Key Takeaways
- Claiming at 62 locks in about 70% of your full benefit for life; waiting to 70 gives 124%.
- Full retirement age is 67 for anyone born in 1960 or later, who start reaching it in 2027.
- The 2027 maximum benefit is $5,358 a month at 70, or $4,188 at full retirement age.
- Before FRA, SSA withholds $1 for every $2 earned above $25,560 in 2027.
Claim Social Security at 62 and you lock in about 70% of your full benefit for life. Wait until 70 and you lock in 124%. For someone retiring in 2027 with a maxed-out earnings record, that’s the difference between about $3,094 and $5,358 a month.
That’s the biggest financial decision most retirees make, and you only get one do-over, in the first 12 months. I get more questions about “when should I file” than almost anything else, so here’s the real math for singles, couples and people who’ve already passed full retirement age.
The Core Decision: 62 vs. 67 vs. 70
You can start retirement benefits any time between 62 and 70. Your full retirement age (FRA) is 67 for anyone born in 1960 or later. 2027 is a milestone: people born in 1960 are the first to reach it, which finishes the FRA increase Congress passed in 1983.
Claim before FRA and your check is reduced for life, under SSA’s early claiming rules. The cut is 5/9 of 1% a month for the first 36 months early, then 5/12 of 1% a month after that. At 62, that adds up to a 30% reduction.
Wait past FRA and delayed retirement credits add 8% a year until 70. Three years of waiting raises your benefit 24%.
| Claim at | % of full benefit | Sarah’s check (FRA benefit $2,400) |
|---|---|---|
| 62 | 70% | $1,680 |
| 67 | 100% | $2,400 |
| 70 | 124% | $2,976 |
Sarah’s check at 70 is 77% bigger than at 62, from the exact same earnings record. Every one of those amounts also gets each year’s COLA on top, including the 3.6% for 2027.
There’s no universal right age. Poor health, a need for income now or a job you can’t keep doing all argue for claiming earlier.
Good health, other money to live on and a family history of long lives argue for waiting. The break-even age, where waiting pulls ahead in total dollars, usually falls around 78 to 80.
Working While You Collect Before 67
If you claim early and keep working, the earnings test can hold back part of your check. For 2027, SSA withholds $1 for every $2 you earn above $25,560 (up from $24,480 in 2026).
In the calendar year you reach FRA, the limit rises to $67,920, with $1 withheld for every $3 over, and only earnings before your birthday month count. Once you reach FRA, there’s no limit at all.
Tony claims at 63 in January 2027 and earns $35,560 at a part-time job. He’s $10,000 over the limit, so SSA withholds $5,000 of his benefits for the year.
That money isn’t gone: at FRA, SSA raises his monthly check to credit back the withheld months. SSA’s earnings test page has the details.

Already Past 67? The Retroactive Lump Sum
If you’re past FRA and haven’t filed, you can ask SSA to backdate your claim up to six months and pay those months as a lump sum. You can’t go back before your FRA month.
The catch: your filing date moves back too, so you give up the delayed credits for those months. Six months of back pay permanently lowers your monthly check by 4% (six months at two-thirds of 1% each).
David turned 67 in March 2026 and is still working. If he files in January 2027 and asks for six months back, he gets a lump sum of about $12,600 on a $2,100 benefit. His ongoing check is about $84 a month lower for life than if he’d taken no back pay.
Whether that’s worth it depends on what the cash does for you. Paying off high-interest debt or covering a big medical bill can justify it.
If you don’t need the money, skipping the lump sum usually wins. It’s also taxable in the year you get it, so a smaller number of back months, or timing it for a lower-income year, can save tax.
How Married Couples Get the Most
For couples, the goal isn’t two big checks. It’s the most total household income over both lifetimes, including the years one spouse lives alone.
The approach that usually wins for couples with an earnings gap: the lower earner claims earlier, as early as 62, for household cash flow. The higher earner waits until 70 to make their check as large as possible.
That’s because of survivor benefits. When one spouse dies, the survivor keeps the larger of the two checks, and the smaller one stops.
Delaying the higher earner’s claim protects whoever lives longer. My Social Security survivor benefits guide covers those rules in detail.
Mark and Linda show the ceiling. Both earned at or above the taxable maximum for 35 years and both wait until 70 in 2027. Their combined check is $10,716 a month, about $128,600 a year.
Few couples get there, but the same stagger works at any income.
Divorced? If your marriage lasted at least 10 years and you haven’t remarried, you may be able to claim up to 50% of your ex-spouse’s full benefit. It doesn’t reduce what they or their current spouse receive.

The $5,358 Maximum: Who Actually Gets It
The maximum Social Security benefit for someone who claims at 70 in 2027 is $5,358 a month, up from $5,181 in 2026. The bar is much higher than the headlines suggest. You need both:
- 35 years of earnings at or above the taxable maximum, which is $192,300 in 2027 (it was $184,500 in 2026). Any lower year pulls your average down.
- Claiming at exactly 70, to collect the full 24% in delayed credits.
Claim at 67 with the same record and the 2027 maximum is $4,188. Claim at 62 and it’s $3,094.
Most people are nowhere near those numbers. The average retired worker gets about $2,170 a month in 2027, after the 3.6% COLA. My average Social Security check by state page shows how that varies across the country.
Claiming Mistakes I See Every Year
Treating break-even age as the whole answer. It’s one data point. Health, other income and a spouse’s survivor needs matter just as much.
Missing the 12-month do-over. You can withdraw your application within 12 months if you repay everything you’ve received. After that, an early claim is permanent.
Filing at the same age as your spouse by default. Both at 62, or both at 70, is rarely the best choice for a couple with different earnings.
Not budgeting for Medicare. At 65, most people’s Part B premium comes out of the Social Security check. It was $202.90 in 2026; CMS sets 2027’s in November. My 2026 Medicare changes and 2027 outlook has the latest.
Confusing delayed credits with the COLA. The 8% a year for waiting is on top of every COLA, not instead of it.
What Could Change Claiming in 2028 and Beyond
No further increase to full retirement age is scheduled, so 67 is the number for anyone born in 1960 or later. That only changes if Congress passes a new law.
The bigger story is the trust fund. The trustees project the retirement fund runs short in late 2032, when payroll taxes would cover about 78% of benefits. Every fix on the table, from raising the taxable maximum to adjusting the benefit formula or retirement age, would change this math for younger workers.
Here’s what I’m watching for 2028:
- The 2028 COLA, announced in mid-October 2027. It raises every claimant’s check, early or late.
- The 2028 taxable maximum and earnings test, which rise with national wages and are announced the same day.
- The 2027 Trustees Report, due next spring, which will update the 2032 date.
My 2027 COLA breakdown will track the first 2028 estimates. Once you’ve filed, my Social Security payment schedule by birth date shows when your check lands each month.
