The invention provides a software development efficiency obtaining method. The method comprises the steps of creating a tag at the beginning of software research and development, wherein the tag is used for recording a software research and development stage, and the software research and development stage at least includes a development stage and a test stage; when the software research and development stage is changed, modifying the tag, and recording a tag modification moment; according to the recorded modification moment, obtaining development time and test time of the software research and development, and according to the development time and the test time, obtaining a development time proportion, and taking the development time proportion as software development efficiency. According to the software development efficiency obtaining method provided by the invention, by automatically obtaining the development time and the test time, the development time proportion is obtained andserves as the software development efficiency, so that the automation level is high, the efficiency is high, labor is not required for manual statistics and calculation, the labor input is greatly reduced, the data accuracy is ensured, and accurate software development efficiency is obtained.
