Project Net Margin Calculator
See what a project leaves after direct, overhead and administrative cost.
In short
See what a project leaves after direct, overhead and administrative cost.
Formula: Net margin = (Revenue − Direct cost − Allocated overhead − Other allocated cost) ÷ Revenue
What this calculator does
Only the indirect costs the firm allocates are subtracted; nothing is allocated automatically.
Use it to turn Currency, Project revenue, Direct project cost, Allocated overhead (optional), and the other shown inputs 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.
- Allocated overhead (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Selling, admin and other allocated cost (optional)
- — Optional component. Leave at 0 to exclude it from the result..
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
Net margin = (Revenue − Direct cost − Allocated overhead − Other allocated cost) ÷ Revenue.
Inputs used: Currency, Project revenue, Direct project cost, Allocated overhead (optional), Selling, admin and other allocated cost (optional).
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
Same project after overhead and admin cost
- Start with Currency: USD, Project revenue: 120000, Direct project cost: 78000, Allocated overhead (optional): 14000, Selling, admin and other allocated cost (optional): 6000.
- Apply the method: Net margin = (Revenue − Direct cost − Allocated overhead − Other allocated cost) ÷ Revenue.
- Only the indirect costs you allocate are subtracted.
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 net 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?
Revenue less all costs allocated to the project, expressed as a share of revenue. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
What are its limits?
The result depends entirely on the allocation method behind the amounts entered. 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 Net Margin Calculator?
Enter the required values for Currency, Project revenue, Direct project cost, Allocated overhead (optional), Selling, admin and other allocated cost (optional). 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 Net Margin Calculator use?
Net margin = (Revenue − Direct cost − Allocated overhead − Other allocated cost) ÷ Revenue 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 Net 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
Revenue less all costs allocated to the project, expressed as a share of revenue.
The question it answers: What does this project leave after overhead and administrative cost?
The formula
Net margin = (Revenue − Direct cost − Allocated overhead − Other allocated cost) ÷ Revenue
- R — Project revenue
- (currency). Amount billed or expected.
- C — Direct project cost
- (currency). Cost of delivery.
- O — Allocated overhead
- (currency). Optional overhead allocated to the project.
- A — Other allocated cost
- (currency). Optional selling and administrative cost allocated to 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
Only the indirect costs the firm allocates are subtracted; nothing is allocated automatically.
Assumptions built into the result
- Mathematical: Allocated amounts follow the firm's own allocation method.
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.
- No overhead percentage is applied when none is entered.
Limitations
- The result depends entirely on the allocation method behind the amounts entered.
