Social Security’s 2027 cost-of-living adjustment is now being forecast at 3.7% to 3.8%, a step up that would give beneficiaries a larger monthly check if the estimate holds. That would also make the 2027 Social Security benefit increase forecast one of the bigger annual raises in recent memory.
The estimate matters now because it is being tied to inflation pressures that are still working through the United States economy. Social Security recipients already saw a 2.8% payout boost this year, but a higher 2027 COLA would matter more than a small bump because it would be set against prices that have stayed elevated in the current inflation cycle.
Mary Johnson is forecasting a 2027 COLA of 3.7%, while The Senior Citizens League puts the estimate at 3.8%. Either figure would put the increase in rare company. Over the last 36 years, the only larger or comparable raises cited were 4.1% in 2006, 5.8% in 2009, 5.9% in 2022 and 8.7% in 2023. That would make a 3.7% or 3.8% increase the fifth-largest of that span, with the ranking based on the size of the annual COLA itself, not on how many beneficiaries receive it or how large individual checks are.
The mechanism is straightforward even if the politics are not. Social Security COLAs are tied to inflation, and the latest projections are being pushed higher by the same price pressure that has fed talk of tariffs and other shocks. The article frames the forecast as being influenced by sweeping global tariffs and higher reciprocal tariffs unveiled in early April 2025, then by a new round of tariffs ranging from 10% to 12.5% on more than 80 countries announced a little over a week ago. It also links the picture to the strain after President Donald Trump approved military action against Iran on Feb. 28, followed by Iran’s shutdown of the Strait of Hormuz to most maritime traffic, which the article says precipitated the largest modern-day energy supply disruption.
That is where the forecast becomes less comforting than it first looks. A bigger COLA would help beneficiaries keep up with higher prices, but it would also add cost to Social Security and, over time, to current and future beneficiaries who depend on the program’s finances. The report also notes that inflation in the United States was back above 4% and core CPI inflation was 2.9% in the quoted update, a combination that keeps pressure on the formula that governs annual benefit changes.
For now, the 2027 increase remains a forecast, not a final figure. The official COLA will not be locked in until the inflation data are complete and the adjustment is calculated, but if the estimate holds, the increase would be large enough to lift checks meaningfully and large enough to deepen the strain that comes with paying for those checks.
