**Rows:**

**Method:** Absorption (full) costing

**Includes:** Direct material, direct labor, variable and fixed manufacturing overhead

**External:** Required under US GAAP and IFRS (IAS 2)

**Best:** Financial statements and tax

**Weakness:** Profit moves with production volume as fixed overhead shifts into inventory

**Method:** Variable (direct) costing

**Includes:** Direct material, direct labor, variable overhead only

**External:** Not acceptable for external statements

**Best:** Internal contribution analysis and short-term decisions

**Weakness:** Understates inventory and hides full cost in pricing

**Method:** Throughput (supercosting)

**Includes:** Direct material only; labor and overhead are period costs

**External:** Not acceptable for external statements

**Best:** Theory of Constraints bottleneck decisions

**Weakness:** Ignores real conversion cost over longer horizons

**Method:** Activity-based costing (ABC)

**Includes:** Overhead assigned through activity cost drivers

**External:** Acceptable if it yields full absorption cost

**Best:** Complex product mixes with diverse overhead use

**Weakness:** Costly to maintain and needs reliable driver data

**Method:** Standard costing

**Includes:** Predetermined standard material, labor and overhead

**External:** Acceptable if standards approximate actual cost (IAS 2)

**Best:** Repetitive production and variance control

**Weakness:** Stale standards distort margin and inventory value

**Method:** Actual costing

**Includes:** Actual material, labor and overhead of the period

**External:** Acceptable

**Best:** Custom, low-volume or cost-plus contract work

**Weakness:** Unit cost fluctuates with period volume and timing

**Method:** Normal costing

**Includes:** Actual material and labor plus overhead applied at a predetermined rate

**External:** Acceptable with period-end adjustment

**Best:** Smoothing overhead across uneven months

**Weakness:** Needs under and over absorption clean-up

**Method:** Job order costing

**Includes:** Costs accumulated per job or work order

**External:** Acceptable

**Best:** Job shops, aerospace parts, custom machinery

**Weakness:** Heavy transaction capture and job close discipline

**Method:** Process costing (weighted average)

**Includes:** Costs accumulated per department, averaged over equivalent units

**External:** Acceptable

**Best:** Continuous, homogeneous output such as chemicals

**Weakness:** Beginning WIP costs blend into current period

**Method:** Process costing (FIFO)

**Includes:** Current period costs separated from beginning WIP

**External:** Acceptable

**Best:** Processes needing period cost control

**Weakness:** More complex equivalent unit calculations

**Method:** Target costing

**Includes:** Allowable cost derived from market price minus required margin

**External:** Management tool, not an accounting basis

**Best:** New product design with fixed price points

**Weakness:** Needs strong cross-functional discipline

**Method:** Lean accounting (value stream costing)

**Includes:** Costs grouped by value stream, often with simplified inventory

**External:** Needs reconciliation to GAAP or IFRS

**Best:** Lean plants with low inventory

**Weakness:** Requires adjustments for statutory reporting

**Method:** Backflush costing

**Includes:** Costs flushed at completion or sale using standard bills of material

**External:** Acceptable if WIP is immaterial

**Best:** Just-in-time, short cycle production

**Weakness:** Weak audit trail within the production cycle

**Notes:** Summary guidance only. IAS 2 and ASC 330 both require the cost of inventory to include conversion costs allocated on normal capacity. Confirm treatment with your auditor.

## Content

**Intro:** Choosing a costing method changes reported profit, inventory value and the prices you quote. This table compares the main manufacturing methods on what they include, whether they can be used externally and where each one misleads.

**Sections:**

#### How to use the comparison

**Body:** Start with the reporting purpose. If you need statutory accounts, use the external column to filter to methods that produce full absorption cost. If you are deciding whether to accept an order, variable and throughput views are useful internally. Most plants run one method for the ledger and a second view for decisions, and the key is to reconcile them each period.

#### Absorption versus variable

**Body:** Under absorption costing, fixed overhead is attached to each unit produced, so units left in inventory carry a share of it. Under variable costing, fixed overhead is expensed in the period. When production exceeds sales, absorption profit is higher; when sales exceed production, it is lower. This single difference explains most arguments between operations and finance about a good or bad month.

#### When ABC and standards earn their cost

**Body:** Activity-based costing pays off when overhead is large and products consume it unevenly, for example high-mix electronics with varied setups. Standard costing pays off when production is repetitive and variances can be acted on. In both cases the quality of drivers and standards matters more than the method name.

#### Common mistakes

**Body:** Using variable costing figures in the statutory accounts, never updating standards, allocating overhead on direct labor hours when automation dominates, and comparing job cost across periods without adjusting for abnormal scrap or idle capacity.

**Cta:** If your ERP costing set-up does not match the method you think you run, we can help review the configuration.

**Faq:**

#### Which costing method does IFRS require?

**Answer:** IAS 2 requires inventory cost to include direct costs and a systematic allocation of fixed and variable production overhead, based on normal capacity. That is absorption costing, although standard or retail methods are allowed if they approximate cost.

#### Why do profits differ between absorption and variable costing?

**Answer:** Fixed overhead is deferred in inventory under absorption costing but expensed immediately under variable costing. Profit differs by the change in inventory units times the fixed overhead per unit.

#### Is throughput costing allowed for financial statements?

**Answer:** No. Throughput costing treats labor and overhead as period costs, so it understates inventory and does not meet IAS 2 or ASC 330. It is used internally to manage bottlenecks.

#### What is the difference between normal and standard costing?

**Answer:** Normal costing uses actual material and labor with predetermined overhead rates. Standard costing uses predetermined values for all three and records variances against them.
