UCAN'S KILOWATT CALCULATOR
This table gives you a good idea of the cost per hour to run typical appliances. We have estimated the average cost of a kilowatt-hour at 17.5¢.
The estimate includes transmission costs, baseline costs, the average tiered rate, etc. Your actual electric cost may be slightly more or less.
Calculate the hourly electric cost of almost anything in two easy steps.
1. Take the wattage listed on the device and divide it by 1000 to get the number of kilowatts that is uses in one hour (one kW = 1000 watts).
2. Multiply that number by 17.5¢ to determine how many cents it costs you to run that item for one hour. Example: To calculate the hourly cost of running a 100-watt bulb for one hour, take 100 watts and divide it by 1000. Then multiply the result by the current market rate of 17.5¢ (that’s 00.175). The result is 1.75¢ per hour.
What to do if wattage isn’t listed ... If no wattage is listed on the device, take the Amps the appliance uses and multiply by the number of volts. The result is the wattage. Most small appliances use 120 volts - large appliances are usually 240.

2 hp pool pump/motor
How much would it cost per day to run a pool with a 2 Hp pump/motor?
Thanks
2 hp pool motor cost per day
Deppending how many amps your pool motor draws. The calculation is amps X hour run motor X Killowatt Rate (depending what tier your on) (Utility bill) = Cost Total
I feel like we are back in a
I feel like we are back in a physics class. I never liked physics but I get the idea here and actually it's not that difficult. I have the opportunity to make a little experiment now. I plan to renew my kitchen appliances with new energy star ones from Kenmore parts. I want to calculate the energy costs for my old appliances now and then recalculate it for the new appliances. The difference will be my savings.
kilowatt calculator
wow this was really insightful. I am unplugging the fridge in my garage. I had no idea that sucker cost me $30 a month to operate! and keep food that probably cost less than that.
