국민·퇴직·개인·주택연금 소득대체율 추정과 노후소득보장체계 충당방안

As the aging is rapidly growing, there is an increasing interest in the adequate retirement income in order to enjoy a life of old age. According to the results of this study, the adequate replacement rate was 76.4%(95.6% of middle class consumption), and looking at this by income level, 163.5%(214.9%) of the low income class, 67.2%(80.8%) of the middle income class and 28.7% of the high income class(34.9%) were estimated respectively. On the other hand, the actual replacement rate was 27.2%(54.4% for low income class, 30.5% for middle income class and 21.5% for high income class, respectively). It is analyzed that the lower the income level, the weaker the sufficiency(judged by the difference between the adequate and the actual replacement rate). In the sensitivity analysis that takes into account the maturity stage of the pension system in the future, it seems that the guarantee of the old age income is strengthened mainly in the middle class and the high income class. It means that there needs to be a separate pension policy for bellow the middle class. Therefore, this paper suggests that the following policies need to be enforced: differentiated pension policies for each income level, a preferential pension policy for those who are not adequately prepared for retirement(eg, baby boomers, 50 generations), lifetime annuitization, and a system to convert retirement assets into annuities.
