Social Security is the foundation of retirement income for most Americans. For many retirees, it represents 30%–50% or more of their total income. But the decisions around when to claim benefits are complex, and the stakes are high — a wrong choice can mean tens of thousands of dollars less over a lifetime.
This guide covers how Social Security benefits are calculated, when you can claim, the trade-offs of different claiming ages, and how to think about the right strategy for your situation.
How Social Security Benefits Are Calculated
Your Social Security benefit is based on your 35 highest-earning years, adjusted for inflation. The Social Security Administration (SSA) calculates your Average Indexed Monthly Earnings (AIME) and then applies a formula to determine your Primary Insurance Amount (PIA) — the benefit you receive if you claim at exactly your full retirement age (FRA).
The PIA formula in 2026 applies three “bend points”:
- 90% of the first $1,174 of AIME per month
- 32% of AIME between $1,174 and $7,078 per month
- 15% of AIME above $7,078 per month
This formula is deliberately progressive: lower earners replace a larger percentage of their pre-retirement income than higher earners.
You can see your estimated benefit anytime at SSA.gov by creating a My Social Security account. This shows your projected benefit at different claiming ages based on your actual earnings record.
Full Retirement Age in 2026
Your full retirement age (FRA) is the age at which you receive your full PIA — the benefit amount calculated from your earnings record. FRA is determined by birth year:
- Born 1943–1954: FRA is 66
- Born 1955: FRA is 66 years and 2 months
- Born 1956: FRA is 66 years and 4 months
- Born 1957: FRA is 66 years and 6 months
- Born 1958: FRA is 66 years and 8 months
- Born 1959: FRA is 66 years and 10 months
- Born 1960 or later: FRA is 67
Most workers born in 1960 or later have an FRA of 67.
When Can You Claim Social Security?
You can claim Social Security retirement benefits as early as age 62, or as late as age 70. The age you choose has a dramatic effect on the monthly benefit amount.
Claiming Early (Age 62)
Claiming at 62 — the earliest possible age — permanently reduces your benefit. If your FRA is 67, claiming at 62 reduces your monthly benefit by 30%. This reduction is permanent and does not go away when you reach FRA.
On a $1,800/month FRA benefit, claiming at 62 reduces it to approximately $1,260/month. Over a 25-year retirement, that difference amounts to approximately $162,000 in lost lifetime benefits (before considering cost-of-living adjustments).
Claiming at Full Retirement Age
Claiming at your FRA gives you 100% of your calculated benefit. No reductions, no enhancements.
Delaying Beyond FRA (Up to Age 70)
For every year you delay claiming past FRA, your benefit increases by 8% — guaranteed, with no market risk. This is called delayed retirement credits. Delaying from age 67 to 70 increases your monthly benefit by 24%.
On a $1,800/month FRA benefit, delaying to 70 gives you approximately $2,232/month. Over a long retirement, this difference is enormous.
The Break-Even Analysis
The break-even point is the age at which the total lifetime benefits from delaying surpass the total from claiming early. For most people with FRA of 67:
- Early claim (62) vs FRA (67): Break-even around age 80
- FRA (67) vs delayed (70): Break-even around age 82–83
If you live past the break-even age, delaying was the financially better decision. If you die before it, claiming early would have yielded more total lifetime benefits.
Since average life expectancy for Americans who reach age 65 is around 84–86, most people will live past the break-even point. This is one reason many financial planners recommend delaying to 70 for those in good health who can afford to wait.
Factors That Should Influence Your Claiming Decision
Health and Life Expectancy
If you have serious health issues or a family history of shorter lifespans, claiming earlier may make more sense. If you are in excellent health and expect to live into your late 80s or beyond, delaying to 70 is often optimal.
Financial Need
If you have no other income and need Social Security to pay bills at 62 or 63, you may have no choice but to claim early. But if you have savings, a pension, or a working spouse, you may be able to delay and earn significantly more over your lifetime.
Spousal Benefits and Survivor Benefits
Married couples have additional complexity. A spouse can receive up to 50% of the higher earner’s benefit. When the higher earner dies, the surviving spouse can switch to the deceased’s benefit if it is larger.
This makes the delaying decision especially powerful for the higher-earning spouse in a couple. A higher benefit at 70 means a higher survivor benefit for the remaining spouse — potentially for decades.
Working While Collecting
If you claim before FRA and continue working, Social Security withholds $1 in benefits for every $2 you earn above an annual limit ($22,320 in 2026). This effectively forces a delay or reduction in benefits. The withheld amounts are credited back to you once you reach FRA, increasing your monthly benefit going forward.
After FRA, you can work and collect Social Security simultaneously with no earnings limit.
Social Security Taxation
Social Security benefits may be partially taxable depending on your combined income (adjusted gross income + non-taxable interest + 50% of Social Security benefits):
- Below $25,000 (single) / $32,000 (married): Benefits are not taxable.
- $25,000–$34,000 (single) / $32,000–$44,000 (married): Up to 50% of benefits may be taxable.
- Above $34,000 (single) / $44,000 (married): Up to 85% of benefits may be taxable.
This has important implications for retirement account withdrawal strategies. Drawing from a Roth IRA instead of a traditional IRA in retirement can keep your combined income below the thresholds and reduce Social Security taxation.
Spousal and Dependent Benefits
Social Security provides benefits beyond the worker’s own retirement benefit:
- Spousal benefit: A spouse can receive up to 50% of the worker’s FRA benefit, regardless of the spouse’s own earnings record.
- Divorced spouse benefit: A divorced spouse who was married for at least 10 years can claim on the ex-spouse’s record.
- Survivor benefit: A widowed spouse can receive 100% of the deceased worker’s benefit.
- Child benefit: Dependent children under 18 may receive benefits based on a parent’s Social Security record.
Social Security’s Long-Term Finances
The Social Security trust fund is projected to face a shortfall around 2033–2035 under current projections. At that point, incoming payroll taxes would cover approximately 75–80% of scheduled benefits. Congress has historically acted to shore up Social Security before trust fund depletion — but the uncertainty is real for younger workers.
Most financial planners conservatively assume a 75–80% benefit for workers who are decades from retirement when doing long-term planning. Claiming this will definitely happen would be premature — but completely ignoring the risk is also unwise.
How to Check Your Estimated Benefit
Visit SSA.gov and create a My Social Security account. The portal shows:
- Your complete earnings record
- Estimated monthly benefits at ages 62, FRA, and 70
- Estimated disability and survivor benefits
Review this annually to make sure your earnings are recorded correctly. Errors in your earnings record can reduce your eventual benefit.
Final Thoughts
The Social Security claiming decision is one of the most consequential financial choices you will make. For most people in good health with the financial flexibility to wait, delaying to 70 maximizes lifetime benefits. But the right answer depends on your health, finances, marital status, and overall retirement income strategy.
