Electricity Bill Calculator

Take control of your electricity costs

For most SMEs, energy is one of the biggest overheads. Even households feel the pinch when bills are unpredictable. Our free Electricity Calculator helps you see your likely costs clearly — so you can plan, budget, and check if your supplier’s charges add up.

How it works

Enter a few simple details from your bill or contract:

  • Electricity used (kWh) – your expected or actual consumption.
  • Unit rate (c/kWh) – the price per unit of electricity from your supplier.
  • Number of days – the billing period you’d like to check.
  • Standing charge (c/day, $ per month or $ per quarter) – the fixed fee.

Hit Calculate, and you’ll instantly see:

  • Your electricity cost based on usage.
  • Your standing charges.
  • Your total estimated bill.
