Social Security's 2027 cost-of-living adjustment is 3.6%, which adds about $75 a month for the average retiree, to roughly $2,170, starting in January. Medicare Part B premiums come out of most checks, and trustees project a $6.60 rise. To budget the raise, plan with the net increase, not the headline, and set aside part of it for rising costs.
Coinpurse covers budgeting and cash management for real households, and a COLA is a budgeting event for roughly 75 million people. This explainer is for retirees, near-retirees and the family members who help manage their money. It covers what was announced, how Medicare changes the math, how inflation compares and a step-by-step way to use the raise.
What Did Social Security Announce for 2027?
The Social Security Administration announced a 3.6% cost-of-living adjustment on October 14, 2026. CBS News reported that it affects more than 75 million Americans and is the biggest yearly increase in four years. The average monthly payment rises by roughly $75, to about $2,170, starting in January.
About 7.3 million Supplemental Security Income recipients see the new COLA starting December 31, 2026. The adjustment is calculated from July through September data for the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W. The 2026 adjustment was 2.8%.
The increase reflects higher inflation this year, partly from fuel prices linked to the war in Iran, according to CBS. The Consumer Price Index rose at a 3.7% annual rate in September.
How Much of the 3.6% Will You Actually Keep?
You will keep less than the headline if Medicare Part B comes out of your check. Most enrollees have the premium deducted from their monthly Social Security payment. The standard premium is $202.90 in 2026, and the official 2027 amount has not been announced.
AARP's summary of the Medicare trustees report says trustees project the 2027 standard premium to rise $6.60 to $209.50, a 3.25% increase. The Part B deductible is projected to rise from $283 to $292. The Centers for Medicare & Medicaid Services will announce the official figures later this fall.
Here is an illustration using the average benefit and the trustees' projection. It is a simplified example, not your personal number.
| Item | Monthly amount |
|---|---|
| Average COLA increase | +$75.00 |
| Projected Part B premium increase | -$6.60 |
| Net monthly raise | About $68.40 |
| Net annual raise | About $821 |
Your result will differ. If you pay an income-related surcharge, or if your Part B premium rises more than projected, your net raise will be smaller. Trustee projections have missed before, so treat $209.50 as a planning figure, not a guarantee.
Does the Hold-Harmless Rule Protect Your Check?
For many people it does. The hold-harmless provision prevents a premium increase from lowering your Social Security check below the prior year's amount. AARP says the projected 2027 increase is small enough that most beneficiaries would be partly shielded by it.
About 30% of Part B enrollees are not eligible, according to AARP. They include people who do not receive Social Security checks and those subject to income-related adjustments. If you fall into one of those groups, plan for the full premium increase.
A one-time $90 payment will go to 20.8 million original Medicare beneficiaries to help with Part B premiums, according to the same summary. Medicare Advantage enrollees are not eligible. That payment covers less than half of one month's premium, so it is welcome but small.
Does 3.6% Keep Up With Prices?
Roughly, but not for everyone. CBS notes that the Consumer Price Index rose 3.7% in September, so the COLA is about even with current inflation. Critics point out that the 2026 adjustment of 2.8% lagged inflation for seven months.
The Senior Citizens League's Shannon Benton said COLAs are designed to keep pace with inflation, not make up for years of falling behind. A financial planner quoted by CBS said healthcare inflation runs 5.8% a year while COLAs average 2.4%. An AARP survey found about three-quarters of older Americans think the adjustment will not keep up with prices.
The reason is that the index measures a broad basket. Retirees spend more on healthcare and housing than the average worker, and those costs can rise faster. Your own inflation rate depends on what you buy.
Step by Step: How to Budget the 2027 Raise
Use this sequence in November and December, before the first larger check arrives:
- Wait for your official benefit notice, which shows the new gross amount and the Part B deduction.
- Subtract the new Part B premium and any other deductions to find your true net raise.
- List your biggest expenses and note which ones are rising fastest.
- Assign the first slice of the raise to the costs that have already increased.
- Put a set amount into a buffer for medical costs and home repairs.
- Choose one small improvement, such as extra savings or a planned treat, for what remains.
Step one matters because you should not spend a raise you have not seen. The notice, usually mailed or posted to your online account in December, is the number to build on.
If you track spending by category, a method like zero-based budgeting makes it easy to give every dollar a job. Our guide to zero-based budgeting step by step shows how to set it up, and it works as well on a fixed income as on a paycheck.
Where Should the Extra Money Go?
Pay for the known increases first, then build safety. Groceries, utilities, insurance and medical costs usually rise before anything else. Cover those, and the raise has done its job.
A small buffer is the next priority. A fixed income leaves little room for surprises, so a cushion of even a few hundred dollars helps. Our guide to sinking funds explains how to set aside money for predictable but irregular costs such as dental work, car repairs and gifts.
Think about where the cushion lives. Cash in a savings account that earns very little loses ground to inflation. Our recent piece on what the Fed's rate hike means for savings accounts and CDs shows how large the gap between average and top rates has become.
How to Avoid the Costs That Eat a COLA
Review recurring bills once a year. Phone, internet, insurance and subscriptions often creep up. A one-hour review can recover more than the COLA adds. Ask for loyalty or senior discounts where available.
Watch debt carefully. If you carry a card balance, the interest can erase a raise quickly. The Federal Reserve's latest data shows an average card rate above 22% on accounts that carry a balance. Paying down a balance is often the best use of extra money.
The holiday season tests every budget. If a larger check starts in January, do not spend it in advance on gifts. Our guide to building a holiday budget that avoids January debt shows how to plan seasonal costs from cash on hand.
What If the Raise Is Not Enough?
If costs outrun the raise, look at the biggest categories first. Housing, healthcare and transportation are where changes matter most. Compare Medicare plans during open enrollment, review drug coverage and check whether you qualify for programs that help with premiums or prescriptions.
Local benefit counselors can review your options for free. Agencies on aging and state health insurance assistance programs help people compare plans and find savings. A certified financial planner can also help you set a sustainable withdrawal plan if you rely on savings.
Who Should Talk to a Professional?
Anyone with a mix of income sources should get personal advice. If you owe tax on benefits, hold investments or plan to claim Social Security soon, a COLA changes more than your monthly check. A fee-only planner or a tax professional can model the effect on your tax bracket and Medicare surcharges before you make a move.
What Could Change Before January?
The official Part B premium is the main unknown. If CMS sets it above the trustees' projection, your net raise shrinks. Taxes can also change your take-home benefits if you owe tax on part of your Social Security.
The longer-term picture also matters. Trustees project COLAs averaging 2.4% a year from 2027 to 2031, while premiums rise faster, according to AARP. Plan for a slow squeeze rather than assuming each raise will feel as large as this one.
Conclusion
The 3.6% COLA is the largest in four years, but the real raise depends on Medicare, taxes and what you spend on. Wait for your benefit notice, calculate your net increase, cover known cost increases and build a small buffer. A steady plan helps the raise last.
This is general information, not personalized financial or tax advice. This week, review your recurring bills and make a list of the costs that went up this year. Coinpurse will track the official Part B announcement and update what it means for your budget.
