Valuing goods at a warehouse by average price presupposes that the sum of the
average price of a given item at the warehouse and its quantity is equal to the
burdened purchase value - that is, the cost you paid for this stock.
With every purchase, the average price is calculated (changes)
based on the following formula:

where
Value_of_purchase = purchase_price + purchase_costs
The average price at a warehouse is therefore burdened - it consists of
the supplier's price and the purchase costs (for example, transport, freight
forwarding, handling costs...).
Issues from the warehouse are made by average price. The value
of the issue is the product of the quantity and the average price. So if you
issue the entire quantity, the stock at the warehouse will always be equal to 0
(rounding errors notwithstanding).
Let's look at an example of an imaginary item you're purchasing from a foreigner

Analyzing the Table
The prices marked in red changed upon purchase (as we saw above, the average
price is only calculated for receipts, and is used for issued).
The average price does not only contain the purchase price (145 EUR), but
also costs, giving us a total of 150 EUR.
As you can see, despite the reduction of the price in the second purchase
from 100 to 85 GBP, the average price has not gone down.
Why? Because you still had a fairly large stock (40 pieces) of the previous
shipment, which cost you significantly more. If you were to calculate the price
difference, you'd have to take into account the mixture of higher and lower
prices - this is already accounted for in the formula for the average price.
Only after the last purchase did the average price approach the purchase
price. Why? Because the stock was finally small enough so as not to have such a
large impact on the valuation.

Average price:
- changes with each purchase
- is used
to value issues, which do not change the average price
- is increased by purchase costs
- is not
increased by a margin or tax (that is, is a net price)
- reveals the movement of stock (the less
stock moves, the greater the difference between the purchase and average
price)
- makes possible the calculation of the
correct average price difference regardles of the different purchases
prices of incoming items
