| Monthly benefit (born 1960 or later) | About 70% of the full-retirement-age amount, reduced permanently | 100% of the full-retirement-age amount | 124% of the full-retirement-age amount, with no further increase after 70 |
| Number of payments | More payments, each smaller | The reference point | Fewer payments, each larger |
| Simple break-even age | Cumulative payments from a 67 claim pass a 62 claim at about 79 | The reference point | Cumulative payments from a 70 claim pass a 67 claim at about 82 to 83 |
| Working while collecting (2026) | Earnings test: $1 withheld for every $2 earned above $24,480 | No earnings limit from the month you reach full retirement age. In the year you reach it, $1 is withheld for every $3 earned above $65,160 in earlier months | No earnings limit |
| Spouse's benefit, claimed on a partner's record | Reduced: 32.5% of the worker's unreduced benefit when full retirement age is 67 | Up to 50% of the worker's full-retirement-age amount | Does not rise above 50% after full retirement age, and the worker's delayed credits do not raise it |
| Survivor benefit | A survivor's benefit is based on the worker's record, so an early claim may lower the amount a survivor can receive | A survivor at full survivor retirement age generally gets 100% of the worker's basic benefit amount | Delayed retirement credits the worker earned are included in the survivor's amount |
| Taxes on benefits | Benefit income starts sooner and may overlap with wages or withdrawals; up to 85% may be taxable | Benefit income begins at 67; up to 85% may be taxable above the IRS thresholds | Years before 70 may have no benefit income; the larger benefit may be taxed up to 85% once it starts |
| Years funded by other sources | The fewest years to cover from savings, wages or other income | Savings, wages or other income cover the years until 67 | The longest gap, which other income may need to cover and which could add taxable income |
| May fit when | Income is needed sooner, other sources are limited, or health or family history points to a shorter horizon | A household wants the unreduced benefit without a longer wait | Other sources can fund the wait and a larger benefit for a surviving spouse is a priority |
