Small Business Unit Economics Model - Contribution Margin & Break-Even (Excel)

Every small business rests on the same question: what does one unit really keep? Small businesses look different on the surface, but they all answer the same question underneath. What does one customer, order or unit contribute once you take out the cost of serving it.
