Although the projected Social Security cost-of-living adjustment (COLA) for 2026 is estimated at 2.7%, this increase will not be fully reflected in the pockets of many beneficiaries. While this sounds like good news on paper, the financial reality for retirees tells a different story.

Based on average payments reported in August 2025, which were approximately $2,008 per month per retired worker, the 2.7% adjustment would imply a gross increase of approximately $54 per month. However, this figure does not account for deductions or increases in other expenses related to Social Security benefits.

One of the main reasons this increase will not be complete is the rising cost of Medicare Part B, the premium for which is deducted directly from Social Security checks.

In 2025, the standard Part B premium increased from $174.70 to $185.00. According to projections by the Medicare Trustees, this premium could reach $206.50 by 2026.

If that increase goes through, the net benefit for the average retiree would fall to just $32.50 more per month. That means nearly 40% of the projected increase would be absorbed by the Medicare premium alone.

Added to this are other expenses that are often subtracted from payments, such as supplemental health plans, state taxes, or automatic deductions for other insurance. All of this further reduces the effective benefit a retiree will receive in their bank account.

Although COLAs are designed to offset inflation, they don't cover all real cost-of-living increases. They only track average prices, not taking into account items like health care, which tend to increase more rapidly.

Furthermore, the official COLA figure is still unconfirmed. The Social Security Administration will announce the final percentage, which was scheduled for October 15. However, Due to the government shutdown and the Bureau of Labor Statistics' (BLS) delay in releasing the Consumer Price Index (CPI), better known as the inflation report, the Social Security COLA will be announced on October 24.

It's critical to understand that relying solely on the COLA doesn't guarantee financial stability in retirement. As the data shows, even a healthy increase can be offset by other economic factors.

That's why experts advise diversifying income sources. Exploring yield-producing investments, such as stocks, bonds, or dividend funds, can provide further financial support. Part-time work or gig work that fits the retiree's lifestyle can also be considered.

Expecting more than the Social Security COLA without preparing for hidden costs is a risky bet. Starting to build supplemental income today is key to a more solid retirement that's less vulnerable to the inevitable rise in healthcare costs.
