Social Security beneficiaries will receive a 3.6% cost-of-living adjustment (COLA) in 2027, following an announcement from the Social Security Administration (SSA) on October 14, 2026. This is the largest annual increase in Social Security benefits since 2023.
The update affects an estimated 76 million people who receive Social Security or Supplemental Security Income (SSI). For Arizona residents reviewing retirement income and Medicare coverage, it is important to understand both the increase itself and the expenses that may affect the amount ultimately deposited each month.
Because Medicare premiums are often deducted directly from Social Security benefits, the full COLA may not always translate into the same increase in take-home income. Hamilton Advisors LLC helps clients across Arizona review Medicare costs and coverage options so they can better understand how changes like these fit into their overall budget.
What the 3.6% Social Security Increase Means
Beginning in January 2027, monthly Social Security benefits will increase by 3.6%. That is higher than the 2.8% adjustment beneficiaries received for 2026.
The SSA estimates that the average retired worker will receive about $75 more per month, with the average monthly payment rising from $2,095 to $2,170. Over a full year, that equals approximately $900 in additional Social Security income.
SSI recipients will also receive the 3.6% adjustment. Their updated benefit payments are scheduled to begin on December 31, 2026.
COLAs are intended to help beneficiaries keep pace with higher day-to-day costs. Still, the exact dollar increase depends on each person’s current benefit amount, so individual results will vary.
How the SSA Calculates the COLA
The SSA bases its annual cost-of-living adjustment on inflation. Specifically, it uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called the CPI-W.
This measure tracks changes in the cost of common goods and services, including food, transportation, and housing. The SSA compares CPI-W data from July through September with figures from the same three-month period in the prior year.
For 2027, that comparison produced a 3.6% increase. While the adjustment is meant to preserve purchasing power, it may not fully match the rising cost of healthcare or other essential expenses.
Other Social Security Updates for 2027
The COLA is not the only Social Security change taking effect in 2027. Additional updates may matter to people who are still employed, nearing retirement, or receiving retirement or survivor benefits while working.
The maximum amount of earnings subject to Social Security payroll taxes will rise from $184,500 to $192,300 in 2027.
For individuals receiving Social Security retirement or survivor benefits before full retirement age, the annual earnings limit will be $25,560 if they remain below full retirement age for the entire year. For someone who reaches full retirement age in 2027, the limit will be $67,920 for earnings received before the month they reach that age.
There is no earnings limit once a person reaches full retirement age. If you are still working at 65 or approaching retirement, it can be helpful to account for these rules when considering your income and Medicare enrollment decisions.
How Medicare Premiums Can Affect Your Net Increase
A larger Social Security payment does not necessarily mean that the entire increase will remain available for other expenses. For many people, Medicare Part B premiums are automatically withheld from their monthly Social Security benefit.
If Part B premiums rise in 2027, they may reduce part of the amount gained through the COLA. Other Medicare-related costs, including prescription drug coverage and plan premiums, can also influence a household’s healthcare spending.
This is one reason a Medicare annual review can be valuable. Reviewing your benefits, premium obligations, medications, provider access, and expected out-of-pocket costs can provide a clearer picture of what your monthly budget may look like.

Steps to Take as You Prepare for 2027
Taking a few practical steps can help you prepare for the new benefit amount and any related Medicare expenses.
- Confirm your updated benefit payment. When your notice becomes available, review your personalized COLA information through your my Social Security account. This can help you see the exact change to your monthly benefit.
- Reassess your retirement spending plan. Consider your updated Social Security income alongside Medicare premiums, taxes, housing costs, prescriptions, and other routine expenses.
- Review your Medicare coverage. A plan review can help you understand whether changes in premiums, benefits, provider networks, or prescription coverage may affect your healthcare budget.
For many beneficiaries, understanding the relationship between Social Security income and Medicare expenses is an important part of planning ahead. A careful review can help you anticipate your expected monthly income and healthcare costs with greater confidence.
