The Formula
Gross Margin = (Revenue minus Cost of Goods Sold) / Revenue x 100If you earn 1,000,000 dollars and it costs 200,000 dollars to deliver the product, your gross margin is 80 percent. That 80 percent is what remains to cover sales, marketing, R&D, and profit. Gross profit is the same calculation expressed in dollars rather than a percentage: Revenue minus COGS.
What Belongs in COGS
The number is only as honest as the costs you put in it. For a SaaS business, Cost of Goods Sold is the direct cost of delivering the service:
| In COGS | Not in COGS |
|---|---|
| Cloud hosting and infrastructure | Sales and marketing |
| Customer support and delivery-side success | R&D and engineering for new features |
| Payment processing fees | General and administrative overhead |
| Embedded third-party software | Office, finance, legal |
Why Gross Margin Decides Whether You Scale
Gross margin is the ceiling on every other unit economic. A high-margin business keeps most of each new revenue dollar to fund growth; a low-margin business has to run much harder to net the same result. It directly shapes how much you can afford to spend acquiring customers, which is why it sits upstream of the LTV to CAC ratio and the Rule of 40. Two companies with identical revenue and very different gross margins are not the same business.Track It by Segment, Not Just Blended
A single company-wide gross margin can hide the story. Usage-heavy customers, services-heavy contracts, and different product lines carry different costs to serve. Track gross margin by product and by customer segment, and the blended number stops masking the accounts that quietly cost more to serve than they return. That segment view is also what connects gross margin back to recurring revenue quality and retention.
Frequently Asked Questions
What is the gross margin formula?
Gross Margin equals (Revenue minus Cost of Goods Sold) divided by Revenue, times 100. If you earn 1,000,000 dollars in revenue and it costs 200,000 dollars to deliver, gross margin is 80 percent. It measures how much of each revenue dollar is left after the direct cost of serving customers.
What counts as COGS for SaaS?
The direct costs of delivering the software: cloud hosting and infrastructure, customer support, customer success tied to delivery, payment processing, and third-party software embedded in the product. It does not include sales, marketing, R&D, or general overhead, which sit below the gross margin line.
What is a good SaaS gross margin?
Healthy software businesses generally run high gross margins because software costs little to replicate. The exact target varies by model, and services-heavy or usage-heavy businesses run lower. The more useful exercise is tracking your own gross margin trend over time and by product line, not chasing a single benchmark.
