Who this is for
Coffee shops run some of the best product margins in food service, a latte's ingredients cost a fraction of its price, and some of the thinnest business margins, because the building and the baristas are paid by the hour whether customers arrive or not. The cup-level math seduces; the month-level math decides.
Enter monthly revenue, the true cost of goods including beans, milk, alternative milks, cups, lids, and pastry purchases, and the full operating load of labor, rent, and utilities. The ticket-size notes below explain why the difference between a $5.40 and a $7.10 average ticket is often the entire profit margin.
