Contribution margin calculator

Three margins instead of one, because the goods, the order and the customer are three different questions.

Why they all look the same

Each one is a slice of the same P&L.

Most calculators on the web are standalone: they answer one question with one formula and the answer sits nowhere. These 32 share a structure, because the questions do. Break-even is a question about contribution margin. Contribution margin is a question about what the goods, the parcel and the gateway took. Advertising efficiency is a question about the margin the ads have to come out of.

So every result here carries the line number it is on a nouz statement. CM2 is line 25 in this calculator, in the glossary, in the product and on a customer’s own P&L. If a figure has no line number it is because it is a ratio rather than a line, and the page says which two lines made it.

They are estimates, and every page says so where it matters. A calculator works from flat rates you type once. The product prices every single order from the cost rules that were in force on that order’s own date, which is a different and much slower kind of arithmetic.

What the numbers mean

14Net revenue
What you sold, after returns and with VAT out. Every share on every calculator is measured against this.
19CM1
Net revenue minus the goods. Does the product pay?
25CM2
CM1 minus shipping, packing and payment fees. Does the order pay?
29CM3
CM2 minus advertising. Does the customer pay?
33EBITDA
CM3 minus rent, salaries and software. What is actually left.
20 of the 32 work out line 25, CM2: what is left after the goods, shipping and payment fees, before any advertising.
