How the benefit is calculated
Social Security uses your highest 35 years of inflation-adjusted earnings (the "Average Indexed Monthly Earnings" or AIME). If you worked fewer than 35 years, the missing years count as zero.
The Primary Insurance Amount (PIA) formula for 2026 retirees
- 90 percent of the first $1,226 of AIME
- 32 percent of AIME from $1,226 to $7,391
- 15 percent of AIME above $7,391
The "bend points" ($1,226 and $7,391) update annually with the National Average Wage Index. The progressive structure means low earners get a higher replacement rate (~78 percent of pre-retirement earnings) than high earners (~28 percent).
Maximum Social Security benefit at FRA (67) in 2026: $4,043/month for someone who earned the max taxable wage ($176,200) for at least 35 years. At age 70 with delayed credits: $4,925/month.
At age 62 with maximum reduction: $2,832/month (same earnings record, just claimed early).
Average benefit for retired worker in 2026: about $1,976/month.
COLA (Cost of Living Adjustment): based on CPI-W (third quarter prior to claim year). 2026 COLA was 2.5 percent (announced October 2025), down from 3.2 percent in 2024 and 8.7 percent in 2023.
The earnings test: under FRA, $1 is withheld for every $2 earned above $22,320 (2026 estimate). In the year of FRA, withhold $1 for every $3 above $59,520. After FRA, no earnings test.
Claim age decision: 62 vs FRA vs 70
The break-even math is the easiest place to start.
Claim at 62 with FRA 67: 30 percent permanent reduction. You collect 5 extra years (60 months) but at 70 percent.
Claim at FRA 67: full PIA.
Claim at 70: 32 percent permanent boost. You skip 3 years but at 132 percent.
| For a $2,000 FRA benefit | Cross-over points (assuming no inflation, no investment of payments) |
|---|---|
| Age 62 benefit: $1,400/month, $84,000 collected by age 67 | 62 vs 67: equal cumulative payouts at about age 77 |
| Age 67 benefit: $2,000/month, $0 collected by age 67 | 67 vs 70: equal at about age 82 |
| Age 70 benefit: $2,640/month, $0 collected by age 70 | 62 vs 70: equal at about age 80 |
If you live past 80-82, delaying wins. If your family has short longevity or you have health issues: claim earlier.
The "actuarial fair" age in social-security tables is about 82 for a single person at FRA. Delayed claim retiree life expectancy at 70 is 86. So the delay benefits a typical retiree who reaches 70+.
Other factors
- Spousal benefit: claiming early reduces spouse's survivor benefit. The lower earner should claim earlier; the higher earner should delay.
- Roth conversion strategy: delaying SS lets you do bracket-fill Roth conversions in your 60s at lower brackets.
- Health insurance: SS does not affect Medicare (which starts at 65 regardless of SS).
- Other retirement income: pension, RMDs at 73 - SS combines with these.
| Claim age | Monthly benefit | vs FRA | Annual |
|---|---|---|---|
| 62 (earliest) | $2,832 | -30% | $33,984 |
| 65 | $3,371 | -17% | $40,452 |
| 67 (FRA) | $4,043 | Base | $48,516 |
| 68 | $4,366 | +8% | $52,392 |
| 70 (max) | $4,925 | +22% | $59,100 |
Spousal, survivor, divorce + new Fairness Act
Spousal benefit (married): up to 50 percent of higher earner FRA benefit, paid to the lower earner. The lower earner gets the GREATER of their own benefit or 50 percent of spouse FRA benefit. Both must claim before spousal benefit triggers.
Survivor benefit (widowed): surviving spouse can receive 100 percent of deceased spouse benefit (if deceased had reached FRA; or actuarial reduction if earlier). Surviving spouse can claim as early as 60 (50 if disabled).
Claim strategy for couples: lower earner claims at 62 (some current income, smaller permanent reduction in absolute dollars); higher earner delays to 70 (maximize survivor benefit and personal benefit).
Divorce: if married 10+ years and now unmarried, you can claim 50 percent of ex-spouse FRA benefit, even if your ex has not yet claimed. Ex-spouse cannot block. Your benefit does not affect ex-spouse benefit. Remarriage before age 60 invalidates this; remarriage after 60 preserves it.
2025 Social Security Fairness Act: signed into law January 2025, eliminated the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO). Approximately 3 million state/local government workers, teachers, firefighters, and police whose pensions were not covered by Social Security but who also had OTHER Social Security earnings had their benefits reduced by WEP/GPO. Effective for benefits payable January 2024 onward (retroactive). Average estimated benefit increase: $360-$1,200/month depending on situation. Pre-existing claims will be recalculated; back-pay processed throughout 2025-2026.
If you previously thought "I cannot get full SS because of my teacher pension" - reapply or check SSA.gov. Your benefit calculation just got better.
Earnings test and taxation of benefits
Working while claiming Social Security under FRA triggers the earnings test
- 2026 limit: $22,320/year earnings before reduction
- Above limit: $1 SS benefit withheld for every $2 of excess earnings
- Year of FRA: limit rises to $59,520, withhold $1 for every $3 excess
- After FRA: no earnings test, work and full benefit
Withheld benefits are NOT lost. SSA recalculates and pays them back as a higher monthly benefit at FRA.
Taxation of Social Security benefits (provisional income test)
- Single: $25,000-$34,000 provisional income: 50 percent of SS taxable; over $34,000: 85 percent
- Married jointly: $32,000-$44,000: 50 percent; over $44,000: 85 percent
- Provisional income = AGI + tax-exempt interest + 50 percent of SS benefit
Most middle-class retirees pay tax on 85 percent of their SS benefit (the highest tier). State tax varies: 12 states tax SS in 2026 (Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, West Virginia). 38 states + DC do NOT tax SS.
Strategy: keep AGI low in early retirement to minimize SS tax. Roth conversions help (do them BEFORE claiming SS).
Common claiming mistakes
- Claiming at 62 by default. Reduces benefit 30 percent permanently. Run the math.
- Forgetting that delay credits stop at 70. Delaying past 70 does not increase benefit. Claim at 70 regardless.
- Not enrolling in Medicare at 65. 10 percent Part B premium penalty for every year of delay - for LIFE.
- Married couples both claiming early. If higher earner delays, survivor gets larger benefit. Coordinate.
- Ignoring divorce option. 10+ year marriage entitles you to 50 percent of ex-spouse FRA. Many do not check.
- Pre-2025 WEP/GPO assumption. Fairness Act eliminated them. Government workers should reapply.
- Filing for "restricted application" - eliminated for those born 1954+. Cannot file for spousal only while delaying own benefit anymore.
- Forgetting earnings test under FRA. Withheld benefits return as larger monthly later, but cash flow gap meanwhile.
- Not factoring SS tax into retirement budgeting. 85 percent of SS often taxable.
- Letting SSA mistakes go uncorrected. Earnings record errors compound over 35-year averaging. Check annual statement on my.ssa.gov.
