ASCM-L11 — Contribution & Profit Analysis
Understanding how contribution is used to analyse profitability, support decision-making, and evaluate business performance.
Learning Objectives
By the end of this lesson students should be able to:
• understand contribution analysis
• calculate total contribution
• calculate contribution per unit
• calculate profit using contribution
• analyse profitability
• answer examination-style questions
CONCEPT OVERVIEW
What is Contribution?
Contribution is the amount remaining after variable costs have been deducted from sales revenue.
Contribution helps cover fixed costs and generate profit.
Why is Contribution Important?
Managers use contribution to:
✓ assess profitability
✓ support pricing decisions
✓ compare products
✓ evaluate performance
✓ support future planning
CORE FORMULAE
Contribution
Contribution=Sales Revenue−Variable Costs\text{Contribution}=\text{Sales Revenue}-\text{Variable Costs}
Contribution Per Unit
Contribution per Unit=Selling Price−Variable Cost per Unit\text{Contribution per Unit}=\text{Selling Price}-\text{Variable Cost per Unit}
Profit
Profit=Contribution−Fixed Costs\text{Profit}=\text{Contribution}-\text{Fixed Costs}
CONTRIBUTION ANALYSIS
Interpretation
High contribution generally indicates:
✓ greater ability to cover fixed costs
✓ higher profit potential
✓ stronger product performanceDecision-Making Use
Managers often compare products using contribution rather than sales revenue alone.
A product with higher sales may not always generate higher contribution.
ADVANTAGES & LIMITATIONS
Advantages
✓ Easy to calculate
✓ Supports decision-making
✓ Assists profit analysis
✓ Highlights product performance
✓ Useful for planningLimitations
✓ Ignores qualitative factors
✓ Depends on accurate cost classification
✓ Focuses mainly on short-term decisions
✓ Does not consider capacity constraintsWORKED EXAMPLES
Example 1 — Contribution Per Unit
Selling Price:
£30
Variable Cost:
£18
Contribution:
£12 per unit
Example 2 — Total Contribution
Sales Revenue:
£240,000
Variable Costs:
£150,000
Contribution:
£90,000
Example 3 — Profit Analysis
Contribution:
£90,000
Fixed Costs:
£55,000
Profit:
£35,000
COMPARING PRODUCTS
Product Comparison Example
| Product | Contribution per Unit |
|---|---|
| A | £8 |
| B | £12 |
| C | £5 |
Based on contribution alone:
1. Product B
2. Product A
3. Product C
Product B contributes the most towards fixed costs and profit.
CONTRIBUTION TO SALES RATIO (C/S RATIO
Formula
C/S Ratio=Sales RevenueContribution×100
Example
Contribution:
£40,000
Sales Revenue:
£100,000
C/S Ratio:
40%
Interpretation
A higher C/S ratio indicates that a larger proportion of sales revenue contributes towards fixed costs and profit.
Structured Practice

Detailed Activity Solutions
Solution to Level 3 question
a)
Contribution
£180,000 − £108,000
= £72,000
b)
Profit
£72,000 − £42,000
= £30,000
c)
C/S Ratio
(£72,000 ÷ £180,000)
× 100
= 40%
