The Social Security benefit calculation
PIA = sum of bend-point percentages of your AIME · · · Benefit = PIA × claim-age adjustment
Your Primary Insurance Amount (PIA) is based on your top 35 years of indexed earnings. Claiming before full retirement age reduces benefits by up to 30%; claiming after increases them by 8% per year up to age 70.
Worked example
A worker with a PIA of $2,500 at full retirement age 67: at 62 the benefit is $1,750 (30% reduction); at 67 it's $2,500; at 70 it's $3,100 (24% increase). Over a 20-year retirement, the age-70 claim provides roughly $324,000 more than age 62.
Frequently asked questions
Should I claim early at 62 or wait?
Mathematically, waiting wins for anyone reaching average life expectancy. Claiming early makes sense for those with health issues, no spouse who would benefit from survivor benefits, or pressing immediate income needs.
How does spousal benefit work?
A spouse can claim up to 50% of the higher earner's PIA at full retirement age. Survivor benefits can go up to 100% of the deceased spouse's benefit including any delayed retirement credits.
Will Social Security be there for me?
Trust fund projections suggest benefits could be reduced to about 77% of scheduled levels around 2034 absent legislative action. Most planners assume some reduction but not elimination.
