The invention provides a dynamic configurable automatic calculation method for indoor cost of project personnel, and relates to the field. The dynamic configurable automatic calculation method for the indoor cost of the project personnel aims at solving the problems that in the real estate evaluation industry, calculation of the indoor cost of the project personnel is low in efficiency, prone to errors and difficult to adapt to dynamic changes. According to the method, through the steps of defining project types, calculating starting and ending time, configuring differential calculation formulas, setting dynamic coefficients, collecting data, performing automatic batch calculation, presenting results and the like, automatic and precise calculation of the interior cost is realized. Parameters can be flexibly configured according to the requirements of different evaluation companies, dynamic adjustment in the project process is adapted, the calculation efficiency and accuracy are remarkably improved, and a management layer and employees can conveniently check related data in real time.
