How Age Shapes Household Spending
Consumer Expenditure data across seven age cohorts reveals a lifecycle spending pattern that defies simple assumptions about aging and money. According to the U.S. Bureau of Labor Statistics 2023 Consumer Expenditure Survey, the 35-to-44 reference-person cohort posts the highest annual outlay among 13,000+ surveyed households, while the under-25 and 75-and-over cohorts each spend roughly 40% less; see our methodology for how the BLS aggregates and inflation-adjusts each cohort.
The Arc of Total Spending
Total household expenditures follow a predictable arc: rising from the youngest age group (under 25) through peak spending years (45-54), then declining into retirement. The 45-54 cohort spends the most in absolute terms, typically 40-50% more than the under-25 group. This peak coincides with maximum earning years and the simultaneous pressure of mortgage payments, children's expenses, and career-related costs.
But total spending is less interesting than the composition shifts. What households spend on changes dramatically across age groups, and these shifts reveal fundamental differences in lifecycle priorities.
Healthcare: The Age-Driven Category
Healthcare spending shows the most dramatic age gradient of any major category. Americans 65 and older spend more than twice what those under 35 spend on healthcare, driven by Medicare supplemental premiums, prescription drugs, and medical services utilization. This gradient accelerates, the 65-74 cohort spends substantially more than the 55-64 cohort, and the 75+ group spends even more.

Housing: From Rent to Mortgage to Freedom
Housing spending follows a different pattern than total spending. The youngest households (under 25) spend heavily on rent as a share of income. The 35-54 cohorts carry the highest absolute housing costs, mortgages on larger homes, property taxes, maintenance. After 65, housing costs often drop significantly as mortgages are paid off, though property taxes and maintenance persist.
The housing tenure dimension on PlainHousehold shows this clearly: owners without mortgages (predominantly older households) have dramatically lower total housing expenditures than owners with mortgages, even in the same age bracket.
What This Means for Financial Planning
The lifecycle spending pattern has practical implications for budgeting and retirement planning. The common assumption that spending drops significantly in retirement is partially true (lower transportation, less apparel, lower food away from home) but healthcare increases and housing persistence often mean the decline is less dramatic than expected.
