Project profit calculator: enter figures and review the result
Enter Project revenue, Materials / direct costs, Allocated overhead, Labor hours, and Labor rate per hour. The calculator returns pre-tax profit, estimated tax, project profit, project margin, and total project costs from the values you enter.
How to use the calculator
- Enter values in Project revenue, Materials / direct costs, Allocated overhead, Labor hours, and Labor rate per hour. The five fields must not be blank. Revenue must be greater than 0; the other four values can be 0 or more.
- Enter Estimated tax rate % (optional), or leave it blank. A blank value is treated as 0. Values from 0 to below 100 are accepted by the calculator.
- Choose a Period label and Currency symbol. These affect the result labels or formatting; they do not convert the figures. Keep all entries on the same basis.
- Select Calculate project profit. If validation fails, calculation stops, an error appears, and the result section stays hidden.
How the calculation works
The calculator uses these formulas:
Labor cost = Labor hours × Labor rate per hourTotal project costs = Materials + Labor cost + Allocated overheadPre-tax profit = Project revenue - Total project costsEstimated tax = Pre-tax profit × Tax ratewhen pre-tax profit is positive; otherwise it is 0.Project margin % = Project profit ÷ Project revenue × 100
Displayed money values use two decimal places; percentages display up to two decimal places.
What appears in the result
The result includes headline statistics, an assumptions table, and the formula display. The table shows entered numeric figures and calculated values, including labor cost, total project costs, pre-tax profit, estimated tax, project profit, and margin. The selected period appears in labels, while the currency symbol is applied to formatted values rather than listed as a separate row.

Limits and data handling
- The calculator uses only the figures you enter. It does not fetch market prices, wage benchmarks, or other external data.
- The Period label does not convert figures between periods. Use a consistent basis for revenue, costs, hours, and overhead.
- The optional tax value is a single flat-rate estimate applied only to positive pre-tax profit. It does not determine actual tax liability.
- The local calculator script processes entered calculation values in the browser and does not submit those values through the calculator workflow. The assigned files do not establish the page’s complete analytics, logging, or server-side privacy behavior.
Frequently asked questions
What is the project profit formula?
Project profit = Project revenue - (Materials + Labor cost + Allocated overhead). Labor cost is labor hours multiplied by labor rate per hour. If an estimated tax rate is entered, it is applied to a positive pre-tax profit before arriving at the final project profit figure.
What counts as allocated overhead?
Allocated overhead is the share of your fixed business costs - rent, admin staff, software, insurance, and similar - that you attribute to this specific project, rather than a cost tied directly to producing it. You decide the allocation method and enter the resulting dollar figure.
Is the tax figure my actual tax liability?
No. The optional tax field applies a single flat percentage to a positive pre-tax profit for planning purposes only. It does not reflect tax brackets, deductions, credits, entity structure, or jurisdiction-specific rules, and does not determine actual tax liability.
What period should I use for the inputs?
Choose the period label that matches the basis of your figures: Per project, Monthly, Quarterly, or Annual. The selector labels the result but does not convert values, so keep revenue, labor hours, materials, and overhead on the same basis.
Does this tool fetch market data or give personalized advice?
No. It performs a single calculation using only the numbers you type in - revenue, materials, labor hours and rate, overhead, and an optional tax rate. It does not fetch market prices, wage benchmarks, or cost data, and it is not personalized financial, pricing, or tax advice.
