E105: Social Security at 62 or 70: The Portfolio Math Nobody Runs

After 30 years of early call, missed holidays, and being the steady hand in a room where nothing can go wrong, retirement is supposed to buy back your time and your peace of mind. It’s important to keep in mind that the age you put on your Social Security application determines how much of that peace of mind survives your first bad market.

Claiming at 62 permanently reduces your benefit by about 30% compared to what you’d receive at full retirement age of 67, for anyone born in 1960 or later, as of 2026. Delaying to 70 increases your benefit by about 24% above that full retirement age amount. Financial advisors talk about this piece fairly often. Fewer talk about what a smaller, earlier check does for your portfolio during the first 10 years of retirement, the most fragile stretch of your entire financial timeline.

Timing carries this much weight because of something called sequence of returns risk. If the market drops hard in year one or two of retirement and you’re pulling a large chunk from your portfolio to live on, you’re selling investments at a loss to fund your lifestyle, and those losses may never fully recover even after the market comes back. A 20% drop in year one does much more damage than the same 20% drop in year fifteen, because by year fifteen your portfolio has had time to grow and can better absorb the hit. It’s a major reason claiming age functions more like portfolio protection than a pension decision.

Every dollar of Social Security you claim early is a dollar you don’t have to pull from your investments. Claim early, and you protect your portfolio during its most vulnerable years, at the cost of a smaller check for life. Delay, and you build a bigger, safer income floor for your 80s and 90s, while asking your portfolio to carry your full spending right out of the gate.

CRNAs and nurse practitioners face an earnings-record issue that standard retirement content doesn’t always address. If years of your career involved 1099 work through locum tenens, travel contracts, or per diem shifts across multiple facilities, your Social Security earnings record may look choppier than a traditional W-2 career. Self-employed CRNAs and NPs pay the full 15.3% self-employment tax, covering both the Social Security and Medicare portions a W-2 employer would otherwise split with you. Lighter income years between contracts still count toward the 35-year earnings history Social Security uses to calculate your benefit, unless you’ve since replaced them with stronger years. Pulling your actual earnings record at ssa.gov before you retire affects both the age-62 and age-70 numbers, so do it early rather than after you’ve already filed.

CRNAs and NPs also have a bridge-income option that a typical retiree doesn’t. Per diem or PRN work can cover spending needs in those early years without touching your portfolio and without formally filing for Social Security. Even 10 to 15 shifts a year at your going rate can cover a meaningful slice of annual spending, reducing how much your portfolio has to carry during the years sequence of returns risk poses the biggest threat. A two or three-year bridge at the start of retirement can change which claiming age makes sense for you.

As an example, consider a hypothetical 60-year-old CRNA retiring after 30 years of hospital anesthesia work, with $2.1 million saved and household spending of about $110,000 a year. This example is illustrative only and doesn’t represent an actual client.

If she claims Social Security at 62, she receives roughly $24,000 a year, leaving $86,000 to pull from her portfolio annually. If she delays to 70, her portfolio has to cover the full $110,000 for eight straight years with no Social Security offsetting anything. Now run a bad market through both paths, say a 15% to 20% decline in year one. In the claim-early path, she withdraws $86,000 from a portfolio that just lost value, painful but manageable. In the delay path, she withdraws the full $110,000, nearly 30% more, from that same shrunken portfolio.

The gap only widens as the years go on. In the claim-early path, her withdrawal rate on the damaged portfolio stays near 4%, because the Social Security check offsets part of the need every year. In the delay path, her withdrawal rate runs much higher with no check to offset anything until age 70, which means more shares sold at depressed prices and fewer shares left to participate when the market recovers. By her late 60s, the two portfolios can look pretty different in size, purely because one path asked more of the portfolio during the years it could least afford to give it.

Delaying comes with its own upside though. By age 70, her Social Security benefit would be about 40% larger for the rest of her life than what she’d have locked in at 62. If she lives well into her 90s, which is increasingly common, the bigger guaranteed check carries more weight the longer she lives. Claiming early protects the fragile early years. Delaying protects the potentially long late years, and there isn’t one correct answer for every CRNA or nurse practitioner. Anyone who tells you otherwise is selling you something simple because complicated is harder to explain.

When I work through this with clients, a few things tend to carry the most weight, including how much of your spending is essential versus flexible, your health and family longevity, whether you have other guaranteed income like a spouse’s pension or a 401(k), and how you’d feel watching your portfolio balance drop in a bad year while collecting nothing from it. Managing your own money is emotional, and that reality deserves as much attention as the math.

If you’re married, your spouse’s situation changes this math too. Social Security’s survivor benefit rules mean the spouse who earns the larger benefit and delays as long as possible sets the number the surviving spouse steps into later. This decision plays out at the household level, and looking only at your own earnings record in isolation can cause you to overlook it.

Some CRNAs and NPs split the difference by claiming at full retirement age. Others use a bridge strategy, picking up PRN shifts for two or three years specifically to delay Social Security. Others claim early on purpose, choosing to keep a larger share of their portfolio invested and compounding rather than needing the income right away.

Before you lock in a claiming age, pull your earnings record from ssa.gov and look for gaps. Then build, or have a financial planner build, a side-by-side comparison of what your portfolio withdrawal looks like at 62, at 67, and at 70, modeling each scenario against a realistic year-one market decline. Look at the dollar gap between the three paths, not just the percentage difference in your monthly check. Consider the bridge income question alongside it.

The bigger question is what job you’re asking Social Security to do inside your broader retirement plan, whether that’s protecting the portfolio during the fragile early years or protecting your income for however long you end up living. Once you know which one you’re solving for, the filing age tends to answer itself.
