How This Is Calculated
Contribution margin (price minus variable cost) determines profit per unit before fixed costs, and — combined with fixed costs — determines both current profit at a given volume and the target sales volume needed to hit a specific profit goal.
Frequently Asked Questions
What is the difference between contribution margin and gross margin?
▼
Contribution margin separates costs into fixed and variable, isolating the profit contributed by each unit sold (price minus variable cost only). Gross margin (revenue minus cost of goods sold) doesn't make this fixed/variable distinction and includes some costs that contribution margin analysis treats separately.
How is target sales volume for a specific profit goal calculated?
▼
(Fixed costs + target profit) ÷ contribution margin per unit — this extends the basic break-even formula (where target profit is zero) to solve for the volume needed to hit any specific profit target, not just to break even.

Evidence and verification checklist
- Confirm the current, in-force text governing Contribution Margin, Markup and Profit Calculator on the official source linked above - the summary on this page is an implementation aid, not a substitute for it.
- Record the exact event/transaction date, since the applicable version of the law, form or threshold can change between the date of the underlying event and today.
- Preserve the primary documents (notices, applications, orders, acknowledgements) that would let a reviewer reconstruct how the facts were classified and what was actually done.
- Check for a State-specific rule, later amendment or binding judicial decision that may modify how this applies on your facts.
Before relying on this page
This page is a structured implementation summary, not the operative legal text. Portal or process acceptance of a filing does not by itself establish legal compliance - the underlying classification, authority, evidence and timeline still have to be independently correct. Where the facts are contested, high-value, or time-barred if delayed, verify the current position with the official source and, where appropriate, a qualified professional before acting.
Methodology, assumptions and sources
Scope: Computes contribution margin, contribution margin ratio, and markup/margin conversions for pricing and profitability analysis.
Calculation logic
- Contribution margin per unit = Selling price − Variable cost per unit.
- Contribution margin ratio = Contribution margin per unit ÷ Selling price, expressed as a percentage.
- Markup percentage = (Selling price − Cost) ÷ Cost; Margin percentage = (Selling price − Cost) ÷ Selling price — the calculator converts between the two on request, since they are frequently confused.
Inputs and assumptions
- Variable cost is whatever the user classifies as variable (direct material, direct labour, variable overhead); fixed costs are excluded from this per-unit calculation by design.
- Markup and margin are mathematically related but not equal — the calculator shows both to avoid the common confusion between the two.
Exclusions and edge cases
- Does not perform full absorption costing (fixed overhead allocation per unit) — this is a variable/contribution costing tool.
- Multi-tier discounting or volume-based pricing is not modelled unless the user runs the calculation at each price point separately.
