To calculate power consumption of any appliance, you have to multiply it’s wattage by the number of hours it is being used (operational hours). For example, a 1000 watt electric iron running for one hour will consume (1000 watt X 1 hour) 1000 watt hour or 1 kilowatt hour (kWh) of electricity.
How is electrical consumption calculated?
To calculate energy consumption costs, simply multiply the unit’s wattage by the number of hours you use it to find the number of watt-hours consumed each day. For example, let’s say you use a 125 watt television for three hours per day.
How do you calculate electricity cost per kWh?
The kilowatt-hour rate is the price of power supplied by your electric provider. To calculate your kilowatt-hour rate, divide your total power bill, minus any taxes, by your total power consumption.
How do you calculate kWh usage?
Calculate your energy consumption
To work this out, get your previous total (in this case, 750) and divide it by 1,000 (because 1 kilowatt equals 1,000 watts). So, 750 watt-hours per day/1000 = 0.75 kWh (per day).
How do I calculate my electricity meter reading?
- UNIT CONSUMED = CURRENT MONTH UNIT( KWH) PREVUOUS MONTH UNIT(KWH)
- ENERGY CHARGE (EC)= UNIT CONSUMED x UNIT RATE.
- FIXED CHARGE (FC)= SANCTION LOAD x FIXED CHARGE RATE.
- ELECTRICITY DUTY (ED)= (ENERGY CHARGE + FIXED CHAREG)x TAX RATE/100.
- TOTAL ELECTRICITY BILL= ENERGY CHARGE+ FIXED CHARGE+ ELECTRICITY DUTY.
How do you calculate bill amount?
Calculate Your Electricity Bill in 1 min by Simple Calculation. Electric Energy Bill Calculator
- Example:
- Total Consumed Units = 720.
- E = P x t ( Wh)
- E = P x t ? 1000 ( kWh)
- Consumed Energy = Energy Used in Watts x Time in Hours.
- E = P x t ( Wh)
- E = P x t ? 1000 (
- Energy Cost = Energy Used in kWh x Time in Hours.
