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.
Once you have your data, use the following formula to compute the cost of use:
- Multiply the wattage of the gadget by the number of hours it is used per day.
- Add your kWh rate to the total.
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, multiply by 1000 (7501000 =.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 can you figure out how much electricity costs per kWh?
The price of power delivered by your electric provider is expressed in kilowatt-hours. Divide your total power bill, minus any taxes, by your total power consumption to get your kilowatt-hour rate.
Once you have that amount, you may use the formula below to figure out how much you pay for electricity.
Your power cost is $0.12 per kWh if your total monthly power bill is $327, your electricity taxes are $27, and your monthly power use is 2,500 kWh.
How can you figure out how much electricity costs?
Let’s say our monthly utility cost is as follows:
- electricity usage: You use 1000 watts of electricity.
- The cost of energy is 0.28 cents per kilowatt-hour.
- The daily usage time is 10 hours.
If we know that, our electric bill calculator will inform us that we’ll use 10 kWh per day, for a total of $1022.70 per year.
Let’s have a look at the math by hand:
- The power consumed is the total of the power consumption and the time spent using it. As a result, we’ll need 10000 watt hours (or 10 kilowatt hours) of electricity every day.
- The cost of electricity is calculated as follows: cost = power consumed * energy price. It’s simple: 10 kWh per day multiplied by 0.28/kWh equals 2.8 kWh per day.
- Simply multiply the daily cost by the number of days in a year to get the annual cost. 2.8 per day multiplied by 365.25 days equals 1022.70. As predicted by the electricity cost calculator (surprised?).
Now that you know how much electricity costs, you might be interested in using the price per amount and discount calculators to save money, or finding out how much charging your car adds to your account.
How can I figure out how much electricity I use each month?
Being a responsible adult includes budgeting for your monthly bills. Even if you have enough money to pay your power bill without anxiety, it’s still a good idea to keep track of your energy usage and double-check your bills.
To figure out how much power you use, you’ll need to track down the usage of each appliance and equipment in your home, especially those that are used frequently. We’d all live in smart houses with an app that broke down our usage if life were a bit easier! Unfortunately, this isn’t the case right now. The good news is that calculating your monthly bill and determining how much electricity each appliance uses is not as complex as it may appear.
How do you calculate electricity usage?
The first step in calculating electricity consumption is to determine how many watts each of your appliances and devices use every day. You can do so by multiplying the wattage of the appliance by the number of hours it is utilized per day (see equation below).
- watt-hours = appliance or gadget wattage (watts) x hours used (per day) (per day)
You must divide this figure by 1,000 to get kilowatt-hours because this provides you watt-hours (a kilowatt equals 1,000 watts). This will provide you the appliance’s or device’s daily kWh usage.
After that, multiply the total by 30 to get a monthly estimate (the average number of days in one month).
monthly electric usage (kWh/month) = daily usage (kWh) x 30
How do you calculate the cost of running an electrical item?
An electricity usage monitor, which can be purchased for roughly $25 to $50 at a hardware store, is a fantastic way to get the most precise estimate for the cost of running a certain electrical device. Because these monitors are designed to detect the power consumption of devices that operate on 120 volts, you may find that your monitor is unable to assess the power consumption of your larger appliances.
You simply plug an electrical usage monitor into an outlet before plugging the item into it. The monitor will display a reading of how many watts the gadget is utilizing at the moment it is turned on. You can also check the display after an hour, a day, or a week to see how much energy the device used during that time.
Finding a monitor that allows you to enter your utility’s electric rate is a smart idea because it will give you a pretty accurate estimate of how much the device is costing you each day.
Calculate electricity cost for appliances
To figure out how much power each appliance costs, simply multiply the monthly usage in kWh by the electric rate provided by your utility company and/or electric plan.
- Monthly usage (kWh) multiplied by the monthly electric rate ($/kWh) is a monthly cost estimate.
If you’re on a variable tariff, figuring this cost may be more difficult, which is why an electrical usage monitor that provides an estimate may be useful.
How do you calculate cost per kWh?
To calculate cost per kWh, you must first determine how much you pay per kWh, generally known as your electric rate provided by your electricity provider. (This can usually be found on your most recent bill.) The wattage of the gadget or appliance must then be determined, which can typically be found somewhere on the product (or with a quick Google search!).
After that, apply the following formula:
- (wattage of gadget or appliance x number of hours utilized per day) 1,000 times the kWh electric rate
How much money is a kWh?
This fluctuates significantly depending on where you live and what tariff you have. In the United States, the average is 13.19 cents. Examining your most recent bill is the best approach to find out. Here’s a breakdown of electricity rates by state.
How much is an average electricity bill?
In 2019, the average annual power use for a resident was 10,649 kWh, according to the Energy Information Administration (EIA). That works out to about 877 kWh per month on average. On average, $117.65 per month is spent on this service.
Why is my electric bill so high?
If your electric bill is unusually high, it could be due to a variety of factors. Many of us spend more time at home than we would if we went to work every day. As a result, we use more power. Electric bills are also greater in the summer when we need to keep our homes cool by running the air conditioner all day, or in the winter when we use heat, depending on where you live.
Other factors that contribute to high electric expenses include:
- Appliances and devices that are left on standby consume small quantities of electricity even when they are turned off, wasting electricity and increasing expenses.
- Using large appliances more frequently than necessaryDishwashers, washers, and dryers use a lot of electricity to run, so using them every day may add up quickly.
- Appliances that are out of date
- Older appliances simply consume more energy than newer versions, which are designed to save energy. That doesn’t mean you should throw out your appliances if they’re still working, but if they’re nearing the end of their useful life, consider replacing them with more energy-efficient alternatives.
How can I reduce my electric bill?
You may easily make a variety of modifications to lower your electricity usage and, as a result, your electric bill, if you keep these tips in mind.
At the outlet, turn off all appliances and devices. You may acquire smart outlets that can be turned off from your phone or utilize timer plugs that automatically turn electronics off at specified times.
Larger appliances should only be used when absolutely essential. When feasible, only run the dishwasher when it is entirely full, and use the shortest cycle and lowest temperature possible. Similarly, limit your use of washers and dryers to one laundry day each week, filling each appliance to capacity, and using the lowest heat setting possible.
Create a draught-free environment in your house. To keep heat in your home and chilly air out, get a draught-proofing kit or draught excluders. Pay special attention to any outside doors and windows.
Only heat and cool the rooms that you use. Heating and cooling are the most expensive aspects of power, thus minimizing the amount of space your system needs to heat and cool will automatically save costs. Another thing you can do to save money on heating and cooling is to set your thermostat a few degrees higher or lower than usual. Maintain a temperature in your home that allows you to wear a t-shirt in the summer and a sweater in the winter.
Replace all of your lightbulbs with LEDs. Although they are an initial investment, they will pay for themselves over time by dramatically lowering your lighting expenditures.
In the summer, consider drying your clothing outside. Although a clothes dryer is a fantastic innovation that few of us could live without, using it in weather where your clothing may dry in 30 minutes is counter-intuitive. Simply hang them on the line to save money on your dryer bills.
Calculating your power bill is a fantastic way to make sure you stay on budget for the month and see if you need to make any changes to your energy use habits. Switch to Inspire Clean Energy if you want to switch to a more environmentally friendly energy source.

In the Philippines, how is an electrical bill calculated?
How to figure out how much electricity is used in the Philippines. For the current month’s power consumption, subtract your current reading from last month’s reading (whatever sort of meter you used). Multiply it by current per-kWh electricity prices to get your electricity costs.
How do I figure out how much electricity I’ll use at home?
The number of units of power used by your family in a billing period, which is normally one month, is used to calculate your electricity usage. The number of units utilized at any given time is displayed on your power meter outside your home. Typically, the reading represents the total usage since the installation date.
Meter reading is done in Pakistan by a variety of meter readers who are assigned to different parts of cities. The date of the meter reading/checking is usually printed at the top of the electric bill. The current billing month, issue date, and due date are all mentioned on the top of the page.
Please keep in mind that the computerized version of the bill, also known as the WAPDA online bill, is usually available a few days before the printed form is delivered to households.
To ensure that there are no discrepancies, it is recommended that the electricity use reported on the statement be verified by checking the meter yourself around the typical meter reading date for your residence. Notify your subdivision officer (SDO) at the local electric supply office if you observe a considerable disparity between the actual and reported values. Your SDO’s contact information can also be found on your electric bill.
Additionally, if you detect an increase in your unit use or electricity bill, compare it to the same months the prior year. This information can be seen in your electricity bill’s billing history columns.
A meter reader subtracts the current month’s reading from the previous month’s recorded reading to compute a household’s monthly unit consumption. All WAPDA utility invoices printed in Pakistan include the current and prior month’s units.
The number of units utilized is the key factor of the electricity bill (in Pakistan). The Price Build-Up is calculated using the following charges and rates:
- Charges That Vary (Slabs)
- 201300 units at Rs. 10.20 each;
- 301700 units at Rs. 15.45 each;
- Above 700 units, the price per unit is Rs. 17.33.
- rs. 0.00 per unit, 201300
- Rs. 0.55 per unit, 301700
- Rs. 0.67 per unit above 700
- Rent of Rs. 15.00 per meter
- Electricity Duty (Domestic & Industrial: 1.5 percent each, Commercial: 2 percent, Bulk: 2 percent, and Agricultural: 1 percent of variable charges)
- Sales Taxes in General (roughly 17 percent of the gross amount)
- Fee for a television license (in action since the start of 2010, all TV users are expected to pay Rs. 35 & 60 per Television set if they are domestic and commercial respectively.)
- Charges at the Bank (minimum of Rs. 8.00)
Important to note:
- The numbers 1 and 2 refer to the number of units utilized.
- Domestic, commercial, industrial, and other users are classified using numbers 4 and 5. Applied to Gross Amount, which is determined by the number of units produced.
What method do you use to calculate meter readings?
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:
Analogue (dial) meter
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.
- meter reading at the moment Last month’s bill meter reading = Total kWh used since the last reading
- Total energy charge = Total kWh utilized since the last reading x Charge per kWh
- Final bill = total energy charge + fixed monthly fees
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.
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 can you figure out how much kWh you use in a day?
Because one kilowatt equals 1,000 watts, calculating the kWh per day used by your refrigerator is as simple as dividing the watt-hours per day (7,200) by 1,000, yielding a total of 7.2 kWh per day.
What is Meralco’s method for calculating kWh?
To manually estimate the electricity usage of a specific equipment, follow these steps:
- Get the wattage of your device. This information can be found on the device’s bottom or back, or in the owner’s handbook. You may also look up the device’s technical specifications online.
- Calculate how many watts the device uses on a daily basis. Calculate the wattage by multiplying it by the average number of hours the device is used each day. Let’s imagine you spend 10 hours a day using a 100-watt electric fan. When you multiply 100 watts by ten hours, you get 1,000 watt-hours, which is how much energy an electric fan uses in a day.
- To convert watt-hours to kilowatts, use the formula below. To convert watt-hours to kilowatts, multiply the device’s watt-hours by 1,000. This is the unit of measurement used on Meralco bills. In the previous example, 1,000 watt-hours divided by 1,000 equals 1 kWh each day.
- Calculate the device’s monthly power usage. To figure out how much your device consumes every month, multiply its daily kWh by 30 days. The monthly consumption of an electric fan that consumes 1 kWh per day is 30 kWh.
Make a list of your equipment and devices’ monthly electricity usage and rank them from highest to lowest. This will show you which ones use the most energy and should be used less frequently and unplugged more frequently.
