本文分析現在的退休金制度和老年經濟安全保障的情形，同時討論家庭所得來源的趨勢，並推估未來退休後所需的費用。最後提供予個人儘早為自己做一些規劃與準備的建議。老年經濟安全保障在台灣地區因為各項因素的影響，顯得十分不足，經由收集資料並分析比較後，以15～64歲的人口來看老年經濟安全三層的保障情況，其中佔4％的軍公教人員有較完整的退休保障制度；佔50％的勞工人口，在第一層的保障中，於2000年平均勞保老年給付每人658,273元。又因為制度未臻完善，第二層之保障只有1～2％的人可以領到退休金。此外，佔有7％的農民在年滿65歲之後，只有不完整的第一層保障，即每月3,000元的老農津貼可領。其他39％的人是未參加公保、勞保或農保等任一項社會保險的。也就是有95％的人是需要儘早規劃退休後的經濟準備。面對大環境中的財政赤字及個人平均壽命的增長，子女親朋經濟支援的減少等等因素，更顯得及早規劃老年經濟安全的迫切性。 關鍵詞：老年經濟安全保障、退休金、國民年金、生活費用推估、所得替代率 / This study focused on investigation and evaluation of the pension system and economic security program in Taiwan.

The labores, about 50 percent of the work force, have the everage amount NT$658,273 for the 1^st-tier social security and benefit in 2000. Due to the unsound system and the qualiication problem, less than two percent of the laborers can obtain the 2^nd-tier pension. Beside, farmers, about seven percent of the work force, can obtain the 1^st-tier social security and benefit until they are 65 years old or more.
