Social Security Spousal Benefits Can Add Up to $10,000 a Year. Most Couples Never Claim Them Correctly

Most married couples think about Social Security as two separate decisions. Each spouse files when the time feels right, takes whatever the annual statement projects, and moves on. What gets left on the table is often substantial. For couples who understand how spousal benefits interact with their own claiming strategy, the difference between an uninformed decision and a well-timed one can add up to tens of thousands of dollars over a retirement that lasts two decades or more.

The mechanics of the spousal benefit are simpler than most people assume. A qualifying spouse can receive up to 50% of the other spouse’s primary insurance amount, which is the benefit the higher earner would receive at their full retirement age. The structure sounds straightforward, but the details are where most couples go wrong.

The critical distinction is that spousal benefits do not grow by delaying past full retirement age. A spouse who waits until 70 to claim a spousal benefit receives exactly the same amount as one who claimed at full retirement age. The incentive structure for each type of benefit is completely different, and most couples never learn this until it is too late to act on it.

The Basics Most Couples Miss

To receive a spousal benefit, the claiming spouse must be at least 62, and the primary earner must have already filed for their own benefit. Social Security pays the higher of the two amounts, either the claimant’s own earned benefit or the spousal benefit, never both simultaneously.

A spouse with no work history, or a limited one, can receive up to 50% of the higher earner’s full retirement age benefit. That is an income stream they would otherwise not have access to on their own, and for many households it represents a meaningful addition to monthly retirement income.

Claiming a spousal benefit before full retirement age reduces it permanently. A spouse who claims at 62 instead of waiting until full retirement age can see that benefit cut by as much as 35%, leaving them with 32.5% of the higher earner’s primary insurance amount rather than the full 50%. The reduction is locked in for life, which makes the timing decision far more consequential than many couples in their early 60s realize.

One important development worth noting: the Social Security Fairness Act, signed into law on January 5, 2025, repealed the Government Pension Offset and the Windfall Elimination Provision. Before that change, public-sector workers collecting government pensions often had their spousal benefits reduced or eliminated entirely. The repeal opened full spousal benefit access to roughly 2.8 million teachers, firefighters, police officers, and federal employees who had been partially or fully shut out of these payments.

Why the Coordination Strategy Is the Real Opportunity

For most married couples, the bigger opportunity is not the spousal benefit in isolation. It is the coordination of two claiming decisions to maximize combined household income across the full retirement period.

The strategy financial planners return to most consistently is this: the lower-earning spouse claims earlier, often at or near full retirement age, while the higher-earning spouse delays as long as possible, ideally until 70. The lower earner’s claim activates the spousal benefit pathway and generates income while the higher earner’s benefit continues to grow. Both things happen at once.

The higher earner’s benefit increases by roughly 8% for each year of delay past full retirement age, meaning waiting from 67 to 70 can increase that benefit by 24% before inflation adjustments. When both strategies are executed well, the combined household monthly income can reach levels that surprise couples who never ran the numbers.

The average retired worker currently receives approximately $2,086 per month from Social Security, according to the SSA’s July 2026 Monthly Statistical Snapshot. For a household where both spouses each collect the average benefit, that works out to roughly $4,172 combined. The SSA’s own COLA fact sheet shows the actual average for an aged couple (where one spouse may be collecting a spousal benefit rather than a full worker benefit) is closer to $3,208 per month, which illustrates how much the spousal benefit gap can cost households that never optimized. Couples where both spouses have strong earnings records and both claim optimally can approach a combined monthly income well above that, with the absolute ceiling for a couple in 2026 sitting at $10,362 if both spouses each qualify for the maximum individual benefit of $5,181 per month.

That ceiling is available to a very small share of households. But the directional lesson applies broadly: the gap between an uninformed strategy and a coordinated one is far larger than most couples expect.

The 35-Year Earnings Record Problem

One reason more couples do not reach higher benefit levels is how Social Security calculates the primary insurance amount. The benefit is based on the 35 highest-earning years in a worker’s record, adjusted for wage inflation. Fewer than 35 years of earnings means Social Security fills the remaining slots with zeros, which drags the average down substantially.

For a spouse with a shorter or interrupted work history, this can produce an own benefit low enough that the spousal benefit becomes the better option by default. For the higher earner, gap years from early retirement, caregiving, or career interruptions carry a lasting cost, because those are the years that determine the benefit the household will eventually rely on most.

Getting the Timing Right

The lower-earning spouse can often claim earlier because their benefit calculation matters less to the long-term household outcome. The higher earner’s benefit, by contrast, should be treated as a longevity asset: the income stream that matters most if one spouse outlives the other by a significant margin.

Survivor benefits add another dimension to this. When one spouse dies, the surviving spouse steps up to the higher of the two benefits. That means a higher earner’s delayed benefit provides permanent income protection for whoever lives longer. Delaying to 70 is not only about income while both spouses are alive. It is also about building the largest possible financial floor for the surviving spouse.

Running the actual numbers with a Social Security calculator or a financial planner before making any filing decision is well worth the time. The choices couples make in this window are largely irreversible, and the stakes are high enough that a few hours of planning can produce a materially better outcome for the next 20 or 30 years.

Editor’s note: This article has been updated to reflect the SSA’s July 2026 average retired-worker benefit of $2,086 per month (revised from $2,078), to add the SSA-reported aged-couple average of $3,208 per month and the 2026 maximum combined couple benefit of $10,362 per month, and to incorporate context on the Social Security Fairness Act signed January 5, 2025, which repealed the Government Pension Offset and restored full spousal benefit access to approximately 2.8 million public-sector workers.
