62到67也是每年增加约8%

用你给的数据：

Maximum Benefit Amount (2025):

• $2,831 per month: This is the maximum benefit for those who claim as early as possible at age 62. 

• $5,108 per month: This is the top benefit for high earners who delay claiming their benefits until age 70.   
   
• $4,018 per month: This is the maximum benefit for those who claim at their full retirement age

 

$4018 / $2831 = 1.42, 也就是说： 62到67，5年推迟会增多退休金42%，约8%/每年。
