Let's do the math by hand:
- power consumption * usage time = power consumed . So we'll consume 10000 watt hours or 10 kilowatt hours of power every day.
- The electricity cost is cost = power consumed * energy price . ...
- For the annual cost, simply multiply the daily one * the number of days in a year.

How to Calculate Your Electric Bill
- Multiply the device's wattage by the number of hours the appliance is used per day.
- Divide by 1000.
- Multiply by your kWh rate.
How do you calculate electricity cost per kWh?
kWh Explained
To calculate the kWh for a specific appliance, multiply the power rating (watts) of the appliance by the amount of time (hrs) you use the appliance and divide by 1000. This 60-watt lightbulb that we used for 90 hours in a month when we were charged $0.09/kWh cost us approximately 50 cents for the month.
How much does 1 kW hour cost?
A 1kW fire running for one hour uses 1kWh of energy used in kilowatt hours. One kWh of energy costs about 11 to 21 pence. (Look on your bill for the exact rate you are paying.)
How do we calculate efficiency?
The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it's energy production or machine efficiency.
How do you calculate electricity cost per unit?
and we know 1 kWh is equal to 1 Unit.. so if there is 1000 watts appliance used electricity for 10 hours then it means 10 units of electricity used.. if 1 unit is of 5 rupees then we can find out the monthly cost as.. 1000 Watts*10 Hrs*30 Days= 300000 watts/hour. Where is 1 unit = 1 kWh. Cost of per unit is 5.
How do you calculate electric bill in Excel?
Enter formula for Units Consumed= D5 – C5 in cell with cell reference E5. Enter formula for Electricity Charges =IF(E5>200, E5*15,IF(E5>100, 1000+(E5-100)*12, E5*10)) in cell with cell reference F5. Enter formula for Surcharge = IF(F5>5000, F5*5%,IF(F5>1000, F5*3%, 0)) in cell with cell reference G5.
What is the cost of 1 kWh of electricity in India?
During fiscal year 2019, the average cost of state electricity supplied in India was 5.43 Indian rupees per kilowatt hour.
Who has the cheapest electricity per kWh?
Thanks to its great crude oil and natural gas production output and being a net exporter of energy, Qatar enjoys some of the cheapest electricity prices in the world. Here, the average household pays only 0.03 U.S. dollars per kilowatt hour.
What is standing charge for electricity?
With energy, the standing charge is the cost of having a gas and electricity supply – then you pay usage charges on top. Therefore the standing charge is the fee you pay to your energy supplier simply because it gives you access to energy.
How much does 1000 watts cost per hour?
Appliance Electricity Usage
| Appliance | Typical Consumption Per Hour | Cost Per Hour (at 10 cents per kilowatt-hour) |
|---|---|---|
| Hair dryer | 1,200 watts | 12 cents |
| Electric range burner | 1,000 watts | 10 cents |
| Refrigerator | 1,000 watts | 10 cents |
| Desktop computer and monitor | 400 watts | 4 cents |
How do we calculate time?
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
What is the formula for calculating energy efficiency?
Energy efficiency is calculated by dividing the energy obtained (useful energy or energy output) by the initial energy (energy input). For example, a refrigerator has an energy efficiency of 20 to 50%, an incandescent bulb about 5%, a LED lamp over 30%, and a wind turbine 59% at most.
How do you calculate work?
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
