Knowing your gross profit is crucial for understanding the financial health of your business. The gross profit calculation provides a clear picture of your profitability, helping you make informed decisions and drive growth. In this article, we’ll explore the gross profit formula, what constitutes COGS (Cost of Goods Sold), and industry benchmarks to determine a good gross profit margin.
Key Takeaways:
- Gross Profit Formula: <[ text{GPM} = frac{text{Revenue} - text{COGS}}{text{Revenue}} times 100 ]
- COGS includes only direct costs like materials, labor, and equipment; excludes indirect expenses like marketing or rent
- Average gross profit margin across all industries is 36.56%
- A good gross profit margin is typically 50-70%; above 70% is excellent, below 50% is undesirable
- For small businesses, a healthy net margin is around 10%
Understanding the Gross Profit Formula
The core formula for gross profit is:
<[ text{GPM} = frac{text{Revenue} - text{COGS}}{text{Revenue}} times 100 ]
This calculates the gross profit margin (GPM) as a percentage. For example, if a bike is sold for £300 with £120 in COGS, the gross profit would be £180, yielding a 60% gross profit margin (£180 / £300 × 100).
What Constitutes COGS?
COGS covers only the direct costs associated with producing a product or delivering a service, such as raw materials, direct labor, manufacturing supplies and equipment, and shipping. It excludes operating expenses like salaries, rent, and marketing. For service-based businesses, COGS would include direct labor and materials.

Manufacturers average 35% gross profit margin, while the clothing industry averages 48%. A good gross profit margin is generally considered to be 50-70%, with anything above 70% being excellent and below 50% being undesirable.
What is a Good Gross Profit Margin?
The concept of a good gross profit margin can vary depending on the industry. A 50-70% gross profit margin is generally considered good, with anything above 70% being very good and below 50% being undesirable. However, in some sectors, a 30-35% gross profit margin can be a common benchmark.
For small businesses, a gross profit calculator can be a helpful tool. As a general guideline:
- Under 5% net profit is considered low
- 10% net profit is considered healthy
- 20% net profit is considered strong
