Social Security COLA 2027: Your New Check, Explained

The Short Answer: 3.6% More, About $75 on Average — Before Medicare

On October 14, 2026, the Social Security Administration (SSA) announced a 3.6% cost-of-living adjustment (COLA) for 2027. The average retired worker’s benefit rises by about $75 a month, from $2,095 to $2,170. Nearly 72 million Social Security beneficiaries get the increase with January 2027 payments, and about 7.3 million Supplemental Security Income (SSI) recipients see it earlier, on December 31, 2026.

That is the headline. Your actual January deposit is a different number, and it is the one worth calculating. The 3.6% applies to your gross benefit, not to the amount that lands in your bank account. If Medicare Part B premiums come out of your check — as they do for most retirees — and if you have tax withholding or a Part D premium deducted, your deposit will rise by less than the gross increase. The good news this year is that the projected Medicare increase is small: the Medicare Trustees project Part B rising by just $6.60 a month, to $209.50, which would leave the average retiree with about $68.40 more per month after that premium. But that premium is not final yet — the Centers for Medicare & Medicaid Services (CMS) had not published the official 2027 Part B premium as of late October — so treat $68.40 as a projection, not a promise.

This article works out your new check at several benefit levels, explains how the COLA is calculated, lays out the exact notice and payment timeline, and covers the Medicare, tax, and scam issues that trip people up every year. Nothing here is professional financial advice; benefit rules have individual exceptions, and your SSA notice is the final word on your amount.

How Much Will Your Check Actually Rise?

Start with your current gross monthly benefit — the amount before deductions, which you can find on your last SSA notice or in your my Social Security account. Multiply it by 1.036. That is your new gross benefit.

* Net column assumes you pay the standard Part B premium from your check and that the projected $6.60 increase holds. If you do not have Part B deducted, if you pay an income-related surcharge, or if you have other deductions, your net change will differ. The $6.60 figure comes from the 2026 Medicare Trustees Report projection, not a final CMS announcement.

Two things about this table are worth pausing on. First, the same percentage produces very different dollars. A $1,200 benefit gains $43.20; a $2,800 benefit gains more than twice as much. Budgeting from the $75 average is a mistake if your benefit is well above or below it — always run your own number.

Second, the net column is where most people’s expectations go wrong. For years, Medicare Part B increases ate a large share of the COLA: the 2026 premium jumped $17.90, or 9.7%, against a 2.8% COLA. This year looks different. A projected 3.25% Part B increase ($6.60) against a 3.6% COLA would be the first year since 2023 in which the COLA outpaces the Part B increase in percentage terms. That is genuinely good news — if the projection holds. Watch for the official CMS announcement, expected in November, and re-run your number when it lands.

A related protection helps many retirees: the hold-harmless rule generally limits the dollar increase in the Part B premium to the dollar increase in the benefit for about 70% of Part B enrollees — those who have the premium deducted from their Social Security check and pay the standard premium. It matters most in years when the premium would otherwise rise more than the benefit. This year, with the projected premium rise smaller than most benefits’ COLA increase, it is less likely to bind — but it is still worth knowing it exists if your benefit is small.

How the 3.6% Was Calculated

The COLA is not set by Congress each year and it is not a political decision. By law, it follows the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published by the Bureau of Labor Statistics. Specifically, the SSA compares the average CPI-W for July, August, and September of the current year with the same three months of the previous year. The percentage increase becomes the next year’s COLA.

For 2027, that comparison produced 3.6%, up from 2.8% for 2026 and the largest COLA since the 8.7% increase in 2023. September 2026 consumer prices were up 3.7% from a year earlier, and higher energy prices in the summer months helped push the third-quarter average up. That is also why the number can feel disconnected from your own spending: CPI-W tracks the spending of urban wage earners and clerical workers, not retirees. Retirees tend to spend proportionally more on health care and housing, which is why some analysts argue for an experimental retiree index (CPI-E) instead. Congress has not adopted it, so CPI-W remains the law — and this year, energy-driven inflation actually gave retirees a raise above their health-care-heavy inflation in some measures, which is the opposite of the usual complaint.

One practical consequence: because the COLA is automatic, you do not need to apply for it, call SSA, or fill out a form. If you receive Social Security or SSI, it applies to you. Anyone asking you to pay a fee or submit an application to “claim” your COLA is running a scam (more on that below).

When the Money Arrives: Dates and Notices

The timing depends on which benefit you receive:

For Social Security payments, the day of the month follows the usual schedule based on your birth date: birthdays on the 1st through the 10th are paid on the second Wednesday, the 11th through the 20th on the third Wednesday, and the 21st through the 31st on the fourth Wednesday. People who started receiving benefits before May 1997 are generally paid on the 3rd of the month instead. Your January payment date follows that same pattern — the COLA does not change when you are paid, only how much.

The notice is the document to watch for. SSA sends a simplified, one-page COLA notice showing your exact new benefit amount and your deductions in plain language. If you have a personal my Social Security account and have enrolled in paperless notices, you can view it online starting in late November — up to three weeks before the paper notice arrives. If you do not have an account yet and want online access, SSA said you needed to create one and enroll in paperless notices by November 18, 2026. Everyone else gets the paper notice by mail in December. If December ends and you have no notice, check your my Social Security account first, then call SSA — do not assume the increase failed to apply.

The Medicare Side: What to Check Before December 7

The COLA arrives in January, but the Medicare decisions that shape your net check happen now. Medicare Open Enrollment runs from October 15 through December 7, 2026, and any change you make takes effect January 1, 2027 — the same day your new benefit starts. That overlap is not a coincidence to ignore; it is the one window each year when you can adjust the deductions that come out of your check.

Three Medicare items deserve a check before December 7:

1. The Part B premium itself. The standard premium was $202.90 a month in 2026. The Trustees project $209.50 for 2027. The official CMS number, due in November, is the one to budget from. If you pay an income-related monthly adjustment amount (IRMAA) on top of the standard premium — based on tax returns from two years earlier — your premium is higher, and the surcharge thresholds are a separate thing to verify.

2. The Part B deductible. The annual Part B deductible is also projected to rise, from $283 to $292, according to coverage of the Trustees’ figures. That is a small amount, but it affects out-of-pocket costs before Medicare starts paying its share of doctor visits and outpatient care.

3. Your Part D and Medicare Advantage plan. Premiums, formularies, and pharmacy networks change every year. A plan that was cheapest in 2026 may not be cheapest in 2027, especially if your prescriptions changed. The COLA gives you roughly $68 more a month on average; a Part D plan change can easily save or cost more than that. Review the plan, not just the premium.

If you are still working or have other coverage, the rules get more complicated — for example, if you are covered by an employer’s plan, you may be able to delay Part B without penalty. Those cases are worth a call to Medicare (1-800-MEDICARE) or your State Health Insurance Assistance Program (SHIP), which offers free local counseling. Do not guess on enrollment timing; late-enrollment penalties are permanent.

Taxes: Why a Bigger Benefit Can Mean a Bigger Tax Bill

Here is the part nobody celebrates: the income thresholds that decide how much of your Social Security benefit is taxable have never been adjusted for inflation. For single filers, up to 85% of benefits become taxable once “combined income” (adjusted gross income plus nontaxable interest plus half your Social Security benefits) passes $34,000; for joint filers, the 85% threshold is $44,000, with a lower 50% tier starting at $25,000 single and $32,000 joint. Those dollar thresholds have been fixed since the 1980s and 1990s.

What that means in practice: each COLA pushes a few more retirees over a threshold, or pushes a larger slice of their benefit into the taxable portion, even though their real purchasing power has not improved. The COLA is still worth having — you are not worse off for receiving it — but your tax bill may rise by more than you expect, and your refund may shrink. If you pay estimated tax, note the Q4 2026 estimated tax payment deadline of January 15, 2027, when any extra tax on the higher benefit comes due.

Two practical moves before December 31:

• Check your withholding. You can ask SSA to withhold federal income tax from your benefits at 7%, 10%, 12%, or 22% using Form W-4V. If your benefit rose and your other income rose too, your current withholding rate may now be too low. Adjusting it before January avoids an April surprise.
• Review Roth conversions and withdrawals. A larger benefit plus a Roth conversion in the same year can push combined income higher than planned. If you were planning a conversion, run the numbers with the new benefit amount, not last year’s.

This is general information, not tax advice — benefit taxation interacts with state rules (some states tax Social Security, most do not), IRMAA brackets, and other income in ways that deserve a professional’s eye if your situation is complex.

What the Average Figures Look Like Across Groups

The SSA’s fact sheet gives average benefits by group, and the differences are a useful reality check against the $75 headline:

A couple both receiving benefits gains about $117 a month combined on average — real money, but still less than the cost of a single month’s groceries for many households. That is the honest framing: the COLA protects purchasing power against measured inflation; it does not make anyone richer. If your costs rose faster than 3.6% — and for many retirees, health care and housing costs did — the raise still leaves a gap, and the budget work is about closing that gap from other sources.

One productive use of the increase, if your budget allows it: direct the net raise somewhere it compounds. Parking $68 a month in a high-yield savings account builds an emergency cushion of over $800 in a year, and it keeps the raise visible instead of letting it dissolve into everyday spending. That is not a recommendation for everyone — if bills are tight, the raise belongs in the budget first — but for retirees whose essentials are covered, automating the extra amount on payday is the simplest way to keep it.

Scams to Watch for This Season

Every COLA announcement brings a wave of scams, and this year is no exception. The rules are simple, and repeating them protects people:

• SSA will never call, text, or email you asking for payment to release your COLA. The increase is automatic. There is no fee, no application, and no “verification payment.”
• SSA will never threaten to suspend your benefits if you do not act immediately. Urgency is the scammer’s main tool.
• SSA will never ask for your full Social Security number, bank password, or payment by gift card or cryptocurrency. Real SSA communications direct you to ssa.gov or to call the official number.
• Be wary of “COLA calculator” sites that ask for personal information. The calculation in this article — current benefit times 1.036 — needs no account, no login, and no personal data.

If you receive a suspicious message, do not engage. You can report it to SSA’s Office of the Inspector General at oig.ssa.gov, and you can check your real benefit amount only through your my Social Security account or your official notice.

Your Pre-January Checklist

1. Calculate your own number. Current gross benefit × 1.036 = new gross benefit. Then subtract the projected Part B increase ($6.60, if it applies to you) for a net estimate — and re-run it when CMS publishes the final premium.
2. Check your notice in late November. Online if you enrolled in paperless notices by November 18; by mail in December otherwise. Confirm the new amount and every deduction line.
3. Review Medicare before December 7. Part D and Medicare Advantage changes made in Open Enrollment take effect January 1, alongside the COLA.
4. Review tax withholding. If your combined income rose, consider updating Form W-4V before January.
5. Update your budget with the net figure, not the gross one. Use the after-Medicare number for spending plans.
6. Ignore anyone charging to “claim” your COLA. It is automatic, and any such offer is a scam.

The Bottom Line

The 2027 COLA is 3.6% — about $75 a month for the average retired worker, $2,095 rising to $2,170, starting with January 2027 payments (December 31, 2026 for SSI). After a projected $6.60 Medicare Part B increase, the average net gain is about $68.40 a month, if the projection holds. Your own number depends on your benefit, your deductions, and the final Part B premium CMS publishes in November. Calculate it from your gross benefit, check your one-page notice when it arrives, use the Open Enrollment window before December 7 to review the Medicare deductions that shape your deposit, and do not let anyone charge you for an increase that is already yours by law.

Frequently Asked Questions

How much will Social Security increase in 2027?

Benefits rise 3.6% starting with January 2027 payments, the SSA announced on October 14, 2026. The average retired worker’s benefit increases by about $75 a month, from $2,095 to $2,170. Your own increase is 3.6% of your current gross benefit.

When will I see the 2027 COLA in my check?

SSI recipients see the increase on December 31, 2026. Social Security beneficiaries see it with their regular January 2027 payment, on their usual Wednesday (or the 3rd of the month for pre-May-1997 beneficiaries). The amount does not change your payment date.

How much of the raise will Medicare take?

The 2027 Part B premium is not yet final. The Medicare Trustees project an increase of $6.60 a month, from $202.90 to $209.50. If that projection holds, the average retiree keeps about $68.40 of the $75 gross increase after the standard Part B premium. CMS is expected to publish the official premium in November 2026.

Do I need to apply for the COLA?

No. The COLA is automatic for everyone receiving Social Security or SSI. You do not need to apply, pay a fee, or contact SSA. Anyone asking for payment to release your COLA is running a scam.

How is the COLA calculated?

By law, the COLA follows the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The SSA compares the average CPI-W for July through September of the current year with the same months of the previous year. For 2027, that comparison produced 3.6%.

Will the bigger benefit increase my taxes?

Possibly. The income thresholds that determine how much of your benefit is taxable ($25,000/$32,000 for the 50% tier and $34,000/$44,000 for the 85% tier, single/joint) have never been adjusted for inflation, so each COLA can make a larger slice of your benefit taxable. Consider reviewing your Form W-4V withholding before January.
