Margin Calculator

A free margin calculator built around the distinction that trips up most pricing conversations: margin is profit divided by the selling price, markup is profit divided by the cost, and the same sale produces two different percentages. It computes both from any cost-and-price pair, and two more views solve the price — either from a markup you apply to cost or from a gross margin you want to achieve. All three views are plain arithmetic computed in your browser on the numbers you enter — a pricing worksheet, not tax, pricing, or accounting advice.
