Transparent method
How this calculation works
Reserved hours are multiplied by internal hourly cost, direct tools are added, and target margin is applied to solve the retainer.
Useful output
What you receive
Suggested retainer, delivery cost, gross profit, effective client rate, assumptions, and CSV.
Decision guardrail
What this does not decide
A retainer needs a clear scope and overage policy; this estimate does not prevent scope creep or utilization gaps.
