Hey,

As the recent changes in stock valuation and predictive cost reports are now taking into account (expected) losses, I was wondering which way of cost calculation is used in the margin by customer type report.

Thanks for the question, Gijs.

The margin reports are based on the sale price versus the **cost to produce**. This is the actual cost associated with the packaging of that beer, as per the process explained in:

[https://community.breww.com/t/how-are-batch-costings-and-wip-value-calculated-in-breww/852](https://community.breww.com/t/how-are-batch-costings-and-wip-value-calculated-in-breww/852)

The changes to the valuation report (and the fact that it can use a different calculation) is because there is a difference between **the cost of something** and **the value of something**. I hope that makes sense but please let us know if there are any questions on this.
