If you’ve seen three or four different numbers for your 2027 Social Security raise this month, you’re not losing track of anything. First it was 4.7%. Then 3.7%. Then 3.8%, with 3.6% right beside it. Here’s the honest reason none of those agree: right now, none of them is the actual number. They’re all careful, credible estimates from named forecasters – and the part almost every headline leaves out is that Medicare takes its own cut before that raise ever reaches your bank account.

This is written in mid-July 2026, the same week one of those estimates got revised again. So before anything else, let’s separate what’s actually known from what’s still a forecast, then do the part the headlines skip: the real arithmetic of what you’d actually get to keep, once Medicare’s Part B premium comes out.

If you’re reading this because a parent called asking whether one of those headline percentages was true, you’re in the right place too. For a lot of Gleemo readers, this isn’t an abstract number – it’s next January’s actual bank deposit, for you or for someone you’re helping keep track of theirs.

This article is general information, not personalized financial, tax, or legal advice – Gleemo is not a financial advisor or the Social Security Administration. Every 2027 figure in this piece is an estimate as of July 2026: the Social Security Administration won’t confirm the actual COLA until an expected mid-October 2026 announcement, and Medicare won’t confirm the actual Part B premium until an expected November 2026 announcement. Check ssa.gov and medicare.gov for the official numbers, or talk to a free SHIP counselor, before making any financial decisions based on next year’s raise.

Why Every Headline About Your 2027 Raise Says a Different Number

Here’s what’s actually happening behind the whiplash. Your annual raise – officially the cost-of-living adjustment, or COLA – isn’t announced until October, so anyone reporting a number right now is necessarily reporting a forecast, not a fact. As of mid-July 2026, four separate, named forecasters each have a current, published estimate, and none of them are wild outliers relative to each other.

Three-tenths to four-tenths of a percentage point isn’t much to argue over on its own. But when a number tied to your income keeps shifting and nobody explains why, it can feel like the ground is moving. It isn’t – it’s just still being measured, and the measurement finishes in October. This piece sits at the crossroads of two worries a lot of us carry into our sixties: will I have enough, and why does healthcare keep taking more. The honest answer to both starts with knowing exactly what’s confirmed, what’s estimated, and what Medicare does before you ever see the deposit.

How the COLA Is Actually Calculated (and Why It Can’t Be Official Until October)

The COLA isn’t a decision anyone makes in a meeting. It’s a formula, written into law, that runs on its own once the data exists.

By law, the Social Security Administration compares average inflation – specifically the CPI-W, the Consumer Price Index for Urban Wage Earners and Clerical Workers, a Bureau of Labor Statistics measure – across July, August, and September of this year against the same three months from the prior comparison period. Whatever that comparison produces becomes next year’s COLA. The law also requires SSA to announce the result before November 1 each year.

The catch is timing: two of those three months, August and September 2026, haven’t happened yet as this is being written. That’s exactly why every estimate you’re reading right now – including the ones in this piece – is built from partial data plus a forecast for the missing summer months. October 14, 2026 is the date widely expected for the official announcement, based on the Bureau of Labor Statistics’ usual release schedule – but it is not yet confirmed by SSA. More on why that date itself carries some real uncertainty further down.

The Current Estimates, Explained: Who’s Saying What, and Why the Number Just Dropped a Point

As of mid-July 2026, here’s exactly who’s estimating what, and when they said it:

• AARP: 3.6%, published July 14, 2026
• Mary Johnson, an independent Social Security and Medicare policy analyst: 3.7%, published July 14, 2026 – revised down from her own 4.7% estimate a month earlier
• The Senior Citizens League (TSCL): 3.8%, holding since June 2026
• The Committee for a Responsible Federal Budget (CRFB) – a nonpartisan budget research group, not the Congressional Budget Office, despite the similar name: 3.8% as a central estimate, with a stated range of 3.0%-4.5% (published May 2026, and may not yet reflect the summer’s cooling inflation data)

Put together, current estimates cluster at roughly 3.6%-3.9%. Every one of those numbers is labeled “estimated.” None is “confirmed.”

It’s worth slowing down on Mary Johnson’s revision, because it’s a real, dated example of how fast these numbers move. Her earlier 4.7% figure – which you may still see quoted in older articles – is a full percentage point higher than her current estimate, and it’s already superseded by her own more recent number. The change followed a June 2026 inflation report that came in cooler than expected, helped along by falling energy prices. That’s the process working correctly, not anyone getting it wrong – and it’s a fair warning that any of today’s four estimates could still move again before October.

The Part the Headlines Skip: Medicare Comes Out First

If part of you already suspects “Medicare is just going to take it anyway,” you’re onto something real – just not quite as bleak as it sounds.

If you’re enrolled in Medicare, your Part B premium – the part that covers doctor visits and outpatient care – is typically withheld directly from your Social Security check before it’s ever deposited. You don’t see that money arrive and then leave separately. It simply isn’t there when the deposit posts.

The 2026 Part B premium is confirmed and final: $202.90 a month, up $17.90 (about 9.7%) from $185.00 in 2025.

For 2027, the number getting quoted most often – $209.50 a month – comes from the government’s own 2026 Medicare Trustees Report, published June 9, 2026. That is a projection, not a confirmed premium. The Centers for Medicare & Medicaid Services (CMS) won’t confirm the actual 2027 Part B premium until roughly November 2026.

Some independent forecasters expect the real number to land higher instead, in the $216-$219 range. That estimate comes from a different source, with a lower-confidence, unattributed methodology, and it should be weighed differently than the government’s own $209.50 projection – never averaged together with it. Worth knowing, too: there’s no reliable track record pointing either direction here. The prior year’s Trustees Report actually overestimated the following year’s real premium by $3.60, so “the government always projects low” isn’t a safe assumption to lean on.

What You Actually Kept in 2026 (a Real, Confirmed Example) – and What 2027 Could Look Like

Here’s a real, fully confirmed example worth anchoring on, because it shows exactly how this math plays out once both numbers are final.

The 2026 COLA was 2.8%, official and final, which raised the average retired-worker benefit from $2,015 to $2,071 a month – a confirmed $56 increase. That same January, the Part B premium rose $17.90. Net result: $38.10 a month left over once Medicare’s increase came out – about 68% of the raise. Medicare’s cut consumed the other 32%.

Now, the 2027 picture – and every figure here is still an estimate, as of July 2026, not a confirmed number. Using the Social Security Administration’s own $2,071 baseline and the current 3.6%-3.9% estimate range, the computed gross raise comes to about $74.56-$80.77 a month. If the Part B premium lands at the government’s own $209.50 projection, that’s a $6.60 monthly increase, leaving a net kept amount of about $68-$74 a month – roughly 91%-92% of the raise.

If those numbers hold, 2027 would be the first year since 2023 that the raise’s percentage growth actually outpaces Medicare’s. That’s a real, hopeful possibility – but it isn’t settled. It only holds if Part B lands near $209.50. If it lands in the $216-$219 range some independent forecasters expect instead, that favorable gap shrinks, and the more familiar pattern – Medicare outpacing the raise – continues. Both the COLA and the Part B premium remain estimates until their official announcements in October and November.

Your own numbers will differ. The math above uses the SSA’s average benefit as a stand-in – your actual benefit, premium, and which protections apply to you depend on your own earnings record, income, and enrollment status. To get a closer personal estimate, multiply your own current check by the estimate percentage, keeping in mind it isn’t official until October.

Note: 2027 figures are estimates only, as of July 2026 – none are official. SSA is expected to confirm the 2027 COLA in mid-October 2026; Medicare is expected to confirm the 2027 Part B premium around November 2026. The $209.50 and $216-$219 figures come from two different sources and should never be averaged. Verify the final numbers at ssa.gov and medicare.gov once announced.

Who This Hits Differently: Modest Earners, SSI/Medicaid Recipients, and Higher Earners on IRMAA

The math above uses the average benefit, but “average” hides some real differences worth naming honestly.

Consider a smaller check – say, $1,400 a month, just above the roughly $1,350-a-month income cutoff for Medicare Savings Programs (more on those next). If the $209.50 Part B estimate holds, the same flat $6.60 increase that eats about 8%-9% of the average earner’s raise eats about 12%-13% of that smaller raise. A flat-dollar increase is, by definition, a bigger percentage bite on a smaller number.

Here’s a common assumption worth correcting directly: this does not mean the Part B increase hits the poorest retirees hardest. Most people receiving Supplemental Security Income (SSI) are also dual-eligible for Medicaid, which typically pays their Part B premium automatically. That means the lowest-income beneficiaries usually don’t feel this specific increase directly at all. (The 2026 SSI federal benefit rate is $994 a month for an individual.) The heaviest percentage bite actually lands on people with modest, but not rock-bottom, incomes – earning too much to qualify for that help, but not enough for a flat $6.60 increase to feel small.

At the other end, higher earners pay more to begin with, through IRMAA, the income-related monthly adjustment amount added on top of the standard premium. In 2026, IRMAA applies above $109,000 (single) or $218,000 (married filing jointly) in income, and pushes the Part B premium as high as $689.90 a month – a much larger dollar exposure than the standard-premium math above, and one IRMAA payers should track separately.

One more group worth naming here: the “hold harmless” provision protects most existing beneficiaries from a net dollar decrease in their check due to a Part B increase – but it does not protect new Medicare Part B enrollees, people billed directly for Part B rather than through Social Security withholding, or people who pay IRMAA. If you fall into one of those three groups, hold harmless was never built to help you.

Free Help If Medicare’s Premium Is Squeezing You

Before you assume you’re stuck absorbing whatever the Part B increase turns out to be, it’s worth ten minutes to check whether help already exists.

Medicare Savings Programs – there are three, known as QMB, SLMB, and QI – can eliminate the Part B premium entirely for beneficiaries with roughly $1,350 a month or less in individual income (the exact limit varies somewhat by state). Enrolling in any of them also automatically triggers Extra Help with Part D prescription drug costs. These programs are active now, in 2026, and you apply through your state’s Medicaid agency.

If you’d rather talk it through with a real person, every state has a SHIP – State Health Insurance Assistance Program – office offering free, one-on-one Medicare counseling, with no income limit to qualify. It’s active in every state in 2026, and it costs nothing to call.

What Could Still Change This Estimate Before October (and How to Get the Real Number Yourself)

Every number above is a snapshot as of mid-July 2026. A few real things could still move it before October, and it’s worth knowing what they are instead of just watching headlines shift.

Energy prices could push estimates back up. Part of what cooled the estimates you’re reading right now was falling energy prices during an Iran ceasefire. That ceasefire ended on July 8, 2026, and oil prices jumped more than 5% that same day. If energy prices stay elevated through the July-September 2026 measurement window, the eventual COLA could land above today’s estimates. The July inflation data, due out in mid-August 2026, will be the first real read on whether that’s happening.

A government shutdown could delay the announcement itself. October 14, 2026 is the widely expected date for the official COLA announcement – not a confirmed one. The equivalent 2025 announcement was expected in mid-October and actually slipped nine days, to October 24, because of a federal government shutdown that suspended data collection. A new shutdown risk exists at the September 30, 2026 federal funding deadline: as of July 2026, only 2 of the 12 annual appropriations bills had passed the full House, and the Senate had passed none. No shutdown has hit this specific deadline yet, but the government already shut down twice earlier in 2026 over an unrelated dispute – so this is a real, live possibility, not a hypothetical one.

The Part B premium could land above or below $209.50. CMS’s actual fall rate-setting process uses newer data than the mid-year Trustees Report, and it can move the final number in either direction – no signal yet on which way 2027 will go.

When the real numbers do land, here’s where to get them straight from the source, without needing to do any math yourself: the Social Security Administration posts the official COLA at ssa.gov, and mails a COLA notice each December, with the new amount also visible in your own my Social Security online account (ssa.gov/myaccount) before the January payment. Medicare posts the confirmed Part B premium at medicare.gov once CMS finalizes it, expected around November 2026.

One more honest piece of context, separate from the estimate-versus-confirmed distinction above: The Senior Citizens League’s own 2026 research – their own methodology, not a government statistic – found that Social Security benefits have lost 13.7% of their buying power since 2016, and would need an additional $295.85 a month (15.7%) to fully restore it. That’s not a claim about this year’s raise specifically; it’s a longer-running argument about whether the COLA formula keeps pace with what retirees actually spend. Worth knowing, even though it’s advocacy research, not an official government finding.

The Bottom Line

Here’s what’s worth telling a parent, or reminding yourself, if one of these headlines lands in your inbox again before October: nobody can hand you a final number yet, and anyone telling you otherwise is guessing louder, not knowing more. But you don’t need the final number to feel steady.

You need the range – 3.6%-3.9%, as of today. You need the mechanism – Medicare comes out of the check before you ever see it. You need to know where you personally fall – standard withholding, a new enrollee, or an IRMAA payer, since that changes which protections apply to you. And you need two dates: October, for the COLA, and November, for Medicare.

This was never really about a percentage. It was about handing you back a sense of steady, informed footing on your own numbers, so you can stop refreshing the news and start planning once the real ones arrive.

Frequently Asked Questions

When will the 2027 Social Security COLA be announced?

October 14, 2026 is the date widely expected for the official announcement, based on the Bureau of Labor Statistics’ usual release schedule – but it is not yet confirmed by the Social Security Administration. By law, SSA must announce before November 1. The equivalent 2025 announcement was expected in mid-October and actually slipped nine days, to October 24, due to a government shutdown – and a new shutdown risk exists at the September 30, 2026 federal funding deadline.

How much will my Social Security check increase in 2027?

As of mid-July 2026, four named forecasters have current estimates clustering between 3.6% and 3.9% – AARP at 3.6%, independent analyst Mary Johnson at 3.7%, The Senior Citizens League at 3.8%, and the Committee for a Responsible Federal Budget at 3.8% central, with a wider possible range of 3.0%-4.5%. None of these is official. Using the Social Security Administration’s own $2,071 average retired-worker benefit and that estimate range, the computed gross raise comes to about $74.56-$80.77 a month, before Medicare’s Part B premium comes out.

Will Medicare eat my Social Security raise in 2027?

Not entirely, based on current estimates – though it will take a real bite. If the Part B premium lands near the government’s own $209.50 projection, a beneficiary at the average benefit would keep roughly 91%-92% of their raise, about $68-$74 a month, after the Part B increase. That would be a better outcome than 2026, when only about 68% of that year’s raise survived Medicare’s cut. If Part B instead lands in the $216-$219 range some independent forecasters expect, that favorable math shrinks. Both figures remain estimates until their October and November 2026 announcements.

What is the Social Security hold harmless provision, and does it protect me?

Hold harmless protects most existing beneficiaries’ net Social Security payment from going down because of a Medicare Part B increase. It does not protect three groups: people newly enrolled in Medicare Part B, people who are billed directly for Part B rather than having it withheld from a Social Security check, and people who pay IRMAA, the income-related surcharge added on top of the standard premium.

How can I get help paying my Medicare Part B premium?

Medicare Savings Programs (QMB, SLMB, and QI) can eliminate the Part B premium entirely for beneficiaries with individual income of roughly $1,350 a month or less in 2026 (the exact limit varies by state), and enrolling also triggers automatic Extra Help with Part D drug costs. For free, one-on-one help figuring out your own situation, every state has a SHIP counselor available at no cost, with no income limit.
