Social Security COLA 2027 Estimate Holds at 3.1% After July 2026 CPI-W Report

The Social Security COLA estimate for 2027 held at 3.1% after July’s CPI-W data release. The Bureau of Labor Statistics confirmed CPI-W rose 3.4% over the 12 months ending July 2026. That trend-based calculation, from MyFederalRetirement, stayed unchanged from last month’s projection. Other forecasters see the increase running higher, ranging between 3.4% and 3.6%. The official 2027 Social Security COLA won’t be confirmed until mid-October 2026.

How the 3.1% Social Security Estimate Is Calculated

This 3.1% Social Security COLA trend estimate comes from a straightforward year-over-year CPI-W comparison. The formula divides July’s CPI-W index value by last July’s figure, then converts it to a percentage.

• July 2026 CPI-W stood at 327.104, up from 317.265 in July 2025.
• That works out to a 3.10% increase, rounded to 3.1%.

This trend-based figure differs from advocacy group forecasts, which factor in projected August and September inflation too. The Social Security Administration officially uses average CPI-W across all three third-quarter months, not just July’s reading alone.

Competing Forecasts Show a Range of Outcomes

Independent Social Security analysts currently disagree on where the 2027 COLA will ultimately land. The Senior Citizens League projects 3.6%, down from 3.8% in both May and June.

• Policy analyst Mary Johnson now estimates 3.4%, down sharply from May’s 4.7% forecast.
• AARP’s separate analysis points to a 3.5% increase for 2027 benefits.

All three estimates still exceed 2026’s actual 2.8% Social Security COLA by a meaningful margin. Inflation volatility throughout 2026, swinging from 2.2% in January to 4.4% in May, has made forecasting unusually difficult this year.

What a Higher COLA Would Mean for Benefits

A Social Security COLA in the 3.1% to 3.6% range would meaningfully boost monthly retiree payments next year. Using TSCL’s 3.6% estimate, the average benefit would rise $69.75 monthly.

• That would push average benefits from $1,937.53 to $2,007.28.
• Using the current 3.4% CPI-W figure, average benefits could reach $2,155.27.

Rising Medicare Part B premiums, projected to climb from $202.90 to roughly $218.60 in 2027, will offset some of that gain. Insurers like UnitedHealth Group, CVS Health, and Humana, which administer Medicare Advantage plans, remain closely tied to these premium adjustments.

Federal Retiree COLAs Follow a Different Formula

FERS retirees won’t receive the same Social Security COLA percentage as other beneficiaries under current law. Federal law caps FERS increases whenever the Social Security COLA exceeds 3%.

• A 3.6% COLA would translate to a 2.6% FERS COLA.
• The 3.1% trend estimate would produce a 2.1% FERS adjustment instead.

CSRS retirees, by contrast, receive the full Security COLA percentage without any reduction applied. This distinction matters significantly for the millions of federal employees covered under FERS retirement plans.

What Comes Next for the Official Announcement

The Bureau of Labor Statistics will release August 2026 CPI data on September 11, 2026. September’s CPI-W figure follows in October, completing the three-month average used for the final calculation. The Social Security Administration is expected to announce the official 2027 COLA around October 14, 2026. Until then, all current figures, including the 3.1% trend estimate, remain projections rather than confirmed numbers.

Final Thoughts

The 3.1% Social Security COLA trend estimate reflects a pure mathematical reading of July’s inflation data, not a final forecast. With other analysts projecting increases up to 3.6%, retirees should expect the real number to shift as August and September data arrive. Either way, 2027’s COLA will likely exceed 2026’s 2.8% increase for over 75 million beneficiaries nationwide.
