Per hour.
Your electric company charges by the kwh or per 1000 watts. To figure how much you stereo is costing you the formula would be: 732 watts = .732 x "the kwh rate". So if the rate was say 20 cents per hour, you would be paying 14.64 cents per hour, not so much, BUT if you leave it on 24/7, you will be adding $105 a month to your bill. You will probably get a Xmas card from them.
