Enter what each client pays and how many hours they actually take — we'll rank them by profit per hour so you know which retainers are worth keeping.
How this works
Divide what a client pays you per month by the hours you actually spend on them per month — including delivery, admin, and client-management time, not just billable calls. The result is profit per hour. Clients with a high monthly fee can still be your least profitable if they consume disproportionate time; clients with a modest fee can be your best if they're low-maintenance.
Everything: delivery work, calls, status updates, revisions, and the admin and context-switching overhead of managing the relationship. Consultants consistently underestimate this — a client who pays well but demands constant availability often has a worse profit-per-hour than a quieter, lower-fee client.
Not automatically — a low profit-per-hour client might still be strategic (a reference, a foot in the door, a stepping stone to bigger work). But if a client ranks at the bottom with no strategic upside, it's usually a signal to renegotiate scope or price, or to free up those hours for higher-profit work.
A rate calculator tells you what to charge going forward. A client profitability calculator looks backward at your existing book of clients and tells you which ones are actually delivering on that rate today, once real time spent is accounted for.
Retainer logs hours against every engagement so you always know which clients are actually worth the retainer.
