Estimate agency profit leakage by driver

Enter conservative operating assumptions and see a directional estimate across gross margin, operating margin, overhead ratio, utilization gaps, write-offs, admin time, and recoverable leakage.

Planning view

Use this to find whether the visible pressure looks more like delivery cost, overhead, utilization, write-offs, admin leakage, or pricing/rate pressure.

How to interpret this tool

This calculator is a planning aid. It uses the assumptions you provide to estimate potential leakage. It is not financial, accounting, tax, legal, investment, or procurement advice, and it does not guarantee savings or profit improvement.

Calculator inputs

Agency profitability calculator

Estimate a directional planning view of agency margin, operating profit, utilization pressure, admin leakage, and recoverable operational leakage. Outputs are based on your inputs and should be validated against real finance and project data.

Business profile

Start with the agency model and the monthly revenue, delivery cost, payroll, and overhead assumptions you want to test.

Agency typeMonthly revenue

GBP

Use recurring and project revenue for the month you want to model.Monthly direct delivery costs

GBP

Freelancers, contractors, production costs, media, or third-party delivery costs where relevant.Monthly payroll cost for delivery team

GBP

Use loaded delivery payroll cost if available.Monthly overheads

GBP

Software, rent, management, admin, non-delivery salaries, finance, and operations.

Team and utilization

Estimate billable capacity and the value of the gap between current and target utilization.

Number of delivery team members

hours

Average blended billable rate

GBP/hour

Use the practical blended rate you use for planning, not a headline rate.

Leakage and admin

Capture the visible leakage that often hides inside retainers, project overruns, reporting, and handoffs.

Admin hours per week across the agency

hours

Repeated reporting, chasing, status updates, approvals, and coordination.Average internal hourly cost

Improvement assumption

Choose a conservative recoverable percentage for visible operational leakage.

Estimated recoverable leakage percentage

%

Use a conservative estimate. Not all leakage can or should be recovered.
