The 2027 Social Security cost-of-living adjustment (COLA) is expected to be announced in October, giving retirees a clearer picture of how much their monthly checks could increase next year.
Current private-sector estimates have placed the 2027 COLA in the mid-3% range, but the final figure will depend on inflation data from July, August and September. The important point for retirees is that the same COLA percentage does not produce the same dollar increase for everyone.
A beneficiary receiving a larger monthly payment will see a larger increase in dollars than someone receiving a smaller check. That is why states with higher typical Social Security benefits could see larger dollar increases, even though the COLA percentage is the same nationwide.
COLA Formula
Social Security’s annual COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly known as CPI-W.
The Social Security Administration compares the average CPI-W for July, August and September with the corresponding period from the previous year. The resulting calculation determines the annual adjustment.
The final 2027 COLA therefore cannot be known until the relevant inflation data are available.
The Social Security Administration explains the official COLA calculation and publishes the annual adjustments.
Benefit Amounts
Social Security benefits are not identical across the country.
A retiree’s benefit is primarily determined by factors such as lifetime covered earnings and the age at which the person claims benefits. Because earnings histories vary, average or median benefits can also differ between states.
A nationwide COLA is then applied to each eligible benefit.
For example, a 3.5% COLA would add $70 to a $2,000 monthly benefit, while the same percentage would add $52.50 to a $1,500 benefit.
The percentage is identical, but the dollar increase is different.
Top States
Based on the state-level median Social Security benefit figures cited in the source data, these 10 states have the highest median monthly benefits:
| State | Median Monthly Benefit | 3.5% Increase |
|---|---|---|
| New Jersey | $2,256 | $78.96 |
| Connecticut | $2,249 | $78.72 |
| Delaware | $2,225 | $77.88 |
| New Hampshire | $2,215 | $77.53 |
| Maryland | $2,181 | $76.34 |
| Washington | $2,144 | $75.04 |
| Michigan | $2,139 | $74.87 |
| Minnesota | $2,135 | $74.73 |
| Massachusetts | $2,121 | $74.24 |
| Utah | $2,090 | $73.15 |
These dollar amounts are illustrations using a 3.5% COLA. They are not the official 2027 increases.
The final increase for an individual retiree will depend on the person’s actual Social Security benefit and the official COLA.
Income Link
The states appearing near the top of the benefit list also include several with relatively high household incomes.
According to the Census Bureau’s 2024 American Community Survey data, six of the states listed above – New Jersey, New Hampshire, Maryland, Washington, Massachusetts and Utah – were among the states with the highest median household incomes.
Connecticut, Delaware and Minnesota also had median household incomes above the national median in the cited data.
This does not mean that higher state income automatically produces a larger Social Security check. Social Security benefits are based on an individual’s covered earnings history rather than the state in which the person lives.
The relationship is more indirect: workers who earned more during their careers can generally have higher Social Security benefits, subject to the program’s benefit formula.
2027 Estimate
The Senior Citizens League has published projections for the 2027 COLA, but projections are not official.
One recent estimate has placed the 2027 increase at around 3.5%, while other estimates can change as new inflation data arrive.
If a 3.5% adjustment were ultimately adopted, a beneficiary currently receiving $1,940.08 per month would receive an increase of about $67.90.
That would put the monthly payment at approximately $2,007.98 before considering any other changes affecting the person’s benefit.
The calculation is straightforward:
$1,940.08 x 3.5% = about $67.90
$1,940.08 + $67.90 = about $2,007.98
These figures should be treated as an illustration until the official COLA is announced.
October Announcement
The 2027 COLA is expected to be announced in October after the September CPI-W figure becomes available.
The Bureau of Labor Statistics publishes the CPI data used in the calculation, while the Social Security Administration publishes the official COLA once it has been determined.
Until then, estimates can move higher or lower depending on inflation readings.
That distinction is important for retirees planning their 2027 budgets. A forecast is an estimate, while the official COLA is the figure that determines the increase in Social Security benefits.
Dollar Increase
The phrase “biggest COLA increase” can also be confusing.
Every eligible Social Security beneficiary receives the same percentage COLA. There isn’t a separate COLA percentage for New Jersey, Connecticut or any other state.
What can differ is the dollar value of the increase because benefit amounts differ.
Suppose two retirees receive $2,250 and $1,500 per month. With a hypothetical 3.5% COLA, the first retiree would gain $78.75 per month, while the second would gain $52.50.
The difference comes from the underlying benefit, not from the retiree’s state receiving a different COLA rate.
Retirement Planning
For retirees, the 2027 COLA is only one factor in next year’s finances.
Medicare premiums, taxes, housing costs, prescription expenses and other household spending can affect how much of the Social Security increase remains available for everyday expenses.
The official COLA also does not guarantee that every retiree’s net Social Security payment will rise by exactly the same amount. Changes in Medicare premiums, withholding or other deductions can affect the amount deposited into a beneficiary’s account.
For now, the 10 states listed above have relatively high median benefit amounts in the cited data, meaning their retirees could see larger dollar increases if those benefit levels and a projected COLA are used for illustration. The actual 2027 increase will be determined nationally once the required inflation data are available.
