💰 Profit Margin Calculator

The Profit Margin Calculator is an essential financial utility for business owners, accountants, and entrepreneurs. It delivers the gross margin, gross profit, and cost-to-revenue ratio with a single click. Simply input your cost of goods sold (COGS) and the selling price (revenue). The calculator instantly reveals how much profit you retain per sale and the percentage margin — a vital indicator of business health. Unlike markup, margin reflects profitability relative to revenue, which is the standard for financial reporting. Whether you run a retail store, SaaS company, or freelance practice, this tool eliminates spreadsheet guesswork.

Gross margin is calculated as (Revenue – Cost) ÷ Revenue, displayed as a percentage. For example, a 40% margin means $0.40 of every dollar is profit. This calculator also shows the cost ratio, the complement of margin. Investors and lenders scrutinize this metric; now you can monitor it in real time. The tool is built with pure JavaScript, ensuring 100% data privacy — no information is transmitted to any server. It works offline, supports decimal precision, and is fully accessible. Use it to evaluate product lines, negotiate supplier pricing, or set profitable price points. Updated in 2025, the interface adapts seamlessly to any device, from smartwatch to 4K display.
