What is yield loss and why does it matter for COGS?

Yield loss is the reduction in quantity or weight of raw materials during processing, such as moisture loss, trimming, or spoilage. If you start with 1,000 lbs of ingredients and yield 850 lbs of finished product, your true cost per unit is based on 1,000 lbs of input, not 850. Ignoring yield loss systematically understates COGS and overstates margins.

How do I calculate COGS for a food brand with multiple co-packers?

For each co-packer, you need to capture their per-unit conversion cost (toll fee), any yield loss they introduce, and any packaging materials they source on your behalf. True COGS per SKU = raw material cost (adjusted for yield) + co-packer conversion fee + packaging + inbound freight + allocated overhead. The challenge is that co-packers rarely give you lot-level yield data automatically, you have to build that into your production reporting workflow.

What is the difference between standard cost and actual cost for CPG brands?

Standard cost is a predetermined estimate of what a unit should cost based on expected ingredient prices and yields. Actual cost is what you really paid, adjusted for real yield and real purchase prices. The gap between them is called a cost variance. Most early-stage food brands run on standard costs in spreadsheets and only discover variances at month-end, which is too late to act on them.

How often should a CPG brand update its COGS calculations?

Ideally, COGS should update continuously as purchase orders are received and production batches are completed. At minimum, recalculate COGS whenever a supplier price changes, a new production run completes, or a new lot of ingredients is received. Waiting until month-end means you are making pricing and purchasing decisions on stale data.

What hidden costs do food brands most often miss in COGS?

The most commonly missed costs are: yield loss (especially moisture loss in baking and trimming in produce), inbound freight and broker fees on ingredients, co-packer setup and changeover fees, rework and repack labor, and quality testing costs. Organic brands also frequently miss the cost of maintaining mass balance documentation, which has real labor overhead.

The Complete Guide to CPG COGS (Cost of Goods Sold)

Why COGS is the Most Misunderstood Metric in CPG

For most software companies, Cost of Goods Sold (COGS) is simple: hosting fees and customer support. For a food and beverage brand, COGS is a living, breathing, constantly shifting number. It includes raw ingredients, packaging, co-packer tolling fees, inbound freight, spoilage, yield loss, and overhead allocation.

When a food brand gets COGS wrong, they price their products incorrectly. They run promotions that actually lose money. They raise capital based on false margin assumptions. This guide breaks down exactly how to calculate true landed COGS and how to track it as you scale.

The True Landed Cost Formula

Most early-stage brands calculate COGS by adding up their Bill of Materials (BOM). This is a critical mistake. The BOM only tells you what the product should cost in a perfect world. True landed cost tells you what it actually cost to get that product onto a warehouse shelf ready to sell.

True Landed Cost =

+ Raw Materials (Ingredients)
+ Packaging (Primary, secondary, and tertiary)
+ Inbound Freight (Shipping ingredients to the co-packer)
+ Tolling Fees (What the co-packer charges for labor/overhead)
+ Yield Loss & Spoilage (Ingredients wasted during production)
+ Transfer Freight (Shipping finished goods from co-packer to 3PL)

The Silent Margin Killers: Yield Variance and Freight

If your theoretical margin is 45% but your actual cash margin at month-end is 38%, where did the 7% go? In almost every case, it vanishes into two buckets: yield variance and unallocated freight.

1. Yield Variance

You send 1,000 lbs of ingredients to a co-packer. The recipe says that should produce 10,000 units. But the co-packer only yields 9,200 units. Some ingredient stuck to the vats, some spilled, some units failed QA. If you divide your ingredient cost by 10,000, your COGS is wrong. You must divide the total ingredient cost by the actual yield of 9,200 units.

2. Unallocated Inbound Freight

You buy $5,000 of glass bottles. Shipping those bottles to the co-packer costs $800. Many brands log the $800 as a general "shipping expense" on their P&L. It isn't. It is a direct cost of producing the product. If you don't allocate that $800 to the cost of the bottles, your SKU profitability metrics will lie to you.

Moving from Spreadsheets to Real-Time COGS

Calculating landed cost for one production run in Excel takes a few hours. Calculating it for 15 SKUs across 3 co-packers with fluctuating ingredient prices and weekly production runs is mathematically impossible to do manually without errors.

This is why food brands eventually adopt operations software. A system like Guidance automatically absorbs purchase orders, freight bills, and co-packer yield reports, calculating true landed COGS down to the penny for every single batch produced.
