How to Use
  1. Grab your latest electricity bill
  2. Enter your postcode, billing period, and plan type
  3. Copy your total bill amount and energy usage (kWh)

  5. Add any solar exports if you have panels
  6. See what plan is best for your household, and how much you could save
Key Information
  • Australian bills have two main costs: supply charge (daily) and usage charge (per kWh)
  • Plan type affects rates: single rate, time of use, controlled load (off-peak)
  • Solar panel owners can offset usage and earn by exporting power to the grid
  • Switching plans/rates can save hundreds per year—comparison is key!
  • Many bills include pay-on-time or direct debit discounts. Account for all charges.
Pro Tips
  • If you use power in off-peak times, check if 'Time of Use' plans could save more
  • Compare supply AND usage charges—not just tariffs—to see your true costs
  • Ask your retailer for a better offer—they often discount if you ask
  • For solar owners, compare feed-in tariffs and export caps on each plan
Avoid These Mistakes
  • Only comparing usage rates without checking supply charge or discounts
  • Entering before-GST values (always use the total bill amount for clarity)
  • Not updating your comparison when household usage changes (e.g. after buying new appliances)
  • Forgetting to include solar exports or select 'Solar' if you have panels
