What is Overhead Allocation?

Your ingredient costs are easy to track. A chocolate layer cake uses $3.40 in flour, cocoa, eggs, butter, and sugar. You can weigh it, measure it, cost it in 90 seconds. But you also pay $2,400 in rent every month, whether you bake 10 cakes or 100. You pay $180 for utilities, $120 for business insurance, $200 for packaging supplies, and $400 in equipment maintenance and replacement. That's $2,900 in overhead costs that have to be recovered somehow—and the only way to recover them is to spread them across every cake, loaf, and dozen cupcakes that leave your kitchen. Here's why this matters: if you bake 200 cakes per month and your overhead is $2,900, you're allocating $14.50 of overhead to each cake. Your $3.40 ingredient cost just became a $17.90 true cost per cake. If you're selling that cake for $25, your actual margin is only $7.10—not the $21.60 you thought. Miss this math and you'll spend three years wondering why a "profitable" product is slowly draining your bank account. Overhead allocation also reveals which products are actually carrying the weight of your business. A simple vanilla cupcake might have $0.80 in ingredients and $1.45 in allocated overhead, making your true cost $2.25. If you're selling it for $3.50, you're only netting $1.25 per cupcake. But a custom 3-tier fondant wedding cake with $8.20 in ingredients and $14.50 in allocated overhead has a true cost of $22.70. Selling it for $95 gives you a $72.30 margin. The wedding cakes are carrying your business. The cupcakes are filler. The allocation method matters too. Some bakers spread overhead equally across every product (simple, but inaccurate). Others allocate based on labor hours, ingredient cost, or production time. A bread bakery might allocate overhead based on oven hours used. A custom cake studio might allocate based on design time. The method you choose depends on what actually drives your costs.
