How we worked it out
Updated as you change the numbers.
- Full retirement age for 1,964: 67 years 0 months.
- Claiming at full retirement age: 100% of your benefit.
Method and assumptions
These are the reduction and delayed-credit rules in the Social Security Act: benefits fall by 5/9 of 1% for each of the first 36 months claimed before full retirement age and 5/12 of 1% for each month beyond that, and rise by 2/3 of 1% for each month you wait past full retirement age, until 70. Full retirement age is 67 for anyone born in 1960 or later. These rules are fixed in law; your own benefit amount comes from your SSA statement, so no yearly figures are stored here.
Questions
