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 is the cost of electricity calculated?
You’ll need to find out how much energy each of your appliances and electronic devices use in order to compute your electric bill. Estimating your electricity usage would be as simple as looking at an itemized supermarket ticket in an ideal world. You’d be able to see just how much you spend on the dishwasher, laundry, TV, and a month’s supply of hot water. That technology is growing closer every day, but for now, you’ll have to perform some arithmetic or spend some money to get an appliance-by-appliance analysis.
How can I manually compute my electric bill?
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.
In the Philippines, how do you compute kWh per hour?
If you want to know how to calculate your power bill correctly, here’s a step-by-step guide:
1. Get a copy of your most recent utility bill. On the back of your bill, look for “Pres Rdg.” Get the current reading from your electric meter. Subtract this from your previous bill’s “Pres Rdg.” Your current kilowatt-hour use will be the answer (kWh).
What is the formula for calculating an electric meter?
Always read the dials from right to left, starting with Dial A and ending with Dial E. The dial’s pointer can be used to read the number. The lower number is recorded when the pointer is between two (2) numbers. Simply subtract the prior reading from the current reading to calculate your electric use.
What is Meralco’s per-kWh rate?
THE PHILIPPINES MANILA, Philippines In April 2022, Manila Electric Company (Meralco) tariffs surpassed P10 per kilowatt-hour (kWh).
Meralco increased its rates by P0.5363 to P10.1830 per kWh for the second month in a row. Meralco’s rates last broke through the P10 barrier in June of this year.
The adjustment equates to price hikes for households that consume the following items:
Due to increasing prices from independent power producers (IPPs) and the spot market, Meralco stated the generation charge increased by P0.3987 to P5.8724 per kWh.
The generation fee would have been greater if the Energy Regulatory Commission (ERC) order instructing suppliers to delay sections of their generation costs, totaling P945 million, had not been in place, according to the power distributor.
In addition, Meralco was instructed by the ERC to defer P300 million in generation expenses, lowering the rise by nearly 11 centavos per kWh. Over the next three months, the delayed fees will be billed in three installments.
Due to the scheduled repair of the Quezon Power Plant till March 24, and higher fuel prices of First Gas-Sta. Rita due to limited supply from Malampaya, IPP tariffs increased by P1.4885 per kWh in April. The devaluation of the peso, according to Meralco, also led to higher IPP expenses.
The WESM (Wholesale Electricity Spot Market) tariffs remained high in March due to a lack of supply in the Luzon system.
Meanwhile, due to the postponement of generation expenses, charges from power supply agreements (PSAs) were lowered by P0.1068 per kWh.
WESM supplied 17.4 percent to Meralco’s April bill, while IPPs and PSAs delivered 31 percent and 51.6 percent of Meralco’s energy requirements, respectively.
Meralco anticipates increased generation rates in the coming months due to the dry season’s rising temperatures.
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?
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.
What is the formula for calculating a bill reading meter?
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 much does Meralco 2020 cost in kWh?
Meralco’s average retail electricity pricing in the Philippines in 2020 was 7.96 Philippine pesos per kilowatt hour. This is a 10% drop in the average retail rate from the previous year.
How can I figure out how many kWh I’ve used?
You will multiply 100 watts by one hour to convert watts to kilowatt-hours. Then divide by 1,000 to get the energy consumption in kWh. If a kWh of power costs 13 cents, a 100-watt light bulb will cost 1.3 cents per hour it is turned on.
