Social Security announced a 3.6 percent cost of living adjustment (COLA) for 2027. Good news, right? Mostly. If you have ever opened your January statement and wondered why your deposit did not rise as much as the headline suggested, this article is for you.
The COLA affects your benefit. Medicare premiums can affect what reaches your bank account. And taxes can affect how much you ultimately keep.
What Is the 2027 Social Security COLA?
On October 14, 2026, the Social Security Administration announced a 3.6 percent COLA for 2027. It applies to nearly 72 million Social Security beneficiaries and begins with benefits payable in January 2027. It is the largest increase since 2023.
The COLA is set by comparing consumer prices in the third quarter of this year to the same quarter a year ago. In plain English, it is a catch up for price increases that already happened, not a bonus for the year ahead.
| Year | COLA |
|---|---|
| 2023 | 8.7% |
| 2024 | 3.2% |
| 2025 | 2.5% |
| 2026 | 2.8% |
| 2027 | 3.6% |

What Does a 3.6 Percent COLA Mean in Dollars?
For the average retired worker, the SSA estimates the 2027 Social Security payment increase at about $75 a month. For a couple in which both spouses receive benefits, the estimated average increase is about $117 a month. Those are before Medicare premiums and taxes.
| Average monthly benefit | 2026 | 2027 |
|---|---|---|
| Retired worker | $2,095 | $2,170 |
| Couple, both receiving benefits | $3,238 | $3,355 |

Will Medicare Reduce Your Increase?
Possibly. Medicare Part B premiums are often deducted directly from your Social Security check. The Medicare Trustees project the standard Medicare Part B premium for 2027 at $209.50 a month, compared with $202.90 in 2026. That is a projection, not the final CMS announcement, which is expected later this fall. Higher income can also trigger a Medicare surcharge called IRMAA, short for income-related monthly adjustment amount, and Medicare looks back two years at your income to set it.
Here is what that can look like for someone receiving $2,000 a month. A 3.6 percent COLA adds $72 a month. If the projected $6.60 Part B increase holds, that leaves about $65 more per month before taxes or other adjustments.
Hypothetical illustration for discussion purposes only. Individual circumstances and results will vary.
Can Taxes Shrink the Raise?
Yes. For federal income tax, Social Security benefits can begin to be taxable once your combined income (your adjusted gross income, plus nontaxable interest, plus half of your Social Security benefits) passes $25,000 for a single filer or $32,000 for a married couple filing jointly. Above roughly $34,000 for a single filer or $44,000 for joint filers, up to 85 percent of your benefit can be included in taxable income. That does not mean your benefits are taxed at an 85 percent rate. It means up to 85 percent of the benefit is counted as income, and then taxed at your normal rate.
Those thresholds have never been adjusted for inflation, so every COLA nudges a little more of your benefit toward the taxable zone.
Where you live matters too. California does not tax Social Security benefits. Colorado offers subtractions for qualifying retirement income, including Social Security, with details depending on your age and income. We walk through them in our article, How Colorado Taxes Retirement Income.
When Will You Know Your Exact Benefit?
Your 2027 Social Security benefit amount will show up in your my Social Security account starting in late November, and you need an account by November 18 to see it online. If you are not signed up for online notices, a letter arrives by mail in December. Read that notice for your actual benefit and Medicare deduction instead of relying on the headline percentage.
How the COLA Fits Into Spend, Grow, Secure
In the Redwood Retirement Framework, every dollar has a job. The COLA is no different.
Spend. If groceries, healthcare, insurance and other costs are taking more of your income, the increase can help cover them. Spend is the cash for the next three to five years of living costs, and the COLA helps that bucket keep pace.
Grow. If you do not need the extra cash flow, it may reduce what you have to withdraw from your longer term investments, leaving more of that money invested.
Secure. Secure is the money you do not plan to spend, the assets you want to leave behind, such as a Roth IRA or real estate. A raise you do not need can be pointed there.
The question is not simply, “Did I get a 3.6 percent raise?” It is, “What job should this additional income perform in my retirement plan?”
What If You Have Not Claimed Social Security?
You generally do not have to claim benefits for COLAs to count. They are added to your benefit calculation starting the year you turn 62, so waiting does not mean missing them. For some people, the years between retirement and claiming can also be a window to look at Roth conversions and withdrawal sequencing. See our article, Roth Conversions Before Social Security: When Do They Make Sense?
Do Not Build a Retirement Plan Around One Number
A 3.6 percent COLA is welcome, but it is one adjustment in one year. When to claim, how much to withdraw, which accounts to tap, how taxes and Medicare interact, and how much to preserve for the future all matter more.
A bigger Social Security check is helpful. A retirement plan that gives every dollar the right job is better. If you would like to see how the 2027 Social Security COLA fits your own numbers, we would be glad to take a look.
