Budgeting & Forecasting › Flexible Budgets
How does flexible budgeting interact with absorption vs marginal costing?
IntermediateAnswer
Under marginal costing, flexing focuses on variable costs and contribution, with fixed costs treated as a period lump sum. Under absorption costing, fixed overhead is absorbed per unit, so flexing and variance analysis include a fixed-overhead volume variance. The costing system affects how the flexed budget and variances are presented.
Real-world example The flexed statement under absorption costing shows an under-absorption of fixed overhead at lower volume.
