What this doesn't model
- COLA (annual cost-of-living adjustment) — real-dollar breakeven shifts ~2-4 years older.
- Taxes on Social Security (depends on combined income).
- Spousal / survivor benefits, divorced-spouse rules, earnings test before FRA.
- Windfall Elimination Provision / Government Pension Offset (if you had non-covered work).
- Tax-deferred portfolio dynamics — claiming later may save your portfolio more than the SS gain itself.
How this is calculated
- FRA: 1937 and earlier = 65; 1943–1954 = 66; 1960+ = 67 (interpolated in between per SSA schedule).
- Early reduction: first 36 months early = 5/9 of 1% per month; beyond = 5/12 of 1% per month.
- Delayed credit: 8% per year (2/3 of 1% per month) up to age 70.
- Lifetime = monthly × 12 × (life_age − claim_age). Breakeven solves for the age where cumulative claim-age payout equals cumulative FRA payout.
