Quick answer
Electricity rates vary by state, distribution area, retailer and tariff structure, so there is no single Australian cents-per-kWh figure that fits every household.
What matters most
- Use your own bill in calculators.
- AER Default Market Offer applies as a reference/safety-net in NSW, South Australia and South East Queensland.
- Victoria and Western Australia use different regulatory arrangements.
Use your own tariff where possible
Australian electricity prices vary by plan and network. A national average can be useful for a rough example, but a decision-quality calculation should use the usage charges shown on your current bill.
How to calculate it with SunnyWatly
Use the relevant calculator with your own bill, quote or vehicle information. Defaults are examples only and can become stale as tariffs, rebates and hardware change.
Do not rely on a headline figure alone. Ask what assumptions sit behind the estimate and whether they match your property, tariff and usage pattern.
What can change the result
- Electricity usage and time of day.
- Retail import and feed-in tariffs.
- Roof, shading, inverter or charger constraints.
- Hardware efficiency and usable capacity.
- Network limits and future tariff changes.
