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.

## Step 1

Check your electric bill for the kwh cost. It will be listed clearly.

## Step 2

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.

## Step 3

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.

## Step 4

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.

## Step 5

Multiply the result by the kwh price. As an example, if the KWH price is 17.2 cents, the result 9,735.2 cents.

## Step 6

Divide the result by 100. Here, the result is 97.352. This is the dollar figure.

## Step 7

Round off to the nearest cent. Your final total in this example is $97.35.
