What this calculator does
The Client Profitability Calculator helps agencies move from top-line revenue tracking to true client-level margin analysis. A high retainer does not always mean high profit when account teams are over-servicing or overhead allocation is unclear. This tool lets you enter monthly retainer value, labor hours, average hourly cost, and overhead percentage to estimate gross profit and effective hourly rate. Use it during quarterly account reviews to identify clients that need repricing, scope control, or process automation. It is especially useful for founders and operations leads managing growth, where hidden margin leakage can stall hiring plans. With one quick calculation, you can prioritize accounts that support healthy growth and flag relationships that need structural changes.

Why this matters for agencies
When agencies measure only revenue, unprofitable clients stay hidden. Profitability analysis protects capacity, staffing plans, and long-term retention. It also gives account managers objective data to support scope conversations and pricing adjustments.
Frequently asked questions
What profit margin should agencies target per client?
Many agencies target 30% to 50% gross margin per client, depending on service mix, seniority requirements, and growth stage.
Why include overhead in client profitability?
Overhead captures non-delivery costs like management time, software, and admin operations that reduce real margin.
How often should I review client profitability?
Quarterly reviews are common, but fast-growing agencies often check monthly to catch margin drift early.
Can this support pricing discussions?
Yes. Showing effective hourly rate and profit margin helps justify retainer adjustments with objective numbers.
