## Formula

Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i)

- 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..

## Inputs

- 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

## Worked example: Three roles on one delivery

Each role's own loaded cost is entered; no standard rate is assumed.
1. 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.
2. Apply the method: Project labour cost = Σ (Hours of role i × Loaded cost per hour of role i).
3. Each role's own loaded cost is entered; no standard rate is assumed.

## 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.

## 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.
