# How does your recommendation and savings estimate tool work?

The recommendation and savings estimate tool takes the information you provide from your electricity bill, home set-up, and building information to calculate the right size system for your needs. 

**What it looks at:** 

- **Electricity Rates/Tariff**: Rate/Tariff you are currently on from the electricity bill you upload 

- **Enlectricity retailer**: if you don’t have your electricity bill available, the system will use the popular plans available from the retailer you enter 

- **Electricity Use**: Taken from your electricity bill and Market Settlement and Transfer System (MSATS), this provides the average daily use of your home.  

- **Home set-up:** The big energy using items in your home: EVs and Pools 

- **Roof information:** Shading (e.g. tree overhang), roof and eaves height, roof material (e.g. tiled), roof shape, roof pitch, roof north facing size – taken from publicly available information
