The Social Security Administration is scheduled to announce the 2027 cost-of-living adjustment (COLA) on October 14 at 8:30 a.m. ET. The announcement will give millions of Social Security beneficiaries the official percentage increase that will apply to benefits beginning in January 2027.
Current estimates put the 2027 COLA near 3.5% to 3.6%, although the final figure will depend on inflation data that has not yet been fully incorporated into the calculation. Until the SSA releases the official number, projections remain subject to change.
Date
The SSA is expected to announce the 2027 COLA on October 14, 2026. The agency needs the September inflation figures before completing the annual calculation.
The timing gives beneficiaries several weeks to prepare for the new payment amounts. Once the official percentage is announced, retirees and other recipients can use it to update their household budgets and retirement income plans for 2027.
Formula
The Social Security COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called CPI-W.
The calculation compares the average CPI-W for July, August, and September of the current year with the average for those same three months in the previous year. The resulting difference determines the annual adjustment.
In simple terms, the formula measures how consumer prices changed during the third quarter. If prices rise, Social Security benefits generally receive a corresponding adjustment under the statutory formula.
Forecasts
Current projections indicate that the 2027 COLA could be around 3.5% to 3.6%. The Senior Citizens League has estimated a figure near 3.6%, while AARP has projected approximately 3.5%.
These forecasts are not the final COLA. The remaining inflation data can influence the calculation, which means estimates may change before the October announcement.
If the final COLA is 3.6%, an average monthly Social Security benefit of approximately $2,071 would increase by about $75 per month. That would bring the average payment to roughly $2,146.
| Potential COLA | Approx. Monthly Increase | Approx. New Benefit |
|---|---|---|
| 3.5% | $72 | $2,143 |
| 3.6% | $75 | $2,146 |
The actual increase will depend on each beneficiary’s individual monthly benefit.
History
A 3.6% COLA would be higher than the 2.8% adjustment that took effect in January 2026. The 2026 increase raised the average monthly benefit by approximately $56.
Social Security adjustments have varied considerably in recent years. Beneficiaries received an 8.7% COLA in 2023, followed by 3.2% in 2024 and 2.5% in 2025.
The unusually large 2023 increase reflected elevated inflation during the period following the pandemic. The smaller adjustments in later years reflected more moderate changes in consumer prices.
A potential 3.6% increase in 2027 would therefore represent a larger adjustment than those seen in 2024, 2025, and 2026, although it would remain well below the 2023 increase.
Impact
For Social Security recipients, the COLA can affect monthly income throughout the year. A 3.6% increase on an average benefit of about $2,071 would amount to approximately $75 more per month, or about $900 over 12 months before accounting for taxes or other deductions.
However, the increase does not necessarily translate into the same improvement in purchasing power. The effect depends on how prices for housing, food, healthcare, utilities, and other expenses change during 2027.
This distinction is important when preparing a retirement budget. A higher Social Security payment can provide additional income, but beneficiaries still need to consider their overall expenses and other sources of retirement income.
Planning
The October 14 announcement will give retirees and financial planners a firm figure to use when preparing 2027 budgets. Until then, current projections can provide a general estimate but should not be treated as the final payment increase.
Beneficiaries should also remember that the COLA is not the only factor that can affect the amount they receive. Medicare premiums, federal income taxes, voluntary withholding, and other deductions may influence the net amount deposited into a bank account.
The official 2027 COLA will replace the forecasts that have circulated throughout the year once the SSA releases the final calculation. For now, the key dates are the remaining inflation reports and the expected October 14 announcement. The final percentage will determine how Social Security benefits change beginning in January 2027.
