The 2027 Social Security Cost-of-Living Adjustment has not yet been officially announced. The Social Security Administration has confirmed that the next COLA will be announced in October 2026, with the expected announcement date of October 14, 2026.
The final 2027 COLA percentage cannot be determined until the Bureau of Labor Statistics releases the September 2026 Consumer Price Index data, which is scheduled for October 14. That data will complete the final piece needed for the official COLA calculation.
Currently, independent forecasts place the 2027 COLA in the range of 3.2% to 3.6%. The Senior Citizens League projects 3.6% for 2027, while other analysts estimate 3.4% to 3.5%. A 3.6% COLA would be larger than the 2.8% increase beneficiaries received for 2026.
The 2027 COLA would take effect with benefits payable in January 2027.

The annual Cost-of-Living Adjustment (COLA) is designed to help Social Security and Supplemental Security Income (SSI) benefits keep pace with inflation. The adjustment is intended to protect the purchasing power of benefits as prices for goods and services rise over time.
The COLA is tied to changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a measure of inflation produced by the Bureau of Labor Statistics. Under current law, the Social Security Administration uses the CPI-W to calculate the annual adjustment.
When the CPI-W rises from the third quarter of one year to the third quarter of the next, the percentage increase becomes the COLA for the following year.
The Social Security Administration has confirmed that the next COLA will be announced in October 2026.
The expected announcement date is October 14, 2026. This is the date when the Bureau of Labor Statistics is scheduled to release the September 2026 Consumer Price Index data — the final piece of information needed to complete the official COLA calculation.
The final percentage cannot be determined before October because the calculation requires inflation data from July, August, and September of 2026.
| Month | Event |
|---|---|
| July 2026 | CPI-W data released |
| August 2026 | CPI-W data released |
| September 2026 | CPI-W data released (October 14) |
| October 2026 | Official 2027 COLA announced |
| January 2027 | Higher benefits begin |
The Social Security COLA calculation follows a straightforward statutory formula:
The formula does not use a single month’s inflation rate. Some beneficiaries may see July’s annual inflation rate reported at 3.4% and assume a 3.4% COLA, but that is not how the calculation works. The final COLA depends on the three-month average, so August and September data can still pull the final number higher or lower.
The Social Security COLA for 2026 was 2.8%, announced by the Social Security Administration on October 24, 2025.
This adjustment affected nearly 71 million Social Security and SSI beneficiaries. The average retired worker’s benefit increased by approximately $56 per month. The 2026 COLA represented a modest increase compared to the 8.7% COLA in 2022, but was higher than the 2.5% COLAs for 2024 and 2025.
| Year | Social Security COLA |
|---|---|
| 2021 | 5.9% |
| 2022 | 8.7% |
| 2023 | 3.2% |
| 2024 | 2.5% |
| 2025 | 2.5% |
| 2026 | 2.8% |
| 2027 | Pending |

There is no official 2027 COLA percentage yet. The official figure will be announced on October 14, 2026, after the September 2026 CPI data is released.
However, independent analysts and organizations have provided estimates based on current inflation trends:
| Organization/Individual | 2027 COLA Estimate |
|---|---|
| The Senior Citizens League | 3.6% |
| AARP | ~3.5% |
| Independent Analyst Mary Johnson | 3.4% |
| Estimate Range | 3.2% – 3.6% |
It is important to note that these are estimates and projections, not official announcements. The final percentage depends on the CPI-W data from July, August, and September 2026, and could change as more data becomes available.
Based on the average retired worker’s benefit and the current COLA estimate range, here is what a 3.6% increase could mean in practical terms:
| Current Monthly Benefit | COLA Increase (3.6%) | New Monthly Benefit |
|---|---|---|
| $1,500 | +$54 | $1,554 |
| $1,800 | +$65 | $1,865 |
| $2,000 | +$72 | $2,072 |
| $2,083 (average retiree benefit) | +$75 | $2,158 |
| $2,500 | +$90 | $2,590 |
| $3,000 | +$108 | $3,108 |
Note: These are hypothetical illustrations based on the current 3.6% estimate. The actual 2027 COLA may differ. A small difference between forecasts may appear unimportant, but two-tenths of a percentage point on a $2,000 benefit is $4 a month, or $48 over a year.
The 2027 COLA will take effect with benefits payable in January 2027.
It is important to understand the difference between the effective month and the payment schedule. The COLA applies to benefits beginning with the December 2026 benefit, which is actually paid in January 2027.
Recipients will see the higher payment in their January 2027 benefit check (or direct deposit). The Social Security Administration will provide official payment schedules after the COLA is announced in October.
The COLA adjustment generally applies to eligible recipients of:
The exact dollar increase depends on the individual’s benefit amount. Not every person receives the same dollar increase, as the percentage is applied to each beneficiary’s specific monthly payment.
Supplemental Security Income recipients generally receive the same COLA adjustment as Social Security beneficiaries. Federal SSI payment standards are adjusted annually based on the COLA.
For 2026, the federal SSI payment standard increased due to the 2.8% COLA. The 2027 adjustment will be determined by the official COLA announced in October 2026.
It is important to note that individual SSI payment amounts may differ based on state supplemental benefits, living arrangements, and other income.
A higher Social Security benefit does not necessarily mean beneficiaries will see the entire gross COLA increase in their bank account. Several factors can reduce the net increase:
The standard monthly Medicare Part B premium is a significant factor. In 2026, the standard premium rose to $202.90, an increase of approximately 10% from 2025. The 2026 Medicare Trustees Report projects the standard 2027 premium at approximately $209.50, an increase of $6.60 per month.
This means a projected $75 monthly COLA gain could be reduced to roughly $68 before beneficiaries see any increase. Private analysts expect the actual 2027 premium could fall between $215 and $219 based on recent patterns.
A hold-harmless provision prevents most beneficiaries’ Medicare Part B premium increases from exceeding their Social Security COLA in dollar terms. However, this provision cannot stop the premium from consuming a portion of the COLA gain.
Up to 85% of Social Security benefits can be taxable depending on income. The thresholds for taxation — $25,000 for single filers and $32,000 for joint filers — have not been adjusted for inflation since the 1980s. A larger COLA can push more retirees over these thresholds and into taxes on benefits they already earned.
The COLA is designed to help Social Security benefits keep pace with inflation. Inflation affects beneficiaries’ purchasing power through everyday expenses such as:
However, the COLA may not perfectly match every beneficiary’s personal expenses because individual spending patterns differ. The CPI-W, which measures inflation for urban wage earners and clerical workers, may not precisely reflect the spending patterns of retirees, who often spend more on healthcare.
CPI-W stands for Consumer Price Index for Urban Wage Earners and Clerical Workers. It is produced by the Bureau of Labor Statistics and measures the average change over time in prices paid by urban wage earners and clerical workers for a market basket of consumer goods and services.
According to the Social Security Administration, this is the index used under current law to calculate the annual COLA.
The CPI-W is different from the more commonly cited CPI-U (Consumer Price Index for All Urban Consumers). The CPI-W covers a smaller population group — approximately 29% of the U.S. population compared with about 93% for CPI-U.
Below is a historical table of Social Security COLAs over recent years:
| Year | COLA |
|---|---|
| 2018 | 2.8% |
| 2019 | 1.6% |
| 2020 | 1.3% |
| 2021 | 5.9% |
| 2022 | 8.7% |
| 2023 | 3.2% |
| 2024 | 2.5% |
| 2025 | 2.5% |
| 2026 | 2.8% |

The timeline before the official COLA announcement includes:
The 2027 COLA can differ from the 2026 figure because it depends entirely on inflation measured during the third quarter of 2026 under the statutory formula. If inflation is higher in 2026 than it was in 2025, the COLA will be higher. If inflation is lower, the COLA will be lower.
Currently, estimates suggest the 2027 COLA will be higher than the 2.8% COLA for 2026. The current forecast range of 3.2% to 3.6% would make 2027 the largest COLA since 2022’s 8.7% adjustment.
It is also worth noting that a high COLA is often both good and bad news. A larger COLA means higher benefits, but it also reflects higher inflation. The purpose of the COLA is to maintain purchasing power, not to provide additional income. As one analyst noted, a high COLA can mean higher inflation, which historically has eroded Social Security purchasing power over time.

The Social Security Cost-of-Living Adjustment (COLA) is an annual increase to benefits designed to help Social Security and Supplemental Security Income recipients keep up with inflation.
The 2027 COLA is expected to be announced on October 14, 2026, after the September 2026 CPI data is released.
The 2027 COLA has not been officially announced yet. Current estimates range from 3.2% to 3.6%, but the official figure will be announced in October.
The Social Security COLA for 2026 was 2.8%.
The COLA is calculated by comparing the average CPI-W (Consumer Price Index for Urban Wage Earners and Clerical Workers) from the third quarter of the current year with the average from the same three months of the previous year.
Yes, Supplemental Security Income recipients generally receive the same COLA adjustment as Social Security beneficiaries.
The 2027 COLA will take effect with benefits payable in January 2027.
Yes, Medicare Part B premiums are automatically deducted from Social Security payments and can consume a portion of the COLA increase.
No. The COLA is a percentage applied to each individual’s benefit amount, so the dollar increase varies.
