The embodiment of the invention relates to the field of computer data statistics, and particularly relates to a data statistical method and device. The data statistical method comprises the following steps of: firstly, according to a pre-set filtering rule, filtering original transaction data to obtain first transaction data, then, according to keyword information in the first transaction data, determining a calculation server corresponding to the first transaction data, and finally, sending the first transaction data to the calculation server, so that the calculation server sends second transaction data, which is obtained by performing statistics on the first transaction data according to a pre-set statistical dimension, to a query server to use. Visibly, the first transaction data having the same keywords can be sent to the same calculation server; the calculation server can send the second transaction data to the query server to use; therefore, the calculation statistical capability can be horizontally scaled in a manner of increasing the number of the calculation servers; the speed, at which data is written in a database, can be increased; and thus, the data query efficiency can be increased.
