Markup vs margin calculator
Markup and margin are easy to mix up, and getting them wrong can quietly wreck your pricing. This tool keeps them straight: enter any combination of cost, selling price, markup % or margin %, and it returns all four plus your profit in one place.
Use it to set prices from a target margin, check the real margin behind a markup, or sanity-check a supplier quote.
