convert my kWh data from my electric meter?

The number 4 on dial B should be read as 3 because the pointer on dial A has not yet reached zero. Subtract the previous month’s reading from the current reading on your most recent bill to get the number of kilowatt-hours you used throughout the month. This will give you the number of kilowatt-hours you utilized during that time period.

What is the formula for calculating an electrical unit?

A unit is measured in kWH, or Kilowatt Hour, as seen on power bills. This is the amount of power or energy that has been consumed. You expend 1 unit or 1 Kilowatt-Hour (kWh) of electricity if you use 1000 Watts or 1 Kilowatt of power for 1 hour. As a result, the reading on the electricity meter reflects the real amount of electricity consumed. Similarly to the odometer on your car, which displays the actual distance traveled, an electricity meter displays the quantity of electricity consumed. So, if a 100-watt bulb is left on for 10 hours, it will use the following amount of energy:

How is the cost of electricity calculated?

3 600 000 joules equals 1 kWh. The kilowatt-hour is an energy consumption measurement that is computed by multiplying power in kilowatts by time in hours. The energy consumption of various appliances can be calculated by multiplying the power rating by the amount of time it was utilized in hours.

How do you figure out how much electricity you’ll need in a month?

You’ll need to employ some modern technologies to acquire a fully precise accounting of your home’s energy consumption. However, with some simple, old-fashioned arithmetic, you might be able to come up with some reasonable estimations.

You’ll need three figures to estimate the amount of electricity used by a specific appliance or electronic device: the wattage of the item, the average number of hours you use it each day, and the price you pay per kilowatt-hour (kWh) of electricity.

Your kWh rate is stated on your power statement, and calculating your average daily usage is simple. Look for a label or metal plate on the back or bottom of an appliance or equipment to find out how much power it consumes. If the wattage is listed, it will be followed by a “W.” If you can’t find a label, look through the appliance’s original documentation or look up its technical specifications online.

Multiply the wattage of the gadget by the number of hours it is used per day.

So, if you watch 150 watts of television for five hours a day, it uses 750 watt-hours per day (150 x 5 = 750). To convert 750 watt-hours to.75 kWh, divide by 1000 (750 1000 =.75). If your electricity costs 12 cents per kWh, your television will cost you 9 cents per day (.75 x.12 =.09). Your monthly electric cost should be approximately $2.70 (.09 x 30 = 2.7).

To do this with all of the appliances, devices, and lights in your home, you’ll need a lot of figure crunching, so if you want an easier solution, go to technology.

How do you figure out how much kWh you use each month?

A watt (W) is a unit of power measurement. The power consumption of light bulbs is measured in watts, to translate watts into more familiar terms. To produce light of equivalent brightness, a 60 W incandescent light bulb consumes seven and a half times the electricity of an 8 W LED light bulb.

Power usage is frequently expressed in kilowatts. Because watts are such small amounts of power, they are abbreviated as (kW). 1,000 watts equals one kilowatt.

The power rating for each of your key appliances and electronics is calculated by the manufacturer and printed on a label on the device. Your microwave, for example, is likely to have a power rating of 600 W to 800 W.

A kilowatt-hour (kWh) is a unit of measurement for the quantity of energy utilized over a specific time period. The quantity of electricity you used in a month is expressed in “kilowatt-hours” on your power bill.

To determine the kWh for a certain appliance, multiply the wattage (watts) by the number of hours (hrs) you use the appliance and divide by 1000.

We spent about 50 cents on this 60-watt lightbulb that we used for 90 hours in a month when we were charged $0.09/kWh.

Add the power usage of each gadget to compute the total power consumption of your house or business.

  • Building meter: You may calculate the difference between reading your electric meter at the beginning and end of the month.

How can you figure out how much electricity costs per kWh?

You’ll need to convert the wattage of the appliance to kilowatts in order to assess your operating costs; this may be done easily by dividing the wattage by 1000. In this case, we’ll divide a 1000W radiator by 1000 to get 1kW.

If we used an 1800W radiator, the result would be 1800/1000 = 1.8kW; if we used a 450W radiator, the result would be 450/1000 = 0.45kW.
