The Gross Margin Formula

The formula for calculating gross margin is straightforward:

Gross Margin = ((Net Sales - Cost of Goods Sold) / Net Sales) x 100

  • Net Sales: Total revenue from sales, minus any discounts or returns.
  • Cost of Goods Sold (COGS): Direct costs associated with producing goods or services, including materials and labor.

Step-by-Step Calculation

  1. Determine Net Sales: Calculate the total revenue from your sales, subtracting any discounts or allowances.
  2. Calculate COGS: Determine the direct costs involved in producing or acquiring the goods or services you sell.
  3. Apply the Formula: Subtract COGS from Net Sales, divide the result by Net Sales, and multiply by 100 to get the gross margin percentage.

For example, if a business has net sales of $200,000 and a COGS of $80,000, the gross margin would be:

((200,000 - 80,000) / 200,000) x 100 = 60%

Gross Margin vs. Net Margin

It's important to distinguish between gross margin and net margin. Gross margin focuses solely on the relationship between revenue and COGS. Net margin, on the other hand, considers all expenses, including operating expenses, interest, and taxes, providing a broader picture of overall profitability.
