Which costing method is less reliant on accurate forecasting of production volumes?

• A. Marginal costing is less reliant
• B. Absorption costing is less
• C. They are equally reliant
• D. Neither relies

Answer: (D)

When you decide how to treat fixed overhead, you change how sensitive costs are to the amount you expect to produce. In marginal costing, fixed overhead is a period cost and is not included in the cost of individual units. Product costs consist only of variable costs. Because the unit cost doesn’t incorporate fixed overhead, it doesn’t shift with different production volumes, so it’s less affected by forecast accuracy for how much you’ll produce. In absorption costing, fixed overhead is allocated to units produced, so the fixed overhead included in each unit’s cost depends on the level of production. If your forecast for production changes, the fixed overhead per unit and the inventory valuation move accordingly. That makes this method more sensitive to how accurately you forecast production volume. Therefore, the approach that is less reliant on accurate production-volume forecasts is the marginal costing method, since it excludes fixed overhead from unit costs and treats it as a period expense.
