Social security age calculator
Claiming ages are checked against your age on a specific date. Set the second date to the claiming date and read the exact age. Full retirement age is 67 for anyone born in 1960 or later in the US system.
How to check your age at a claiming date
US Social Security has a specific quirk worth knowing: benefits are payable from the month you attain the age, and someone born on the first of a month is treated as attaining it in the previous month. Similar month-boundary rules exist in other national schemes. Where a claim date sits near a boundary, the scheme own calculator is the authority. This one gives you the exact age to check it against.
