Social Security COLA Announcement October 14: Time, What to Expect and Medicare Open Enrollment Checklist

Social Security COLA Announcement October 14: The next Social Security raise will be revealed on Wednesday, October 14, when the Bureau of Labor Statistics publishes September inflation data at 8:30 a.m. Eastern. That single percentage sets the 2027 cost-of-living adjustment for tens of millions of retirees, disabled workers and survivors. Forecasters are bunched between 3.2 percent and 3.6 percent, and the Senior Citizens League settled on 3.5 percent in its final September call. If that number holds, the average benefit would rise by roughly $68 a month, although Medicare Part B is expected to take back a slice of it. Less than 24 hours later, on Thursday, October 15, Medicare open enrollment begins and runs through December 7. This guide covers the Social Security COLA announcement time, what to expect in your check and a practical Medicare open enrollment checklist. We’ll be updating this article monthly.

The stakes feel higher this year because last year’s raise was smaller and costs have not eased. The 2026 adjustment was 2.8 percent, yet a $17.90 jump in the Part B premium swallowed about a third of the average gain, according to the Senior Citizens League. Wage-earner inflation, the CPI-W index that drives the formula, ran at 3.4 percent in July and 3.5 percent in August on a year-over-year basis, according to figures reported by Kiplinger. Two of the three months that count are already in the books, so the September reading mostly decides whether the final answer lands at 3.4, 3.5 or a notch higher. Benefit notices go out in December, and the larger payment arrives starting in January 2027. Below you will find the key dates, dollar examples, a free calculator, official links and the choices Medicare enrollees must make in the next seven weeks.

Social Security COLA Announcement Time and Key Dates

The inflation report is the trigger. BLS lists the September 2026 Consumer Price Index for Wednesday, October 14, 2026 at 8:30 a.m. Eastern, which is 7:30 a.m. Central, 6:30 a.m. Mountain and 5:30 a.m. Pacific. The Social Security Administration has historically posted its COLA announcement the same morning, though the exact minute can vary and we could not confirm a published SSA time for this year. Check ssa.gov/cola on the day.

The Social Security Administration usually releases the new taxable maximum and other 2027 program figures around the same time as the COLA. We could not verify those numbers ahead of the announcement, so this article will be updated once they are official.

How the 2027 Social Security COLA Is Calculated

The Social Security COLA formula is simple, and knowing it helps you read the headline correctly. Social Security uses the CPI-W, the price index for urban wage earners and clerical workers. It averages the readings for July, August and September of the current year and compares that average with the same three-month average a year earlier. The percentage gain, rounded to the nearest tenth, becomes the COLA. If prices fell, the COLA would simply be zero, because the formula never produces a cut.

That is why the September report matters but does not stand alone. With July and August already published, the third month adds the last piece. A single unusually hot or cool September could move the final figure by a tenth or two, not by a full point. Gas and transportation prices late in the summer are the usual wild cards.

2027 COLA Forecast: What the Experts Expect

Treat every number above as a forecast. The official figure is the one SSA publishes on Wednesday. For perspective, the average COLA from 2017 through 2026 was 3.1 percent, with a high of 8.7 percent for 2023 and a low of 0.3 percent for 2017. A 3.5 percent raise would therefore sit modestly above the recent average but far below the post-pandemic spike.

What a 3.5 Percent COLA Means for Your Monthly Check

Dollar examples make the percentage real. The table shows the gross monthly increase at three forecast levels before Medicare premiums and taxes. Social Security rounds benefits down to the whole dollar, so your actual figure may differ by a few cents.

Averages differ by source, so be careful when you compare headlines. The Senior Citizens League uses an average benefit of $1,940.08, which at 3.5 percent produces a $67.90 monthly increase and a new average of $2,007.98. Kiplinger, working from a retired-worker average of $2,087.52, calculates a $73.06 increase to $2,160.58. Both are consistent with the same 3.5 percent forecast. They simply start from different baselines.

Medicare Part B and the COLA: How Much Will You Really Keep?

For most beneficiaries, the Part B premium comes straight out of the Social Security payment, so the raise on paper is not the raise in your bank account. The Medicare Trustees Report estimates that the 2027 standard Part B premium will rise by $6.60, from $202.90 to $209.50 a month. The official premium is expected from CMS in November and could come in higher.

The Part D deductible and cap are described as set by a statutory formula in reporting published in early October, while the Part B numbers remain estimates until CMS confirms them. Our own arithmetic shows the Part B bump would absorb about 9 percent of a $70 raise and about 13 percent of a $52.50 raise, so lower-benefit households feel it more. Longer term, the 2026 Trustees Report projects the Part B premium could reach $360.60 by 2035, a 77.7 percent increase from 2026.

Social Security COLA Calculator: Estimate Your 2027 Raise

Use the calculator below to test different outcomes before Wednesday and then re-run it with the official percentage. It estimates your new gross benefit, your monthly and yearly gain, and how much of the raise a higher Part B premium could consume. It runs in your browser and stores nothing. The result is an estimate, and the Social Security Administration’s notice is the only official figure.

When Will the 2027 Social Security COLA Show Up in Your Payments?

Nothing changes in your account on announcement day. SSA sends COLA notices in December, and the higher benefit appears in payments starting in January 2027. Supplemental Security Income recipients typically see the new amount for January paid at the very end of December. If you have a my Social Security account, you can often read your notice online before the paper copy arrives, which is a handy way to see your new Part B deduction early.

Social Security Payment Schedule: Which Wednesday Do You Get Paid?

Most people who started benefits after May 1997 are paid on a Wednesday that depends on their birth date. If you were born between the 1st and 10th of the month, your payment lands on the second Wednesday. Birthdays between the 11th and 20th are paid on the third Wednesday, and birthdays between the 21st and 31st on the fourth Wednesday. People who began collecting before May 1997, and those who receive both Social Security and SSI, are generally paid on the 3rd of the month. When a payment date falls on a weekend or federal holiday, the money normally arrives on the prior business day. Because January 2027 begins with a holiday, check your own deposit date in your online account rather than assuming.

Medicare Open Enrollment 2026: Dates You Need to Know

Medicare open enrollment, formally called the annual enrollment period, runs from October 15 to December 7, 2026. Any change you choose takes effect on January 1, 2027. During this window, people with Original Medicare can join or switch a stand-alone Part D drug plan or move into a Medicare Advantage plan. People already in Medicare Advantage can switch to another plan or return to Original Medicare and add a drug plan. A separate Medicare Advantage open enrollment period runs January 1 to March 31 for people already in an Advantage plan, but it only allows certain changes, so December 7 is the safer deadline. Non-Medicare shoppers use a different calendar: Marketplace enrollment for 2027 runs November 1, 2026 through January 15, 2027, with a December 15 deadline for January 1 coverage.

Medicare Open Enrollment Checklist for 2027 Coverage

1. Read your Annual Notice of Change. Plans must send it by September 30, and it lists next year’s premium, deductible, copays and any plan changes. Many people never open it, and that is where surprises start.
2. Compare drug coverage, not just premiums. Enter every prescription, dose and your preferred pharmacy into the Medicare Plan Finder. Check tiers, prior authorization rules and whether the pharmacy is in the plan’s preferred network.
3. Confirm your doctors and hospitals are in network. If you use Medicare Advantage, call the offices directly and ask whether they will accept the plan next year, not only whether they accept it today.
4. Look at the total yearly cost. Add premiums, deductibles, copays and the maximum out-of-pocket limit. Original Medicare has no annual cap, while Medicare Advantage plans do.
5. Check the new Part D numbers. A $700 deductible and a $2,400 out-of-pocket cap are set for 2027, and some plans may offer lower deductibles.
6. Ask about Extra Help. The Low-Income Subsidy and Medicare Savings Programs can cut costs by thousands of dollars a year, yet many eligible people are not enrolled.
7. Review Medigap if you have it. Supplement premiums and underwriting rules vary by state, and open enrollment does not guarantee you can switch without a health review.
8. Watch for plan exits. Some insurers are trimming Medicare Advantage offerings, so a plan you like may change or disappear.
9. Talk to a free counselor. Every state has a State Health Insurance Assistance Program, and its counselors do not sell plans.
10. Keep proof. Save confirmation numbers, and when you enroll by phone, write down the date, time and agent name.

What Is Changing in Medicare for 2027?

Several changes make this a year to shop rather than coast. Fifteen more drugs, including GLP-1, cancer and diabetes medications, will carry lower negotiated prices in 2027, according to Yahoo Finance, although your copay may not fall by the same proportion. The temporary federal subsidy that lowered stand-alone Part D premiums by about $16 in 2026 is ending, and CMS announced in August that it is discontinuing the Part D Premium Stabilization Demonstration. Kiplinger reports that the projected average stand-alone Part D premium would still edge up only modestly, from $35.09 to $36.00, so individual plans may differ widely from the average. Large insurers are also scaling back Medicare Advantage offerings because of rising costs.

Also keep an eye on the Marketplace side if you or a spouse are under 65. Premiums there are expected to rise by double digits for a second year after enhanced tax credits expired, according to Justice in Aging, and eligibility rules for premium tax credits narrow for some lawfully present immigrants starting January 1, 2027.

How to Enroll or Change Your Medicare Plan

You do not have to start from scratch. The steps below work for most people during open enrollment.

1. Create or log in to your Medicare account, then open the Plan Finder at medicare.gov.
2. Enter your drugs and pharmacy, and compare plans by estimated total cost.
3. Choose a plan and enroll online, through the plan itself or by calling 1-800-MEDICARE.
4. Save the confirmation, and follow up if you do not receive a welcome packet or member ID card by late December.
5. If you are new to Medicare, remember that your initial enrollment period is separate from open enrollment and is based on your 65th birthday, so apply through the Social Security Administration.

Medicare Processing Time: When Do Changes Take Effect?

If you enroll or switch by December 7, your new coverage starts January 1, 2027. You do not need to cancel your old plan when you join a new one, because the new enrollment replaces it. If you submit more than one plan choice, the last one received before the deadline generally counts. Plans normally send a confirmation and member materials within a few weeks, but you should still contact the plan if nothing arrives, since a missing ID card is easier to fix in December than in January.

FAQs About the Social Security COLA Announcement

Conclusion

Wednesday’s report will answer the biggest Social Security question of the year, and the answer is likely to land close to 3.5 percent. The harder work starts the next day. A raise of $50 to $100 a month is welcome, but it can shrink if your Part B premium climbs or your drug plan changes. Treat the Social Security COLA announcement as the starting gun for a short, specific to-do list: confirm your new benefit when the notice arrives, compare plans before December 7, check your doctors and drugs, and ask a free counselor if anything looks confusing. Come back after the announcement, because we will update the figures here as soon as SSA and CMS publish them.
