What is gross margin?

Gross profit expressed as a percentage of revenue.

In plain English

Gross margin turns gross profit into a percentage, which makes it comparable across products, services and time. A service at seventy per cent gross margin and one at twenty are different businesses even inside the same company.

For marketing, this is one of the two or three numbers that matter most. It determines how much of every sale is available to pay for acquiring the sale.

What to know

A percentage, not an amount
Gross profit divided by revenue. Comparable between lines of work and across periods.
It caps acquisition spend
If gross margin is thirty per cent, then thirty pence in every pound is all there is to cover marketing, overheads and profit.
Higher margin buys options
High-margin businesses can afford paid channels, longer payback and testing. Low-margin businesses must rely on cheaper acquisition.
Track it per line
Averages conceal. Margin by service or product is what tells you which work to pursue.

Why it matters

Gross margin explains why a channel that works for one business is ruinous for another. Two competitors can face identical advertising costs and only one can afford them. Before asking whether a channel works, work out what your margin permits.

Common mistakes

×Comparing your advertising costs to businesses with completely different margins.
×Growing the lowest-margin line because it converts most easily.
×Discounting without recalculating what margin remains.
×Never separating margin by product or service.

FAQs

How does gross margin affect my marketing budget?

It sets the ceiling. Your acquisition cost has to sit comfortably inside gross margin, with overheads and profit still covered.

What is a healthy gross margin?

Sector dependent. Service businesses are typically far higher than product resale. Compare within your own industry.
