Agency Service-Mix Profitability Calculator
An agency service-mix profitability calculator shows whether your business is funded by all of your service lines or just one of them. Enter the monthly revenue and delivery cost for each type of work you sell — retainers, projects, ad management, or whatever your mix is — and it returns the gross margin per line and across the portfolio.

Which service type funds your business — and which one drains it.
What counts as delivery cost? ▸
Delivery cost = the hours your team actually works on this service line × your blended cost rate (salary + overhead share ÷ deliverable hours), plus any direct pass-throughs (subcontractors, software, ad spend counted as cost not revenue). Do not count ad spend that goes straight to the client's media account as revenue — include only your management fee.

Ascend logs time against each record as work happens, and invoices are generated from the same data — so hours by service type stay visible, not buried in a spreadsheet. Free plan included.

How to read your result
Two outputs matter most. Margin per service line tells you which type of work is actually paying the bills. A retainer might be 60% margin; a project line might be 18%. If you grow the wrong one, total revenue rises but profit compresses. Revenue share shows how much of your top line each service type represents — and helps you see whether a thin-margin line is also your biggest by volume. That combination is where the risk is.
How service-mix profitability is calculated
Each service line is treated as its own profit centre. For each line: gross profit = revenue − delivery cost, and margin = gross profit ÷ revenue. The portfolio margin is the weighted average across all lines — weighted by revenue, which is why a high-volume thin-margin service drags the portfolio down even when other lines look healthy.
Delivery cost is the hours your team actually works on that service line multiplied by your blended cost rate, plus direct pass-throughs. Check the cost helper inside the calculator for how to categorise ad management and subcontractor costs correctly.
A worked example
A three-person studio runs three service lines: retained social media management ($5,000/month, $1,800 delivery cost), web projects ($4,000/month, $2,800 delivery cost), and ad management ($3,000/month, $2,600 delivery cost).
- Social retainers: ($5,000 − $1,800) ÷ $5,000 = 64% margin
- Web projects: ($4,000 − $2,800) ÷ $4,000 = 30% margin
- Ad management: ($3,000 − $2,600) ÷ $3,000 = 13% margin
Total revenue $12,000; total cost $7,200; portfolio margin 40%. On paper the agency looks fine at 40%. But ad management is a $3,000 revenue line at 13% — the team is spending substantial hours generating $400 of gross profit. The social retainers are carrying the business. That is not visible until you run the service-mix view.
Why your revenue mix is not the same as your profit mix
The service lines that generate the most revenue are rarely the ones generating the most profit. Ad management and project work have high pass-through and unpredictable scope. Retainers have low variable delivery cost once the workflow is established. But retainers are harder to sell at scale than projects, which agencies therefore chase — and the margin never improves.
Running an agency service-mix profitability calculator on your actual numbers tells you which direction to push: which service types to grow, which to reprice, and which to quietly stop taking. The agency overhead rate calculator and client profitability calculator give you the upstream and per-client views of the same question.
What to do when your mix is wrong
You have three levers. Reprice the thin service line so it covers its true delivery cost, including scope creep that is normally absorbed silently. Rationalise delivery to cut hours without cutting output quality. Grow selectively toward higher-margin lines and let thin-margin volume shrink as a share of the total.
None of these moves requires a rebrand or a new target market. They require knowing which line is thin — which is what this calculator tells you. The agency hourly rate calculator is a useful next step if delivery cost is the problem.
Frequently asked questions
What is agency service-mix profitability?+
It is the analysis of gross profit and margin per service line within an agency's revenue — retainer work, project work, ad management, or other types. The service-mix view shows which type of work funds the business and which type consumes it.
Which agency service type typically has the highest margin?+
Retainer-based services tend to carry higher gross margins than project or ad-management work because the delivery process becomes more predictable and efficient over time. Project work margins erode with scope changes; ad-management margins depend heavily on whether hours are priced separately from the media spend pass-through.
How do I calculate gross margin for an agency service line?+
Gross margin for a service line = (revenue minus delivery cost) divided by revenue. Delivery cost is the hours your team spends on that line multiplied by your blended cost rate, plus any direct costs like subcontractors or software unique to that service.
Why does a profitable-looking agency sometimes run out of cash?+
Often because the high-revenue service line has low margins, while the high-margin line has limited volume. Total revenue masks the structural margin problem. The agency service-mix profitability calculator shows the root cause in the revenue mix.
Should I drop a low-margin service line?+
Not without checking two things first: what share of total revenue does it represent, and can you reprice or tighten delivery to raise the margin? Dropping a line abruptly removes revenue that might be covering shared overhead costs until the higher-margin line scales. Reprice first; exit only if the market won't support it.
How is this different from the project profitability calculator?+
The project profitability calculator and client profitability calculator analyse individual engagements or clients. This calculator analyses your revenue mix at the service-line level — how retainers, projects, and other service types compare to each other across the portfolio.
What counts as delivery cost for ad management services?+
Only your management fee is revenue. Include in delivery cost the hours your team spends on campaign setup, reporting, and client communication, multiplied by your cost rate. Do not include the media spend itself unless you are marking it up.
