Gross margin
6.1 Calculation and Understanding of Accounting Ratios
Gross Margin 📈
Gross margin tells you how much money a company keeps from each sale before paying for the items it sells. Think of it as the “profit cushion” that covers other costs like salaries, rent, and marketing.
Analogy: Lemonade Stand 🍋
Imagine you run a lemonade stand.
- 💰 Sales revenue: Money you get from selling cups of lemonade.
- 🧃 Cost of goods sold (COGS): Money spent on lemons, sugar, and cups.
- 💵 Gross profit: Sales revenue minus COGS.
- 📊 Gross margin %: Gross profit divided by sales revenue, expressed as a percentage.
Formula & Calculation
The formula for gross margin is:
$Gross\ Margin = \frac{Sales - Cost\ of\ Goods\ Sold}{Sales} \times 100\%$
- Subtract COGS from Sales to get Gross Profit.
- Divide Gross Profit by Sales.
- Multiply by 100 to get a percentage.
Example: Lemonade Stand
Suppose in one month you sold 1,000 cups of lemonade for $2 each, and the cost of lemons, sugar, and cups was $1,200.
- Sales = 1,000 × $2 = $2,000
- COGS = $1,200
- Gross Profit = $2,000 – $1,200 = $800
- Gross Margin = ($800 ÷ $2,000) × 100% = 40%
Interpretation & Use
- 📈 A higher gross margin indicates better efficiency in producing goods.
- 💡 Helps set selling prices: if the margin is too low, consider raising prices or reducing costs.
- 🔍 Useful for comparing companies in the same industry.
