If you listened to Chuck's SCA lecture either live or in podcast form - Here are the numbers breakdown we promised. As you can see for a cafe we're gunning for a total gross margin of 60%, with an itemized sales mix and individual item margin contributions on the right. It's important to note that this is for coffee shop type businesses and not restaurant / food based cafes.

Also if you want to join the movement to create more sustainable careers: join Chuck's list below. Enjoy!
