## Meaning and related methods

Actual costing uses actual direct rates and inputs, and actual overhead rates applied to actual driver usage. Shared costs still require allocation. BCAS 13, Appendix 13A distinguishes the methods below. [ICMAB, Bangladesh Cost Accounting Standards, Volume II, first edition November 2016, printed p. 35](https://web.icmab.gov.bd/media/assets/uploads/ckeditor/BCAS-II.pdf)

In the worked example applying the stated AASB 102 boundary, $10,000 of fixed overhead is spread over 1,000 normal-capacity hours at $10/hour. At 800 hours used, production absorbs $8,000 and **$2,000 remains unallocated**. Production cost is $45 per unit. Dividing all $38,000 of manufacturing spending by 800 units gives a separate management burden of $47.50 per unit. [AASB 102, paragraphs 13 and 38](https://standards.aasb.gov.au/aasb-102-dec-2021)

| System | Direct materials and direct labour | Manufacturing overhead |
| --- | --- | --- |
| Actual costing | Actual rates × actual inputs | Actual overhead rate × actual allocation-base usage |
| Normal costing | Actual rates × actual inputs | Predetermined overhead rate × actual allocation-base usage |
| Standard costing | Standard rates × standard inputs allowed for actual output | Standard allocation for actual output |

Normal costing is not the same concept as **normal capacity**, which is an inventory-valuation constraint discussed below. Nor does standard costing mean multiplying by budgeted output: the comparison concerns the actual output achieved. These are measurement approaches that can operate within job or process costing arrangements. [ICMAB, Appendix 13A](https://web.icmab.gov.bd/media/assets/uploads/ckeditor/BCAS-II.pdf)

The timing tradeoff matters. Actual overhead is not fully known when a job starts, while a predetermined rate permits earlier costing. The USDA's manufacturing costing guide describes normal costing as a compromise that estimates overhead while retaining actual direct costs. A report issued before payroll, supplier charges and allocations are complete should therefore identify its provisional elements. [USDA Forest Service, Product Costing Guide, NRS-140, December 2014, cost-control methods](https://www.govinfo.gov/content/pkg/GOVPUB-A13-PURL-gpo55867/pdf/GOVPUB-A13-PURL-gpo55867.pdf)

## Cost scope comes before calculation

For an ordinary inventory calculation, distinguish purchased materials, conversion costs and costs that belong directly in the period's expenses. The IFRS Foundation's IAS 2 overview includes purchase costs, direct labour, production overhead and other costs bringing inventory to its present location and condition. It also distinguishes specific identification from FIFO or weighted-average cost assignment, and requires the lower of cost and net realisable value. “Actual costing” alone does not select the cost-flow formula or remove the recoverability test. [IFRS Foundation, IAS 2 overview](https://www.ifrs.org/issued-standards/list-of-standards/ias-2-inventories/)

An important reporting boundary appears in Australia's AASB 102, December 2021 compilation, applicable to reporting periods beginning from January 1, 2022 through before January 1, 2027. Paragraph 13 bases fixed production-overhead allocation on normal capacity: low output or idle plant must not increase the fixed cost assigned per unit. Unallocated overhead is expensed. Variable production overhead follows actual facility usage. Paragraph 16 excludes abnormal waste, unrelated administration and selling costs from inventory. These are Australian reporting requirements, not a declaration that one valuation policy applies to every jurisdiction or management report. [AASB 102, paragraphs 12–16](https://standards.aasb.gov.au/aasb-102-dec-2021)

A management report may additionally show the full economic burden of unused resources. Keep that amount visible and reconcile it to inventory accounting; do not quietly change the inventory denominator to make every incurred cost disappear into units produced.

## Reconciled worked example

**Illustrative assumptions and arithmetic, not company rates:** one product, one month, USD, no beginning or ending work in process, no beginning finished goods, no abnormal waste, and no returns. All 800 completed units consume identical resources; 600 are sold and 200 remain. Actual production uses 800 machine-hours. Normal capacity is independently assessed at 1,000 machine-hours, with one hour per unit. Net realisable value exceeds cost. The example applies the normal-capacity allocation boundary above.

| Actual cost incurred | Amount | Treatment in this example |
| --- | ---: | --- |
| Materials consumed | $16,000 | Assigned to the 800 completed units |
| Direct labour | $8,000 | Assigned to completed units |
| Variable production overhead | $4,000 | Assigned using actual machine-hours |
| Fixed production overhead | $10,000 | Allocated using normal capacity |
| Selling and unrelated administrative costs | $3,000 | Period expense |
| **Total incurred** | **$41,000** | Reconciled below |

Variable-overhead rate = $4,000 ÷ 800 hours = **$5/hour**. Fixed-overhead allocation rate = $10,000 ÷ 1,000 normal-capacity hours = **$10/hour**. The production allocation is therefore $4,000 variable overhead plus $8,000 fixed overhead. The remaining **$2,000 fixed overhead** is an expense of unused capacity in this simplified case.

Completed production cost = $16,000 + $8,000 + $4,000 + $8,000 = **$36,000**, or **$45/unit**.

| Destination of the $41,000 incurred | Calculation | Amount |
| --- | --- | ---: |
| Cost of the units sold | 600 × $45 | $27,000 |
| Ending finished goods | 200 × $45 | $9,000 |
| Unallocated fixed overhead expense | $10,000 − $8,000 | $2,000 |
| Selling/administration expense | Given | $3,000 |
| **Total** | $27,000 + $9,000 + $2,000 + $3,000 | **$41,000** |

The $27,000 line identifies the inventory cost attached to sold units. A financial statement may also include unallocated overhead in its broader cost-of-sales presentation; AASB 102 paragraph 38 describes that distinction. If management divides all manufacturing spending by actual output, it obtains $38,000 ÷ 800 = **$47.50/unit**. That can describe this month's manufacturing burden, but using it to carry the 200 remaining units would produce $9,500 inventory, **$500 more** than the example's $9,000 valuation. Label the purpose of each metric. [AASB 102, paragraphs 13 and 38](https://standards.aasb.gov.au/aasb-102-dec-2021)

## Closing and interpreting actual costs

A practical costing record should connect the cost object and period to material issues/returns, production output, labour/resource usage and the associated costs. Oracle's Process Manufacturing documentation develops actual costs from recorded batch consumption and resource use rather than the planned recipe alone. It offers several period/perpetual averaging approaches. That is a software implementation example, not evidence that every available method satisfies every reporting framework. Check the selected valuation method, inventory balances and transaction cutoff together. [Oracle Process Manufacturing Cost Management, understanding cost types](https://docs.oracle.com/cd/E18727_01/doc.121/e13655/T388436T388440.htm)

An actual-cost close can coexist with standard prices during the month. SAP's Material Ledger training describes period-end actual prices and the roll-up of lower-level material differences through recorded consumption into higher-level products. It explicitly says actual costing is optional even where Material Ledger is active. Consequently, a standard-valued goods movement is not by itself proof that the final report excludes actual-cost adjustments. Verify the period, valuation view and closing status of the report being compared. [SAP, describing Material Ledger](https://learning.sap.com/courses/product-cost-planning-in-sap-s-4hana/describing-material-ledger)

When comparing normal or standard allocations with actual spending, separate spending changes from activity changes. ACCA demonstrates how fixed-overhead under/over absorption can arise from either expenditure or the amount of activity used to absorb overhead. A higher actual unit cost may therefore reflect lower utilisation rather than a deterioration in material price or shop-floor efficiency. Reconcile the total first, then investigate the component movements. [ACCA, fixed overhead absorption](https://www.accaglobal.com/uk/en/student/exam-support-resources/fundamentals-exams-study-resources/f2/technical-articles/overhead-absorption.html)

Actual costs describe recorded performance under a defined scope. For a future quote, adjust the assumptions about volume, prices, process and capacity explicitly rather than treating last month's unit result as a customer selling rate.
