公式

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
  • 计算示例

    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

    常见问题

    What is the average cost per kWh in the US?

    The US average is about $0.15/kWh, but varies widely from $0.08 in Louisiana to $0.35 in Hawaii. Time-of-use rates can range from $0.05 off-peak to $0.40 on-peak.

    Why is my rate different from the posted rate?

    Posted rates usually show only the generation charge. Your actual rate includes delivery, taxes, demand charges, and fixed fees, making it 20-40% higher.

    What are demand charges?

    Demand charges are based on your peak power draw (kW) rather than total energy (kWh). They are common in commercial bills and can represent 30-50% of the total.
