Use cost, not billing rate
Internal hourly cost should reflect the cost assumption used for planning, not the price charged to the client.
Project Cost and Profitability Calculator
Estimate delivery cost, contingency, gross profit, and margin before committing to a client project. No invoice creation or financial advice.
Use the output as a decision draft.
Keep pass-through costs visible
Production, travel, software, suppliers, and other external costs can change the margin materially.
Protect uncertainty
A contingency makes known uncertainty visible but does not replace a clear scope-change path.
Review after delivery
Compare planned and actual effort, cost, revenue, and scope so the next estimate improves.
What to know before using it.
Is this accounting or financial advice?
No. It is a planning estimate. Confirm accounting treatment, tax, payroll burden, currency, overhead, and reporting definitions with qualified owners.
What is gross margin?
This tool divides estimated gross profit by the proposed fee. Your organization may use a different contribution or net-margin definition.
Does contingency increase the client fee?
The calculator applies contingency to estimated delivery and external cost. Whether and how that affects pricing is a commercial decision.
