landed cost means Product Price + Extra Price (customs, duties, taxes, insurance,..) and from this calculation we can see the actual stock valuation of product.
Lets teke example for this :
I did 2 purchases of the same product with different landed costs:
Product cost per unit: 200
Landed costs: 400
Product cost per unit: 300
Landed costs: 200
Now I need to get the Average Cost price of the product + landed costs:
[(50 x 200 + 400) + (40 x 300 + 200)] / (50 + 40)
10,400 + 12,200 / 90 = 251.111
