What's my electricity cost if rate is 13.2 cents per kWh?

I am running 8,333W, 16 hours a day every day.

Electricity rate is 13.2 cents per kWh.

What will be the total cost per day, per month?

Can you please show the calculation?

Thanks

    8,333 W = 8.333 kW

    8.333 kW x 16 hours/day = 133 kW•hours/day or 133 kWh/day

    133 kWh/day x 13.2 ¢/kWh = 1760 ¢/day = $17.60 /day

    $17.60 /day x 31 day/mo = $546/mo

    edit a bit more correctly, the average number of days in a (non-leap) year is 365/12 = 30.42 days

    using that number, answer is $535/mo

    Cost per day = (8,333W)*(1 kW/1,000 W)*(16h)*($0.132/kWh) = $17.599296 = ~ $17.60/day

    January bill = [$(17.599296)]*(31day/Jan) = $545.578176/Jan = $545.58/Jan

    February bill (3 years out ot 4) = [($17.599296)/(day]*[(28 day)/(Feb)] = 492.780288/Feb = $492.78/Feb

    February bill (1 year out of 4) = [$(17.599296/day)]*[(29 day)/(Feb)] = $510.379584/Feb = $510.38/Feb

    Average bill per month of February over a 4 year period = $[3(492.78) + 510.38]/4 = $497.18/Feb

    March bill = [($17.599296/day)*(31 days/March) = $545.578176/Mar = $545.58/Mar

    April bill = [($17.599296/day)*(30 days/April) = $527.97888/April = $527.98/April

    May bill = [$(17.599296/day)*(31 days/May) = $545.578176/May = $545.58/May

    June bill = [$(17.599296/day)*(30 days/June) = ($527.97888/June) = $527.98/June

    July bill = [$(17.599296/day)*(31 days/July) = $545.578176/July = $545.58/July

    August bill = [$(17.599296/day)*(31 days/August) = $545.578176//August = $545.58/August

    September bill = [$(17.599296)]*(30 days/September) = $527.97888/September = $527.98/September

    October bill = [$(17.599296)*(31 days/October) = $545.578176/October = $545.58/October

    November bill = [$(17.599296)*(30 days/November) = $527.97888/November = $527.98/November

    December bill = [$(17.599296)*(31 days/December) = $545.578176/Dec = $545.58/December

    I think the Power Company rounds bill off to nearest penny each month. Therefore monthly charge may not exactly equal the number of days in month times the rounded off daily charge.

    It costs 13.2 cents per kwh.

    8.333 x .16 x .132 x 30 = $527.98 per 30 day month.

    8,333W * 16 hours = 133,328 Wh = 133 kWh

    133 kWh * 13.2 c / kWh = $17.60 per day

    $527 per month
