Abstract: Method and apparatus for forecasting a characteristic information change. Historical characteristic data in at least one computation period and current incremental data of multiple pieces of first characteristic information corresponding to a pre-estimation model is acquired. The current incremental data is used for indicating a ratio of characteristic data on a day immediately before a forecasting day of each of the multiple pieces to the historical characteristic data in the at least one computation period of each of the multiple pieces of first characteristic information. A first change information on the forecasting day of second characteristic information is determined by a forecasting process using the pre-estimation model based on the historical characteristic data and the current incremental data. Based on the first change information, change pre-estimation information on the forecasting day of the second characteristic information is determined to prompt a user to execute a corresponding operation.
