Agency retainer pricing calculator

Enter the retainer, the hours and the costs. See whether it pays and what fee would give your target margin.

A retainer is only as good as the hours behind it. Enter the monthly retainer, the hours the account takes, your cost per team hour and any other costs, and the calculator shows the margin you keep and the retainer that would reach your target margin. It also shows how many accounts your team can carry at those hours, which helps when deciding whether to take another client. Check the retainer again whenever the scope grows. The glossary entry on the retainer explains the term, and the pricing models guide covers alternatives.

How it works

How to use the result

The default numbers are placeholders based on the 4-account scenario behind Cofoundr's time calculator, about 23.5 routine hours per account a month. Replace them with your own, measured over two weeks, for a real answer.

Common questions

How much should a retainer cover?

At minimum the cost of the hours and other direct costs for the account, plus the margin you need. Hours that grow over time can quietly erode a fixed retainer, so review it regularly.

Where do my hours come from?

Track time per account for two weeks in three buckets: routine checking and diagnosing, reporting, and strategy and client contact.

Is a high margin always good?

Not if quality suffers. Protect strategy time for each client, since that is what retains them.

Does this include tools and other costs?

Yes, if you enter them. Put tools, freelancers and creative costs for the account in other direct costs. Leave it at 0 to count only the cost of team hours.

What is effective hourly rate?

The fee divided by the hours the account takes. If it is below your cost per team hour, the account loses money before any other cost.
