Estimate your monthly benefit · Find the best age to claim · 2025
There is no universally 'best' age — it depends on your health, other income sources, and marital status. Claiming at 62 gives you more checks but each is permanently reduced by up to 30%. Waiting until 70 maximizes each check (32% more than at FRA). The break-even age — where lifetime benefits equalize — is typically around age 78–82. If you expect to live past your break-even age, delaying is usually beneficial.
For anyone born in 1960 or later, FRA is 67. For those born 1955–1959, FRA ranges from 66 years and 2 months to 66 years and 10 months. Claiming before FRA permanently reduces your benefit; claiming after FRA (up to age 70) permanently increases it by 8% per year via Delayed Retirement Credits.
The SSA uses your Average Indexed Monthly Earnings (AIME) — the average of your 35 highest earning years. Your AIME runs through the PIA formula: 90% of the first $1,226/month, 32% of AIME between $1,226–$7,391, and 15% above $7,391 (2025 bend points). The result is your monthly benefit at FRA.
Yes, but earnings limits apply. In 2025, if you're under FRA for the full year, SSA withholds $1 for every $2 you earn above $22,320. In the year you reach FRA, SSA withholds $1 for every $3 earned above $59,520. After FRA, you can earn unlimited income with no reduction. Withheld benefits are added back as a higher benefit once you reach FRA.
Up to 85% of your benefit may be taxable. If your combined income (AGI + half your SS benefit) is under $25,000 (single) or $32,000 (married), benefits are not taxable. Between $25k–$34k single ($32k–$44k married), up to 50% is taxable. Above those thresholds, up to 85% is taxable. 13 states also tax Social Security.
Everything above estimates your own retirement benefit based on your earnings record. If you're married, divorced after a long marriage, or widowed, Social Security has separate rules that can significantly change your household's optimal claiming strategy — and they're easy to miss if you only look at your own number.
Spousal benefits. A spouse can claim up to 50% of the higher earner's Primary Insurance Amount (PIA) at their own full retirement age, even with little or no work history of their own. If you'd qualify for a smaller benefit on your own record, SSA effectively pays you the higher of the two amounts — it doesn't stack on top. This makes it worth comparing your own projected benefit against 50% of your spouse's PIA before deciding who claims when.
Divorced spouse benefits. If your marriage lasted at least 10 years, you're currently unmarried, and you're 62 or older, you can claim spousal benefits on an ex-spouse's record — even if they've remarried — without affecting their benefit or their current spouse's benefit in any way. Many divorced people don't realize this option exists.
Survivor benefits work differently than spousal benefits. A widow or widower can receive up to 100% of the deceased spouse's benefit (versus the 50% cap on spousal benefits), starting as early as age 60 (age 50 if disabled), though claiming early permanently reduces the survivor amount. A common strategy for couples with a significant earnings gap: the lower earner claims their own reduced benefit early, while the higher earner delays to 70 — maximizing the benefit that will eventually convert to a survivor benefit for whichever spouse lives longer.
Because these rules interact with timing in non-obvious ways, couples generally benefit more from running scenarios together (SSA's own calculators, or a fee-only financial planner) rather than each spouse optimizing their claiming age independently.
