Use this free online Profit Margin Calculator to compute gross profit, margin percentage, and markup from cost and selling price. Use it for budgeting, pricing, forecasting, and comparison work where small input changes can materially affect the final decision. The form focuses on Revenue, Cost and returns Profit Inputs, Result, so you can move from input to answer without setting up a spreadsheet or custom script. Run one realistic example, adjust the inputs, and compare how the result changes before you copy or share it. The output is an estimate rather than financial advice, so confirm assumptions, taxes, fees, and policy details before making commitments.
