Gross Profit Formula

Gross profit is equal to net sales less costs of goods sold. Net sales is a company's sales revenue less any allowances for sales returns. Cost of goods sold is the cost of inventory sold, including both fixed costs and variable costs. Fixed costs are static and don't tend to change based on production. For example, facility rent, utilities and facility manager salaries tend to be fixed costs. Variable costs are the costs that change based on how much you're producing. Manufacturing labor, supplies, packaging and shipping costs are all variable.

Gross Margin Ratio

From gross profit, managers can calculate useful ratios that can help them understand profitability. The most common variation on gross profit is gross margin. Gross margin represents what amount of every sale is converted to gross profit. Gross margin is calculated by dividing gross profit by net sales for the period. For example, say net sales were $500,000 and cost of goods sold was $100,000. Gross profit is $400,000 and gross margin equals 80 percent.

Gross Profit Method

Gross profit is often used to estimate cost of goods sold and inventory in between reporting periods. It's useful when management needs to estimate inventory levels but can't perform a physical count. To calculate cost of

goods sold using the gross profit method, multiply the cost of goods available for sale by one, minus the gross margin ratio. Cost of goods available for sale is beginning inventory plus purchases. For example, suppose a business has a gross margin of 60 percent, has a beginning inventory of $300,000, and has purchased $100,000 in inventory materials this period. The estimated cost of goods sold is 40 percent multiplied by $400,000, or $160,000. The difference between cost of goods available for sale and cost of goods sold is current inventory. In this case, it's $240,000.

Inventory Choices and Gross Margin

The way a company chooses to value its inventory affects its gross profit calculation. Managers can choose to use "last in, first out" (LIFO), "first in, first out" (FIFO), or average cost to calculate cost of goods sold. LIFO assumes that the most recent inventory purchases are the ones sold first. In contrast, FIFO assumes the oldest inventory is what's sold. Average cost calculates cost of goods sold using the overall average inventory costs. Depending on a manager's choice, gross profit can vary wildly. For example, suppose a company's oldest inventory cost $200, the newest cost $400, and it has sold one unit for $1,000. Gross profit would be calculated as $800 under LIFO and $600 under FIFO.
