I’ve sat inside the financials of a dozen food brands over the past three years. And I keep finding the same thing buried in the spreadsheets: founders who believe they’re profitable because their product margins look healthy.

They’re not.

The Pattern

Here’s what it looks like every time.

A founder builds a food product. They calculate their cost of goods, set a retail price, and land somewhere around 40% margin. On paper, the business looks solid.

But the bank account tells a different story. Revenue is growing. Orders are shipping. And somehow, the business is still bleeding cash.

The reason is almost always the same: they’re calculating gross margin, not net margin. And the difference between those two numbers is where the money disappears.

Gross margin only accounts for ingredients and packaging. It answers one question: “How much does it cost to make this product?” That’s it. It doesn’t tell you whether the business makes money.

Net margin accounts for everything else. Co-packing fees. Blending setup charges. Equipment changeover costs between product runs. Shipping the raw materials to the co-packer. Warehousing. Freight to the customer. Platform fees. Rent. Insurance. Salaries. And the biggest invisible one: the founder’s own time, which never shows up on any spreadsheet.

Your spreadsheet shows gross margin. Your bank account shows net margin. When a founder tells me “we’re at 40%,” they’re almost always talking about gross. And that number, on its own, is a lie of omission.

The Founder Who Was “At 40%” and Losing Money

I was working with a growing food brand, reviewing their product line profitability. The founder had been running on gut instinct for years. It was a brilliant product developer. Incredible palate. Loyal customers.

Her spreadsheet said 40% margins across the board.

But when we mapped the actual cost path, product by product, here’s what we found.

The headline margin didn’t include blending costs. Didn’t include the setup fee the co-packer charges every production run. Didn’t include the changeover cleaning between products (which only applied to two of her six products, but was being averaged across all of them). Didn’t include the cost of shipping raw ingredients to the co-packer’s facility.

When we added it all up, her best-selling product was actually at 38%. Her specialty items were at 22% and 28%.

And none of those numbers included overhead. Rent. Insurance. Her salary. Marketing.

It said something I’ve now heard three times in the past year: “I have a pretty good sense of things. Something is not right. We’re losing more money than we should be.”

Her intuition was correct. The spreadsheet was lying.

The Reformulation That Changed Everything

A different brand, different product. This founder was watching her ingredient costs climb every quarter. One key raw material had nearly doubled in price over eighteen months. Her margins on that product had quietly dropped from the mid-30s to 17%.

It didn’t know it was 17% until we mapped it.

The fix wasn’t dramatic. We reformulated the product, reduced the package weight (while keeping the same number of servings), switched to a different grade of the same ingredient, and renegotiated the fill rate with her co-packer.

The result: margins went from 17% to 37%.

Not because of a new product. Not because of a price increase. Because someone finally sat down and mapped where every dollar was actually going, line by line, and found the three places where money was leaking.

The founder had been staring at the same product for two years. The problem wasn’t that it didn’t care. It was that her costing model didn’t show her where to look.

Why This Keeps Happening

Three reasons.

The costing model was built at startup scale and never upgraded. When you’re doing your first production run, “ingredients plus packaging divided by retail price” is good enough. But by the time you’re running six products across multiple co-packers with international ingredient sourcing, that formula is dangerously incomplete.

Nobody owns the full cost picture. The founder knows the product. The operations person knows the logistics. The bookkeeper knows the overhead. But nobody is mapping the complete cost path from raw ingredient to delivered product, including every fee, every setup charge, every hidden cost that sits between those two points.

The industry doesn’t teach this. Most food business courses teach you how to calculate COGS for a pitch deck. They don’t teach you how to build a costing model that tells you the truth once you’re actually running. The gap between “startup math” and “operating math” is where profitability goes to die.

What the Brands That Got It Right Did Differently

Every founder I’ve worked with who actually fixed this did the same three things.

1. They mapped the full cost path, not just COGS.

Every cost between “I have ingredients” and “the customer has the product.” Blending. Co-packing. Setup fees. Changeover fees. Freight to the co-packer. Freight to the warehouse. Freight to the customer. Platform commissions. Payment processing. Returns. Every single one, per product.

2. They stopped averaging.

A changeover fee that only applies to two of six products was being spread across all six. A setup charge that kicks in once per production run was being divided by annual volume instead of per-run volume. Averaging hides the products that are killing you.

3. They built a costing model that updates.

Not a one-time spreadsheet. A living document where ingredient costs, co-packer rates, and freight quotes get updated every quarter. Because the number that was true in January is a lie by June.

If you do those three things, you’ll know your real margin within a week. And I promise: at least one product on your line is not what you think it is.

The spreadsheet isn’t broken. It’s incomplete. And in a business where margins are everything, incomplete is the same as wrong.

Next week: the co-packer evaluation trap, and the one question that tells you whether your vendor is scaling with you or holding you back.

If this pattern sounds familiar, you’re not alone. I work with brands navigating exactly this. Reply and let’s compare notes.

Share this with the founder or operations lead you think would find this pattern familiar.

Quick hits from this week in operations and supply chain:

↑ Strait of Hormuz disruptions push oil past $100/barrel — If your freight costs “don’t make sense” this month, this is why. Diesel price ripple effects hit food logistics within 2-3 weeks.

👀 Blue Yonder expands agentic AI for supply chain execution — The gap between planning software and floor reality is where most implementations fail. AI won’t fix that gap. Process mapping will.

↑ CPG digital transformation: warehouse automation showing clearest ROI — The boring stuff works. Automated warehouse management, real-time production monitoring, and digital traceability are outperforming the flashy AI pilots.

↓ Global food prices surge 2.1% as geopolitical volatility disrupts supply — Fertilizer shocks, La Niña, Middle East disruptions. If your ingredient costs jumped this quarter, this is the macro picture. The brands that survive know their real margins.

👀 FAA launches eVTOL cargo delivery pilot program — Electric vertical takeoff aircraft for logistics. Eight pilot projects across the US. Still early, but worth watching if you ship perishables.

↑ 24 states sue to block Trump’s 10% global tariff — If you source ingredients internationally, this uncertainty is real. Map your exposure now, not when the ruling drops.
