Retainer Margin Math: Which Clients Are Actually Profitable

Agency P&L looks fine in aggregate while a third of clients quietly lose money. Per-client contribution is the report most agencies never run on themselves.

The formula agencies avoid running

client_contribution = retainer − Σ(hours_logged × loaded_rate) − tools_allocated − media_management_overhead

Loaded rate, all roles, including the founder's hours — especially the founder's hours, which land on the squeakiest accounts and never get logged. Run it for a quarter and the distribution is almost always the same shape: a few great clients funding several marginal ones and two or three outright losses.

Why losses hide

Scope creep in slices — no single "extra ask" is worth a fight; sixty of them a quarter is a headcount.
Senior gravity — difficult accounts pull senior time, the most expensive hours, invisibly.
Anchor pricing — the retainer was set two years and three service-additions ago.

The quarterly decision, per client

Healthy (contribution > 40%) — protect: response times, senior attention, renewals.
Marginal (0–40%) — reprice against documented hours, or trim scope back to the contract. The hours log is the negotiation.
Negative — reprice with a real floor, or release. A released loss-making client is an immediate raise for the team that served them.

Reporting time is the swing factor

For most marginal clients, reporting and meeting-prep hours are the difference between the buckets. Cut report production from hours to minutes and a chunk of the marginal tier moves to healthy without a single pricing conversation — which is the cheapest margin repair available to an agency.

Track hours per client per function (delivery / reporting / comms) for one quarter before repricing anything. The data does the arguing.
