Agency client margin calculator

agency client margin calculator. Most agencies track revenue per client but not true margin. This calculator shows margin dollars, margin percent, and annual profit per client in 30 seconds — what you bill minus your own wholesale or product cost.

How to use this Agency margin calculator

1. Enter the monthly retainer. What this client pays you per month across everything you bill them.

2. Enter your monthly wholesale/product cost. What the services you resell to this client actually cost you each month, before your markup.

3. Enter how many clients like this. Optional — to estimate annual margin across a set of similar accounts.

4. Read the result. Margin per client per month in dollars and percent, plus annual margin for one client and across the set.

The Agency margin calculator

Why this matters

Revenue per client is easy to see; true margin per client almost never is — and that is the number that should drive pricing.

The biggest-billing client can be the thinnest-margin one. The calculator shows it in seconds.

HubWho is built to compute this automatically and on demand from your real invoices and the wholesale costs you enter, so you do not rebuild it in a spreadsheet every quarter.

Beyond the calculator
