How to Calculate Electricity Cost

Your electricity bill is based on energy consumed (kWh) multiplied by the utility rate, plus fixed charges.

Formula

Monthly Bill = (kWh * Rate per kWh) + Fixed Charge

Average US Rates

  • National average: ~$0.15/kWh
  • Cheapest states: $0.08-0.10/kWh (Louisiana, Oklahoma)
  • Most expensive: $0.25-0.35/kWh (Hawaii, Connecticut)

    • Example Calculation

    A home using 900 kWh/month at $0.15/kWh with a $12 monthly fixed charge.

    1. 01Usage charge: 900 * $0.15 = $135.00
    2. 02Monthly bill: $135.00 + $12.00 = $147.00
    3. 03Annual cost: $147.00 * 12 = $1,764
    4. 04Daily cost: $147.00 / 30 = $4.90
