A $55-per-month raise sounds better than nothing, until you measure it against what rent, prescriptions, and groceries actually cost. For the second consecutive year, Social Security beneficiaries are on track for a cost-of-living adjustment of just 2.8%, based on intermediate assumptions published in the 2025 Social Security Trustees Report. That would mirror the 2.8% increase already in effect for 2026 and represent a steep drop from the 8.7% adjustment beneficiaries received in 2023, the largest in more than 40 years.
Roughly 72.5 million Americans collect Social Security or Supplemental Security Income each month, according to SSA’s latest statistical snapshot. The average retired worker’s benefit as of January 2026 is about $1,976. A 2.8% bump would add approximately $55 to that monthly check. Whether that keeps pace with what households actually spend is a different matter.
Where the 2.8% projection comes from
Social Security’s annual COLA is not set by Congress or the White House. It is driven by a formula tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), the only inflation measure Congress has authorized for this purpose. Each fall, the Social Security Administration compares the average CPI-W reading from the third quarter of the current year to the same quarter of the prior year. The percentage change becomes the following January’s adjustment.
The 2026 COLA of 2.8% was locked in using CPI-W data from July through September 2025. The 2027 projection of another 2.8% comes from the Trustees Report’s intermediate economic scenario, which models future inflation, wage growth, and demographic trends. That intermediate path is the baseline most analysts and federal budget planners reference. It assumes inflation stays contained but does not fall low enough to produce a near-zero adjustment.
Advocacy groups have long argued that CPI-W understates the inflation retirees actually face. The index tracks spending patterns of working-age hourly and clerical employees, not older adults who typically devote larger shares of their income to health care and housing. An alternative gauge, the CPI-E (Consumer Price Index for the Elderly), has been proposed as a replacement, but Congress has never adopted it.
Why the final number could still shift
A projection is not a locked-in figure. The actual 2027 COLA will not be determined until the Bureau of Labor Statistics publishes CPI-W data for July, August, and September 2026. As of May 2026, those readings do not yet exist, and the SSA’s historical CPI-W table will only be updated as each month’s numbers are released.
Several forces could push the final figure higher or lower. Tariff activity and lingering supply-chain disruptions have introduced pricing pressures that the Trustees’ assumptions, finalized earlier in the year, may not fully capture. Energy prices remain volatile. And Federal Reserve interest-rate decisions over the summer will shape borrowing costs, consumer spending, and ultimately the inflation data that feeds the COLA formula.
If a supply shock or energy spike drives CPI-W above expectations, the 2027 COLA could land above 2.8%. A pronounced economic slowdown, on the other hand, could pull inflation down and produce a smaller increase. Both outcomes remain plausible, which is why the fall announcement from SSA, typically in mid-October, is the only definitive word.
The Medicare bite most people overlook
Even when beneficiaries receive a COLA, a chunk of it is often swallowed by rising Medicare Part B premiums, which are deducted directly from Social Security checks for most enrollees. The standard Part B premium for 2026 is $185 per month, up from $174.70 in 2025. If premiums climb again for 2027, some retirees could watch much of their roughly $55 monthly raise vanish before it hits their bank accounts.
This dynamic explains why many beneficiaries feel their checks shrink year after year, even when the COLA is positive. The adjustment is calculated on gross benefits, but what matters to households is the net deposit after Medicare and other withholdings are subtracted.
A modest raise at a moment of growing dependence
The 2.8% figure arrives as more Americans than ever rely on Social Security as a primary income source. The population aged 65 and older grew from 40.3 million in 2010 to 55.8 million in 2020, a 38.6% jump, and that wave has only accelerated as baby boomers continue crossing into retirement.
Recent COLAs tell the story of a post-pandemic whipsaw:
- 2023: 8.7%, the largest adjustment since 1981
- 2024: 3.2%
- 2025: 2.5%
- 2026: 2.8%
- 2027 (projected): 2.8%
After the 2023 spike, itself a delayed response to the post-pandemic inflation surge, adjustments have settled into a range that many retirees say does not reflect what they actually pay at the pharmacy, the gas pump, or the supermarket.
Hanging over all of this is the trust fund’s financial outlook. The 2025 Trustees Report projects that the combined Old-Age and Survivors Insurance and Disability Insurance trust funds will be depleted around 2033 to 2035 under intermediate assumptions. At that point, incoming payroll tax revenue would cover only about 79 to 83 cents of every dollar in scheduled benefits. That timeline adds urgency to every COLA conversation, because even a modest annual raise compounds the system’s long-term obligations.
Several legislative proposals aim to address the gap. The Social Security 2100 Act, most recently reintroduced in the 118th Congress, would switch the COLA formula from CPI-W to CPI-E and boost minimum benefits. None of these bills have reached a floor vote, but they remain part of the policy debate as the depletion date draws nearer.
What retirees can actually plan around
Until the third-quarter CPI-W data arrives this fall, 2.8% is the most grounded planning number available. For millions of retirees already stretching fixed incomes to cover bills that keep climbing, the raise is not the issue. The issue is whether a formula designed decades ago still measures the right things for the people who depend on it most.
