How do I calculate my Duke Energy bill from the rate per kWh?+
Multiply your monthly kilowatt-hours by the per-kWh rate, then add the fixed customer charge. Using Duke Energy's estimated effective residential rate of 13.47 cents per kWh and its roughly $14 monthly fixed charge, a home using 750 kWh a month works out to about (750 x $0.1347) + $14 = $115.03 a month. The table above shows the same math across usage levels from 250 to 1,500 kWh. This is a representative estimate; your exact rate depends on the tariff, season, and fuel and rider charges on the official schedule linked above.
How do I find my Duke Energy rate on my bill?+
Your electricity bill shows the total kWh consumed and the charges applied. Look for the 'energy charge' or 'supply charge' line item - this is the per-kWh rate times your usage. Delivery charges (transmission and distribution) are listed separately and represent a significant portion of your total rate. The fixed customer charge appears as a flat line item. Your effective combined rate (all charges / total kWh) may differ from the tariff rate due to the fixed charge amortization.
