How Processing Loss Is Calculated

Processing loss is the amount of material that cannot be accounted for after production, calculated automatically unless overridden. Understanding how this is calculated helps ensure your inventory and compliance records are accurate.

By default, processing loss is calculated as:

Processing Loss = Inputs – Outputs – Destruction

If no manual loss is entered, this formula is applied automatically.

Processing loss and Remaining value respect equivalent units inside a Work Order.

When a product has multiple inventory units, loss is calculated separately for each unit group and shown everywhere you’d expect—the Work Order summary & PDF, Batch event log, and Batch PDF.

This means that if you have an equivalent unit set up for a specific inventory item, the system will account for each equivalent unit when the processing loss or remaining value is calculated.

For example, if you expect your grams processing loss value to be 0, but instead you see 230ea in processing loss, this doesn’t mean you have 230g in processing loss. You're just seeing the difference between the input and output in the equivalent unit (ea). In this case, grams has a 0 loss bucket, and only eaches had a non-zero difference.
​
Let's see how it works now!

Let’s say we’re processing 1,000g of cannabis trim into pre-rolls.

Loss = 1,000g – 800g – 100g = 100g loss

📝 In this case, all inputs and outputs are in the same unit (g), so we have a single unit bucket. The loss is clearly calculated and shown in grams.
​

Now let’s say you're packaging 270g of pre-rolls into 108 units of packaged pre-rolls, 2.5g each.

When looking at a Work Order where you have inventory products with equivalent units, you'll need to be mindful of what your equivalency is for each of these products.
​
For this specific example, you have 2 products:

- A single “ea” is one package of five 0.5 g pre‑rolls, so 1 ea = 2.5 g.

- That means 1 g is roughly 0.4 ea because each 0.5 g pre‑roll is one‑fifth of the package.
​

- Pre-Rolls (Bulk) (0.5g) where display unit is "g" and ea = 0.5g
​

Loss Buckets:

📝 In this case, you might have expected no loss because your gram output balances your gram input, but you’ll still see a loss in the "ea" bucket because of the difference in equivalent units. This is normal behaviour when using unit equivalency.

Unit equivalency setup matters. If your units are not properly defined, the system won’t know how to relate them and might present skewed data in relation to what you were expecting to see.

✅ Always double-check the unit equivalency settings for each product to ensure accurate loss buckets and intuitive results.
