Social Security’s cost-of-living adjustment for 2027 is 3.6 percent, the Social Security Administration (SSA) announced October 14, and it reaches about 76 million Americans who receive Social Security or Supplemental Security Income (SSI). The raise does not land on a single date. SSI payments rise starting December 31, 2026, while Social Security benefits rise starting with January 2027. This year’s adjustment was 2.8 percent, so the new figure is a step up, though the Bureau of Labor Statistics reported the same morning that its wage-earner price index was up 3.9 percent over the past 12 months.
For beneficiaries, the first questions are when the new amount shows up and how SSA will tell them. The agency says nearly 72 million people receive Social Security and about 7.3 million receive SSI, and it puts the average retirement increase at about $75 a month starting in January. Personal notices are due in the Message Center of online accounts in late November. Anyone who does not use online notices gets a paper letter in December.
The raise reaches SSI recipients on December 31 and Social Security beneficiaries in January, so the first raised deposit arrives on two different dates. The Social Security Check Protection Kit puts the 2026 payment calendar in one place and adds a first-24-hours plan for a late or missing payment.

Two tracks: SSI on December 31, Social Security in January
SSA’s COLA page says increased payments to about 7.3 million SSI recipients begin December 31, 2026. SSI is the program for people with limited income and resources, and its federal rate is a set dollar amount rather than a share of an earned benefit. In SSA’s table of SSI amounts, the federal rate rises to $1,029 a month for an individual and $1,544 for a couple, up from $994 and $1,491 this year. That is $35 more for an individual and $53 more for a couple.
Social Security beneficiaries wait a little longer. The adjustment starts with benefits payable in January 2027, and the agency says nearly 72 million people receive the 3.6 percent. SSA’s announcement post gives about $75 a month as the average retirement increase, but that number is an average. The percentage is applied to what each person already receives, so a larger check gains more than $75 and a smaller check gains less.
How the 3.6 percent was figured
The adjustment follows the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W, which the Bureau of Labor Statistics produces. SSA says the COLA is the percentage increase in that index from the third quarter of the last year a COLA was set to the third quarter of the current year. If the index shows no increase, there is no COLA. Only the July, August and September readings count, which made the September report the last piece of the calculation.
That report came out the same morning as SSA’s announcement. The Bureau of Labor Statistics put the September CPI-W at 330.654, up 3.9 percent from a year earlier. The 3.6 percent COLA is lower than that 12-month rise because it averages the three months of the third quarter and compares them with the same three months a year ago, rather than looking at September alone. A September reading that runs above the quarter’s average, as this one does, shows prices still rising at the end of the measuring period.
The same BLS report shows where prices moved. Energy was up 20.4 percent over 12 months and 5.2 percent in September alone, while shelter rose 3.2 percent over the year and food rose 2.5 percent. Grocery prices fell 0.1 percent in September. A 3.6 percent raise therefore covers some household budgets more comfortably than others, depending on how much of the budget goes to fuel and utilities rather than food at home.
The notice, the account deadline and the tax cap
Nick Perrine, SSA’s chief communications officer, signed the agency’s October 14 letter to advocacy groups. It asks them to tell members that people with a my Social Security account can see their personal COLA online up to three weeks before it arrives by mail. The letter says beneficiaries must sign up for digital notices by November 18, 2026, and the COLA page says online notices go to accounts created by that date. Account holders can also opt into text or email alerts when a new Message Center message appears.
The same announcement raises the maximum earnings subject to Social Security payroll tax to $192,300 in 2027 from $184,500. That is $7,800 more in wages taxed for the highest earners, and it takes effect in January along with the benefit increase. The tax cap does not change what any retiree receives, but it is the other half of the January adjustments SSA announced on the same day.
Watching for the first raised deposit
Beneficiaries who want the notice as early as possible can create or sign in to an account at my Social Security. SSA says the account also lets people change an address or direct deposit and print proof of benefits. Because notices reach online accounts first, an account opened before November 18 is the quickest route to the exact new amount.
SSI recipients should look for the first payment at the higher rate on December 31, 2026, the date SSA lists, rather than waiting for a January deposit. Social Security beneficiaries should look to their January 2027 benefit. Anyone whose raised deposit is missing or short on those dates has a specific day to point to when calling the agency.
SSA has not published a single dollar figure that applies to everyone. Its notice, due online in late November and by mail in December, is the document that fixes each person’s new amount, and the $75 average is only an average.
Two deposit dates, one raise, no room for a late payment
One detail separates the two programs: SSI’s raise starts December 31 and Social Security’s in January. The Social Security Check Protection Kit sets out the 2026 payment calendar and a first-24-hours plan for a late or missing payment, so a raised deposit that fails to arrive gets handled the same day it is missed.
