Quick Read
July CPI-W data releases Aug. 12 and offers the first clue for the 2027 COLA, but August and September readings also shape the final number.
The 2026 Medicare Part B premium rose $17.90 per month, directly offsetting much of the 2.8% COLA retirees received.
COLAs are designed only to preserve purchasing power against inflation, not improve retirees’ finances, making personal savings and supplemental income essential.
Two retirees, same $1 million, same 4% rule, buy one finished with $1.4 million, the other hit $0 in 12 years. Our free reader guide explains the flaw that separated them, and the income-first method built to avoid it.
For millions of older Americans, Social Security’s annual cost-of-living adjustment (COLA) is one of the most closely watched financial updates of the year. That increase is designed to help benefits keep pace with inflation, giving retirees a better chance of maintaining their purchasing power as prices rise for groceries, housing, health care, and other essentials.

But this year’s 2.8% COLA left many retirees disappointed. While the increase provided some additional income, many seniors felt it did not fully reflect the financial pressures they continue to face.
Plus, in 2026, the cost of Medicare rose substantially. The standard monthly Part B premium increased by $17.90, which came right out of that 2.8% raise for enrollees in both Medicare and Social Security.
Now, attention is turning toward the 2027 COLA. And one important piece of information should be arriving soon.
July inflation should offer an early look at the 2027 COLA
Social Security COLAs are based on third quarter data from the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. That three-month average from July, August, and September is compared with the same period from the previous year, and the percentage increase determines the following year’s COLA.
The 4% Rule is Broken, Built On A World That No Longer Exists
Every retiree knows about the 4% rule, but it frames retirement as a slow liquidation and still causes retirees with seven-figure accounts to agonize over a dinner out.
There’s a different way to run the math that makes more sense today. Build an income floor — dividends, interest, and Social Security that cover your essential bills every month — and you never have to sell shares into a down market just to pay them.

The first major clue for the 2027 COLA will arrive when July CPI-W data is released on Aug. 12 (assuming it comes out on time). That number will give retirees and analysts an early indication of whether inflation is trending higher or lower and what kind of COLA might be possible in the new year.
However, July is only one-third of the calculation. The final COLA number depends on all three months of third-quarter inflation data. August and September CPI-W readings will need to be accounted for before the Social Security Administration is able to make an official COLA announcement in October.
That means retirees should avoid putting too much weight on a single inflation report. A hotter-than-expected July reading could point toward a larger COLA. But cooler inflation in August or September could change the final outcome.
It’s important to keep expectations in check
You may be hoping for a generous Social Security COLA in 2027. But it’s important to understand what COLAs are and are not meant to do.
COLAs are meant to preserve purchasing power to the extent that inflation rises. But they’re not designed to improve your financial situation. If you’re already struggling to cover your monthly expenses, a generous COLA probably isn’t going to solve that problem.
A better solution? Try to find ways to reduce spending or generate additional income. You may find that working part-time provides extra financial flexibility.
Just be mindful of Social Security’s earnings test, which applies to people who claim benefits prior to full retirement age. Under the earnings test, you may have benefits withheld temporarily if your income exceeds a certain threshold that changes each year.
If you’re not yet retired, it’s also important to realize that Social Security was never meant to be your only source of retirement income. Knowing that, plus the limited scope of COLAs, might motivate you to save more for your post-working years.
Before Your Next Withdrawal, Run One Number ( It’s Not The 4% Rule Everyone Knows)
Take your essential monthly expenses and subtract your guaranteed income — Social Security, plus any pension. What’s left is your income gap, and how you close it determines whether retirement runs on share sales or on a paycheck your portfolio writes you every month. Our free reader guide, The 4% Rule Is Broken, shows exactly how to close that gap with portfolio income: a worked example (one retiree needed about $480,000 in income-producing assets to cover his essentials for good), an eight-point conversion checklist, and the 20-year numbers comparing dividends to withdrawals. It’s free and takes about 15 minutes to read. Get the guide here before you take your next withdrawal.
