Project Labor Cost Calculator
Add up what the people on a project cost, role by role.
In short
Add up what the people on a project cost, role by role.
Formula: Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i)
What this calculator does
Hours are multiplied by the loaded cost the firm enters for each role and summed. No standard rate, role mix or working year is assumed.
Use it to turn Currency, Role 1 — loaded cost per hour, Role 1 — hours on the project, Role 2 — loaded cost per hour, 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..
- Role 1 — loaded cost per hour
- — number value.
- Role 1 — hours on the project
- — number value.
- Role 2 — loaded cost per hour
- — Optional component. Leave at 0 to exclude it from the result..
- Role 2 — hours on the project
- — Optional component. Leave at 0 to exclude it from the result..
- Role 3 — loaded cost per hour
- — Optional component. Leave at 0 to exclude it from the result..
- Role 3 — hours on the project
- — 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
Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i).
Inputs used: Currency, Role 1 — loaded cost per hour, Role 1 — hours on the project, Role 2 — loaded cost per hour, Role 2 — hours on the project, Role 3 — loaded cost per hour, Role 3 — hours on the project.
Edge handling: Role 1 — loaded cost per hour is required.; Role 1 — loaded cost per hour cannot be negative.; Role 1 — loaded cost per hour must be no more than 1000000000000.; Role 1 — hours on the project is required.; Role 1 — hours on the project cannot be negative..
Worked example
Three roles on one delivery
- Start with Currency: USD, Role 1 — loaded cost per hour: 95, Role 1 — hours on the project: 320, Role 2 — loaded cost per hour: 140, Role 2 — hours on the project: 120, Role 3 — loaded cost per hour: 70.
- Apply the method: Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i).
- Each role's own loaded cost is entered; no standard rate is assumed.
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 labor cost 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?
Direct labour is accumulated per role, exactly as a job-order costing sheet accumulates direct labour. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
What are its limits?
Covers labour only; materials, travel and overhead belong in the project cost calculator. 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 Labor Cost Calculator?
Enter the required values for Currency, Role 1 — loaded cost per hour, Role 1 — hours on the project, Role 2 — loaded cost per hour, Role 2 — hours on the project, and the other fields shown. 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 Labor Cost Calculator use?
Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i) 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 Labor Cost 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
Direct labour is accumulated per role, exactly as a job-order costing sheet accumulates direct labour.
The question it answers: What will the people on this project cost us in total?
The formula
Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i)
- h_i — Hours of role i
- (h). Hours that role will spend on the project.
- r_i — Loaded cost per hour of role i
- (currency/h). Employer cost per hour for that role, entered by the firm.
Units: Hours; currency per hour; currency.
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
Hours are multiplied by the loaded cost the firm enters for each role and summed. No standard rate, role mix or working year is assumed.
Assumptions built into the result
- Mathematical: Loaded cost per hour already includes the employer costs the firm chooses to load.
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.
Limitations
- Covers labour only; materials, travel and overhead belong in the project cost calculator.
