Appliance Use Chart
Below is a table of appliances with approximate wattage and time of use for a typical household. Your usage is probably much different in certain areas. To use the chart, or use your own numbers, multiply the wattage by the estimated time of use expressed in hours, divided by 1000. Multiply this result by the appropriate rate per kWh.
For example – 1500 watt microwave - used 30 minutes per day (30min./60 = .5 hours)
1500 watts multiplied by .5 hours divided by 1000 equals .75 kWh
.75 kWh multiplied by 9.45 cents per kWh (.0945) equals a cost of 7.1 cents per day or $2.20 per month.
