Many people in the U.S. are nearing retirement with 401(k) accounts that are too small. If you're one of them, you may want to add as much extra money as you can to your plan, but it can be hard to make a meaningful impact on your balance when you're in your 60s already.
The good news is, you can make a Social Security move that's roughly the equivalent of adding $144,000 to your 401(k) -- and you can do it right when you reach your retirement age. Here's what you need to do.

The Social Security choice that you need to make is very straightforward. You need to wait beyond your full retirement age and claim benefits at 70 instead.
Say, for example, you were born in 1960 or later, and your FRA is 67. If you were on track for a standard benefit of around $2,000 (pretty close to the average for 2026), you could increase your benefit by 8% per year if you waited until 70 to claim it. That's thanks to delayed retirement credits worth 2/3 of 1% per month.
In this case, a 24% benefit bump is worth $480 per month, or $5,760 per year.
To generate that much money with a 401(k), assuming you follow the 4% rule, you would need to put an extra $144,000 into your retirement plan.
Delaying a Social Security claim until 70 can clearly have a pretty big impact on your monthly benefit. Studies have also shown that it gives you the best chance of maxing out your lifetime benefits.
That's because the system of early-filing penalties and delayed retirement credits was put in place to equalize benefits for early and late claimants, but life expectancies have increased since it was created.
Of course, you'll either need to work until 70 to pull off this plan or have enough money in your retirement accounts to support you until you claim benefits at 70. Investing as much as you can in your IRA, 401(k), and other retirement accounts during your working life can make that possible.
Putting off the time until you retire can also give you more time to save and invest, and it means you'll have to rely on your savings for fewer years. You can have a much more secure retirement for all of these reasons.
So, if you want the equivalent of a $144,000 401(k) boost, you should seriously consider putting off your claim. When you have more financial security in your later years, you'll be glad you did.
If you're like most Americans, you're a few years (or more) behind on your retirement savings. But a handful of little-known "Social Security secrets" could help ensure a boost in your retirement income.
One easy trick could pay you as much as $23,760 more... each year! Once you learn how to maximize your Social Security benefits, we think you could retire confidently with the peace of mind we're all after. Join Stock Advisor to learn more about these strategies.

Four leading AI models discuss this article
"The $144,000 equivalence glosses over liquidity shortfalls and longevity risk that make the strategy unsuitable for most retirees lacking substantial savings."
Delaying Social Security to 70 for delayed retirement credits can raise a $2,000 FRA benefit by 24 percent to $2,480 monthly, matching the income from an extra $144,000 in a 401(k) at the 4 percent rule. Yet this equivalence assumes retirees can self-fund or work three extra years without drawing down savings at higher rates, ignores sequence-of-returns risk during the bridge period, and treats the higher benefit as risk-free when early mortality before roughly age 82 leaves the claimant with permanently lower lifetime payouts than claiming at FRA.
Longevity has risen since the credit formula was set, and COLA-adjusted lifetime benefits for survivors often exceed what could be safely withdrawn from an equivalent lump sum invested in equities.
"Delaying Social Security to 70 can improve lifetime retirement cash flow, but its value is highly conditional on longevity, taxes, and investment assumptions, not a universal $144k gain."
Delaying Social Security to age 70 can boost lifetime cash flow, and the math behind the $144,000 ‘equivalent’ of a larger 401(k) is plausible in a narrow set of conditions. But the article glosses over crucial frictions: taxes on Social Security benefits, rising Medicare premiums with higher income, and longevity risk (the plan only pays off if you live long enough). It also relies on the 4% withdrawal rule, which is under debate in today’s low-yield environment, and ignores survivor benefits and other liquidity needs. The promotional framing (including the $23,760 hook) may mislead readers about how robust this strategy is across different households.
If you don’t live long enough to reach age 70, or if health costs and taxes erode the boosted SSA income, the supposed $144k gain vanishes; and the reliance on a fixed withdrawal rule may misprice longevity risk.
"The 'equivalent of $144,000' is a theoretical actuarial value that ignores the high opportunity cost of liquidity and the risk of premature death."
The article correctly highlights the mathematical benefit of delayed Social Security filing, but it ignores the 'longevity risk' and liquidity constraints. While an 8% annual increase in benefits is effectively a guaranteed, inflation-adjusted annuity, it requires an individual to have sufficient bridge capital to survive from age 67 to 70. For the median household with under $100,000 in liquid retirement assets, this strategy is mathematically sound but practically impossible. Furthermore, it assumes the Social Security trust fund remains solvent without legislative benefit cuts, a significant tail risk for those betting their entire retirement strategy on government-backed payouts versus private market equity growth.
The primary risk is mortality; if an individual dies at 72, they have forfeited three years of benefits and effectively lost their 'investment' in delayed credits compared to someone who claimed early.
"The article presents a mathematically correct but behaviorally irrelevant strategy for the underfunded retirees it claims to help, since those with inadequate 401(k)s typically cannot afford to work until 70."
The article conflates two separate financial decisions—401(k) adequacy and Social Security timing—to create a false equivalence. Yes, delaying SS from 67 to 70 increases annual benefits by ~$5,760 (24% bump), and yes, a 4% withdrawal rule means you'd need $144k invested to generate that. But this ignores critical variables: mortality risk (breakeven is ~80-82), sequence-of-returns risk during the delay period, and opportunity cost of working three extra years. The $23,760 'bonus' teaser is clickbait masking spousal/survivor benefit strategies that require specific household structures. Most underfunded retirees can't afford to delay—they need income now, not a theoretical 20-year payoff.
If you live to 90+, delaying IS actuarially optimal and the $144k equivalence is mathematically sound; the article correctly identifies that life expectancy gains since 1983 favor late claiming.
"The 401(k) equivalent retains bequest potential that the SS annuity lacks, a distinction the panel has not addressed."
Claude flags the false equivalence well, but both the $144k 401(k) lump sum and enhanced SS benefit overlook legacy value: the account balance can be bequeathed or tapped for long-term care, while delayed credits produce no residual estate beyond limited survivor options. This tilts the math against delay for households focused on intergenerational transfers rather than pure personal income replacement.
"Delaying Social Security is not robust for many households because policy and cost dynamics—COLA, Medicare premiums, and potential legislative changes—can erode the breakeven advantage, making the 80–82-year horizon a moving target, particularly for couples and survivor scenarios."
Claude’s emphasis on mortality and delay cost is valid, but the bigger overlooked risk is policy and cost dynamics that can erase the net gain. If COLA, Medicare Part B premiums, or potential Social Security tweaks outpace the assumed 24% bump, the lifetime value of delaying can shrink fast for many households. The breakeven to 80–82, and beyond for longer lifespans, becomes a moving target, especially for couples and survivors relying on Social Security alone.
"Legislative solvency measures, such as future benefit means-testing, represent a systemic risk to the 'guaranteed' return of delayed Social Security credits."
Gemini’s focus on trust fund solvency is the elephant in the room. While everyone debates individual breakeven points, we are ignoring the structural risk of legislative 'means-testing' for high-earners. If Congress pivots to solvency via benefit clawbacks for those with other assets, the 'guaranteed' 8% annual delay credit becomes a target for taxation or reduction. Betting on a 20-year horizon for Social Security is an unpriced policy risk that dwarfs the standard mortality calculations discussed here.
"Means-testing is a 20-year tail risk; inflation and healthcare cost acceleration are 5-year headwinds that matter more for breakeven math."
Gemini's means-testing risk is real, but the timeline matters enormously. Legislative clawbacks typically grandfather existing beneficiaries or phase in slowly—anyone claiming at 70 in 2035 likely locks in current rules. The *actual* unpriced risk is earlier: if inflation erodes real purchasing power of the 24% bump faster than COLA adjusts, or if healthcare costs spike before age 82, the breakeven shifts left. We're debating policy tail risk while ignoring the near-term erosion of the nominal gain.
Delaying Social Security to 70 may not be beneficial for most retirees due to risks like sequence-of-returns, longevity, and policy changes. It's more suitable for those with sufficient bridge capital and long lifespans.
