Hi @pinkfrog1 ,
Thank you for your feedback.
Supply charges are included in the 'cost so far' calculation. The details of what amounts to the cost so far, please see https://community.agl.com.au/t5/AGL-App-and-Online-Services/How-is-my-projected-energy-bill-calculated/ta-p/1242.
We acknowledge that it's not the most intuitive so we are working on an initiative to help our customers understand what costs are included in the 'cost so far'.
