The invention relates to the technical field of information, and provides an index calculation engine implementation method based on a multi-dimensional model. The method aims to solve the problems of different data index apertures, inaccurate data, data processing logic hard code stacking, repeated processing, batch running crossing dependence and long batch running operation time consumption. The main scheme comprises steps of constructing a multi-dimensional model table and a dimension table, and providing a data source for index calculation; according to the multi-dimensional model table, carrying out index calculation logic design, and obtaining a basic index engine configuration table, an addition and subtraction index engine configuration table and a multiplication and division index configuration table; calling the basic index engine configuration table, and calculating to obtain a basic index calculation result; calling an addition and subtraction index engine configuration table, and calculating to obtain an addition and subtraction index calculation result; and calling the multiplication and division index engine configuration table, and calculating the multiplication and division index engine configuration table to obtain a multiplication and division index calculation result; taking the obtained index calculation result as a data interface to provide services for the outside.
