How Much Do American Retirees Rely on Social Security?
Social Security is the foundation of retirement income for most older Americans, but how much people depend on it varies widely. Here's what SSA and Census data show, what Social Security can and can't cover, and a planner to see how much of your own income it provides.
Quick Answer: How Important Is Social Security to Retirees?
Very — but “receiving” and “depending on” are different things. The large majority of people 65 or older get a benefit, and Social Security is the largest anti-poverty program for older Americans. A smaller share — roughly 2 in 5 older people in beneficiary families — get half or more of their income from it, according to SSA research using tax records.
How Many Retirees Rely on Social Security for Half or More of Their Income?
People aged 65 or older in families where at least one member gets Social Security; share of total family income from Social Security; income year 2015.
| Share of income from Social Security | Survey only (public CPS) | Survey + SSA + IRS records | Men* | Women* |
|---|---|---|---|---|
| 50% or more | 52.5% | 39.9% | 37.3% | 42.0% |
| 75% or more | 33.6% | 21.2% | 18.6% | 23.3% |
| 90% or more | 25.6% | 13.8% | 12.1% | 15.1% |
*Men and women columns use survey data linked to SSA and IRS records.
Why two sets of numbers? Surveys miss a lot of 401(k) and IRA withdrawals, so they make Social Security look like a bigger share of income than it is. When SSA researchers linked survey answers to tax records, the share relying on Social Security for 90% or more of income fell from about 26% to 14%. Source: SSA Working Paper 116, Table 5.
Can You Live on Social Security Alone?
There is no universal yes or no. Whether a benefit covers your needs depends on:
Housing
Owning a paid-off home versus paying rent is often the biggest difference between a benefit that covers basics and one that doesn't.
Healthcare
Medicare premiums, deductibles, prescriptions, dental, and long-term care come out of the same budget. The Census Bureau found medical expenses raised the 2025 poverty rate for people 65+ by 3.8 percentage points.
Location
Costs and state taxes vary widely; some states tax Social Security benefits and most do not.
Household size
A married couple may receive two benefits (or a worker plus spousal benefit) but also has two people's expenses.
Benefit amount
The average retired-worker benefit is about $2,170 a month after the 2027 COLA, but individual benefits range far above and below that.
Social Security vs. Other Retirement Income
| Source | How it works | Strengths | Watch out for |
|---|---|---|---|
| Social Security | Monthly benefit for life, adjusted each year for inflation (COLA) | Inflation-protected; continues for life; survivor benefits | Based on your earnings record; reduced if claimed before full retirement age |
| Traditional pension | Monthly payment from a former employer, often for life | Predictable; may include survivor option | Most private pensions have no automatic cost-of-living increase |
| 401(k) / IRA withdrawals | You decide how much to withdraw from savings | Flexible; can be large in early years | Can run out; required minimum distributions; taxable withdrawals |
| Savings & investment income | Interest, dividends, and asset sales | Accessible; can cover one-time costs | Varies with interest rates and markets |
| Part-time work | Wages or self-employment income | Can delay drawing down savings | Earnings test may withhold benefits before full retirement age |

How Inflation Affects Retirees Who Rely Heavily on Benefits
The annual COLA protects the Social Security part of your income from inflation as measured by the CPI-W. If Social Security is most of your income, that protection covers most of your budget — but if your own costs, like rent or medical bills, rise faster than the COLA, the gap comes straight out of your budget. Pensions without cost-of-living increases and fixed withdrawals lose buying power every year.
