Households headed by someone age 65 or older spent an average of $61,432 in 2024, according to the Bureau of Labor Statistics Consumer Expenditure Survey. That works out to roughly $5,119 a month. Social Security, meanwhile, pays the average retired worker about $2,081 per month as of spring 2026, based on the Social Security Administration’s monthly statistical snapshot. The arithmetic leaves a monthly shortfall of roughly $3,000 that must come from elsewhere.
That gap is the entire retirement math problem in one line. What follows is where the spending goes, why the gap has grown recently, and the income sources retirees are using to close it.
Where the $5,000 a Month Actually Goes
National consumption data confirm that housing and healthcare dominate retirees’ budgets. Across all U.S. households in May 2026, housing services totaled $3,950.3 billion at an annualized rate, and healthcare services totaled $3,716.0 billion, together accounting for 34.7% of total personal consumption. For retirees, whose discretionary spending is typically lower, the share sits even higher.
Food is the next line most people notice. Combined spending on food at home and food services reached an annualized $3,105.1 billion in May 2026, or about 14.1% of total consumer spending. Gasoline, at an annualized $552.8 billion, is smaller in aggregate but disproportionately visible in a fixed-income household because the price moves so much month to month.
Why the Gap Has Widened in 2026
Social Security benefits are indexed to CPI-W, and the 2026 cost-of-living adjustment came in at 2.8%. The actual inflation retirees are paying has run hotter than expected. Headline PCE inflation reached 4.1% year over year in May 2026, up from 2.9% in February. Services inflation, which captures healthcare and housing costs, sat at 3.8% year over year.
Energy is the sharper problem. The PCE energy index rose 24.3% year over year in May 2026 after being modestly negative in January. That kind of swing directly hits utility bills and driving costs, categories retirees cannot easily trim.
What Retirees Are Using to Close the Gap
For most households, the first source is accumulated savings and investment income. Nationally, income receipts on assets ran at $4,281.5 billion in the first quarter of 2026, a stable line item that includes interest, dividends, and rental income. The yields available on safe cash have compressed. The FDIC’s national average 12-month CD rate stood at 1.65% in June 2026, down from a 12-month peak of 1.76% in August 2025.
Inflation-linked government bonds have become more attractive in that environment. Series I savings bonds issued between May and October 2026 carry a composite rate of 4.26%, built from a 0.9% fixed component and a semi-annual inflation adjustment.
Home equity is the second lever, and it is a large one. The S&P CoreLogic Case-Shiller National Home Price Index reached 332.7 in April 2026, sitting in the 90th percentile of its historical range. That elevated level supports proceeds from downsizing, HELOC borrowing capacity, and reverse mortgage draws, all of which show up in retiree cash flow when Social Security and portfolio withdrawals fall short.
Claiming timing itself remains a meaningful lever. Each year of delay past full retirement age, up to 70, raises the benefit by about 8%, and claiming at 62 rather than 67 reduces the benefit by up to 30%. Because Social Security typically replaces about 40% of pre-retirement income for the average worker, the size of the gap is largely determined by claiming age and lifetime earnings, before other assets enter the picture.
The Bottom Line
The average retiree household spends roughly $5,000 a month, while Social Security provides about $2,081. The remaining $3,000 comes from a combination of savings withdrawals, investment income, home equity, pensions (where they still exist), and part-time work. Inflation running above the 2026 COLA means that the gap is growing in real terms this year, and the categories driving the pressure, housing, healthcare, and energy, are the ones retirees have the least ability to substitute away from.
