Monthly Electricity Bill vs Monthly Electricity Use
公式
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
计算示例
A home using 900 kWh/month at $0.15/kWh with a $12 monthly fixed charge.
- 01Usage charge: 900 * $0.15 = $135.00
- 02Monthly bill: $135.00 + $12.00 = $147.00
- 03Annual cost: $147.00 * 12 = $1,764
- 04Daily cost: $147.00 / 30 = $4.90
