Why Margins Matter More Than Markups in 2024

Here's a question that trips up more jewelers than you'd expect: if you buy a piece for $400 and sell it for $1,000, what's your margin? If you said 60%, you're thinking in markup terms — and that distinction matters more than most people realize.

Your margin on that sale is actually 60% ($600 profit ÷ $1,000 selling price). But a 2.5x markup gives you a 60% margin, not a 250% margin. The confusion between these two numbers leads to real pricing mistakes, especially when comparing performance across different product categories.

The reason margins matter more than markups for business decisions is simple: margins tell you what percentage of revenue is profit. Markups tell you how much you added to cost. When you're looking at your P&L, planning inventory buys, or comparing product category performance, margin is the number that actually predicts profitability.

Consider two product categories: bridal (average markup 1.8x, margin 44%) and fashion silver (average markup 3.0x, margin 67%). By markup alone, silver looks like the better business. But bridal generates $2,200 average revenue per transaction vs. $180 for silver. Dollar margin per sale: $968 for bridal vs. $120 for silver.

The lesson isn't that margin percentage is everything — it's that you need to think in margin percentage AND margin dollars AND turn rate to make good decisions. A 67% margin on a product that sits in your case for 8 months is worse than a 44% margin on a product that sells in 6 weeks.

Start tracking these three numbers for every product category: gross margin percentage, average margin dollars per sale, and sell-through rate (units sold ÷ units received per period). Together, they give you a complete picture that markup alone never will.
