power companies charge by the kWh. figure up your total watts (for the computer fans, take the voltage you are running them at and divide it my their amperage)
and multiply by time

flowering:

lights:
.1kW x 12h x 30 days= 36kWh x power rate = monthly cost

fans:
9v / 1.2a = .008kW (give or take) x 24h x 30 days = 5.76kWh x power rate = monthly cost

veg:

lights:
.032kW x 2 lights x 24h x 30 days = 46.08kWh x power rate = monthly cost

fans:
9v / 1.2a = .008kW (give or take) x 24h x 30 days = 5.76kWh x power rate = monthly cost


i hope that helps!


NOTE: i made an error at first, the decimal place should be right now. sorry for the crazy numbers, i was awake late studying to for a test.
