For most Americans, Social Security is the largest single financial asset they will collect over the course of their retirement — larger, for many people, than their 401(k) or IRA. And yet most people make their claiming decision with surprisingly little analysis, often defaulting to “as soon as I can” without understanding the true cost of that choice.
The decisions adults over 50 make about Social Security — when to claim, in what sequence, how to coordinate with a spouse — can legitimately mean the difference of $100,000 to $300,000 or more in lifetime benefits. Understanding the basics is not just useful. It is one of the highest-return financial planning activities available to you.
How Your Benefit Is Calculated
Your Social Security retirement benefit is based on your 35 highest-earning years, adjusted for wage inflation. If you worked fewer than 35 years, the Social Security Administration fills the remaining years with zeros, which lowers your average. This is worth knowing if you are considering retiring early or stepping back from high-earning work — every additional high-earning year can replace a zero or a low-earning year in your calculation, potentially increasing your benefit meaningfully.
You can check your estimated benefit at any time by creating an account at ssa.gov, where the Social Security Administration provides a personalized earnings record and benefit estimate.
The Claiming Age Decision
You can claim Social Security as early as age 62, at your Full Retirement Age (FRA — currently 67 for anyone born in 1960 or later), or as late as age 70. Each year you delay past FRA increases your benefit by 8%. Each year you claim before FRA reduces it — by approximately 5–6% per year from 67 back to 62.
The math of waiting is compelling for most people. Claiming at 62 rather than 67 reduces your monthly benefit by approximately 30%. Claiming at 70 rather than 67 increases it by 24%. The breakeven age — the point at which waiting pays off cumulatively — is typically around 80 to 82. Given that average life expectancy for a healthy 65-year-old is well into the mid-80s, waiting is, for most people, the better bet.
There are legitimate reasons to claim early: poor health, an immediate financial need, or a job loss that makes waiting untenable. But “I want to get my money back” and “what if I die early” — the two most common reasons people give for claiming at 62 — are not strong mathematical arguments. The break-even point accounts for both scenarios.
Spousal and Survivor Benefits
For married couples, the Social Security claiming decision becomes a coordination problem that involves two people, two benefit histories, and the all-important survivor benefit.
A spouse is entitled to the higher of their own benefit or 50% of their spouse’s benefit at their spouse’s FRA. This is the spousal benefit — and it becomes particularly significant when one spouse has a much larger benefit history than the other, as is common in couples where one partner worked part-time, took years off for caregiving, or worked in lower-wage fields.
The survivor benefit is even more consequential. When one spouse dies, the surviving spouse retains the higher of the two benefits the couple was receiving. This means that the lifetime value of a high-earning spouse delaying their claim to age 70 is not just the benefit they collect — it is also the larger survivor benefit their spouse will receive, potentially for 20 or 30 years.
For this reason, financial planners often recommend a coordination strategy for couples: the lower-earning spouse may claim earlier to provide cash flow, while the higher-earning spouse delays to 70 to maximize the eventual survivor benefit. The specifics depend on both partners’ ages, health, and financial picture.
Social Security and the Pressure of Helping Your Children
One dynamic specific to adults over 50 is the temptation — or sometimes the necessity — to claim Social Security early in order to have resources available to help adult children. If you are 62, your children are in financial difficulty, and your Social Security benefit is your most readily available source of income, the early claim can feel like the practical solution.
Before making this decision, it is worth exploring whether there are other options that do not permanently reduce a benefit you will collect for the rest of your life. A part-time job, a temporary draw from savings, or a more candid conversation with your children about what you can sustainably provide may be better alternatives than locking in a permanently reduced benefit at 62. The 30% permanent reduction that comes from claiming at 62 versus 67 is not a one-time cost — it compounds over the entire length of your retirement.
Taxes on Social Security
Up to 85% of your Social Security benefit can be taxable, depending on your combined income (your adjusted gross income plus nontaxable interest plus half your Social Security benefit). At relatively modest combined income levels, benefits begin to be taxed. Understanding this matters for retirement income planning, particularly if you have significant retirement account withdrawals, investment income, or part-time work in early retirement.
A financial advisor or tax professional can help you model the tax implications of different withdrawal strategies alongside your Social Security income, which can sometimes meaningfully improve your after-tax retirement income through careful sequencing.
The One Action to Take Now
If you have not done so recently, create a free account at ssa.gov and review your earnings record and estimated benefits. Errors in your earnings record — which do occasionally occur — are far easier to correct before you claim than after. And seeing your actual projected benefit at 62, 67, and 70 is the most concrete first step in making a genuinely informed claiming decision.
This is one area of retirement planning where spending an hour with a Social Security-focused financial advisor or using a dedicated Social Security optimization tool (like Maximize My Social Security or Open Social Security) is likely to pay for itself many times over.
