Key Planning Factors
"The single most important financial decision many retirees make is when to claim Social Security — yet most claim as early as possible without doing the math."

How Social Security benefits are calculated
Your Social Security retirement benefit is based on your 35 highest-earning years, indexed to wage inflation. The SSA converts these into your Average Indexed Monthly Earnings (AIME), then applies a progressive formula to arrive at your Primary Insurance Amount (PIA) — your benefit at Full Retirement Age.
Your Full Retirement Age (FRA) depends on your birth year. For anyone born in 1960 or later, FRA is 67. For those born between 1955–1959, FRA phases from 66 and 2 months to 66 and 10 months.
Claiming before FRA permanently reduces your benefit — by 5/9 of 1% per month for the first 36 months early, and 5/12 of 1% per month beyond that. Claiming at 62 (the earliest age) reduces your benefit by about 30% for those with an FRA of 67.
Delaying beyond FRA earns Delayed Retirement Credits of 8% per year (2/3 of 1% per month). Waiting from FRA to 70 increases your benefit by 24% — the maximum bonus.

If your FRA benefit is $2,000/month:
| Claim Age | Monthly Benefit | vs. FRA | Annual |
|---|---|---|---|
| 62 | $1,400 | -30% | $16,800 |
| 63 | $1,500 | -25% | $18,000 |
| 64 | $1,600 | -20% | $19,200 |
| 65 | $1,733 | -13.3% | $20,800 |
| 66 | $1,867 | -6.7% | $22,400 |
| 67 (FRA) | $2,000 | 0% | $24,000 |
| 68 | $2,160 | +8% | $25,920 |
| 69 | $2,320 | +16% | $27,840 |
| 70 | $2,480 | +24% | $29,760 |
Waiting from 62 to 70 increases the monthly check by 77%. Break-even vs. claiming at FRA: roughly age 80.
Social Security FAQs
When should I claim Social Security?
It depends on health, other income sources, and whether you're married. If you have reason to expect a shorter-than-average lifespan or need income immediately, early claiming may make sense. If you're healthy and have other resources to cover expenses, waiting typically maximizes lifetime benefits. For married couples, the higher earner waiting until 70 can significantly increase survivor benefits.
What is the earnings test?
If you claim before FRA and continue working, SSA withholds $1 in benefits for every $2 you earn above the annual exempt amount ($22,320 in 2024). In the year you reach FRA, the limit rises to $59,520 and the withholding rate drops to $1 per $3. At FRA and beyond, there is no earnings test — you keep all benefits regardless of work income.
How does marriage affect benefits?
A spouse can claim a spousal benefit of up to 50% of the higher earner's FRA benefit — if that's more than their own earned benefit. Spousal benefits are reduced if claimed before the spouse's own FRA. Divorced spouses married for 10+ years may also qualify. Surviving spouses can claim the deceased spouse's full benefit.
Are Social Security benefits taxable?
Potentially yes. If your "combined income" (AGI + nontaxable interest + half of SS benefits) exceeds $25,000 (single) or $32,000 (married filing jointly), up to 50–85% of your benefits become taxable at your ordinary income rate. This threshold has not been adjusted for inflation since 1984, so most moderate-income retirees pay some tax on benefits.
Social Security terminology
Full Retirement Age (FRA)
The age at which you receive 100% of your Primary Insurance Amount. For those born 1943–1954: age 66. For 1955–1959: phases from 66+2mo to 66+10mo. For 1960 and later: age 67.
Primary Insurance Amount (PIA)
Your monthly benefit at Full Retirement Age, calculated from your Average Indexed Monthly Earnings using SSA's progressive benefit formula. This is what your Social Security statement shows as your "estimated benefit."
Delayed Retirement Credits (DRC)
The increase in your benefit for each month you delay claiming beyond FRA, up to age 70. Currently 8% per year (2/3 of 1% per month). Claiming at 70 vs. FRA 67 earns 3 years × 8% = 24% more per month for life.
Cost-of-Living Adjustment (COLA)
An annual inflation adjustment to Social Security benefits, tied to the Consumer Price Index for Urban Wage Earners (CPI-W). The 2024 COLA was 3.2%. Benefits automatically increase each January — a key advantage of SS over fixed annuities.
Break-Even Age
The age at which cumulative lifetime benefits from a later claiming strategy overtake those from an earlier strategy. Typically age 80–82 for waiting from 62 to FRA; age 82–84 for waiting from FRA to 70. If you live beyond break-even, the later claiming strategy pays more total.
Survivor Benefit
A surviving spouse can claim up to 100% of the deceased spouse's benefit if it exceeds their own. This makes the higher earner's claiming age a legacy decision — waiting until 70 maximizes the survivor benefit available to a lower-earning spouse for the rest of their life.
