When to claim Social Security: how your age changes the benefit

Basics10 min read · updated 2 November 2026 · 9 sources

Deciding when to claim Social Security is one of the largest financial decisions of retirement. You can start at any age from 62 to 70, and each year of waiting raises the monthly check for the rest of your life. Because benefits also rise with inflation every year, the difference adds up to a large amount over a long retirement. This article explains the rules for 2026, why the popular break-even calculation answers the wrong question, what changes for married couples and when claiming early still makes sense.

How your claiming age changes the benefit

Your benefit starts from your primary insurance amount, the monthly benefit at full retirement age. For anyone born in 1960 or later, that age is 67 (SSA, Retirement Benefits 2026). Claiming earlier reduces the benefit permanently: by 5/9 of 1% for each of the first 36 months before full retirement age and by 5/12 of 1% for each additional month, so claiming at 62 costs 30% (SSA, early or late retirement 2026). Waiting beyond full retirement age earns delayed retirement credits of 8% for each full year, until age 70 (SSA, Retirement Benefits 2026).

The table shows the result for a full benefit of $2,000 a month, close to the average retired worker benefit of $2,071 in January 2026 (SSA, COLA fact sheet 2025). Waiting from 62 to 70 raises the monthly check by more than three quarters.

Every benefit, whenever it starts, rises each year with the cost-of-living adjustment, 2.8% for 2026 (SSA, COLA fact sheet 2025). The percentage gap between early and late claiming therefore stays the same in today's dollars for life. The maximum benefit for a worker retiring at full retirement age in 2026 is $4,152 a month (SSA, COLA fact sheet 2025).

The break-even age and why it misleads

The most common way to compare claiming ages is the break-even age: from when on has the person who waited collected more in total than the person who started early?

The break-even view treats Social Security like an investment that has to pay off. It is better understood as insurance: a lifelong annuity, protected against inflation, that pays the most exactly when money is most likely to run short, in a long life. Dying early is not a financial problem for the person who dies; outliving one's savings is. Seen that way, a larger check from 70 is protection against the expensive scenario.

How the choice is presented has a large effect. In a survey experiment with about 3,000 households, Brown et al. (2011) found that people shown a break-even explanation planned to claim about 15 months earlier than people shown a neutral one, although the rules were the same. Shoven and Slavov (2014) calculate the value of delaying for different households: at low real interest rates, delaying is worthwhile for many people, even with mortality about twice the average. Only single people with clearly above-average mortality do not gain once interest rates are closer to their historical average.

Married couples and survivor benefits

For couples, the decision of the higher earner matters most. A spouse with little or no earnings can receive up to half of the worker's full benefit, at most at the spouse's own full retirement age (SSA, Retirement Benefits 2026). When one spouse dies, the survivor keeps the larger of the two benefits: a surviving spouse at full retirement age can get up to 100% of the deceased worker's benefit (SSA, survivor benefits 2025), and a widow or widower receives the increase from the delayed retirement credits the deceased spouse had earned (SSA Handbook § 720 2026).

Waiting by the higher earner therefore raises two checks: their own and, potentially, the survivor's for the rest of the survivor's life. With a full benefit of $3,000 a month, claiming at 70 instead of 62 lifts the higher earner's benefit from $2,100 to $3,720 a month, and that larger amount is what can continue to the surviving spouse. A common approach is for the lower earner to claim earlier and the higher earner to wait.

Working while claiming: the earnings test

If you claim before full retirement age and keep working, the retirement earnings test can hold back part of your benefit. In 2026, $1 is withheld for every $2 earned above $24,480 a year. In the calendar year you reach full retirement age, the limit is $65,160 and $1 is withheld for every $3 above it, counting only earnings before the month you reach that age. From full retirement age on, there is no limit (SSA, COLA fact sheet 2025).

Taxes on benefits

Up to 85% of Social Security benefits can be subject to federal income tax. The test uses provisional income: adjusted gross income plus tax-exempt interest plus half of the benefits. For married couples filing jointly, up to 50% of benefits become taxable above $32,000 of provisional income and up to 85% above $44,000; for single filers, the thresholds are $25,000 and $34,000. None of these amounts is adjusted for inflation (CRS, taxation of Social Security 2025).

For 2025 to 2028, taxpayers aged 65 or older can also take an extra deduction of $6,000 each. It phases out by 6% of modified adjusted gross income above $75,000 for single filers and $150,000 for joint filers, and it does not change how much of the benefits counts as taxable (CRS, taxation of Social Security 2025).

When claiming early makes sense

• Poor health or a short life expectancy: for single people with clearly above-average mortality, waiting does not pay (Shoven and Slavov 2014).
• No other money to bridge the gap: if the only alternative is high-interest debt, an early check is better than borrowing.
• The lower earner in a couple: an earlier claim by the spouse with the smaller benefit costs less, because the larger benefit is the one that continues to the survivor.
• Larger savings than needed: for households whose portfolio comfortably covers spending, the insurance value of a larger check matters less.

Waiting is not free either. Someone who retires at 62 and delays the claim to 70 has to live on savings for eight years. Drawing a larger share from the portfolio early in retirement raises the sequence risk of a market crash in those years, which is why the decision belongs in the same plan as the withdrawal rate.

The trust fund question

Many people claim early because they worry the program will run out of money. According to the 2026 Trustees Report, the reserves of the retirement trust fund (OASI) are projected to be depleted in 2032; after that, ongoing payroll tax income would still cover 78% of scheduled retirement benefits unless Congress acts (Trustees Report 2026). A shortfall would affect all benefits being paid at that time, not only new claims, so claiming early does not protect against it. For planning, it can make sense to test a retirement plan with a lower benefit as a stress scenario.

Medicare follows its own schedule. Even if you delay Social Security, you should contact the Social Security Administration at least three months before your 65th birthday to sign up for Medicare and avoid late enrollment penalties (SSA, Retirement Benefits 2026).

Common mistakes

• Deciding by break-even age alone: the larger risk is a long life, and the bigger check insures against it.
• Claiming early while working full time: the earnings test withholds benefits, and the reduction for claiming early is permanent.
• Ignoring the survivor: in a couple, the higher earner's age at claiming sets the benefit that can continue for the surviving spouse.
• Claiming out of fear of insolvency: a funding gap would reduce all benefits, including those already being paid.
• Forgetting taxes: IRA withdrawals on top of benefits can make up to 85% of the benefits taxable.
