Which description best describes marginal costing usage in CVP analysis?

• A. Used to assess the effect of volume on contribution
• B. Ignore fixed costs
• C. Assumes selling prices vary with volume
• D. Is the same as standard costing

Answer: (A)

In CVP analysis using marginal costing, the focus is on contribution, which is the selling price per unit minus the variable cost per unit. Total contribution equals that per-unit contribution times the volume. Fixed costs stay the same in the short term, so as volume changes, total contribution changes and determines profit once fixed costs are covered. This is why the description that it is used to assess the effect of volume on contribution is the best fit. Fixed costs aren’t ignored here; they’re what the total contribution must cover to achieve profit, so they matter for break-even and overall profitability. Selling prices are assumed to be constant, not varying with volume. And marginal costing differs from standard costing, which uses standard costs and variances rather than focusing on contribution to cover fixed costs.
