Pricing retainers that survive contact with the work

A retainer is a promise about capacity, so it should be priced from capacity data. The common failure is pricing from an optimistic average month — the one where the client was decisive and no revision rounds ran long.

Start with the last six months of actual hours on comparable accounts. Take the 75th percentile, not the mean. That single change turns most 'why is this account never profitable' conversations into a solved problem, because you have priced the month that actually hurts rather than the month you hoped for.

Next, write down the capacity you are reserving, in hours, in the contract. Retainers phrased purely as deliverables invite scope drift with no natural place to push back. Retainers phrased as reserved hours give both sides a shared unit of measurement.

Then set a trigger, not a grudge. Something like: if actual hours exceed the reserved block by 15% for two consecutive months, we review the block size. Clients accept this readily when it is agreed up front and almost never when it arrives as a surprise invoice.

Finally, review retainers on a fixed calendar — every six months, whether or not anything feels wrong. The studios with the best retainer margins are not better negotiators. They just look at the numbers on a schedule.
