Item Cost Calculate in ERPNEXT

Hello,
I would like your suggestion for a solution for:

We want to automatically add cost our products as follows after we add them, and we want to use them from the costed amount in the quotation.

Here is our costs:
inland shipping cost: 10 USD * PRODUCT WEIGHT(KG)
other expenses: 5%
storage costs: 2 USD * PRODUCT WEIGHT (KG)

In other words, we want the price in the price list to be added with these costs in our offers quotations and reflected as the product unit price.
