How the calculator works

A home battery saves you money by storing your cheap daytime solar (or off-peak power) and using it through the expensive evening peak, instead of buying that energy back from the grid. The calculator estimates your yearly saving from four things: your power use, whether you have solar, the battery size, and your state's rebates.

What changes your real savings

  • Your evening usage. The more power you use after dark, the more a battery shifts off the grid.
  • Your feed-in tariff. The lower it is, the more you gain by storing solar instead of exporting it.
  • Your rebates. The federal discount plus your state incentive set the after-rebate price, which drives payback.
  • A VPP. Joining a Virtual Power Plant adds income on top of your bill savings.

How accurate is the savings calculator?
It's a quick ballpark based on indicative energy prices, rebate values and usage patterns. Real savings depend on your postcode, retailer, tariff and how you use power. The free rebate check returns figures specific to your home.
What payback period is realistic?
With current rebates, most households land somewhere around 3 to 5 years, faster with high evening usage or a VPP. After that the battery keeps saving for years, well inside its 10-year warranty. The calculator shows a rough payback for the inputs you choose.
Does it include the federal and state rebates?
Yes. The after-rebate price applies an indicative federal Cheaper Home Batteries discount, and separately an indicative state incentive for the state you select. They are shown as two figures, not one combined number, and your exact amounts are confirmed during the free rebate check.
