Markup and margin are not the same thing. Here's the difference — and your numbers.
Or enter cost and desired margin/markup below:
Markup is profit as a percentage of COST. Margin is profit as a percentage of SELLING PRICE. A 50% markup on a $100 item = $150 selling price. A 50% margin on a $100 item = $200 selling price. They sound similar but produce very different results — confusing them is one of the most common small business pricing mistakes.
Pricing is just one piece. Managing cash flow, invoicing, and taxes matters just as much.
