# 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
