I am now thinking about differences of cost, price and value.
I can compare these terms to economics language.

Cost is a cost.
Price is a list price.
Value is the proceeds.

So this formula is made up.

[Price]=[Cost]×(1+[Profit Ratio])
[Value]=[Price]×(1-[Discount Ratio])

Value≈Price≥Cost
0≤Profit Ratio≤1
0≤Discount Ratio≤1

These two ratio are a correction changing in various situation.

Profit Ratio

Pawn=100%
Archbishop=37.5%~45.8%
Queen=12.5%~18.75%
Bishop-pairs=8.3%
