The generation now retiring holds more wealth than any before it, and a larger share of it arrives at retirement still owing money. Both things are true, and the second is the one that changes how the first has to be managed.

The data, and its vintage

More than half of households headed by someone aged 75 or older carried debt in 2022, up from 41.3% a decade earlier, on the Federal Reserve's Survey of Consumer Finances. That survey runs every three years and is published with a lag, so the most recent full picture is four years old. Treat it as a description of a trend rather than of today.

Mortgages are the bulk of it. AARP's analysis of New York Fed data puts mortgage debt at roughly three-quarters of what Americans aged 70 and over owe, with the median balance among older mortgage holders having risen from $16,793 to $72,000 across recent decades, and the share of homeowners aged 65 to 79 with a mortgage up 17% since 1989.

Credit cards are the second thread. AARP reports 42% of people aged 65 to 74 and 35% of those 75 and over carrying credit card balances, with nearly half of those who carry a balance owing $5,000 or more.

Some of the newer borrowing is deliberate rather than distressed: about 57% of home equity lines of credit originated in 2023 and 2024 went to borrowers aged 50 and over.

Why fixed debt against fixed income is the specific problem

A working household absorbs a bad month by working. That option narrows in retirement, and the arithmetic changes with it.

Social Security is indexed to inflation through the annual cost-of-living adjustment, but the adjustment follows a measured price index and arrives after the fact, so a household absorbs the gap in the meantime. A mortgage payment does not adjust at all, which cuts the other way and is the reason fixed-rate debt is often described as an inflation hedge for the borrower.

The problem is not the direction of either effect. It is that debt service converts a flexible expense into a fixed one at exactly the point in life when the other fixed costs, principally health care, are rising and least predictable.

What it does to a withdrawal plan

The clearest way to see it is with a worked example, and the assumptions matter as much as the answer.

Take a household with $500,000 in a retirement account, drawing 4% a year, which is $20,000. Say the mortgage payment is $1,500 a month, or $18,000 a year, in principal and interest. On those numbers the portfolio withdrawal covers the mortgage and little else, and everything discretionary has to come out of Social Security.

Now add a market fall in the first years of retirement. Selling assets to make fixed payments while prices are down means selling more units to raise the same dollars, and those units are not there to recover when the market does. Advisers call this sequence-of-returns risk, and fixed debt service makes it worse because it removes the option of simply spending less that year.

None of that makes carrying a mortgage into retirement wrong. A 3% mortgage held against a portfolio earning more than 3% is a rational position, and paying it off early converts a liquid asset into an illiquid one. The point is that the two decisions are linked, and the arithmetic depends on the rate, the balance, the portfolio and the household's tolerance for selling into a fall.

The distinction that actually matters

Not all of this debt is the same thing. A low-rate mortgage on a house worth several times the balance is a financing choice. A credit card balance at a rate in the high teens or twenties is a drain that compounds against a household with no way to earn more.

The wealth numbers make the aggregate look comfortable, and in aggregate it is. Aggregates conceal distributions, and a median that looks fine is consistent with a substantial minority for whom debt service consumes a share of fixed income that leaves nothing for the year the roof or the diagnosis arrives.

This is reporting on what the data shows, not advice on what any household should do. Anyone weighing whether to carry a mortgage into retirement is weighing their own rate, their own portfolio and their own tolerance for a bad market in the wrong year, and no general figure settles that.
