Electricity Bill Formula

Total Bill = (Energy Consumption × Rate per kWh) + Fixed Charges + (Taxes % × Subtotal)
ExampleIf monthly usage = 500 kWh, Rate = $0.12/kWh, Fixed Charges = $20, Taxes = 5%: Usage Cost = 500 × 0.12 = $60 Subtotal = $60 + $20 = $80 Taxes = 5% × 80 = $4 Total Bill = $60 + $20 + $4 = $84

This formula helps calculate a realistic monthly bill based on consumption and utility provider rates.
