Social Security claiming decisions can materially change retirement income, with the timing of when beneficiaries start collecting playing a central role. For people eligible for a full retirement age of 67, claiming before that age reduces monthly benefits, while delaying past full retirement age increases them until age 70—creating different break-even points that can determine which strategy delivers more lifetime income.
According to research cited by The Motley Fool, benefits can rise by roughly 8% per year when workers delay claims after full retirement age, reaching a maximum increase if benefits are claimed at age 70. The piece also highlights that life expectancy data implies many retirees live beyond their calculated break-even ages, making late claiming advantageous for those able to wait.
Key takeaways
- Benefit levels move with claiming age: claiming earlier than full retirement age reduces the primary insurance amount.
- Largest increases come from delay: delaying benefits after full retirement age boosts the primary insurance amount by about 8% annually up to age 70.
- Break-even matters: the break-even age is when lifetime benefits from two claiming choices are roughly equal.
- Most may clear break-even: Social Security life expectancy data indicates many people live past their break-even ages.
How your claiming age affects benefits
For individuals born in 1960 or later, full retirement age is 67. Claiming before full retirement age lowers the baseline benefit, known as the “primary insurance amount,” with the reduction tied to how far the claim is moved earlier.
- Claiming at 66: 6.7% reduction
- Claiming at 65: 13.3% reduction
- Claiming at 64: 20% reduction
- Claiming at 63: 25% reduction
- Claiming at 62: 30% reduction
Delaying claims after full retirement age increases the primary insurance amount. The article explains the formula as 2/3 of 1% per month, which totals to an 8% annual increase. It also notes that waiting until age 70 can raise benefits by 24% relative to claiming at full retirement age.
After age 70, benefits no longer increase under the Social Security rules described in the article, which is why age 70 is commonly treated as the latest claiming age for maximizing monthly benefit growth.
What the research suggests about the “best” age
According to the article, a study by the National Bureau of Economic Research (NBER) concludes that 70 is the best claiming age because it allows for higher lifetime benefits. The underlying logic is that earlier claiming generally pays more in the near term, but later claiming can produce a larger monthly benefit stream that may outweigh the lost payments if the retiree lives long enough.
The article provides example break-even calculations to illustrate the trade-off. For a person comparing claims at 62 versus 70, the break-even age is estimated at around 80.3 years old. Under that framework, the earlier claimant receives more total lifetime benefits up to the break-even point, while the later claimant benefits after.
For a second comparison—claiming at 67 versus 70—the article estimates the break-even age at 82.5. It argues that if most beneficiaries live beyond these thresholds, claiming at age 70 tends to maximize lifetime income.
Why personal circumstances can override the data
Although the research-based approach points toward later claiming for maximizing lifetime benefits, the article stresses that there is no one-size-fits-all answer. It lists practical constraints that can make waiting less feasible for some retirees, including the need for Social Security as an income source when other savings or assets are insufficient.
Health and longevity risk is another key factor. If medical circumstances reduce the probability of reaching the break-even age, the expected advantage of waiting can shrink. The article also notes that some retirees prioritize earlier cash flow rather than maximizing total lifetime benefits.
Additionally, the piece highlights that strategies depend on whether beneficiaries have alternative retirement income streams—such as a 401(k), IRA, or a pension. In that context, it states that only about 1 in 10 people choose to wait, according to the same NBER study referenced in the article.
What to watch next
For retirees and pre-retirees making claiming decisions, the next step is to align the claiming age with expected cash-flow needs and personal longevity. Investors and households approaching retirement may want to track upcoming Social Security-related policy developments, while also planning around retirement account withdrawals and other income sources to determine whether delaying claims to 70 is financially practical. The decision remains time-sensitive, since the optimal claiming age can change as health, savings, and household circumstances evolve.
