I - Cost of Sales: General principles 

3. Proportional costs of sales

3.1. Definition

It includes the following reporting headings:

3.2. Proportional costs of sales - Standard (R15400)

For PF1 companies , these proportional (variable) costs of sales are ACTUAL costs.

For WP1 companies , they relate to STANDARD costs and correspond to:

Number of units sold during the period x unit standard variable cost

Unit standard variable cost is based on costing version of bill of material and recipe for the month. Costing version is the most likely version, based on cost analyst / production management judgment.

3.3. Actual/Standard variance - Proportional costs of sales (R15410)

For WP1 companies ONLY

See Standard Costing.

The variance is the difference between standard variable cost of units produced and actual variable cost during the period.

Variance are due to

  1. Performance :
  1. Cost centers :
  1. Inventory revaluation from current month standard to next month standard
  2. Purchase price : difference between raw material standard cost and actual cost

3.4. Content of the variable production cost

Proportional costs of sales include:

3.4.1. Acquisition cost = Purchase cost (less rebates and discounts obtained) + Incidental expenses

Note: By extension, in the case of "internal sales" (cross-divisions sale with an internal transfer price inside a company), the buying division considers it as an external purchase, i.e. fully variable

Are excluded from the acquisition cost:

3.4.2. Variable production cost

The cost of manufactured product inventories (finished products, work in progress etc.) includes the cost of purchase, the cost of conversion and other costs incurred in bringing the inventories to their current location and condition.

It includes:

Costs excluded from inventory valuation

Notes:

3.5. Semi-standard principle for the Production Cost

The semi-standard principle applies only for WP1 companies.
