Calculation breakdown
- Credit
- Credit = exported kWh × feed-in tariff rate
Worked example
Exporting 8 kWh a day at a 5c/kWh feed-in rate earns about 40 cents a day, roughly $146 across a year.
Assumptions
- Feed-in tariff rates vary by retailer, state and plan; use your own bill for accuracy.
- Export credit cannot generally reduce a bill below zero.
- Excludes any minimum demand or supply charges.
How this calculator works
Enter the daily kWh you expect to export to the grid and your retailer's feed-in tariff rate to estimate daily, quarterly and annual credit. Feed-in tariffs vary widely between retailers and states, so use your own plan's rate for accuracy.
Frequently asked questions
Where do I find my feed-in tariff rate?
It is listed on your electricity bill or your retailer's plan documents, usually in cents per kWh exported.
Why is my feed-in rate lower than my usage rate?
Retailers generally pay less for exported energy than they charge for imported energy, reflecting wholesale market value.
Does this include the daily supply charge?
No, feed-in credit is separate from and typically cannot exceed your total bill, so very large exports may not fully offset supply charges.
Actual prices, usage, efficiency and savings vary by provider, equipment, location and behaviour.
