You made 10 products. Only 9 are good enough to sell. What happened to the cost of number 10?
It did not disappear.
That product may become a test piece. It may go in the trash. It may be a production mistake or simply something that does not meet the standard you are willing to put your name on.
Throwing it away protects the quality of the inventory. It does not erase the materials or labor already consumed.
Sellable yield is the number that actually reaches inventory
If every unit you begin becomes a sellable product, the math is simple.
Real production is not always that clean.
Fabric gets cut wrong. Glaze fails. A print misfires. A candle develops a problem. A seam is unacceptable. A batch gets damaged. A prototype teaches you what not to do.
If those failures happen as a normal part of production, the cost of the successful products needs to reflect the fact that not everything you make becomes inventory you can sell.
A simple example
Imagine the materials and active labor for a production run total $100.
If that run produces 10 sellable items, the run carries $10 per sellable item before any other costs are added.
If the same $100 run produces only 8 items you are willing to sell, dividing the cost across all 10 items would pretend the two failed products still exist as good inventory.
They do not.
The $100 was real. The sellable yield was 8.
Do not solve the math by lowering your quality standard
The answer is not to sell something you know is substandard just because throwing it away hurts.
If the product does not meet your standard, do not pretend it does.
But also do not pretend the failed product was free.
We do not save the math by pretending that a bad product is good inventory.
Use the pattern to improve the business
Once you start tracking production loss, it can teach you something.
If the occasional failed piece is normal, it belongs in the cost picture. If the failure rate is consistently high, the deeper issue may be the process, equipment, material, design, training, or production method.
Pricing should not become an excuse to ignore inefficiency. Good cost information helps you see where the inefficiency lives.
This is one reason material cost alone can be misleading
A maker may say, “There is only $8 of material in this product.” But that number often assumes every piece of material produces a perfect sellable item.
Episode 5 of Festival Geeks expands the calculation to include replacement cost, sellable yield, consumables, equipment allowances, utilities, packaging, and active production labor.
That is how an apparent material cost becomes a more useful estimate of what one sellable item actually costs to make.
