What US Recipients Could Learn From Wednesday's Social Security 2027 COLA Announcement

Millions of Americans will learn on 14 October 2026 how much their Social Security benefits are expected to rise next year, although higher Medicare costs could offset part of the increase.

Per AL.com, the US Bureau of Labor Statistics (BLS) is scheduled to release September inflation data at 08:30 Eastern Time on 14 October 2026. Thereafter, the Social Security Administration (SSA) is expected to announce the 2027 cost-of-living adjustment (COLA).

The Senior Citizens League (TSCL) forecasts a 3.5% increase, above the 2.8% adjustment for 2026, but the official figure has yet to be confirmed.

The group estimates that a 3.5% adjustment would add $67.90 (approximately £51.32) to the average monthly Social Security benefit. On its figures, an average payment of $1,940.08 (£1,466.31) would rise to $2,007.98 (£1,517.63).

For someone receiving $2,000 (£1,511.60) a month, a 3.5% increase would mean an additional $70 (£52.91), bringing the monthly payment to $2,070 (£1,564.51).

These are illustrative calculations based on the TSCL's forecast, not confirmed 2027 payment amounts. Individual increases would depend on existing benefits.

How the Increase is Calculated

The annual COLA is intended to help Social Security and Supplemental Security Income (SSI) payments keep pace with inflation. The SSA calculates the adjustment using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).

Specifically, it compares the average CPI-W for July, August and September with the average for the same three months in the previous year. The percentage increase in that quarterly average determines the COLA, rather than the inflation rate for any single month. If the index does not increase, there is no COLA under the standard formula.

Some SSI recipients will receive two payments in October, but neither is an extra benefit. The regular October payment is followed by the November payment on 30 October because 1 November falls on a Sunday. This is a calendar adjustment, not a bonus, and it is separate from the 2027 Social Security COLA, The Hill noted.

Why a Higher Benefit May Feel Smaller

For beneficiaries who have their Medicare Part B premiums deducted directly from Social Security payments, an increase in premiums can reduce the amount of their COLA that they actually receive.

A Medicare report projects a standard monthly Part B premium of $209.50 (£158.34) for 2027, up $6.60 (£4.99) from $202.90 (£153.35) in 2026. The trustees also project an annual Part B deductible of $292 (£220.69), compared with $283 (£213.89) in 2026. These 2027 Part B figures are projections, not final premiums or deductibles.

Prescription drug coverage under Medicare Part D could bring additional costs. The standard deductible is set to rise from $615 (£464.82) in 2026 to $700 (£529.06) in 2027. The annual out-of-pocket limit is also set to increase from $2,100 (£1,587.18) to $2,400 (£1,813.92).

These figures describe the standard Part D benefit structure; actual costs will depend on a beneficiary's plan, covered medicines and prescriptions. The deductible and out-of-pocket limit are separate from the monthly Part B premium.

Even if the COLA reaches 3.5%, beneficiaries may therefore see a smaller improvement in their disposable income once healthcare expenses and other rising living costs are taken into account.

When the Higher Payments Arrive

Most Social Security recipients will receive their first payment reflecting the 2027 COLA in January 2027. SSI recipients will receive their adjusted January payment on 31 December 2026 because 1 January is a federal holiday.

Social Security payments normally scheduled for the third day of the month will also arrive on 31 December in this instance. The usual payment date, 3 January 2027, falls on a Sunday, and the preceding days include the New Year's Day holiday and a Saturday.

Meanwhile, in the TSCL's 2026 survey, 89% of respondents said the 2026 COLA was too low, while 44% reported relying entirely on Social Security for income.

TSCL executive director Shannon Benton has argued that the CPI-W does not adequately reflect older Americans' spending patterns. The concern is that a measure based on urban wage earners and clerical workers may not capture the particular pressures older people face from healthcare and other essential expenses.

The official 2027 adjustment will become clear after the September inflation data are released. Until then, the 3.5% figure remains a forecast, and the effect on each recipient's finances will depend on their benefit amount and any changes in healthcare costs.
