Practical Example

Let’s say you want to calculate your monthly electricity cost with the following values:

  • Energy Consumption: 500 kWh
  • Rate: $0.12 per kWh
  • Fixed Charge: $10
  • Tax: 5%

Calculation Breakdown:

  • Base Cost:
    500 kWh × $0.12 = $60
    $60 + $10 (fixed charge) = $70
  • Tax:
    5% of $70 = $3.50
  • Total Cost:
    $70 + $3.50 = $73.50

Result Displayed by the Tool:

  • Cost Before Tax: $70.00
  • Tax Amount: $3.50
  • Total Cost: $73.50
