10.2 Analysis of Published Accounts – Profitability Ratios

📊 Profitability ratios help us understand how well a company turns sales into profits. Think of them as the “health check” for a business’s earnings. In this lesson we’ll learn the main ratios, how to calculate them, what they tell us, and how a company can improve its profitability. 🚀

Key Profitability Ratios

• Gross Profit Margin – Shows the percentage of sales left after covering the cost of goods sold (COGS).

  \$ \displaystyle \text{Gross Profit Margin} = \frac{\text{Gross Profit}}{\text{Sales}} \times 100\% \$

• Net Profit Margin – Indicates the percentage of sales that becomes net profit after all expenses.

  \$ \displaystyle \text{Net Profit Margin} = \frac{\text{Net Profit}}{\text{Sales}} \times 100\% \$

• Return on Assets (ROA) – Measures how efficiently assets generate profit.

  \$ \displaystyle \text{ROA} = \frac{\text{Net Profit}}{\text{Total Assets}} \times 100\% \$

• Return on Equity (ROE) – Shows how well shareholders’ equity is used to produce profit.

  \$ \displaystyle \text{ROE} = \frac{\text{Net Profit}}{\text{Shareholders' Equity}} \times 100\% \$

Calculating the Ratios – Example

Let’s look at ABC Ltd. for the year 2024:

• Sales: £500,000
• COGS: £300,000
• Operating Expenses: £120,000
• Interest & Tax: £10,000
• Total Assets: £800,000
• Shareholders' Equity: £400,000

Step‑by‑step calculations:

1. Gross Profit = Sales – COGS = £200,000

   \$ \displaystyle \text{Gross Profit Margin} = \frac{200,000}{500,000} \times 100\% = 40\% \$

2. Net Profit = Gross Profit – Operating Expenses – Interest & Tax

   = £200,000 – £120,000 – £10,000 = £70,000

   \$ \displaystyle \text{Net Profit Margin} = \frac{70,000}{500,000} \times 100\% = 14\% \$

3. ROA = \$\displaystyle \frac{70,000}{800,000} \times 100\% = 8.75\% \$

4. ROE = \$\displaystyle \frac{70,000}{400,000} \times 100\% = 17.5\% \$

Interpreting the Ratios

• High Gross Profit Margin – The business keeps more of each sale after covering production costs.

• Low Net Profit Margin – Indicates high operating costs or poor pricing.

• ROA – A higher figure means the company uses its assets efficiently.

• ROE – Shows how well the company rewards its shareholders.

🧩 Analogy: Think of a lemonade stand. Gross margin is how much you keep after buying lemons and sugar. Net margin is what you keep after paying for the stand, electricity, and your friend’s share. ROA is like measuring how many cups you sell per square meter of the stand. ROE is how much profit you give back to the investors who helped you buy the stand.
