What is the difference between the sales volume variance valued at contribution versus profit?

Advanced

Answer

Under marginal costing, the sales volume variance is valued at standard contribution per unit (since fixed costs don't change with volume). Under absorption costing, it's valued at standard profit per unit (contribution less fixed overhead per unit). The choice reflects the costing system and affects the reported variance magnitude.
Real-world example The same volume shortfall shows a larger adverse variance when valued at profit than at contribution.
