The sense of gain is a comprehensive concept，including gain，cognition and evaluation. Sense of gain is the cornerstone of well-being and an important condition for shaping happiness. We define the compound subjective and objective socioeconomic status as the perceived socioeconomic status index （PSSI），this gain sense of socioeconomic status index is influenced by social psychological process，and sharp happiness. This paper explored the relationship between PSSI and life satisfaction by analysis of 2，628 adults data. We found that the PSSI could predict life satisfaction，and the higher PSSI，the higher people’s life satisfaction is perceived. The brothers and sisters condition，car-owning and age moderated the relationship between the gain sense of socioeconomic status and happiness. Appropriate socioeconomic status enhancement and group specificity should be considered when helping people to optimize their sense of gain.
