Every fall, the same question lights up search engines: "What will the Social Security COLA be next year?" If you rely on Social Security — or you're planning to — the annual cost-of-living adjustment directly affects your raise.
Here's where the 2027 COLA stands as of September 2026, how the number actually gets set, and — more importantly — how to build a plan that holds up no matter where it lands.
Updated September 15, 2026.
The Current Estimate: 3.6%
The 2027 COLA isn't official yet, but for the first time this year there's both a firm consensus number and a firm date.
Analysts currently estimate the 2027 COLA at 3.6% — which would be the largest raise since 2023, and a meaningful step up from the 2.8% that took effect in January 2026. The Senior Citizens League had projected 3.8% in July, then revised to 3.6% after July's inflation data came in softer.
It is still an estimate. Analysts are working from partial data, because the calculation isn't finished.
By law, the COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), comparing the third quarter (July–September) of one year to the same quarter the prior year. The 2027 adjustment depends on July–September 2026 inflation data — and September's figures aren't published until October. That's the last missing piece.
The official timeline:
| Milestone | Timing |
|---|---|
| Q3 2026 CPI-W data collected | July–September 2026 |
| September CPI-W released | October 2026 |
| SSA announces the 2027 COLA | October 14, 2026 |
| New benefit amount takes effect | January 2027 |
What a 3.6% COLA would mean in dollars
Applied to the SSA's 2026 figures:
| 2026 figure | Now | With a 3.6% COLA |
|---|---|---|
| Average retired-worker benefit | $2,071/month | ~$2,146/month (+$75) |
| Maximum benefit at full retirement age | $4,152/month | ~$4,302/month (+$150) |
For the average retired worker, that's roughly $895 more per year — before Medicare premiums are deducted. Hold that thought; it matters more than the headline percentage.
Editor's note: Treat 3.6% as a strong estimate, not the answer. The Social Security Administration is the only source of the official figure, and it can't be finalized until Q3 2026 inflation is fully measured. If September's inflation data surprises, the number will move.
Where the COLA Has Landed Recently
Context helps. Here are the actual adjustments from the Social Security Administration:

|---|---|
| 2022 | 5.9% |
| 2023 | 8.7% |
| 2024 | 3.2% |
| 2025 | 2.5% |
| 2026 | 2.8% |
The pattern is clear: the enormous post-pandemic adjustments (8.7% in 2023) have given way to more typical raises in the 2.5–3% range as inflation cooled. Unless inflation reaccelerates sharply in the third quarter of 2026, a COLA in that lower-single-digit neighborhood is the historically normal expectation — but the official 2027 figure won't be confirmed until October 2026.
What the 2026 COLA Looks Like (Your Current Baseline)
Before guessing about 2027, anchor on what you're actually receiving now. The 2026 COLA is 2.8%, effective January 2026. Per the SSA 2026 COLA fact sheet:
| 2026 figure | Amount |
|---|---|
| Estimated average benefit, retired worker | $2,071/month |
| Maximum benefit at full retirement age | $4,152/month |
| Maximum taxable earnings (Social Security) | $184,500 |
| Earnings limit (under full retirement age) | $24,480/year |
These are the numbers a 2027 COLA will be applied on top of. A 2.8% raise on a $2,071 benefit, for example, adds about $58/month.
The Uncomfortable Truth About COLAs
A COLA keeps benefits from losing ground to measured inflation — but it doesn't always keep up with the costs retirees actually face.
- CPI-W tracks working-age spending, which weights gasoline and electronics more heavily than the healthcare and housing costs that dominate many retirees' budgets.
- Medicare Part B premiums are often deducted directly from Social Security. In years when premiums rise faster than the COLA, a chunk of your "raise" disappears before it reaches your bank account.
In other words: treat the COLA as inflation protection, not a real raise. Planning as if it will meaningfully grow your purchasing power is a common and costly assumption.
How to Plan Smartly — Whatever the Number Is
You can't control the COLA. You can control how much your plan depends on it.
- Don't assume large COLAs in your projections. Modeling future Social Security with optimistic raises inflates your plan. A conservative inflation assumption keeps you honest.
- Stress-test a reduced benefit. According to the 2026 Social Security Trustees Report, the OASI trust fund can pay full scheduled benefits through the fourth quarter of 2032, after which ongoing payroll taxes would still cover roughly 78% of scheduled benefits — about a 22% reduction. Prudent plans model a 20%+ benefit reduction as a worst case. (More on this in when to claim Social Security.)
- Optimize your claiming age. Delaying benefits increases them roughly 8% for each year past full retirement age up to 70 — and the COLA compounds on a larger base. This is one of the few levers fully within your control. See the best age to claim.
- Build COLA assumptions into a real model. RetirePro lets you set your own inflation and Social Security assumptions, then runs 1,000 Monte Carlo scenarios to show whether your plan survives a future of smaller raises or reduced benefits — not just a single rosy projection.
Frequently Asked Questions
When will the 2027 Social Security COLA be announced? October 14, 2026, when the Social Security Administration is expected to announce the figure following the release of September CPI-W data. The new amount takes effect with January 2027 payments.
Will the 2027 COLA be higher or lower than 2026's 2.8%? Higher, if current estimates hold. Analysts project roughly 3.6% for 2027 versus the 2.8% that took effect in January 2026 — which would make it the largest adjustment since 2023. The official number arrives October 14.
How much more will I actually receive each month? It depends on your benefit. At an estimated 3.6%, the average retired-worker benefit of $2,071/month would rise by roughly $75/month (about $895/year). Remember that Medicare Part B premiums are typically deducted directly from your payment, so a premium increase can absorb part of the raise.
Does the COLA keep up with retirees' real costs? Not always. The COLA is tied to CPI-W, which reflects working-age spending patterns. Rising Medicare premiums and healthcare costs can erode the effective increase, which is why many retirees find their raise doesn't stretch as far as the headline percentage suggests.
Will Social Security still be there for me? The program is not "going bankrupt." Even under the Trustees' projection that OASI reserves run out in the fourth quarter of 2032, incoming payroll taxes would still fund roughly 78% of scheduled benefits without any reform. Planning for a possible partial reduction — not a total loss — is the realistic approach.
