Average Unit Cost Calculation

(0) ShareShare
ReportReport
Posted on by

Dear All,

How does the BC calculate the average unit cost of a inventory item?

In the Item card, when we go to Unit Cost. It will reflect the average unit cost. When we click in, we can see a list of cost movement.

based on the above, how does the system calculate the Average cost and shown in the closing entry?

on 27 March, we make a purchase with a lower purchase price, and it bring down the average cost to be 941.77.

in 9 April, we make a sell. However the system picked the unit cost 980.79 as the cost for this sales order. Why system does not use 941.77? How does the system decide which cost to use?

starting from this entry, the average cost all went wrong

How do we correct this issues?

we can see on 29 June, the closing quantity is 0, but we have a cost amount of - 785.28

I have the same question (0)

    Hi,

    You need to run report Adjust cost - Item entries and then this will be adjusted correctly.

    Hello,

    Below is a Average Cost Overview webinar I did awhile back. Hope this helps explain Average Cost, in addition to running your Adjust Cost and Item Entries. If this is not running daily, because it is not set to true on the Inventory Setup, I would create a Job Queue to run nightly.

    Dear Steve,

    thank for your kind assistant.

    Refer to the above inventory setup, can help to verify this is correctly setup?

    I had run the Cost Adjust - Item Entries, and the average cost is now correct. (including previous entries)

    The automatic cost adjustment was set to always. i was wondering what could go wrong that causes the average cost price that is less correct.
