Quick Read
Claiming Social Security at 62 instead of 70 can shrink monthly benefits by nearly $1,300, and COLAs compound that gap every year after.
Drawing down a 401(k) between 62 and 70 can fund living expenses while buying a permanently larger, inflation-adjusted Social Security benefit.
For couples, the higher earner’s claiming age can cap the survivor benefit, making the decision far more consequential than a solo break-even calculation.

The Instinct That Feels Responsible
Picture a 62-year-old with a healthy 401(k), a paid-off house, and an old financial-planning rule ringing in his ears: never spend principal. He needs income. Social Security is available, while the 401(k) feels untouchable. He files early and lets the smaller monthly check cover the gap. That instinct is common.

A Corebridge Financial survey found that only 28% of respondents felt comfortable watching their retirement savings decline to cover living expenses, while 70% considered preserving the nest egg very important. On retirement forums, people in their early 60s describe the same tension. They have enough saved but cannot bring themselves to watch the balance fall.
The reflex feels disciplined. It can also lock in a permanently smaller inflation-adjusted benefit and potentially reduce what a surviving spouse receives later.
What Claiming at 62 Actually Costs
Social Security uses two main ingredients to set the monthly check: a worker’s earnings history and claiming age. For someone with a full retirement age (FRA) of 67, claiming at 62 reduces the benefit by approximately 30%. Waiting beyond 67 adds delayed retirement credits of about 8% a year until 70.

What’s Your Number…?
Here’s a question most people 5y from retirement can’t answer: at your current savings rate, how much do you need, and how long will it actually last? A good advisor can put a date on that in a single meeting.

Consider a worker whose full benefit at 67 would be $2,400 a month. Filing at 62 shrinks it to approximately $1,680. Waiting until age 70 raises it to about $2,976. The difference between those two checks is nearly $1,300 a month. That does not make waiting free. He must replace eight years of benefits between 62 and 70 using savings, work, a spouse’s income, or some combination. The question is whether spending part of the 401(k) during those years buys enough additional lifetime Social Security income to justify the withdrawal.
Story Continues
Cost-of-living adjustments (COLAs) widen the dollar gap. With a 2.8% COLA, a $1,680 check gains about $47 a month. A $2,976 check gains approximately $83. The same percentage keeps landing on two very different bases. The survivor calculation raises the stakes for couples. If the higher earner dies first, the surviving spouse can generally receive the higher of the two household benefits, not both. The worker’s early claim can limit that survivor payment. Delayed retirement credits can increase it. The survivor’s own claiming age also affects the amount received.

Why the 401(k) Bridge Is Worth Considering
For someone with sufficient savings, the logic can be reversed. Drawing from the 401(k) between 62 and 67 or 70 may buy a permanently larger, inflation-adjusted Social Security benefit. The account balance falls during the bridge years, but the money is not disappearing without purpose. It is financing retirement, which is why the account exists. In exchange, the household receives a larger lifetime income stream that does not rise and fall with the stock market.
That trade still carries risk. Traditional 401(k) withdrawals are taxable, and selling investments during a market decline can damage a portfolio. Someone in poor health or without enough savings to withstand a prolonged downturn may be better served by claiming earlier. The bridge should be modeled, not treated as another universal rule.
What to Work Through Before Filing
Three questions matter most:
Run the survivor calculation. If one spouse is likely to depend on the higher earner’s benefit for many years, that person’s claiming age may matter more than an individual break-even calculation.
Price the bridge after taxes. Estimate the 401(k) withdrawals required, the income tax they create, and the balance remaining under weak-market scenarios. Compare that with the monthly Social Security benefit available at 62, 67, and 70.
Separate discomfort from danger. Watching a retirement account decline can feel like something has gone wrong. A planned drawdown that purchases a larger lifetime benefit is different from uncontrolled spending.
Never spend principal can be a useful guardrail. It is not a hard fast rule. Retirement savings are not a museum exhibit meant to remain untouched. For the right household, spending some of the 401(k) first may be exactly what protects the income that must last the longest.
