Gross Profit % on Cost of Sales (Markup)

Expressed as a percentage (%).

Why this ratio matters

This ratio matters because it shows the markup policy a trader applies when setting the selling price based on the cost of goods. The owner uses it to ensure every sale generates enough margin to cover operating expenses and produce a reasonable net profit. Creditors and suppliers also assess this ratio to judge how stable and sound a business's pricing policy is before extending credit. If the markup is found to be lower than the industry average, the owner may decide to revise the selling price or renegotiate purchase costs with suppliers.

Worked calculation

Perniagaan Maju Jaya recorded cost of sales of RM150,000 and gross profit of RM50,000 for the year ended 31 December 2024.

= RM50,000 ÷ RM150,000 × 100

= 33.33%

Interpretation for Paper 2

• For every RM100 of cost of goods, the business adds RM33.33 as gross profit.
• A stable markup from year to year shows a consistent pricing policy.
• This 33.33% markup can be compared with the average markup in the same industry to assess whether the business's selling price is competitive, or too high or too low relative to rivals.
• The trader can use this 33.33% markup rate as a basis to set the selling price of new products, by adding 33.33% on top of the cost of each unit of goods.
• This relatively high 33.33% markup may reflect strong bargaining power with suppliers, or a premium product positioning that can sustain a larger markup.

How to improve this ratio

• Negotiate a lower purchase price or bulk discount from suppliers to reduce the cost of sales without compromising the quality of goods.
• Control stock losses such as damage, theft and expiry more tightly so that the cost of sales incurred does not rise unnecessarily.
• Review and reasonably raise the selling price, or focus sales on higher-margin items, to increase the overall markup rate.

Common student mistakes

• Using the sales figure as the denominator instead of cost of sales. This gives the gross profit margin on sales, not the markup on cost.
• Forgetting to multiply by 100 after dividing gross profit by cost of sales, so the answer is left as a decimal instead of a percentage.
• Using the purchases figure alone as cost of sales without adding opening stock and deducting closing stock, so the cost of sales figure used is inaccurate.

Limitations

• It ignores operating expenses: a high gross profit does not always mean a high net profit.
• It is affected by the stock valuation method chosen.
• Comparing markups between businesses from different trade sectors can be misleading, as the normal markup rate differs from one industry to another.
• This ratio is calculated from figures for a single period and may not reflect current cost or price conditions after the financial statements are prepared.
