Accounting Gross Profit Margin Calculator
Calculate gross profit, total cost of goods sold, and gross profit margin from your sales revenue and direct costs.
Overview
This accounting gross profit margin calculator estimates the proportion of sales revenue left after direct costs are deducted. Enter your sales revenue along with materials or inventory, direct labor, and other costs directly related to producing or delivering what you sold.
How it works
The calculator adds materials or inventory costs, direct labor, and other direct costs to calculate cost of goods sold. It subtracts this total from sales revenue to find gross profit. Gross profit margin is then calculated by dividing gross profit by sales revenue and multiplying by 100. A higher margin generally means more revenue remains to cover indirect expenses and profit, but useful comparisons should use consistent cost classifications and accounting periods.
