What is client profitability?
Client profitability measures how much money your agency actually keeps from a client after accounting for the costs required to deliver their work. A client can generate significant revenue and still be unprofitable if the account consumes too many employee hours, requires excessive revisions, or creates a large amount of unbilled work.
This is particularly important for marketing agencies that sell services on monthly retainers. A $5,000 monthly client sounds valuable until you discover that the account requires 80 hours of work every month at a $50 loaded labor cost. Add software, meetings, revisions, and unbilled work, and the actual margin can be dramatically lower than expected.
Looking at revenue alone can therefore give agency owners a misleading picture of which clients are worth keeping. Client profitability combines revenue with the actual cost of delivering the work, giving you a clearer picture of which accounts are healthy, which need to be repriced, and which may be costing your agency money.
How to calculate agency client profitability
The basic formula for calculating client profit is:
To get a useful estimate, you need to account for several components of the client relationship:
Client revenue
The monthly revenue your agency receives from the client, including recurring retainers and other recurring client revenue.
Total client hours
The total time your team spends delivering work for the client. Include strategy, production, meetings, revisions, account management, and other client-related work.
Unbilled hours
Time your team spends beyond the agreed scope without charging the client. These hours are especially important because they represent a real delivery cost without generating additional revenue.
Loaded labor cost
Your approximate cost for one hour of employee labor, including salary, payroll taxes, benefits, and an appropriate share of overhead.
Client-specific software costs
Software, subscriptions, contractors, or other recurring costs that can reasonably be attributed to a specific client.
Profit margin
Client profit expressed as a percentage of client revenue. This makes it easier to compare the profitability of clients with different monthly revenues.
Effective hourly rate
Client revenue divided by the total hours your team spends servicing the account. This shows what you're effectively earning for every hour of agency labor.
What is a good agency client profit margin?
There isn't one universal client profit margin that works for every agency. Service mix, employee costs, pricing model, utilization, and overhead all affect the appropriate target.
What matters most is understanding the economics of each account and comparing clients consistently. Two clients paying the same $5,000 monthly retainer can have completely different economics if one requires 25 hours of work and the other requires 70.
A declining margin can also be an early warning sign. If an account becomes increasingly demanding without a corresponding increase in revenue, your agency may be absorbing scope creep without realizing how much it is costing you.
Why unbilled hours destroy agency profitability
Unbilled work is one of the easiest ways for an agency to lose margin without noticing it. A few extra hours of work each month might seem insignificant, but repeated across a client portfolio, those hours can represent thousands of dollars in lost profit.
Unbilled work often comes from scope creep, additional revisions, missing client information, delayed approvals, or teams spending time following up with clients. The work still consumes employee time even though it doesn't appear as additional revenue.
Tracking these hours gives agency owners a better understanding of the true cost of servicing an account—and provides evidence when it's time to adjust scope, pricing, or the client workflow.
How to improve client profitability
Improving client profitability isn't always about increasing prices. Agencies can also improve margins by reducing wasted delivery time, controlling scope creep, improving utilization, and making it easier for clients to provide the information and approvals their teams need.
One frequently overlooked source of wasted time is client follow-up. Teams spend hours asking clients for missing assets, chasing approvals, searching through email attachments, and figuring out what information is still outstanding.
Once you've identified an unprofitable client, the next problem is figuring out why projects keep getting delayed or why your team keeps having to chase the client for assets, approvals, and information.
Stop chasing clients for the information you need.
Piqqi gives agencies a dedicated client workspace for collecting files, approvals, signatures, and requests. Automated reminders keep clients moving so your team spends less time following up and more time delivering work.

What is a client profitability calculator?
A client profitability calculator estimates how much profit an agency actually makes from a client after accounting for labor costs, software costs, and other delivery expenses.
How do you calculate the profitability of an agency client?
Subtract the labor and client-specific costs required to service the account from the revenue generated by the client. Divide the resulting profit by revenue to calculate the client's profit margin.
Should unbilled hours be included in client profitability?
Yes. Unbilled hours still consume employee time and therefore represent a real delivery cost. Including them gives you a more accurate picture of the client's true profitability.
What is loaded labor cost?
Loaded labor cost is the estimated cost of an employee's time after accounting for salary plus costs such as payroll taxes, benefits, and overhead.
Why can a high-revenue client be unprofitable?
A high-revenue client can still be unprofitable when the account requires too many hours, generates excessive scope creep, requires substantial unbilled work, or has unusually high delivery costs.
