(watts of lamp divided-by 1000) times 24 hours times cost of electricity per KWH For example, if your area electricity costs are $0.12 per KWH and you want to know how much it will cost to run a 75 watt lamp (of any type) for 24 hours, the cost would be (75 / 1000) x 24 x 0.12) == $0.216, or 21.6 cents per day.
