CookingCost
The Ingredient I Never Bothered to Think About
For the first year or so of selling banana bread and cookies at my local market, I priced everything based on flour, sugar, and butter costs. Eggs? I basically treated them as free. They were just... eggs. A dozen for a few bucks, crack a couple into the bowl, move on with my life.
Then I built CookingCost because I was tired of guessing whether my baked goods were actually making me money, and when I started plugging in real numbers, eggs kept showing up as a bigger cost than I expected. Not huge on their own, but they added up fast, especially once egg prices started swinging all over the place at the grocery store. I'd budgeted for $3 a dozen and suddenly I was paying $6, sometimes more. That's not a rounding error when you're baking in volume.
Why Eggs Are Sneakier Than They Look
Here's the thing about eggs that I didn't appreciate until I really sat down and did the math: they're not just an ingredient, they're doing several jobs at once. They bind, they leaven, they add moisture, they add richness. Because they're doing so much work, most recipes lean on them heavily, and cottage bakers especially tend to use a lot of eggs in cakes, custards, brioche, and rich cookie doughs.
And unlike flour or sugar, egg prices are volatile. I've watched a dozen eggs jump from $2.50 to $7 in the same season because of supply issues. If you're pricing your baked goods once and never revisiting it, you could be losing money every single time you bake without even realizing it.
The Math I Was Getting Wrong
I used to just estimate eggs as "a few cents each" and call it a day. But when eggs are expensive, that few cents turns into 25 or 30 cents per egg pretty easily. If your recipe uses four eggs, that's over a dollar just in eggs for one batch, before you've even accounted for butter, sugar, flour, your time, or packaging.
I started tracking my egg cost per unit the same way I track everything else now — cost per egg, multiplied by how many eggs per recipe, divided by how many servings that recipe makes. It sounds tedious, but it took me maybe two minutes per recipe once I got the hang of it, and it completely changed how I priced my brioche rolls, which use way more eggs than people assume.
Buying Eggs Smarter (Without Cutting Corners)
I'm not going to tell you to switch to the cheapest eggs you can find, especially if you're already marketing your bakes as high quality or using pasture-raised eggs as part of your brand. But there are a few things that genuinely helped me control costs without sacrificing what makes my baking good.
- Buy in bulk when prices dip. Eggs freeze surprisingly well if you whisk them first and portion them into ice cube trays. I started doing this during a low-price stretch and it saved me from panic-buying during a spike a few months later.
- Track the price every time you buy, not just once. I got lazy about this for a while and just assumed my old cost was still accurate. It wasn't, and it meant I was underpricing a whole line of items for weeks.
- Compare cost per egg, not cost per dozen. Different stores package eggs differently, and it's easy to get tricked by a lower sticker price that's actually a worse deal per egg.
- Reconsider recipes that are egg-heavy if margins are tight. This doesn't mean gutting your recipe, but knowing which of your products are naturally more expensive to make helps you price them appropriately instead of guessing.
Why This Matters More If You're Running a Cottage Business
If you're just baking for fun, none of this really matters. Bake what makes you happy and don't worry about the spreadsheet. But if you're selling at farmers markets, taking custom orders, or running any kind of cottage food business, ingredient costs are your business. I learned this the hard way when I realized my "profitable" custard tarts were barely breaking even once I actually accounted for real egg prices instead of the number I'd guessed a year earlier.
Eggs are one of those ingredients that feel small on their own but quietly shape your whole cost structure because they show up in so many recipes. Cookies, cakes, breads, custards, quiches — they're everywhere in a baker's repertoire, which means a shift in egg prices doesn't just affect one product, it ripples through your entire menu.
What I Do Differently Now
These days, I check my egg cost every time I restock, not just when I remember to. I weigh my eggs for recipes where precision actually matters, like macarons or angel food cake, where egg white measurements can make or break the bake. And I stopped assuming eggs are a "cheap" ingredient just because they used to be.
Honestly, eggs taught me more about real cost tracking than almost any other ingredient, mostly because I underestimated them for so long. If you haven't looked closely at what eggs are actually costing you per batch, it's worth ten minutes with a calculator or a tool like CookingCost. You might be surprised at what you find, the same way I was.
