Retirement’s Quiet Wealth Gap: Single Older Adults Lag Far Behind Couples by $321,000

Two retirees can divide the mortgage, utility bills, and even the financial burden tied to Social Security. A person living alone has no one to share those costs, and that difference can reshape the way retirement needs to be planned.

Retirement is meant to reward years of work, saving, and sacrifice. In practice, though, the quality of those years can hinge on a factor that many retirement calculators barely address: whether someone is married or single.

When two people share a household, they can split housing expenses, utilities, and other routine costs. A solo retiree pays many of those same bills alone. Social Security helps provide a base level of income, but it does not fully erase the gap.

Recent retirement wealth data show how large that divide has become. The difference between single seniors and married or partnered retirees now tops $321,000.

A $321,000 Retirement Wealth Divide

The numbers are stark. Median non-housing wealth varies sharply based on whether older adults live alone or with a spouse or partner.

Married or partnered seniors have about 7.4 times the median non-housing wealth of single seniors.

Non-housing wealth matters because it reflects assets outside the value of a primary residence. Home equity can support retirement, but it usually cannot cover day-to-day expenses unless it is borrowed against, sold, or otherwise turned into cash.

The median is also revealing. Unlike an average, which can be lifted by a small number of very wealthy households, the median shows the midpoint of the distribution.

Still, these figures compare different household types rather than two identical retirees. Couples often bring two earnings histories and more years of saving to the table. The data do not prove that marriage itself causes the gap.

Even so, the findings underscore a retirement planning problem that becomes harder to ignore as living costs continue to rise.

Why Living Alone Costs More in Retirement

The disadvantage is not limited to smaller nest eggs. Housing is a major example. A married couple paying $1,800 a month for housing effectively splits a $21,600 yearly cost. A single retiree in the same home carries the full amount. Property taxes, homeowners insurance, and heating bills do not fall by half simply because one person is gone.

Social Security can also add to the challenge. Married couples may receive two retirement benefits, while a surviving spouse generally gets the larger applicable benefit instead of continuing to collect both payments.

Even the 3.6% Social Security cost-of-living adjustment for 2027 does not remove that imbalance. A retiree receiving $2,000 a month would get a $72 increase, no matter how much household expenses may have climbed.

The savings gap goes beyond account balances, too. An analysis of Federal Reserve Survey of Consumer Finances data found that only 34.8% of single older households owned a retirement account, compared with 59.5% of married or partnered households.

That leaves more single seniors relying on Social Security, pensions, or savings held outside retirement accounts.

How Single Retirees Can Strengthen Their Finances

The wealth divide does not mean single Americans are bound to struggle financially. It means retirement planning has to account for the loss of a second income and the absence of shared household expenses.

Workers nearing retirement should build budgets around one income rather than assuming spending will fall proportionally if household circumstances change.

Social Security claiming decisions also deserve close attention. For those eligible for delayed retirement credits, postponing benefits past full retirement age increases the monthly payment by 8% a year until age 70.

Additional savings become especially important if future Social Security benefit cuts create a $500 monthly income gap. Filling that shortfall could require about $150,000 in extra savings, based on a 4% annual withdrawal rate.

For retirees already living alone, housing should be reviewed carefully. Downsizing or moving can lower recurring expenses while potentially unlocking home equity.

Widowed retirees should also understand how survivor benefits can help replace income after a spouse dies. Eligibility and payment amounts depend on the deceased spouse’s earnings record and other claiming rules.

The Bottom Line

The $321,000 retirement wealth gap highlights a reality that standard retirement advice often misses: retirement costs more when there is no second person to help pay the bills.

Couples may have larger combined savings, two earnings histories, and the ability to split fixed costs. Single retirees often have fewer resources supporting many of the same expenses.

The lesson is not that marriage guarantees financial security. It is that retirement plans need to work even if only one person is left to cover the costs. For anyone approaching retirement, preparing for that possibility may matter just as much as reaching a savings target.
