VARIABLE COSTING ARLAN C. FAJARDO
JOSEPH
Basic principles
Variable costing is the same as marginal costing, direct costing, or contribution margin costing.
Variable costing is an extension of CVP analysis.
The basic assumptions in the marginal costing (i.e., CVP analysis) are followed except that production is not equal to sales.
Technically speaking, variable costing and direct costing are different. Variable costing includes -variable production costs as part of the product cost while direct costing includes all costs directly identified with the segment as product costs- Another, variable costing focuses on the contribution margin while direct costing zeroes-in on segment margin.
The unit costs from the preceding period are the same in the current period; meaning, unit costs are assumed to be constant
Treatment of fixed overhead, and other costs and expenses
Under
absorption costing, fixed overhead is a product cost, inventoriable costs, or deferrable costs. This means theft the cost assigned to- the product is charged against sales when the units are sold, and is still deferred in the inventory when the units are still unsold. This follows toe principle of matching of costs against revenues.
Under variable costing, fixed overhead is a period cost, meaning,
outright an expense. This means the fixed overhead is immediately charged against revenues without regard as to whether the units are already sold or stiff unsold. This follows the immediate recognition principle. The rationale for this treatment is because the fixed overhead would be incurred regardless of whether the production occurs or not, and therefore, should not be treated as product cost.
Direct materials, direct labor, and variable overhead -are product
costs, both to absorption and variable costing systems.
Variable expenses and fixed expenses are period costs> both to
absorption and variable costing-systems. Computation guidelines

Costs variances are treated as follows: PAGE 2 OF 27
UF costs variances are added to CGS at standard or deducted from operating income.
Favorable costs variances are deducted from CGS at standard or added to operating income.
Volume variance is included only in the absorption costing operating income.

Sales and variable costing, production and absorption costing
(Which follows which?)
Variable costing income follows sales; that is: If VC Operating Income VC Operating Income is Sales > Production Increases Greater than AC Sales < Production Decreases Lower than AC Absorption costing income follows production; that is: If AC Operating Income AC Operating Income is Production > Sales increases Greater than VC Production < SalesDecreases Lower than VC STRAIGHT PROBLEMS 1.
