The Social Security Benefits Calculator models the impact of your claiming age on monthly and cumulative lifetime retirement benefits under United States Social Security Administration (SSA) rules.

### SSA Retirement Formula & Claiming Age Adjustments Your Social Security benefit is based on your Primary Insurance Amount (PIA)—the monthly benefit you are entitled to receive at Full Retirement Age (FRA, age 67 for individuals born in 1960 or later): - Age 62 (Earliest Eligibility): Claiming at age 62 reduces monthly benefits to 70% of your PIA (a 30% lifetime reduction due to 60 early claiming months). - Age 67 (Full Retirement Age): Claiming at FRA delivers exactly 100% of your PIA baseline. - Age 70 (Delayed Retirement Credits): For every year you delay claiming past age 67 up to age 70, your benefit increases by 8% per year (+24% total), resulting in a monthly payout equal to 124% of your PIA.

### Cumulative Lifetime Payout & Break-Even Analysis Lifetime total benefits depend on longevity and the total months spent collecting: $$\text{Total Lifetime Benefit} = \text{Monthly Payout} \times 12 \times \max(0, \text{Life Expectancy} - \text{Claiming Age})$$ Delaying your claim provides larger monthly checks over fewer retirement years. For average life expectancies beyond age 78 to 80, delaying to age 67 or 70 yields a higher cumulative lifetime payout than claiming early at 62.

### Worked Benefit Example Consider a worker with an estimated **PIA of $2,200 per month at age 67** and a projected **life expectancy of 85 years**: 1. **Monthly Benefit by Age**: - Claim at 62: $\$2,200 \times 0.70 = \$1,540.00\text{ / month}$ - Claim at 67: $\$2,200 \times 1.00 = \$2,200.00\text{ / month}$ - Claim at 70: $\$2,200 \times 1.24 = \$2,728.00\text{ / month}$ 2. **Cumulative Lifetime Payout through Age 85**: - Claim at 62 ($23\text{ years} = 276\text{ months}$): $\$1,540 \times 276 = \$425,040.00$ - Claim at 67 ($18\text{ years} = 216\text{ months}$): $\$2,200 \times 216 = \$475,200.00$ - Claim at 70 ($15\text{ years} = 180\text{ months}$): $\$2,728 \times 180 = \$491,040.00$ 3. **Difference**: Delaying to age 70 delivers an additional **$66,000.00 in cumulative lifetime retirement income** compared to claiming at 62.
