What to do with this result
Reset scope or pricing for consistently over-serviced accounts; check whether non-hours-based deliverables make an hourly retainer comparison misleading.

Planning model, not personalized financial advice. Your inputs remain in your browser.
Calculation method
Monthly contribution = clients × [retainer fee + max(0, actual hours − included hours) × overage rate × collection share − actual hours × delivery cost].
Assumptions and limitations
- Example inputs are editable scenarios, not Aryo results or independently verified industry benchmarks.
- Use collected revenue and fully loaded delivery costs consistently. Released time is capacity, not automatically a cash saving.
