The money parents plan to leave behind will most likely arrive two full decades after financial pressure peaks.

Vanguard analyzed 250,000 401(k) participants and 57,956 inherited Individual Retirement Account (IRA) recipients in its research paper, “Transferring Wealth with Wisdom.”

The debt-to-income analysis drew on data including income, age, and linked credit bureau data for 2023, according to the paper’s methodology notes.

The findings show what happens when the peak years of household borrowing and family wealth transfers land in different decades of life. Participants in their forties had an average debt-to-income ratio of 29%, nearly triple the 9% reported by those in their 20s.

Inherited IRAs land well after the most expensive years

Household debt-to-income ratios tend to peak between ages 30 and 49, according to the Vanguard data, when mortgages, childcare, student loans, and retirement contributions compete for the same dollars.

Fully 97% of inheritance recipients in the study receive the transferred assets only after the grantor passes away, Vanguard’s research found.

That timing places the typical transfer in a beneficiary’s early 60s, well past the window when additional capital would have its strongest compounding effect.

The benefits of an inheritance hinge on timing and the recipient’s balance sheet, Ekaterina Goncharova, PhD, a Behavioral Economist at Vanguard and the lead author of the paper, noted.

Matt Schulz, Chief Consumer Analyst at LendingTree and author of Ask Questions, Save Money, Make More: How To Take Control Of Your Financial Life, wrote in an August 2026 LendungTree wealth transfer study that households should build retirement plans that work without a family windfall.

<strong>A future inheritance should generally be treated as a potential upside rather than a core retirement strategy. Build a retirement plan that works without it, and if an inheritance ultimately materializes, it can improve your financial security rather than rescue it,</strong>

Inherited IRAs boosted investable assets by about 66% for recipients in their thirties but only 22% for those in their sixties, the firm’s data showed. 

IRA recipients owe $35,000 more than they inherit

Among IRA recipients in the Vanguard research, 54% had outstanding balances when they received the assets, and the average debt exceeded the inheritance by $35,000.

The total liabilities included mortgages, auto loans, student loans, and revolving credit card accounts, totaling $141,000, compared with a $106,000 inherited IRA balance.

The paper found that many recipients evaluate the windfall in isolation from their outstanding liabilities. 

Malena de la Fuente, a Behavioral Scientist and Economist at Vanguard and the paper’s coauthor, said the team “were surprised that heirs consider inherited assets and existing debt separately.”

Recipient spending confirms the gap: 68% reinvest the assets, while only 11% direct any portion toward outstanding debt. The low rate of debt paydown persists even though a majority of recipients have liabilities that exceed the transfer’s value, the research found.

About 50% of all recipients reported greater peace of mind after the transfer, though the effect varied sharply with age. Heirs under 55 were 10 percentage points more likely to report that emotional boost than older recipients, the largest age-based gap in the study.

How long recipients wait for an inheritance shapes the psychological impact as strongly as the dollar amount, the researchers concluded.

Vanguard found IRA recipients carried $35,000 more in debt than they inherited, with just 11% using assets to repay liabilities.

Fewer Americans expect a transfer as credit card balances climb

The share of American adults expecting an inheritance fell from 25% to 20% in a single year, Northwestern Mutual’s 2025 Planning and Progress Study found.

Gen Z expectations dropped from 38% to 30%, and millennials fell from 32% to 26%, the steepest declines of any age group in the survey.

Among millennials who still expect an inheritance, 69% described it as critical or highly critical to long-term financial security, Northwestern Mutual reported.

The share of adults planning to leave an inheritance rose from 26% to 31% during the same twelve-month period. The gap between givers’ rising intentions and receivers’ falling expectations widened by 10 percentage points in that single year, the survey revealed.

Credit card debt reached $1.26 trillion in the second quarter of 2026, nearing the record, the Federal Reserve Bank of New York reported.

Delinquencies on credit cards and auto loans remain elevated, and warrant continued monitoring, Joelle Scally, an economic policy advisor at the New York Fed, said.

Roughly 7% of credit card balances transitioned into delinquency over the past year, a flow rate that has held steady for roughly two years, according to New York Fed data.

What the timing gap means for household balance sheets

Goncharova noted that the returns from an inheritance depend on the recipient’s existing liabilities and on how the transferred assets are ultimately deployed.

Recipients who sought professional guidance reported the largest gains in peace of mind, outstripping every other variable the researchers tested, the Vanguard paper indicated.

Revolving debt at rates above 20% compounds whether or not an inheritance arrives, and the two-decade wait multiplies that cost, the research showed.

Vanguard’s paper notes that whether heirs address high-interest liabilities in the years before a transfer, or wait until the assets arrive, shapes how much of that compounding cost becomes permanent.
