Social Security is the largest source of retirement income for most Americans. Yet many people have only a vague understanding of how their benefit is calculated and how dramatically their claiming age affects their monthly check. Making an uninformed decision about when to claim can cost you tens of thousands of dollars over a long retirement.
This guide explains how Social Security works in 2026, how your benefit is calculated, when you can claim, and the key factors to consider when deciding the right time for you.
How Social Security Benefits Are Calculated
Your Social Security retirement benefit is based on your earnings history. The Social Security Administration (SSA) takes your 35 highest-earning years, adjusts them for inflation, and uses a formula to calculate your Primary Insurance Amount (PIA). That PIA is the monthly benefit you receive if you claim at your Full Retirement Age (FRA).
If you worked fewer than 35 years, the SSA fills in the missing years with zeros, which brings down your average and reduces your benefit. This is worth knowing if you are considering early retirement and wondering whether working a few additional years would meaningfully boost your benefit.
Full Retirement Age (FRA) in 2026
Your Full Retirement Age is when you are entitled to 100% of your calculated benefit. FRA depends on your birth year:
- Born 1960 or later: FRA is age 67
- Born 1955–1959: FRA is between 66 and 67 (increments of 2 months per year)
- Born before 1955: FRA is 66
For anyone reading this who was born in 1960 or later, FRA is 67.
When Can You Claim Social Security?
You can begin claiming as early as age 62, or you can delay beyond your FRA up to age 70.
Early claiming (age 62): If you claim before FRA, your benefit is permanently reduced. Claiming at 62 with an FRA of 67 reduces your benefit by 30%. That reduction lasts for the rest of your life and your survivor’s life.
Delayed claiming (past FRA): For every year you delay claiming beyond FRA, your benefit increases by 8% per year (called delayed retirement credits) up to age 70. Waiting from 67 to 70 increases your benefit by 24%. This is a guaranteed 8% annual return, which is extremely competitive.
Claiming at FRA: You receive 100% of your calculated benefit.
The Break-Even Analysis
A common way to think about claiming strategy is the break-even point: at what age does the higher lifetime payout from waiting outweigh the years of smaller payments you forfeited?
The break-even between claiming at 62 vs. 67 is typically around age 78 to 80. If you live past 80, you collect more total dollars by waiting. If you die before 80, early claiming paid more.
The break-even between claiming at 67 vs. 70 is typically around age 82 to 83. If you live well into your 80s or 90s, delaying to 70 often results in significantly higher lifetime income.
The average American who reaches age 65 today is expected to live to approximately age 85. That means the average person benefits from delaying. But averages mask individual variation, and your health history matters more than averages.
Factors That Should Influence Your Decision
Health and life expectancy. If you have serious health issues that reduce your life expectancy, claiming early may make sense. If you are in excellent health with longevity in your family, delaying is generally advantageous.
Spouse’s benefit. If you are married, your claiming decision affects your spouse’s survivor benefit. The surviving spouse receives the higher of the two benefits at death. If you are the higher earner, delaying maximizes the survivor benefit your spouse could receive for decades after you are gone.
Your other retirement income. If you have a pension, significant savings, or a working spouse, you may be able to afford to delay Social Security and let it grow. If Social Security is your primary income source and you need the money, claiming earlier may be necessary.
Whether you are still working. If you claim Social Security before FRA while still working and you earn over $22,320 per year (the 2026 earnings limit), the SSA withholds $1 of benefits for every $2 you earn above that limit. The withheld benefits are later added back to your monthly payment after FRA, but the short-term reduction can be jarring.
Spousal and Survivor Benefits
If you are married, divorced (after a marriage of at least 10 years), or widowed, you may be eligible for benefits based on your spouse’s or former spouse’s record.
Spousal benefits: A spouse who did not work or earned less can claim up to 50% of the higher-earning spouse’s benefit at FRA. You cannot apply for spousal benefits until the primary earner has claimed.
Survivor benefits: A surviving spouse can receive up to 100% of the deceased spouse’s benefit, including delayed credits if the deceased claimed after FRA. This is one of the strongest reasons for the higher earner in a couple to delay claiming as long as possible.
How to Get Your Benefit Estimate
Create a My Social Security account at ssa.gov. Once logged in, you can see your full earnings history, verify it for errors, and view projected benefit amounts at different claiming ages. Review your earnings history at least once before retiring to catch any unreported income that could be corrected.
Taxes on Social Security
Social Security benefits may be taxable depending on your combined income (adjusted gross income plus non-taxable interest plus half of your Social Security benefits).
- Combined income below $25,000 (single) or $32,000 (joint): benefits are not taxable
- Combined income $25,000 to $34,000 (single) or $32,000 to $44,000 (joint): up to 50% of benefits are taxable
- Combined income above $34,000 (single) or $44,000 (joint): up to 85% of benefits are taxable
This is not a 50% or 85% tax rate — it means up to that percentage of your benefit is included in your taxable income. Roth conversions and careful retirement account withdrawal strategies can reduce how much of your Social Security is taxed.
The Bottom Line
For most people who are in good health, delaying Social Security benefits, ideally to 70 for the higher-earning spouse in a couple, results in a significantly higher lifetime payout. The 8% per year increase from delaying past FRA is a guaranteed return that is very difficult to beat elsewhere. If you need the money earlier or your health warrants it, claiming at FRA or even earlier is a reasonable choice. The key is making an informed decision, not just claiming at 62 because that is the earliest option available.
