Why EcoGuide?
Every running cost on this site uses your state's current regulated reference tariff, the same benchmark the regulators publish, and we refresh the lot each July when the new financial year's rates land. Plenty of calculator sites quietly run on a national average from years ago. This one tells you the rate it used and where that rate came from.
Your location and your My Home tally live in your browser, and that's the only place. There are no accounts and we never see your details. Each page gives you the number in seconds, shows its working, and mentions the one or two tricks that cut the cost most. Then you can get back to your day.
