I’m new and still figuring out pricing too. if you are buying your supplies for retail prices, you are not getting supplies as cheap as a bakery would, but then you don’t have the overhead they do. There is a pricing matrix that someone made up and emailed out, and it helps making pricing easier. I’ve charged $65-$75 for a 2 tier bday cake and felt like it was fair to me and they are repeat customers now, so I know they’re happy! I notice that you do a lot with fondant though, so your pricing would be different. I cover my cakes with just buttercream.
