Calculate gross profit margin, markup percentage, and gross profit. Free online margin calculator for businesses.
A margin calculator helps you determine the profit margin on your products or services, which is one of the most important metrics for any business. Profit margin shows what percentage of your revenue remains as profit after accounting for the cost of goods sold. Understanding your margins is essential for pricing decisions, profitability analysis, and business planning.
There are two key margin types: gross margin (revenue minus cost of goods sold) and net margin (revenue minus all expenses). Gross margin tells you how efficiently you produce and sell your products, while net margin reveals your overall profitability. Many business owners confuse margin with markup — while related, they're calculated differently and produce different percentages.
You buy a product for $45 and sell it for $75. Gross profit = $75 - $45 = $30. Margin = $30/$75 × 100 = 40%. Markup = $30/$45 × 100 = 66.67%. To achieve a 50% margin on a $45 cost: Selling Price = $45 / (1 - 0.50) = $90.
