Every autumn, the federal government announces how much Social Security checks will rise the following year, and tens of millions of retirees plan their budgets around the number. For 2027, one of the most closely followed independent estimates has just moved sharply in the wrong direction for beneficiaries, falling a full percentage point in the span of a single month. The figure is only a projection, not the official adjustment, but the drop signals that next year’s raise may land well below what earlier forecasts suggested.
A forecast that fell a full point in a month
The annual increase, known as the cost-of-living adjustment, or COLA, is meant to keep benefits from losing value as prices rise. It is not decided by a vote or a political negotiation. Instead, it is calculated from a specific measure of inflation, which means a cooling economy translates directly into a smaller raise. That is exactly what appears to be unfolding as 2026 progresses.
Independent Social Security analyst Mary Johnson lowered her 2027 COLA estimate from 4.7 percent to 3.7 percent within a single month, according to reporting by CNBC, one of the steeper one-month declines in an estimate in several years. The Senior Citizens League, a nonpartisan advocacy group that tracks the adjustment, held its own projection near 3.8 percent, which would add roughly $74 a month to the average retiree benefit. Both numbers are estimates produced outside the government, and both could shift again before the official figure is set.
The gap between a 4.7 percent raise and a 3.7 percent raise is not trivial for a household living on Social Security. On a typical benefit, a single percentage point can amount to well over a hundred dollars across a year, money that matters most to the retirees who rely on the check for the majority of their income.

Why the estimate dropped
The revision followed a fresh inflation reading. Consumer prices in June rose about 3.5 percent from a year earlier, a slower pace than in prior months, based on the Consumer Price Index published by the Bureau of Labor Statistics. Because the COLA is tied to inflation, a cooler reading pulls the projected adjustment down with it. Forecasters update their estimates each month as new price data arrives, which is why a single report can move a projection by a full point in either direction.
It is worth stressing that a monthly estimate is a moving target, not a promise. A projection built on June data can climb again if prices reaccelerate over the summer, or fall further if inflation keeps cooling into the fall. The only figure that ultimately counts is the one calculated from the actual late-summer readings, which is why analysts caution against banking a budget on any single month’s projection, whether it points up or down.
How the official number is actually set
The estimates circulating in July are not the figure that will appear on benefit statements. The Social Security Administration sets the official COLA using the Consumer Price Index for Urban Wage Earners and Clerical Workers, comparing the third quarter of one year with the third quarter of the next, as the agency explains in its cost-of-living methodology. Only the July, August, and September readings count, so months of data still remain before the calculation is complete. The agency typically announces the final adjustment in mid-October, and it takes effect with benefits paid the following January, per its official COLA notices.
What a smaller raise means in dollars
For beneficiaries, the size of the raise determines how far a fixed income stretches against rent, groceries, and medical bills. If the adjustment lands near the current estimates, the average retiree would see roughly $74 more a month, based on the Senior Citizens League figure. Part of any increase, though, is often absorbed by the standard Medicare Part B premium, which is deducted directly from most benefit checks and tends to rise each year. A COLA that trails retirees’ real costs, particularly for health care and housing, can leave a household with less buying power even after the raise arrives.
Some perspective explains why beneficiaries watch the number so closely. Recent adjustments have swung widely, from the largest raises in four decades during the 2022 and 2023 inflation surge to far more modest increases in the years since. A 3.7 percent adjustment would sit in the middle of that recent range, larger than the leanest years but well short of the outsized pandemic-era jumps many retirees came to expect. For households that budgeted around those bigger raises, a return to more ordinary numbers can feel like a squeeze even when the check still rises.
Beneficiaries cannot change the COLA, but they can blunt the effect of a smaller one. The clearest lever is the fall Medicare open enrollment period, when comparing drug and Advantage plans can lower next year’s out-of-pocket costs and offset a lean raise. Trimming recurring expenses, shopping insurance policies, and reviewing where idle savings sit can each recover money that a modest COLA leaves on the table. Until the government publishes the official number in October, the 3.7 to 3.8 percent range remains a projection, and planning a 2027 budget around the smaller estimates, rather than the earlier 4.7 percent figure, is the more prudent bet.
There is also a longer-running debate about whether the COLA truly keeps pace with what retirees actually spend. The index the government uses tracks the buying habits of urban wage earners and clerical workers, a group that is generally younger and still working, rather than the older households that receive benefits. Seniors tend to devote a larger share of their money to health care and housing, categories that have often climbed faster than the overall index. Advocacy groups have argued for years that this mismatch leaves benefits slowly losing ground, which is one reason a lean adjustment draws such close scrutiny. Whatever the official 2027 figure turns out to be, the gap between a headline raise and a household’s real cost of living is the number retirees ultimately feel at the checkout counter and the pharmacy.
