Independent Practice: Markup vs. Margin Mastery

Time to build fluency with markup and margin calculations! You'll work through problems that vary the numbers algorithmically until you can calculate both percentages reliably. This is the same procedural fluency you'll need for break-even analysis in the next lesson.

Markup Formula

(Price - Cost) ÷ Cost × 100%

Profit as % of what you paid

Margin Formula

(Price - Cost) ÷ Price × 100%

Profit as % of what customer pays

Why This Matters for Break-Even

Once you can calculate margin reliably, you're ready for break-even analysis. The key connection: margin tells you how much of each revenue dollar is profit available to cover fixed costs.

Contribution Margin

Your margin on each project is the "contribution" it makes toward covering Sarah's fixed costs (office, salary, insurance). Every project at 40% margin contributes $0.40 of each dollar toward the fixed cost floor.

Break-Even Formula

Fixed Costs ÷ Contribution Margin = Break-Even Point (in units or dollars) You'll practice this in Lesson 3 — but first, make sure markup and margin calculations are automatic.

What Sarah Now Knows

With reliable markup and margin skills, Sarah can quickly evaluate any pricing proposal, understand what percentage of revenue she actually keeps, and defend her prices to investors using the language they speak: margin.
