## Formula

Job cost = Direct materials + Direct labour + (Overhead rate × Allocation base) + Other direct costs

- Job cost = Direct materials + Direct labour + (Overhead rate × Allocation base) + Other direct costs.
- Inputs used: Currency, Direct materials charged to the job, Direct labour charged to the job, Your overhead rate per base unit, Allocation base the job used, Other direct costs (optional), Good units produced on the job (optional).
- Edge handling: Direct materials charged to the job is required.; Direct materials charged to the job cannot be negative.; Direct materials charged to the job must be no more than 1000000000000.; Direct labour charged to the job is required.; Direct labour charged to the job cannot be negative..

## Inputs

- Currency
- Direct materials charged to the job
- Direct labour charged to the job
- Your overhead rate per base unit
- Allocation base the job used
- Other direct costs (optional)
- Good units produced on the job (optional)

## Worked example: A job with materials, labour and applied overhead

Overhead is applied with your own rate; no rate is assumed for you.
1. Start with Currency: USD, Direct materials charged to the job: 4200, Direct labour charged to the job: 3100, Your overhead rate per base unit: 24, Allocation base the job used: 120, Other direct costs (optional): 0.
2. Apply the method: Job cost = Direct materials + Direct labour + (Overhead rate × Allocation base) + Other direct costs.
3. Overhead is applied with your own rate; no rate is assumed for you.

## Common questions

### Where does this formula come from?

Principles of Accounting, Volume 2: Managerial Accounting (OpenStax) — job cost is direct materials plus direct labour plus overhead applied at a predetermined rate; unit cost is total production cost divided by the units produced. See the source link on this page.

### What kind of calculation is this?

Job order costing: the costs traced to a job plus overhead applied with the organisation's own predetermined rate. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Arithmetic over the figures entered — it cannot tell whether the costs, standards or allowances behind them are right. A target cost, an industry benchmark and the organisation's own standard are different things; only the figures entered are used. Overhead is applied, not actual; any over- or under-applied overhead is settled outside this calculation.

### How do I use the Job Cost Calculator?

Enter the required values for Currency, Direct materials charged to the job, Direct labour charged to the job, Your overhead rate per base unit, Allocation base the job used, 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 Job Cost Calculator use?

Job cost = Direct materials + Direct labour + (Overhead rate × Allocation base) + Other direct costs 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 Job 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 job cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
