How is social security calculated?

Social Security benefits are reduced if you claim before Full Retirement Age (FRA). The reduction is 5/9 of 1% per month for the first 36 months, then 5/12 of 1% per month after that. If you claim after FRA, you earn delayed retirement credits of 8% per year until age 70. The breakeven age is when delaying results in higher cumulative lifetime benefits.

What is the formula for social security?

The formula used is: Benefit = PIA × (1 − reduction per month before FRA)

What is my Full Retirement Age?

Your FRA depends on your birth year. For those born 1960 or later, FRA is 67. For those born 1943-1954, it's 66. FRA increases by 2 months per year for birth years between 1955 and 1959.

Is it always better to delay claiming?

Not necessarily. If you have a shorter life expectancy or need the income earlier, claiming before FRA may be the right choice. The breakeven age calculation shows that delaying only pays off if you live past your late 70s or early 80s.

Can I work while collecting Social Security?

Yes, but if you're under FRA, your benefits may be temporarily reduced. In 2026, you lose $1 in benefits for every $2 earned above $22,320. Once you reach FRA, there's no penalty regardless of how much you earn.

When to Claim Social Security

Deciding when to claim Social Security is one of the most important retirement decisions you'll make. Claiming at 62 (the earliest) permanently reduces your monthly benefit by up to 30%. Waiting until age 70 increases it by 24-32% through delayed retirement credits.

The key metric is your breakeven age — the point where total cumulative benefits from delaying surpass those from claiming early. For most people, this falls between ages 77 and 82, making it a bet on longevity. If you expect to live past your breakeven age, delaying maximizes lifetime income.
