Meaning
An electrical bill is a report of how much money you owe a power company for the electricity you use.
About Electrical Bills
- The cost of an electrical bill is based on how much energy is transferred to your house by electricity, measured in kilowatt-hours, multiplied by the cost of one kilowatt-hour.
- The electrical bill calls a kilowatt-hour a 'unit'.
- Cost (p) = Energy (kilowatt-hours) x Cost per kilowatt-hour (p)
- The cost per kilowatt-hour may be different at different times of the day. Electricity is usually cheaper at night when less people are using it.
Calculations
Standard energy units 118 at 12.12p each.
- Cost (p) = Energy (kilowatt-hours) x Cost per kilowatt-hour (p)
- Cost (p) = 118 x 12.12
- Cost (p) = 1430.16p
- Cost = £14.30
Standard energy units 700 at 8.15p each.
- Cost (p) = Energy (kilowatt-hours) x Cost per kilowatt-hour (p)
- Cost (p) = 700 x 8.15
- Cost (p) = 5705p
- Cost = £57.05
Standard energy units 106 at 14.04p each.
- Cost (p) = Energy (kilowatt-hours) x Cost per kilowatt-hour (p)
- Cost (p) = 106 x 14.04
- Cost (p) = 1488.24p
- Cost = £14.88
Standard energy units 626 at 9.44p each.
- Cost (p) = Energy (kilowatt-hours) x Cost per kilowatt-hour (p)
- Cost (p) = 626 x 9.44
- Cost (p) = 5909.44p
- Cost = £59.09
