Your monthly electric bill is based on consumption, and that consumption is denoted in kilowatt-hours. The kilowatt-hour (kwh), measures how much energy you use and also for how long. That's why the unit has both an electric component as well as a time component. One kwh is consuming power at a 1,000-watt rate for a full hour. Think of 10 living room lamps burning 100 watt bulbs for 60 minutes, for a practical demonstration of the unit. To calculate your bill, check your meter for the amount of your consumption, then use the kwh price point to figure your total bill.
Check your electric bill for the kwh cost. It will be listed clearly.
Read and note your electric meter reading. The meter measures kwh. To verify the electric company's bill or figure your own monthly bill, take a reading the same day of the month that the electric company is scheduled to read your meter. You can find this information on the bill, too.
Read and note your electric meter reading one month later. Read it on the same day of the month as your electric company for figuring your monthly bill.
Subtract the first reading from the second. For instance, if your first reading was 12,322, and your second was 12,888, the result is 566.
Multiply the result by the kwh price. As an example, if the KWH price is 17.2 cents, the result 9,735.2 cents.
Divide the result by 100. Here, the result is 97.352. This is the dollar figure.
Round off to the nearest cent. Your final total in this example is $97.35.
