What is Gross Margin?

Let's use a real example: a chocolate layer cake. You sell it for $45. The ingredients — flour, cocoa, eggs, butter, sugar, cream cheese frosting — cost you $11.25. Your gross margin is 75%, meaning $33.75 of that $45 goes toward everything else: your labor, packaging, boxes, delivery, rent, and profit. That 75% has to cover a lot. If your gross margin drops to 60% because you switched to a more expensive cocoa supplier, you're now only keeping $27 per cake instead of $33.75. Over 40 cakes a month, that's $270 you've lost. Gross margin is different from profit. Profit is what's left after every expense. Gross margin is just the ingredient math. You need a healthy gross margin to survive. Most bakeries aim for 65–75% gross margin on custom cakes and 70–80% on retail items like bread and cookies. If you're under 60%, you're likely underpriced or your ingredient costs are too high. You calculate gross margin the same way for every product. A box of six cupcakes sells for $24. Ingredients cost $6. Gross margin: (24 − 6) / 24 = 75%. A sourdough loaf sells for $8. Ingredients cost $1.40. Gross margin: (8 − 1.40) / 8 = 82.5%. The higher the percentage, the more breathing room you have. Tracking gross margin per product matters because some items are more profitable than others. Your wedding cakes might have a 72% margin. Your cookies might be 78%. Your custom fondant work might be 65% because it's labor-heavy. When you know these numbers, you can decide which products to push and which ones to price higher or stop making altogether.
