Project Gross Margin Calculator
See what share of a project's revenue survives its delivery cost.
In short
See what share of a project's revenue survives its delivery cost.
Formula: Gross margin = (Revenue − Direct cost) ÷ Revenue; Markup = (Revenue − Direct cost) ÷ Direct cost
What this calculator does
Margin and markup are reported separately from the same two figures so the two are never confused.
Use it to turn Currency, Project revenue, Direct project cost into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this professional & industry calculation.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Project revenue
- — number value.
- Direct project cost
- — number value.
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
Gross margin = (Revenue − Direct cost) ÷ Revenue; Markup = (Revenue − Direct cost) ÷ Direct cost.
Inputs used: Currency, Project revenue, Direct project cost.
Edge handling: Project revenue is required.; Project revenue cannot be negative.; Project revenue must be no more than 1000000000000.; Direct project cost is required.; Direct project cost cannot be negative..
Worked example
$120,000 project costing $78,000 to deliver
- Start with Currency: USD, Project revenue: 120000, Direct project cost: 78000.
- Apply the method: Gross margin = (Revenue − Direct cost) ÷ Revenue; Markup = (Revenue − Direct cost) ÷ Direct cost.
- Margin and markup are shown side by side so they are never confused.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this project gross margin calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions
Where does this formula come from?
OpenStax, Principles of Accounting Volume 2: Managerial Accounting — job order costing, cost-plus pricing, margin and markup. See the source link on this page.
What kind of calculation is this?
Gross profit expressed as a share of revenue, with the markup on cost shown alongside it. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
What are its limits?
Gross margin ignores overhead and administrative cost; use the net margin calculator for those. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
How do I use the Project Gross Margin Calculator?
Enter the required values for Currency, Project revenue, Direct project cost. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Project Gross Margin Calculator use?
Gross margin = (Revenue − Direct cost) ÷ Revenue; Markup = (Revenue − Direct cost) ÷ Direct cost The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
Can the Project Gross Margin Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
Formula, source and verification
Gross profit expressed as a share of revenue, with the markup on cost shown alongside it.
The question it answers: What share of this project's revenue is left after the cost of delivering it?
The formula
Gross margin = (Revenue − Direct cost) ÷ Revenue; Markup = (Revenue − Direct cost) ÷ Direct cost
- R — Project revenue
- (currency). Amount billed or expected for the project.
- C — Direct project cost
- (currency). Cost of delivering the project.
Units: Currency; percentages.
What kind of calculation this is
Deterministic formula. The same inputs always give the same answer. The maths is fixed and does not depend on judgement.
Method
Margin and markup are reported separately from the same two figures so the two are never confused.
Assumptions built into the result
- Mathematical: Revenue and cost cover the same scope.
Figures this calculator will never guess for you
- No industry-average rate, margin, overhead or ticket volume is inserted.
- No optional component is filled in on the user's behalf.
- Margin is never reported as markup or the reverse.
Limitations
- Gross margin ignores overhead and administrative cost; use the net margin calculator for those.
