How It Works Under the Hood
Applies standard unit-economics identities in real time: Gross Margin = (Effective Price - COGS) / Effective Price, Markup = (Effective Price - COGS) / COGS, Break-Even Units = Ceil(Fixed Overhead / Unit Profit), and Target Price = COGS / (1 - Target Margin).

Enter Unit Cost (COGS), List Selling Price, and optional Promo Discount %.

Local Browser Processing & Privacy
Traditional web converters upload your documents, snippets, or media files to remote servers. Profit Margin, Markup & Discount Calculator runs inside your browser tab:
Your input text and files are processed locally without uploading payloads to a processing server.
Microdeck does not log or store the files or inputs you paste into tool workspaces (normal static hosting/CDN requests still load page assets).
Working outputs stay in your browser tab and are released when you reset the tool or close the tab.
Frequently Asked Questions
What is the difference between Profit Margin and Markup?
Gross Margin is profit divided by selling price (never exceeds 100%), while Markup is profit divided by product cost. A product costing $25 sold for $50 has a 50% margin but a 100% markup.
Why avoid hardcoding specific marketplace fees in this calculator?
Platform commissions and shipping subsidies vary by category, region, and quarter. Keeping pure cost, price, and discount math ensures reliable calculations in every market.
