About Profit Margin Calculator

Profit Margin Calculator analyses cost and selling price to show profit, margin percentage, and markup, with optional expenses, tax, and discount fields. Founders searching "profit margin calculator", "gross margin", and "markup vs margin" need these distinctions before changing prices.

Enter cost per unit and selling price. Optionally include other expenses, tax rate, and discount. Margin is profit relative to price; markup is profit relative to cost - mixing them up causes under-pricing.

Unit economics still ignore marketing CAC, returns, and overhead allocation unless you fold those into expenses. Use the tool for line-item clarity, then zoom out to full P&L reality.
