    Double check my number's for me

    Can someone double check my number's for me on the operating cost of my pump?

    15amp, 115v. KWH cost at highest rate is 0.08257 (rounded up to 0.9). Running the pump 4 hours a day.

    I'm coming up with a cost of 18.63 at 4 hours x 30 days.....seems low....:-/

    You are doing your math correctly. The actual cost is probably even lower than that, as 15 amps is almost certainly the peak current for the pump, rather than the routine usage current (which will be lower).
