5.4 Costs – Uses of Cost Information 📊

Why Do We Care About Costs? 🤔

Costs are the money a business spends to make a product or service. Knowing these costs helps managers decide how much to charge (pricing) so the business stays profitable.

1️⃣ Types of Costs

Cost Type	Definition	Example
Variable Cost	Changes with output level.	Raw materials for a T‑shirt.
Fixed Cost	Stays the same regardless of output.	Rent for the factory.
Semi‑Variable Cost	Has a fixed part + a variable part.	Utility bill: base fee + usage charge.

2️⃣ Cost Behaviour & Contribution Margin 📈

To price a product, managers look at the Contribution Margin (CM), the amount left after covering variable costs to help pay fixed costs and profit.

Formula: $CM = P - VC$ where $P$ = selling price, $VC$ = variable cost per unit.

Exam Tip: When asked to calculate CM, remember to subtract variable cost from price, not total cost.

3️⃣ Break‑Even Analysis ⚖️

The break‑even point (BEP) is where total revenue equals total cost.

Formula: $BEP = \frac{FC}{CM}$ (units)

Example: A company has fixed costs of $10,000, variable cost per unit $5, and sells each unit for $15.

CM = $15 - $5 = $10
BEP = $10,000 / $10 = 1,000 units

Exam Tip: Show all steps in your calculation and state the unit of the BEP.

4️⃣ Pricing Strategies 🎯

Cost‑Plus Pricing – Add a markup to total cost.
Markup Pricing – Add a fixed percentage to cost.
Target‑Price Pricing – Set price based on market demand, then calculate required cost.
Competitive Pricing – Price in line with or below competitors.

Analogy: Think of pricing like setting a price tag on a pizza 🍕 – you need to cover the cost of dough, cheese, toppings (variable costs), the pizza oven rent (fixed cost), and still leave room for profit.

5️⃣ Example: Pricing a Custom T‑Shirt 👕

Item	Cost ($)
T‑Shirt fabric (variable)	3
Printing (variable)	2
Factory rent (fixed)	500
Total Cost per unit	5

Suppose the company wants a 40% markup on cost.

Markup amount = $5 × 0.40 = $2

Price = $5 + $2 = $7

Exam Tip: When a question asks for “markup percentage,” calculate it as $Markup = \frac{Price - Cost}{Cost}$.

6️⃣ Summary of Key Points 📌

Know the difference between variable, fixed, and semi‑variable costs.
Use contribution margin to assess pricing impact.
Calculate break‑even to understand sales volume needed.
Choose a pricing strategy that fits the market and cost structure.
Always show your calculations clearly in exam answers.

Final Exam Tip 🚀

When answering pricing questions:

State the cost components.
Show the chosen pricing method.
Calculate the price step‑by‑step.
Explain how the price covers costs and gives profit.

Good luck, future business leaders! 🎓
