GROSS MARGIN PER UNIT
How many dollars each sale generates after the cost of producing it — the most direct measure of product-level profit.
What you charge for one unit of the product.
The full cost of producing or acquiring one unit — materials, labor, and allocated overhead. Use COGS divided by units sold for an existing product.

What this tells you
Gross margin per unit tells you how much each individual sale puts in your pocket after the cost of producing or buying the product. This is the dollar version of gross profit margin — useful when thinking about volume, pricing changes, or whether to add a new SKU. Above $10 per unit is healthy for most products; below $2 means you need volume that few businesses can sustain.
When to use it
Calculate gross margin per unit when setting prices, evaluating product mix, or deciding whether to discount. Pair it with break-even volume to understand the real cost of a price cut — a $5 discount on a $20 margin is half the profit you used to keep. Pair it with contribution margin when thinking about marginal economics, since contribution excludes allocated overhead.
What it doesn’t tell you
Gross margin per unit does not account for fixed costs, marketing, sales, or any operating expense beyond cost of goods. A product with a great gross margin per unit can still lose money if the rest of the cost structure is too heavy. Use this for product-level decisions; use net income for business-level decisions.
