[SOLVED]Help me with calculating the cost of running my PC

If my electric company charges "10 cents per kilowatt hour". Then if my PC consistently draws 500 watts from the wall, this is called half-a-kilowatt/hour, correct?

1. Does it cost 5 cents per hour in electricity to run my PC?

2. Running my PC for 24 hours each day will equate to \$1.2/day or \$36/month?

There is no need to calculate. Buy a Kill-A-Watt gadget, program it with cost-per-kilowatt, leave it plugged in say for 1 week, then BAM! u will find out EXACTLY what it cost u to have that think running for a whole week, UNLESS you are in an area where utilities are cheaper during off-peak, then oooops, monkey wrench.

1. Your PC does NOT consistently draw 500 watts. At idle, like when you are asleep and it is simply 'on', maybe 80-90 watts. In actual hardcore use, maybe 300 watts. (Of course, we do not know your specs)
2. Calculate electricity cost here: https://www.rapidtables.com/calc/electric/electricity-calculator.html
For instance...
Idling for 16 hours a day (on 24 hours, you using it 8 hours, 16 hours idling), a PC that idles at 80 watts will cost \$46.75 per year. \$3.89/month.
Hard core use at 300 watts for 8 hours = \$87.66 per year. \$7.30/month.

Your actual total cost would be \$11.29/month, or \$134.41/year.
