The formula
Delivery cost = Hours × Loaded hourly cost + Other direct costs; Client contribution = Retainer − Delivery cost; Margin = Contribution / Retainer × 100.
Worked example
A ₹60,000 retainer using 50 hours at ₹600 plus ₹5,000 direct costs leaves ₹25,000 contribution (41.67%) and ₹1,200 revenue per delivery hour.
Frequently asked
Is client contribution net agency profit?
Only if every agency cost is fully allocated in the inputs. Otherwise it is the amount available to cover shared overhead and profit. Exclude pass-through ad spend from retainer revenue unless matching costs are included.
