Gross profit formula: How to calculate and improve profit margins

Understanding gross profit is essential for every business—regardless of industry, size, or structure. It’s one of the most important metrics for measuring profitability and operational efficiency. Yet, many businesses overlook the impact of small decisions on gross profit margins, or worse, calculate them incorrectly.
In this article, we’ll break down the gross profit formula, show you how to use it, and explore actionable ways to improve your profit margins over time.
What is gross profit?
Gross profit is the amount of revenue a company retains after subtracting the cost of goods sold (COGS). It tells you how efficiently a business is producing and delivering its products or services. Unlike net profit, gross profit doesn’t include indirect expenses like rent or admin costs—it focuses purely on production efficiency.
Gross profit formula explained
The gross profit formula is:
Gross Profit = Revenue – Cost of Goods Sold (COGS)
-
Revenue: The total sales earned from goods or services before expenses.
-
COGS: Direct costs tied to production—like raw materials, packaging, and direct labour.

What is gross profit margin?
Gross profit margin expresses gross profit as a percentage of total revenue:
Gross Profit Margin (%) = (Gross Profit / Revenue) x 100
It shows how much money you retain for every dollar of revenue after paying for production.
Why gross profit matters
How to calculate gross profit: A step-by-step example
Let’s say your business sells custom office furniture:
-
Revenue: $120,000
-
COGS: $72,000
Gross Profit = $120,000 – $72,000 = $48,000
Gross Profit Margin = ($48,000 / $120,000) x 100 = 40%
This means 40% of your revenue is available to cover overheads, reinvest in the business, or distribute as profit.
Common mistakes in calculating gross profit
-
Incorrect expense classification: Including admin costs or rent in COGS.
-
Missing hidden costs: Overlooking shipping, packaging, or production-related tools.
-
Overstating revenue: Failing to adjust for discounts, returns, or cancelled sales.
