📈 Social Security COLA 2027: The 3.6% Raise Everyone Missed
by L. Mendoza
The latest Social Security COLA projection for 2027 is 3.6% (The Senior Citizens League, updated after the July 2026 inflation report released August 12). AARP projects 3.5% and CNBC puts the range at 3.4%–3.6%. At 3.6%, the average retired worker benefit of ~$1,937.53 would rise about $69.75 a month to ~$2,007.28 before deductions. The official figure is announced October 14, 2026 and higher payments start January 2027.
Here's what nobody is telling you about the Social Security COLA 2027: the projected raise is the biggest in four years — yet most retirees will still end up with less money in their pocket than the headline number suggests. The gap between the "raise" you hear about and the deposit you actually see is Medicare Part B.
The 2027 cost-of-living adjustment is calculated from the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) across July, August and September 2026. The first official data point — July's CPI-W, released August 12, 2026 — pulled forecasts down slightly from June's 3.8% to around 3.6%. That still tops the 2.8% COLA applied in 2026.
Here are the verified projections, what they mean for your monthly check, and the exact dates that matter.

What Is the Social Security COLA and Why Does 2027 Matter?
The COLA is an annual, automatic cost-of-living adjustment applied to Social Security and Supplemental Security Income (SSI) benefits. It is not voted on by Congress — it is derived from inflation data published by the Bureau of Labor Statistics. A 2027 raise of 3.6% would be the largest since 2023, after the 2.8% applied in 2026 failed to fully offset price pressure many households felt.
How Is the 2027 COLA Calculated?
The Social Security Administration compares the average CPI-W for July, August and September 2026 with the same quarter of the previous year, then rounds to the nearest 0.1%. Only the third-quarter readings count. Months like June influence forecasts but are excluded from the official calculation — which is why July's release on August 12, 2026 marked the first real data point.
Social Security COLA 2027 Key Dates
| Date | What Happens |
|---|---|
| Aug 12, 2026 | BLS releases July CPI-W — first official data point |
| September 2026 | BLS releases August CPI-W |
| October 14, 2026 | SSA announces the official 2027 COLA |
| December 2026 | SSA sends notices with your 2027 benefit |
| January 2027 | Higher payments begin for most beneficiaries |
Who Gets the 2027 COLA?
More than 75 million Americans are tied to the annual COLA: retired workers, disabled workers receiving SSDI, survivors, spouses and dependents, and SSI recipients. Everyone in those programs sees the same percentage applied to their base benefit, though the dollar amount varies by individual payment.
Will Medicare Part B Eat Your Raise?
Most retirees have their Medicare Part B premium deducted directly from their Social Security check. The 2027 standard Part B premium has not been announced, and if it rises, it absorbs part of the gross COLA. A beneficiary at $2,000 a month would gain $72 gross under 3.6% — but the deposit increase would be smaller if the Part B deduction also rises.
Could the 2027 COLA Still Change?
Yes. Two readings remain (August and September). The estimate would climb if gasoline rebounds, food or shelter accelerates, or CPI-W rises during the third quarter. It would fall if energy declines continue and inflation moderates — exactly how TSCL's projection slipped from 3.8% in June to 3.6% in July. Track the official CPI-W releases before October 14, 2026.
