Social Security 2027 cost‑of‑living adjustment forecasts vary between 3.7% and 4.7%, affecting average monthly checks and Medicare Part B premiums. See the

2 % COLA estimate for 2027 could swing widely, with independent analyst Mary Johnson now projecting 3.7% after a June inflation dip, down from a 4.7% forecast made a month earlier [1]. The range matters because a higher COLA would lift average benefits but also signals lingering inflation that could erode purchasing power.

| At a glance | |
|---|---|
| Prior 2026 COLA | 2.8% |
| Current 2027 COLA forecasts | 3.7% (downgraded) to 4.7% (peak) |
| Average 2026 benefit | $2,071 per month |
| Projected 2027 benefit increase | $81‑$97 per month depending on COLA |
| 2026 Medicare Part B premium | $202.90 (up from $185) |

## Forecasts diverge as inflation data evolves  
The Social Security cost‑of‑living adjustment is tied to the CPI‑W for the third quarter. After May’s CPI‑W rose 4.4% year‑over‑year, Johnson lifted her 2027 COLA estimate to 4.7% [2]. A month earlier she had pegged it at 4.2%, and the Senior Citizens League now sees a 3.8% increase [2]. However, a cooler June inflation report prompted Johnson to cut her projection to 3.7% [1], illustrating how quickly the outlook can shift with new data. The official COLA will be announced in mid‑October once September CPI‑W figures are available.

## Impact on retirees’ take‑home pay  
If the 4.7% COLA materializes, the average monthly Social Security check could rise from $2,071 to roughly $2,168, adding about $97 per month [3]. Even the lower 3.7% scenario would still boost the average check by roughly $77. Yet retirees must consider Medicare Part B premiums, which rose to $202.90 in 2026 from $185 [2]. Any similar increase in 2027 would offset much of the COLA gain, especially for those whose benefits are largely consumed by healthcare costs.

## What to watch  
- September CPI‑W release (the basis for the official COLA) – scheduled for early October.  
- Medicare Part B premium adjustments for 2027, typically announced in the fall.  
- Any further inflation data in the third quarter that could push the COLA above or below the current forecast range.

The final COLA will determine whether retirees see a meaningful boost in real income or simply a nominal increase that keeps pace with still‑elevated prices. The coming weeks of inflation data will be decisive.
