Frequently asked questions
What age is 'full retirement age'?
For most people born in 1960 or later, full retirement age is 67; claiming earlier or later adjusts your benefit down or up.
How much more do I get by waiting until 70?
Delaying past full retirement age increases your benefit by roughly 8% per year up to age 70.
Is this an official benefit estimate?
No — this is a simplified illustration; for an official estimate, check your Social Security Statement at ssa.gov.
