The 2027 Social Security COLA: What Should Ohio Retirees Watch For?
Quick answer: The 2027 Social Security cost-of-living adjustment (COLA) is currently estimated in the mid-3% range — recent projections put it around 3.5% to 3.6% — which would be the largest increase in a few years, up from the 2.8% COLA for 2026. These are estimates, not the final number: the official 2027 COLA is expected to be announced by the Social Security Administration in mid-October 2026, once September's inflation data is in. But here's the nuance most coverage misses: the COLA percentage isn't your real raise. For retirees on Medicare, rising Medicare Part B premiums are typically deducted directly from Social Security payments — so your net increase is the COLA minus any Medicare premium increase. Understanding this "net COLA" is key to knowing what will actually land in your monthly deposit. For Columbus, Ohio retirees, the COLA is worth watching, but it's the net figure — and how it fits your overall plan — that matters most. This article is educational; the figures cited are current estimates and are not final.

What the 2027 COLA Estimates Show
Every fall, retirees wait to learn how much their Social Security benefits will increase in the coming year through the cost-of-living adjustment, or COLA. Right now, in mid-September 2026, we're in the window where the estimates are firming up but the official number hasn't yet been announced.
The current estimates:
As of mid-September 2026, the leading estimates for the 2027 COLA are in the mid-3% range. Recent projections have clustered around 3.5% to 3.6%, based on inflation data through August. The Senior Citizens League projects a 3.5% Social Security COLA, which would increase average monthly benefit checks by an estimated amount, while AARP forecasts a 3.6% COLA for 2027. These estimates have moved around over the year as inflation data came in. CNBC
How this compares:
If the 2027 COLA lands in the mid-3% range, it would be a step up from recent years. The 2026 COLA was 2.8%, and a mid-3% increase would represent the largest percentage increase in benefits since 2023. It would also come in above the long-term average COLA, which has historically been closer to the mid-2% range. The Motley Fool
Why it's still an estimate:
It's important to understand these are estimates, not the final number. The COLA is based on the average CPI-W (a measure of inflation) during July, August, and September, and as of early-to-mid September, two of the three months of data are in, with one month remaining. Energy and gasoline prices through the rest of September are the single biggest swing factor left, so the final number could still move.

When it becomes official:
The SSA is expected to announce the official 2027 COLA in mid-October 2026, after September's inflation data is released. Until then, the estimates are a useful planning guide, but not a guarantee. Federal Employees Group Life Insurance
For Columbus-area retirees, the takeaway right now is that the 2027 COLA is trending toward one of the larger increases in recent years — but the number to plan around is the official one coming in October, and, as we'll see, the headline percentage isn't the whole story.
What a COLA Is and How It's Calculated
Before going further, it helps to understand what the COLA actually is and how the number is determined.
What the COLA does:
The cost-of-living adjustment is an annual increase to Social Security benefits designed to help them keep pace with inflation. The purpose of the COLA is to ensure that the purchasing power of Social Security benefits is not eroded by inflation. Without it, the fixed benefit would lose value every year as prices rise. Social Security Administration
How it's calculated:
The COLA is based on the percentage increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of the last year a COLA was determined to the third quarter of the current year. In practical terms, the government compares CPI-W inflation over the July–September period year-over-year, and that percentage becomes the COLA. Social Security Administration
Why the timing works the way it does:
Because the calculation uses July, August, and September data, the official COLA can't be finalized until September's numbers are in — which is why the announcement comes in mid-October each year. The estimates you see before then are projections based on the data available so far.
A known critique:
It's worth noting a common critique: the CPI-W measures inflation for urban wage earners and clerical workers, not specifically for retirees. Some retirees find these increases don't keep pace with their own personal expenditures' inflation, in part because the SSA calculates COLAs using the CPI-W rather than a measure focused on the spending of older Americans. Retirees tend to spend more on categories like healthcare, which can rise faster than the overall index — one reason a COLA can feel like it falls short. UBS
For Columbus-area retirees, understanding that the COLA is a measured, inflation-based adjustment — calculated a specific way, on a specific timeline — helps set realistic expectations about what it is and isn't designed to do.
The Nuance Most People Miss: Your Net Raise
Here's the most important point in this article, and the one most coverage glosses over: the COLA percentage is not your real raise. For retirees on Medicare, what actually lands in your monthly deposit is the COLA minus your Medicare premium increase.
Why the headline number misleads:
When you read "the COLA is 3.5%," it's natural to assume your benefit goes up 3.5% and that's what you'll see. But for the majority of retirees — those who are also on Medicare — it's not that simple, because of how Medicare premiums are paid.
The direct deduction:
For most Medicare enrollees, premiums are deducted directly from their Social Security payments. This means your Medicare Part B premium comes right out of your Social Security check before it reaches you. So when Medicare premiums rise, that increase eats into your COLA. AARP
The "net COLA" concept:
Your real raise — what actually increases in your deposit — is the net COLA: the gross COLA increase minus the increase in your Medicare premium. If your benefit goes up by the COLA, but your Medicare premium also goes up, the net effect on your deposit is the difference between the two.
A simple illustration:
Imagine a retiree's benefit rises by the COLA amount, but their Medicare Part B premium also increases. The premium increase is deducted from the higher benefit, so the net increase they see is the COLA raise minus the premium increase. The bigger the Medicare premium increase relative to the COLA, the smaller the net raise. In some years, a large Medicare premium increase can consume a meaningful chunk of the COLA.
Why this matters:
Focusing only on the headline COLA can lead to disappointment when the actual deposit increase is smaller. Understanding the net COLA gives you a realistic picture of what to expect — and it's a nuance that most retirees, and most news coverage, overlook.
For Columbus-area retirees, this is the key insight: watch the net COLA, not just the headline percentage. Your real raise is what's left after Medicare premiums, and that's the number that affects your actual income.
How Medicare Premiums Eat Into the COLA
To make the net-COLA concept concrete, it helps to look at how Medicare premium increases have been affecting retirees — and why 2027 is worth watching on this front too.
The recent Part B increase:
For 2026, the Medicare Part B increase was significant. The base rate for Medicare Part B — which covers doctor visits and other outpatient care — rose 9.7% for 2026, from $185 to $202.90 a month. Because most enrollees' premiums are deducted directly from their Social Security payments, that Part B increase effectively reduced their COLA. AARPAARP
Why the Medicare increase matters so much:
When the Medicare premium rises by a larger percentage than the COLA, it takes a real bite. A 9.7% jump in Part B premiums, against a 2.8% COLA in 2026, meant that Medicare's increase consumed a notable share of that year's raise for many retirees. This is exactly the net-COLA dynamic in action.
What's projected for 2027:
For 2027, Medicare Part B premiums are also expected to rise, though the official figure isn't set yet. Based on the 2026 Medicare Trustees Report, the standard Part B premium is projected to increase from $202.90/month in 2026 to approximately $209.50/month in 2027, though the official premium is set by the Centers for Medicare & Medicaid Services later in the year and can differ from this projection — some private forecasters expect the final number to land higher. Federal Employees Group Life Insurance
The net effect for 2027:
If the 2027 COLA lands in the mid-3% range and the Part B premium increase is more modest (in percentage terms) than 2026's, the net COLA for 2027 could be more favorable than 2026's was — meaning more of the raise actually reaches retirees' deposits. For a retiree receiving the average benefit, a mid-3% COLA minus the projected Part B increase would leave a net increase that's meaningful, though less than the gross COLA. But the final Medicare number matters, and it isn't set yet. Federal Employees Group Life Insurance
The both-numbers point:
The bottom line: to understand your 2027 raise, you need both numbers — the COLA (announced mid-October) and the Medicare Part B premium (announced by CMS later in the fall). Only together do they tell you your real, net increase.
For Columbus-area retirees, watching both the COLA and the Medicare Part B premium — and focusing on the net effect — is how you'll know what your 2027 raise really amounts to.
Why the COLA Rarely Feels Like Enough
Many retirees find that even a decent COLA doesn't feel like enough to keep up. Understanding why helps set realistic expectations and informs your planning.
Reason 1: The net-COLA effect.
As covered, Medicare premium increases reduce the COLA for those on Medicare, so the raise that reaches your deposit is smaller than the headline. This is a major reason the COLA often feels smaller than advertised.
Reason 2: The CPI-W mismatch.
The COLA is calculated using the CPI-W, which reflects the spending of urban wage earners, not retirees. Retirees typically spend more on healthcare and housing — categories that can rise faster than the overall index — so their personal inflation may outpace the COLA. The adjustment is designed to track a general inflation measure, not each retiree's specific costs. UBS
Reason 3: Healthcare inflation:
Healthcare costs, a large and growing part of many retirees' budgets, often rise faster than general inflation. Since the COLA tracks general inflation, it may not fully cover retirees' rising healthcare costs — and, via Medicare premiums, healthcare inflation directly reduces the net COLA.
Reason 4: It's a maintenance mechanism, not a raise:
Perhaps most importantly, the COLA is designed to help benefits maintain purchasing power against inflation — not to increase your standard of living. It's meant to keep you even, not to get you ahead. When retirees hope the COLA will improve their situation, they're expecting something it isn't designed to do. At best, it keeps pace; it's not a real raise in the sense of increased buying power.
The realistic frame:
Understanding these reasons helps set realistic expectations: the COLA is a valuable inflation-protection mechanism (Social Security is one of the few income sources that adjusts for inflation), but it's not designed to make you better off, and its net effect is often smaller than the headline. Appreciating what it is — and isn't — prevents disappointment and informs better planning.
For Columbus-area retirees, recognizing why the COLA rarely feels like enough — the net effect, the CPI-W mismatch, healthcare inflation, and its purpose as a maintenance mechanism — leads to more realistic expectations and better planning around it.
What This Means for Your Plan
Beyond understanding the COLA itself, it's worth considering what it means for your broader retirement plan.
Social Security's inflation protection is valuable:
First, an appreciation: Social Security's COLA is a genuinely valuable feature. It's one of the few sources of retirement income that automatically adjusts for inflation, providing inflation-protected, guaranteed income for life. This inflation protection is worth a great deal, especially over a long retirement — and it's a reason to value (and, where possible, maximize) your Social Security benefit. (I cover Social Security claiming strategies in my income planning content.)
The COLA doesn't cover everything:
But since the COLA is a maintenance mechanism (and its net effect is reduced by Medicare), you can't rely on it to grow your income or fully cover rising costs — particularly healthcare. Your broader plan needs to account for this: your portfolio and other income sources need to provide the growth and flexibility that Social Security's COLA doesn't.
Why your portfolio still needs growth:
This connects to investing during retirement: because Social Security's COLA only maintains purchasing power (and imperfectly, for retirees), your investment portfolio needs to provide real growth to keep up with your rising costs over a long retirement. This is a key reason retirees still need growth-oriented investments, not just "safe" ones. (I cover this in my investing during retirement content.)
Healthcare planning matters:
Since healthcare costs are what most erode the net COLA (through Medicare premiums) and often outpace it, planning for healthcare costs is essential. Understanding Medicare, budgeting for healthcare, and coordinating it with your income plan all matter. (I cover healthcare in retirement in a dedicated series.)
The coordinated view:
The COLA is one piece of a larger income picture. How it fits with your portfolio withdrawals, other income, taxes, and Medicare premiums is what determines your actual financial situation. Rather than focusing on the COLA in isolation, the better approach is understanding how it fits your whole plan.
For Columbus-area retirees, the COLA is a valuable but partial piece of the picture — appreciate its inflation protection, but ensure your broader plan (portfolio growth, healthcare planning, coordinated income) accounts for what the COLA doesn't cover.
When the Official Number Arrives
Since the official COLA is coming soon, here's what to expect and how to respond when it does.
The timeline:
The SSA is expected to announce the official 2027 COLA in mid-October 2026, after September's inflation data is released. The Medicare Part B premium for 2027 is typically announced by CMS later in the fall. So over the coming weeks, both key numbers should become official. Federal Employees Group Life Insurance
What to do when the COLA is announced:
- Note the official figure — see how it compares to the current estimates
- Wait for the Medicare number too — remember, the COLA alone isn't your net raise
- Calculate your net increase — once both numbers are known, you can estimate your actual deposit increase (COLA minus any premium increase)
- Update your planning — factor the net increase into your income and budget
Where you'll see your specific number:
For Social Security beneficiaries receiving Medicare, the new benefit amount will be available in December through the mailed COLA notice and the my Social Security online account's Message Center. That's when you'll see your specific, personal net figure. Social Security Administration
Don't overreact to the headline:
When the COLA is announced, there will be plenty of headlines. Remember that the headline percentage isn't your net raise, and that the COLA is one piece of your plan. A calm, informed response — noting the number, waiting for the Medicare figure, calculating your net increase, and fitting it into your plan — beats reacting to the headline.
Where I can help:
When the numbers are official, I'm glad to help Columbus-area clients understand what their net COLA means for their specific situation and how it fits their overall income and healthcare plan.
For Columbus-area retirees, the practical approach is: watch for the official COLA in mid-October and the Medicare premium later in the fall, calculate your net increase once both are known, and fit it into your broader plan — rather than reacting to the headline number.
Putting the COLA in Perspective
Finally, it's worth putting the COLA in proper perspective — neither overvaluing nor dismissing it.
What the COLA is:
- A valuable inflation-protection feature of Social Security
- An annual adjustment to help benefits keep pace with (general) inflation
- One of the few sources of inflation-adjusted, guaranteed retirement income
- Currently trending toward a mid-3% increase for 2027, among the larger in recent years
What the COLA isn't:
- A real raise that improves your standard of living
- A number that reaches your deposit in full (Medicare premiums reduce it)
- A guarantee to cover retirees' specific inflation (especially healthcare)
- The whole story of your retirement income
The balanced view:
The COLA is genuinely valuable — inflation-adjusted guaranteed income is a real benefit that many other income sources don't provide. But it's also limited: it maintains rather than improves, its net effect is smaller than the headline, and it's one piece of a larger plan. Both appreciating it and understanding its limits leads to the most realistic perspective.
The bottom line for 2027:
For 2027, retirees are on track for one of the larger COLAs in recent years (currently estimated in the mid-3% range), which is welcome news. But the net figure — after Medicare premiums — is what will actually land in your deposit, and how it fits your overall plan is what matters most. Watch both numbers, focus on the net effect, and keep the COLA in perspective as one valuable-but-partial piece of your retirement income.
For Columbus-area retirees, keeping the COLA in perspective — valuable but limited, maintenance not improvement, net not headline — is the key to responding to it wisely as the official 2027 numbers arrive this fall.
Frequently Asked Questions
What is the 2027 Social Security COLA?
The 2027 cost-of-living adjustment is currently estimated in the mid-3% range — recent projections put it around 3.5% to 3.6%, based on inflation data through August 2026. That would be up from the 2.8% COLA for 2026 and among the larger increases in recent years. These are estimates; the official number is expected from the SSA in mid-October 2026.
When will the official 2027 COLA be announced?
The Social Security Administration is expected to announce the official 2027 COLA in mid-October 2026, after September's inflation data is released. The COLA is based on CPI-W inflation over July, August, and September, so it can't be finalized until September's data is in. The Medicare Part B premium for 2027 is typically announced by CMS later in the fall.
Is the COLA percentage my actual raise?
Not for most retirees. If you're on Medicare, your Part B premium is typically deducted directly from your Social Security payment — so your real raise is the "net COLA": the COLA increase minus any Medicare premium increase. The headline COLA percentage overstates what actually lands in your deposit for those on Medicare.
How do Medicare premiums affect my COLA?
Because Medicare Part B premiums are usually deducted directly from Social Security payments, a premium increase reduces your net COLA. For example, the 2026 Part B premium rose 9.7% (from $185 to $202.90/month), which consumed a share of the 2026 COLA for many retirees. To know your real 2027 raise, you need both the COLA and the Medicare premium figures.
How is the COLA calculated?
The COLA is based on the percentage increase in the CPI-W (Consumer Price Index for Urban Wage Earners and Clerical Workers) from the third quarter of the prior year to the third quarter of the current year — essentially comparing July–September inflation year-over-year. Because it uses September data, the official number comes out in mid-October.
Why does the COLA never seem like enough?
Several reasons: Medicare premium increases reduce the net COLA; the CPI-W reflects urban workers' spending, not retirees' (who spend more on healthcare, which rises faster); healthcare inflation often outpaces general inflation; and the COLA is designed to maintain purchasing power, not improve your standard of living. It keeps you even at best, not ahead.
Will the 2027 COLA be bigger than 2026's?
Current estimates suggest yes — the 2027 COLA is trending in the mid-3% range, versus the 2.8% COLA for 2026, which would make it among the larger increases in recent years. But these are estimates, and the official number isn't set until mid-October. The net effect will also depend on the 2027 Medicare Part B premium.
Does everyone's Medicare premium come out of Social Security?
For most Medicare enrollees who also receive Social Security, yes — Part B premiums are typically deducted directly from the Social Security payment. Not everyone on Social Security is on Medicare (Medicare generally starts at 65, and some claim Social Security earlier), and higher earners pay higher Medicare premiums (IRMAA), but for the typical retiree on both, the premium comes out of the benefit.
How should the COLA factor into my retirement plan?
Appreciate it as valuable inflation-protected guaranteed income, but don't rely on it to grow your income or cover all rising costs (especially healthcare). Because it only maintains purchasing power — and imperfectly for retirees — your portfolio and other income need to provide real growth and flexibility. The COLA is one valuable-but-partial piece of a coordinated income plan.
Where will I see my specific new benefit amount?
For Social Security beneficiaries on Medicare, the new benefit amount (reflecting both the COLA and the Medicare premium) will be available in December, through the mailed COLA notice and the my Social Security online account's Message Center. That's when you'll see your specific, personal net figure for 2027.
Watch the Net Number, Not Just the Headline
For Columbus-area retirees, the 2027 Social Security COLA is trending toward one of the larger increases in recent years — currently estimated in the mid-3% range, up from 2.8% for 2026, with the official number expected in mid-October. That's welcome news. But the most important thing to understand is that the headline COLA isn't your real raise.
The pattern that produces a realistic picture: remember that for those on Medicare, the net COLA — the increase minus rising Medicare premiums — is what actually lands in your deposit; watch both the COLA (mid-October) and the Medicare Part B premium (later this fall) to know your true 2027 raise; recognize that the COLA is a maintenance mechanism, not a real raise, and that it may not keep up with retirees' specific costs; and fit it into your broader plan, where your portfolio and other income provide the growth the COLA doesn't.
The goal isn't to celebrate or lament the headline number — it's to understand your real, net increase and how it fits your overall retirement income. The COLA is a valuable piece of inflation-protected income, but it's one piece of a larger plan.
As the official 2027 numbers arrive this fall, I'm glad to help Columbus-area clients understand what their net COLA means for their specific situation and how it fits their coordinated income, healthcare, and investment plan.
