‘I nearly made a major misstep’: I claimed my Social Security benefits at 64 instead of 70. Here’s why.
For years I planned to wait until 70 to claim Social Security. The advice is everywhere: every year you delay past full retirement age, your check grows by roughly 8%, plus cost-of-living adjustments. It sounded like a no-brainer—longevity insurance with a government guarantee.
Then I actually ran the numbers for my situation. Waiting reflexively to 70 would have been my misstep. At 64, I filed.
The math I started with
My full retirement age (FRA) is 67. My estimated primary insurance amount (PIA) is $2,650 per month at FRA.
– If I claimed at 64, I’d receive about 80% of my PIA: roughly $2,120 per month.
– If I waited until 70, I’d receive about 124% of my PIA: roughly $3,286 per month.
On paper, that makes waiting look attractive. The age-70 check is about 55% larger than the age-64 check. But benefits I’d collect from 64 to 69 would total roughly $152,000 before I turned 70. The breakeven—how long I’d need to live after 70 for the larger check to catch up—lands around age 81, ignoring taxes and investment returns.
That breakeven age is the pivot. I asked: Given my health, family history, taxes, spouse’s situation, and portfolio, is paying for a bigger check at 70 the best move? It wasn’t.
The reasons I filed at 64
– I’m the lower earner, and my filing unlocked a spousal top-up for my older spouse. My wife is older and already at her FRA. Spousal benefits are based on the worker’s PIA, not what the worker actually receives. She couldn’t receive a spousal top-up until I filed. By filing at 64, I immediately unlocked her spousal amount based on 50% of my PIA. Because I’m the lower earner, my early claim doesn’t reduce the survivor benefit she’d one day rely on; she’ll keep her larger benefit. If I were the higher earner, I’d have thought much harder about waiting to boost her eventual survivor benefit.
– My longevity outlook doesn’t demand a late claim. My parents didn’t make it deep into their 80s, and I have two chronic conditions that, while well managed, realistically lower my odds of crossing the early-80s breakeven. I’m not betting on a short life; I’m acknowledging odds that aren’t as favorable as the averages.
– Portfolio survival mattered more than the “8%” headline. I retired into choppy markets. Early in retirement, the sequence of returns can make or break a plan. Guaranteed income reduces how much I must withdraw from investments when markets are down. Turning on Social Security at 64 lowered my withdrawal rate from about 4.5% to 2.5%. In my planning software, that materially increased my plan’s resilience. If markets are kind, I can dial back later. If they’re not, having more guaranteed income early gives me the flexibility to ride it out.
– I still have a long tax-planning runway. Because of current RMD rules, my required minimum distributions won’t start until 75. I can still convert a slice of pre-tax money to Roth each year, staying under the IRMAA thresholds for Medicare premiums once I enroll at 65. Yes, Social Security adds to “provisional income,” which can make benefits up to 85% taxable and raises AGI for IRMAA. But my benefit at 64 is smaller than it would be at 70, and the reduction in portfolio withdrawals largely offsets it. I also prefer smoothing income over many years rather than stacking a large benefit on top of RMDs later.
– I wanted a secure income floor now. Between my modest pension and Social Security, my essential expenses are covered without touching principal. That let me invest the rest with a calmer stomach and be choosier about when to realize capital gains.
– Flexibility remains. Two safety valves made this choice feel less irreversible. First, if I had changed my mind within 12 months, I could have withdrawn my application, repaid what I received, and reset as if I’d never claimed—once in a lifetime. Second, at my FRA I could suspend benefits and earn delayed retirement credits on my reduced benefit until 70. The early-claim reduction doesn’t disappear, but suspension still boosts the check from that point forward if circumstances change.
What I had to get right
Claiming before FRA isn’t set-and-forget. I checked three key areas first:
– Earnings test. Because I’m under my FRA, if I earn wage income above the annual limit, Social Security withholds $1 for every $2 over the limit (with a different, higher limit and $1-for-$3 withholding in the year I reach FRA). Those withheld months aren’t lost forever—the benefit is adjusted at FRA—but the cash flow timing matters. I dialed my consulting work down to stay under the limit.
– Health insurance timing. Claiming Social Security before 65 doesn’t enroll you in Medicare. Claiming at 65 or later generally triggers Part A enrollment, which has ripple effects if you’re contributing to an HSA. Because I claimed at 64, I avoided the HSA issue. I also verified how my benefit would interact with my pre-Medicare coverage.
– Taxes. I ran multiple scenarios using planning software to understand how Social Security taxation, Roth conversions, capital gains harvesting, and IRMAA thresholds would interact over the next decade. I’d rather adjust conversion amounts than defer Social Security and later stack a larger benefit atop RMDs.
Why the “always wait” mantra didn’t fit me
Rules of thumb are useful; they aren’t rules. The “wait to 70” advice often reflects three big truths:
– The increase from FRA to 70 is valuable longevity insurance, especially for the higher earner in a couple.
– Larger checks mean larger dollar COLAs for life.
– Many retirees underestimate how long they’ll live.
All true. But context matters. In my case:
– I’m not the higher earner, so delaying mine wouldn’t meaningfully help my spouse as a survivor.
– Unlocking her spousal benefit at her FRA required me to file.
– My portfolio and stomach would benefit from a higher guaranteed floor sooner.
– My health and family history lower the odds that I reach the breakeven age where delaying pays off.
– I still have years to manage taxes before RMDs start, and I can aim my Roth conversions at the margins around IRMAA.
What I would tell my past self—and you
– Start with your PIA and run personalized scenarios. Your Social Security statement shows your estimated benefits at different ages. Use a reputable calculator (I used one that optimizes claiming strategies) and then pressure-test the output against taxes, health, and spouse’s benefits.
– Map cash flows. List essential expenses, guaranteed income sources, and likely portfolio withdrawals across the next 10–15 years. Include market downturns in your mental model. If turning on Social Security early meaningfully lowers withdrawals during bad markets, that’s real value.
– Think in terms of household benefits. If you’re the higher earner, delaying often makes sense to raise the survivor benefit. If you’re the lower earner with an older spouse near or at FRA, your filing can unlock a spousal boost sooner. Spousal benefits are based on your PIA, not your reduced amount, and can’t start until you file.
– Respect the breakeven, but don’t obsess over it. It’s a guidepost, not a verdict. Longevity, sequence-of-returns risk, and taxes all push the decision.
– Keep escape hatches in mind. The 12-month withdrawal-and-repay option and FRA suspension offer limited do-overs if life changes.
The bottom line
I didn’t claim early because I don’t value longevity insurance. I claimed because, for our household, the trade-offs favored a smaller check sooner. Filing at 64 unlocked a spousal benefit for my wife, stabilized our withdrawals in a wobbly market, covered our must-have expenses with guaranteed income, and still left me room to manage taxes before RMDs.
The misstep would have been following the crowd to 70 without checking the map for my terrain. Your map will look different. That’s the point.
