Social Security’s $75 monthly boost has a catch: Why the 2027 COLA may fall short as trust fund depletion looms

Social Security benefits will rise by 3.6% in January 2027, giving the average retired worker about $75 more per month. The increase is the largest since 2023, but retirement advocates warn that it may still leave older Americans struggling to cover everyday expenses.

The Social Security Administration announced the adjustment on October 14. For a retired worker receiving around $2,087 a month, the new payment will be approximately $2,162. That amounts to roughly $900 in additional benefits over a full year.

The problem is not simply the size of the increase. Experts at The Senior Citizens League, a nonpartisan retirement advocacy group, have raised concerns about how the government calculates the annual adjustment and when beneficiaries receive it.

Social Security also faces a separate funding challenge, with trust fund reserves projected to run out in the coming years unless lawmakers change the programme's financial outlook.

Social Security's COLA formula may not reflect retirees' actual expenses

The annual cost-of-living adjustment, known as COLA, is supposed to help Social Security benefits keep pace with inflation. Yet the formula does not measure inflation using a price index designed specifically around the spending habits of older Americans.

Instead, the Social Security Administration uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. The agency compares the average index for July, August and September with the average for the same period a year earlier. The percentage increase determines the following year's adjustment.

For 2027, the relevant year-over-year inflation readings were 3.4% in July, 3.5% in August and 3.9% in September. The resulting adjustment is 3.6%.

Housing, medical care and prescription drugs can take up a significant share of an older household's budget. If these expenses rise faster than the prices reflected in the CPI-W, a COLA based on that index may not be enough to maintain purchasing power.

The Senior Citizens League wants the government to consider the Consumer Price Index for the Elderly, or CPI-E. This alternative index gives greater weight to spending categories that can have a larger effect on older Americans.

The organisation's 2026 Loss of Buying Power study estimated that Social Security benefits had lost 13.7% of their purchasing power between 2016 and 2026. According to its calculations, benefits that once bought $1 worth of goods and services were worth about 86 cents in purchasing power a decade later. This is the group's estimate, based on its own analysis, rather than an official measure of every retiree's individual inflation rate.

Changing the formula would require congressional action. Until lawmakers approve a change, the existing CPI-W method will continue to determine annual COLAs.

Retirees must wait until January for an increase based on earlier inflation

The 2027 COLA calculated on the inflation measured during the third quarter of 2026, but most Social Security recipients will not receive their higher payments until January. By then, they will already have spent months paying prices that the adjustment is intended to help them manage.

A COLA does not reimburse beneficiaries for money they have already spent. It raises future payments to account for measured inflation, rather than paying back the difference between earlier bills and the income retirees received at the time.

Some retirees may use savings to bridge the gap. Others may have to cut spending in areas where they have more flexibility. The extent of the pressure varies by household, depending on benefit amounts, housing costs, healthcare needs and other sources of income.

The Senior Citizens League has reported similar concerns in its surveys. In a 2026 survey cited by the organisation, 89% of respondents said they believed the previous COLA was too low and that their benefits would fall behind inflation. The comparable figure in its 2025 survey was 94%, according to the group's published account.

Trust fund depletion remains a separate risk for Social Security benefits

The debate over the COLA comes as Social Security faces a long-term financial problem. The 2026 trustees' report projects that the programme's combined Old-Age and Survivors Insurance and Disability Insurance trust fund reserves will be depleted in 2034 if lawmakers make no changes. At that point, continuing income would cover about 83% of scheduled benefits under the trustees' projections.

The retirement and survivors trust fund, considered separately, faces an earlier projected depletion date in the fourth quarter of 2032. The trustees estimate that continuing income would then cover 78% of scheduled benefits from that fund.

These projections do not mean Social Security payments would automatically stop when the reserves run out. Payroll taxes and other programme income would continue. The problem is that this revenue would not be sufficient to pay all scheduled benefits under the trustees' assumptions.
