How to Calculate True kWh Cost

Your true electricity cost includes more than just the generation charge.

Formula

All-In Rate = Total Bill / kWh Used

Variable Rate = (Total Bill - Fixed Charges) / kWh Used

Bill Components

  • Generation charge: 50-60% of bill
  • Delivery/distribution: 20-30%
  • Taxes and fees: 10-20%
  • Fixed monthly charges: flat fee regardless of usage

    • Example Calculation

    A $150 electric bill for 900 kWh with $15 in fixed charges.

    1. 01All-in rate: $150 / 900 = $0.1667/kWh
    2. 02Variable rate: ($150 - $15) / 900 = $0.1500/kWh
    3. 03Fixed charge share: $15 / $150 = 10%
    4. 04Annual cost: $150 * 12 = $1,800
