Retirees Spend the Most From 65 to 74 and the Least From 75 to 84. Most Plans Assume the Opposite and Underspend the Years That Matter.
Most retirement plans treat spending as a flat line adjusted for inflation, but actual retiree behavior follows a completely different shape, and the mismatch costs people during the years they are most capable of enjoying the money.

If you are building a retirement plan around a flat spending number adjusted only for inflation, you have a problem worth addressing. The Bureau of Labor Statistics Consumer Expenditure Survey breaks things out by the age of the householder, and the pattern is consistent year after year. Total average annual spending for households headed by someone in the 65 to 74 range is meaningfully higher than for those headed by someone in the 75 to 84 range. Across all U.S. households, average annual expenditures hit $78,535 in 2024, up from $77,280 the year before. But retiree cohorts sit well below that top line, and they diverge from each other in ways that flat-spending models never account for.
Fixing the Headline Before Fixing the Plan
Most retirement plans assume constant inflation-adjusted spending, meaning the same purchasing power every year after inflation. That assumption fails against observed behavior, because the CES tables and academic work on the retirement spending curve show consumption falling through the middle retirement years.
Spending does not fall forever. Published research describes a curve that declines through the 70s and then bends back up in the oldest cohort as health and long-term care costs arrive. A plan that only extrapolates the decline underfunds the years when medical bills tend to peak. Long-term care is the specific expense that pulls the tail of the curve upward.
What Actually Changes Between 65 and 84
The real story is how spending categories shift. The Consumer Expenditure tables show that transportation, entertainment, dining out, and apparel all drop as retirees move from the 65 to 74 bracket into the 75 to 84 bracket. Healthcare moves in the opposite direction, climbing as a share of the budget in the 75 to 84 group and again for households 85 and older, driven by out-of-pocket costs, supplemental insurance premiums, and eventually paid care.
That compositional shift is exactly what a flat real-spending assumption hides. A budget line that treats everything as one number cannot tell you that your travel budget has a shelf life while your medical budget does not. National consumption data reinforces which categories matter most. In July 2026, U.S. personal consumption on healthcare services ran at $3,830.8 billion at an annual rate, right behind housing at $3,979.8 billion and well above recreation at $877.9 billion. Retirees follow the same broad categories, just weighted differently as they age.
Practical Case Against Flat Spending Plans
A retiree who spreads a portfolio evenly across a 30-year horizon, in real terms, is by construction underspending the years when health and mobility make the money most useful. The 4% rule is conservative on purpose, and conservatism is a feature when longevity is uncertain. Conservatism becomes a waste when it leaves large reserves in an 85-year-old’s account that could have paid for experiences at 68 (we made the full case against flat withdrawal math and the income-first alternative in a free report).
Longevity risk, the risk of living longer than the plan assumes, is the strongest argument for a flat or rising spending assumption. Long-term care costs are the second, and they are lumpy and unpredictable. The declining pattern in the CES tables is an average across many households, not a promise about any one household. A retiree who front-loads spending and then needs three years of memory care has a genuine problem, and no chart should talk anyone out of a safety margin.
Some of the decline is a constraint rather than a preference. Households with less money spend less at every age, and low-income retirees in the 75 to 84 bracket may be spending less because they have less, not because they want less.
What the Data Tells Retirees to Do
Think of retirement spending as a curve rather than a straight line. Budget for higher discretionary spending in the first decade, expect the middle years to ease off on travel and transportation, and set aside capacity for healthcare and potential long-term care in the final stretch. The 2027 Social Security cost-of-living adjustment is tracking at 3.1%, which adjusts income for general inflation but does nothing to reshape how spending actually flows across the retirement arc. That reshaping is up to you, and the data suggests the shape looks a lot like a smile.
