A single figure has been moving through retirement newsletters and social feeds since the middle of July: a 3.8 percent Social Security raise for 2027, worth roughly $74 a month. The figure is real, the arithmetic behind it is ordinary, and the organization that produced it describes it accurately. What gets stripped out in the retelling is the part that matters to anyone building a 2027 budget.
The official 2027 cost-of-living adjustment does not exist. It cannot be calculated yet, because the inflation readings that determine it have not been collected, let alone published. Roughly three months separate the estimate now in circulation from the announcement that will settle it.
What The Senior Citizens League published, and what it is not
The Senior Citizens League is a nonpartisan seniors’ advocacy organization established in 1992. In a release dated July 14, 2026, it said its projection for the 2027 COLA holds at 3.8 percent, unchanged from the previous month and a full percentage point above the 2.8 percent adjustment currently in effect.
The group’s own sentence is careful, and the care is worth preserving. “If TSCL’s projected 2027 COLA took effect today, average benefits would rise by $73.62, from $1,937.53 to $2,011.15.” The conditional at the front of that sentence is doing real work. TSCL has no role in setting the adjustment and no access to data the public does not have. It runs the same statutory formula the government will run, on a partial set of inputs, and republishes the result each month as more inputs arrive. That is a forecast, and by its own description it is subject to revision: the July release notes the figure held steady from the previous month, which is only worth saying about a number that can change.

The three months that decide the 2027 raise have not been measured
The formula is set by statute, and the Social Security Administration publishes the computation openly. A COLA equals the percentage increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W, from the average for the third quarter of the last year in which a COLA became effective to the average for the third quarter of the current year, rounded to the nearest tenth of a percentage point.
Because an adjustment took effect for 2026, the base for the 2027 calculation is the third quarter of 2025. SSA’s own table puts that average at 317.265, built from monthly CPI-W readings of 316.349 in July, 317.306 in August and 318.139 in September. The 2027 adjustment will measure July, August and September of 2026 against that base.
The Bureau of Labor Statistics calculates the CPI-W once a month, after the month closes. As of the last days of July 2026, not one of those three readings has been published. Every projection circulating today, TSCL’s included, is an estimate of what three unpublished numbers will say.
Where $73.62 comes from, and why it is unlikely to be your $73.62
A percentage applied to an average produces an average. The $73.62 is 3.8 percent of $1,937.53, and that starting figure is not a universal one. SSA’s 2026 fact sheet estimates the average monthly benefit for all retired workers at $2,071 in January 2026, after the 2.8 percent increase was applied. Two different averages, drawn from two different populations, and neither one is a particular household’s check.
The practical version is simpler. Whatever adjustment is announced applies as a percentage to a household’s own benefit. If the number lands at 3.8 percent, a $1,400 monthly benefit gains about $53 and a $2,600 benefit gains about $99. Anyone who wants a useful estimate should apply the percentage to the amount on their own award letter rather than to a national average.
There is a second reason the headline dollar figure overstates what shows up in the bank. For most beneficiaries, the Medicare Part B premium is deducted directly from the monthly payment, and that premium is set separately, later in the fall, by a different agency. The COLA alone does not determine the net change in a deposit.
October is when the estimate becomes a decision
The timing is predictable because it follows the data. The September CPI-W is the last input, so the announcement follows shortly after it is published. SSA announced the 2.8 percent adjustment for 2026 on October 24, 2025, and the same page explains what happens after: COLA notices become available in the Message Center of a my Social Security account in late November, and the new benefit amount, with the Medicare deduction already applied, is available in December.
The money itself moves later still. Since 1982, adjustments have taken effect with benefits payable for December, which beneficiaries receive in January. Supplemental Security Income payments run slightly ahead, because the normal SSI payment date is the first of the month and January 1 is a holiday.
What that leaves is a straightforward test for any 2027 figure encountered between now and the fall. SSA’s published computation for the current year is fully documented and reads (317.265 − 308.729) ÷ 308.729 × 100 = 2.8 percent. The equivalent line for 2027 has two of its three terms missing, and it cannot be written until the September 2026 CPI-W is published.
