Net sales and gross profit are not the same figure. Net sales is the revenue a business keeps after subtracting customer returns, allowances, and discounts from gross sales. Gross profit goes one step further and subtracts the direct cost of producing or acquiring the goods that were sold. Because gross profit starts from net sales and then deducts more, net sales is always the larger number unless the cost of goods sold happens to be zero. The two live on the same income statement, and one feeds into the other, but they answer different questions about a business.
How Each Number Is Calculated
Net sales begins with gross sales, the total dollar amount of all transactions before any adjustments. From that figure, you subtract three categories:
- Returns — refunds issued when customers send products back.
- Allowances — price reductions granted for damaged or defective goods the customer keeps.
- Discounts — reductions offered for early payment or volume purchases.
The formula is Net Sales = Gross Sales − Returns − Allowances − Discounts. Sales tax collected from customers is generally excluded, because that money passes through to the taxing authority rather than becoming revenue.
Gross profit takes the next step: Gross Profit = Net Sales − Cost of Goods Sold (COGS). COGS captures only the expenses directly tied to producing or acquiring what was sold. For a manufacturer, that means raw materials, direct labor for employees who work on the product itself, and manufacturing overhead such as factory rent, utilities, equipment depreciation, and inbound freight. For a retailer or wholesaler, COGS is simpler: the purchase price of inventory plus the cost of shipping it in.
Expenses that keep the business running but are not tied to a specific product stay out of COGS. Advertising, office rent, administrative salaries, insurance, and loan interest are operating expenses, and they come out of gross profit later on the income statement to arrive at operating income and then net income.
On a sole proprietor’s Schedule C (Form 1040), Line 1 records gross receipts and Line 2 records returns and allowances; the difference on Line 3 is effectively net sales. COGS is calculated in Part III and carried to Line 4, and Line 5 shows gross profit.1Internal Revenue Service. 2025 Schedule C (Form 1040)2Internal Revenue Service. 2025 Instructions for Schedule C (Form 1040) Corporations and partnerships use Form 1125-A, which breaks COGS into purchases, cost of labor, additional capitalized costs under Section 263A, and other costs.3Internal Revenue Service. Form 1125-A Cost of Goods Sold
A Side-by-Side Example
Put both formulas to work on the same set of numbers. Suppose a small furniture company reports the following for the year:
- Gross sales: $800,000
- Returns: $20,000
- Allowances: $5,000
- Discounts: $15,000
- Cost of goods sold: $400,000
Net sales works out to $800,000 − $20,000 − $5,000 − $15,000 = $760,000. Gross profit is $760,000 − $400,000 = $360,000. Net sales answers the question “how much did customers actually pay us?” Gross profit answers “how much did we keep after covering the cost of the products themselves?”
What Each Number Tells You
Although both figures sit on the same income statement, they measure different things and interest different people.
- What they deduct. Net sales removes transaction-level adjustments. Gross profit removes the direct cost of producing or buying the goods.
- What they reveal. Net sales reflects market demand and the effectiveness of pricing and sales strategy. Gross profit reflects how efficiently a business produces or sources its products relative to what it charges.
- Who watches which. Sales and marketing teams follow net sales to gauge revenue trends. Operations managers and investors focus on gross profit to judge production efficiency and pricing power.
The two can move in opposite directions. A business can post rising net sales and falling gross profit at the same time if raw material costs spike while prices stay flat. It can also shrink net sales but grow gross profit by trimming production costs or dropping low-margin product lines.
Gross Profit Margin
Investors rarely compare gross profit in raw dollars. They convert it into a percentage: (Gross Profit ÷ Net Sales) × 100. The furniture company above has a gross profit margin of roughly 47.4 percent ($360,000 ÷ $760,000).
Expressed as a ratio, the number makes companies of very different sizes comparable within the same industry. A business with $5 million in net sales and a 45 percent margin may run a tighter operation than a competitor doing $20 million in net sales at a 30 percent margin. Watching the margin over time also signals whether production costs are climbing faster than prices.
How Service Businesses Fit In
The framework above assumes physical products. Service businesses often work differently. A consulting firm, law practice, or accounting firm typically has no inventory and no traditional COGS. The wages of the people delivering the service usually appear as operating expenses instead.
Some service companies do track a version of COGS, often labeled “cost of services” or “cost of revenue.” This is common when materials are part of the job, such as an HVAC contractor buying a compressor for a customer’s repair. The compressor cost and the technician’s wages for that job get treated like COGS, and the resulting figure functions like gross profit.
For tax reporting, the IRS distinguishes between businesses that must account for inventory and those that do not. Under the gross receipts test, a business with average annual gross receipts of $32 million or less (the 2026 inflation-adjusted threshold) can generally use the cash method and may not need to track inventory for tax purposes.4Internal Revenue Service. Revenue Procedure 2025-32 – 2026 Adjusted Items Many small service businesses fall well under that ceiling.
Where the Two Figures Appear on an Income Statement
Both numbers show up on the income statement, but only when the company uses a multi-step format. That format walks down the page in a set order:
- Gross sales
- Less returns, allowances, and discounts
- Net sales
- Less cost of goods sold
- Gross profit
- Less operating expenses
- Operating income
- Less or plus non-operating items such as interest and taxes
- Net income
A single-step income statement lumps all revenues together and all expenses together, then subtracts one from the other to reach net income, without breaking out gross profit as its own line. Small private companies sometimes use this simpler layout. Public companies filing an annual report on Form 10-K with the SEC use the multi-step structure, and SEC rules require the financial statements to present net revenue and cost of revenue so that gross profit is clearly identifiable.5SEC.gov.

If your own books show only a single bottom line, adding the intermediate steps is worth the effort. Net sales and gross profit each answer a real question about the business, and losing either one to a lumped total means losing the ability to see where a change in the bottom line actually came from.
