1. The specific calculation formula of floor land price is: floor land price = total land price/total building area, where total building area = total land area * plot ratio.

2. It can also be understood that floor land price refers to the average land price shared by the unit construction area, which can be simply understood as the land cost included in the unit selling price after a house is built on the land. Floor land price most truly reflects the unit land cost price contained in the unit price of building.

the calculation formula of floor premium is as follows: floor premium = land price/planned construction area = land unit price/plot ratio

Remarks: planned construction area = land area × plot ratio.
