Quick Read
Average retiree households spend $61,432 a year, but Social Security pays only about $24,850 annually, leaving a gap of roughly $37,000.
81% of retirees supplement Social Security with private income, including pensions (56%), investment income (48%), or 401(k)/IRA withdrawals (33%).
Medicare Part B withholds $203 a month from Social Security checks before deposit, shrinking the net benefit retirees actually receive.

The U.S. Bureau of Labor Statistics puts average annual spending for households headed by someone 65 to 74 at $65,354 in 2024, based on the latest Consumer Expenditure Survey data. That is lower than the $78,535 average across all households, but it remains a significant annual bill for housing, food, transportation, insurance, and healthcare. The central question for retirees is simply what covers those costs.

Social Security is the anchor of retirement income for most households. The average retired-worker benefit reached roughly $2,084 a month by mid-2026, or about $25,000 a year. When you divide that into the $65,354 annual spending figure, Social Security covers roughly 38% of what the typical retiree household actually spends. “About a third” is now a more accurate description, confirming that the majority of income must come from elsewhere.
Where the Rest of the Money Comes From
The Federal Reserve’s most recent survey of household economic well-being found that 81% of retirees reported at least one private source of retirement income in addition to Social Security. The three largest categories were traditional pensions, investment income, and withdrawals from retirement accounts. Specifically, 56% of retirees had pension income, 48% reported interest, dividends, or rental income, and 33% were drawing down a 401(k) or IRA. A meaningful minority also had part-time earnings.

Story Continues
Those private sources show up in the national accounts. The Bureau of Economic Analysis reports that in the first quarter of 2026, Americans received $4,281.5 billion in income from assets and $1,630.3 billion in Social Security benefits. Asset income across the economy is now roughly two and a half times Social Security payments, a proxy for how much of retirement is funded outside the program.
Medicare Takes a Bite Before the Money Arrives
The gross Social Security number overstates what actually lands in a retiree’s checking account. The standard Medicare Part B premium is $202.90 a month in 2026, and it is typically withheld from the Social Security check before it is deposited. The Part B annual deductible is $283, and a single hospital stay carries a Part A inpatient deductible of $1,736. Retirees often owe additional premiums for Part D and supplemental plans, which is why the share of spending that Social Security covers continues to shrink in practice.
What Investment Income Actually Yields Right Now
For retirees leaning on savings to close the gap, the current rate environment matters. The 10-year Treasury yield sat at 4.55% as of July 7, 2026, while the FDIC national average yield on a 12-month CD was 1.65%. The gap between those two numbers matters because the CD figure is the bank’s average, and top online banks routinely pay several times that rate. The difference between earning the national average and a Treasury-level yield on a typical cash balance can amount to roughly a month of average retiree spending over the course of a year.
Inflation is the reason the arithmetic keeps tightening. The Consumer Price Index for Urban Wage Earners, which the SSA uses to set the COLA, reached 328.8 in May 2026, up from 316.3 in July 2025. Personal consumption on healthcare services alone rose from $3,512.1 billion in May 2025 to $3,716.0 billion in May 2026, a category that retirees consume disproportionately. Retirees whose income is weighted toward Social Security receive a COLA that trails their actual spending basket, and the share of expenses covered by the check drifts down over time.
The Rest of the Math
The numbers point to three sources that fill the gap between what Social Security pays and what retirees spend: a pension for those who still have one, systematic withdrawals from a 401(k) or IRA, and interest and dividends from taxable savings. Housing equity supports some retirees through downsizing or a paid-off home that eliminates the largest line item. Part-time work covers the rest for a smaller group. For most households, Social Security serves as the floor, and the private half of the equation, pensions, withdrawals, and asset income, determines whether the $61,432 in annual spending feels manageable or tight.
