Abstract

This study estimate the adequate replacement rate of retirement income by income brackets and suggests roles of pension and non-pension income sources to achieve it for each income bracket. Priori research focused on elderly poverty; however, there has been little discussion about an adequate income level for retirement. We calculate an adequate income replacement rate separately for the poor, middle, and high income group as well as the average level of replacement rate for all groups. We also investigate the gap between the adequate income replacement rates and realized rates, and propose roles for each income source to curtail the gap. It is essential to recognize that the adequate income for retirement is unable to be met only by an annuity. To emove the gap, it is vital to utilize non-pension income although annuity is a primary source for retirement. Especially, the public and private pension plays a role to overcome poverty and live affluent in retirement, respectively.

본 연구에서는 소득계층별로 노후에 필요한 소득대체율을 추정하고 이를 달성하기 위한 연금 및 비연금 소득원의 역할 분담을 논하고 있다. 그 동안 노후소득보장 수준을 논함에 있어 노후빈곤 문제에 초점을 두다 보니 노후의 필요소득 수준에 대한 논의는 상대적으로 적었다. 이러한 관점에서 동 연구에서는 노후생활을 위한 평균적인 필요소득대체율 뿐만 아니라(전체 51.3%), 소득계층별로 필요소득대체율을 산출하고 있다(빈곤층 177.6%, 중산층 68.1%, 고소득층 29.3%). 또한 소득계층별 필요소득대체율이 현실의 실현소득대체율과 얼마나 격차가 있는 지를 살펴보았으며, 이를 통해 소득원별 역할 분담이 필요하다는 시사점을 끌어내고 있다. 즉, 목표소득대체율을 달성하기 위해 현 노인세대의 경우 연금으로만 충당하기 어려우므로 비연금 소득원을 적극 활용할 필요가 있음을 제시하였다. 한편 미래의 노인세대(현 근로세대)는 무엇보다 연금소득 마련이 중요할 것이라는 점에서 공적연금을 통한 탈빈곤, 사적연금을 통한 중산층 이상의 삶을 마련할 수 있도록 준비할 필요가 있음을 제안하고 있다.
