Understanding Margin vs Markup

Many business owners confuse margin and markup, leading to pricing mistakes that can cost thousands in lost profit. Here's what you need to know:

Gross Margin Formula

Gross Margin % = (Selling Price - Cost) ÷ Selling Price × 100

This tells you what percentage of each sale is profit. A 40% margin means you keep 40 cents of every dollar.

Markup Formula

Markup % = (Selling Price - Cost) ÷ Cost × 100

This tells you how much you're adding on top of cost. A 100% markup means you're doubling your cost price.

Why This Matters

If your supplier says "we need a 50% markup," you might think that gives you a 50% margin. It doesn't! A 50% markup only gives you a 33.3% margin. Understanding this difference is crucial for profitable pricing.

Common Pricing Scenarios

Cost Markup % Price Margin %
$50 100% $100 50%
$50 50% $75 33.3%
$50 200% $150 66.7%
