Agency gross margin: what good looks like and how to improve it

The one margin number that tells you if the work is profitable

Revenue tells you nothing about whether the work itself makes money. Gross margin does. It's revenue minus the direct cost of delivering the work, expressed as a percentage - and it's the cleanest signal of whether your delivery is profitable, before any overhead complicates the picture. If gross margin is dropping, the work is leaking, and no amount of trimming office costs will fix it.

It's also the number agency owners most often guess wrong. The headline rate looks great, the team is busy, the clients are happy - and yet gross margin is below 40% and shrinking. That gap between vibe and number is where most underperforming agencies live.

How to calculate it without fooling yourself

The formula:

Gross margin = (revenue - cost of delivery) ÷ revenue × 100

The honesty is in "cost of delivery" (COD). Include the fully-loaded cost of everyone whose time the work consumed - salaries, contractor fees, software directly used to deliver, pass-through costs. Exclude rent, sales salaries, the founder's strategy time - those are overhead, not delivery.

The trap most agencies fall into is using salary alone instead of fully-loaded cost (which is roughly salary × 1.3-1.5 once you add payroll taxes, benefits and downtime), and ignoring the time the founder or senior team spent in delivery. Both habits flatter gross margin by 10-15 points and make pricing decisions worse downstream.

What a healthy gross margin looks like

There's no universal number, but useful guideposts:

• Healthy services agencies: north of 50%, often 55-65%.
• Project shops with heavy contractor or media costs: lower (sometimes 30-40%) - but the ratio of revenue to internal cost should still be strong.
• Productized retainers: typically the highest gross margin in the business because scope and delivery are tightly controlled.

The trend matters more than the headline. A dropping gross margin almost always means scope creep, underpriced retainers, or work taking longer than scoped. A rising one usually means the team is getting more efficient on repeatable work - the productizing dividend.

The levers that pull it up

Three reliable ones:

1. Tighter scope. Most margin leaks aren't pricing problems, they're scope problems. Write the boundary down (see the SOW template) and enforce it with change orders instead of freebies.
2. Better pricing. Value-based pricing and productized packages decouple your fee from hours, which is how margin grows even when the work doesn't take less time.
3. Real time data. You can't manage what you can't see. Accurate time tracking turns gross margin from a quarterly surprise into a weekly metric (see the time tracking guide).

The lever that's almost never the answer: cutting overhead. That moves net margin, not gross. Gross margin is fixed at the point of delivery.

How to act on it

Calculate gross margin per client and per project, not just at the business level. Aggregate numbers hide the truth that one or two clients are subsidising the rest - which is where the conversation about re-pricing or firing a client starts. Run quotes through the agency pricing calculator to model the margin before you commit to the price.
