Millions of Americans receiving Social Security are preparing for the annual cost-of-living adjustment (COLA), which determines how their benefits change in response to inflation. The 2027 adjustment is expected to be announced on October 14, 2026, following the release of September inflation data. Early forecasts suggest benefits could increase by 3.5% or slightly more, although the final percentage has not yet been confirmed.
The Senior Citizens League (TSCL) estimates that Social Security benefits could rise by 3.5% in 2027, while AARP has projected an increase of 3.6%. Both estimates point to a larger adjustment than the 2.8% increase implemented for 2026. However, the official figure will depend on the inflation data used in the government’s calculation.
For retirees, the difference could affect monthly budgets, particularly for households that depend heavily on Social Security to cover essential expenses. At the same time, people who have not yet claimed retirement benefits face another important consideration: the age at which they begin collecting payments can have a substantial effect on their monthly income.
Forecast
The Senior Citizens League and AARP monitor inflation trends to estimate the annual Social Security COLA. Their projections provide an early indication of the potential increase, but neither organization determines the official adjustment.
TSCL’s latest forecast places the 2027 COLA at 3.5%, while AARP’s estimate is 3.6%. The small difference reflects the uncertainty involved in forecasting the final adjustment before all the required inflation data are available.
The 2026 COLA was 2.8%, meaning either forecast would represent a larger increase next year. Nevertheless, a higher percentage does not necessarily mean retirees will experience a comparable improvement in their purchasing power. The impact depends on how quickly the prices of food, housing, healthcare, transportation, and other necessities change.
The official determination comes from the Social Security Administration (SSA), which applies the statutory formula to the relevant inflation figures.
Beneficiaries can follow official updates through the Social Security Administration’s COLA information page.
Calculation
Social Security COLAs are based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called CPI-W. This index measures changes in the prices of goods and services purchased by a defined group of urban wage earners and clerical workers.
The SSA compares the average CPI-W for July, August, and September of the current year with the average for the same three months of the last year in which a COLA was determined. The percentage increase, rounded according to the program’s rules, establishes the adjustment.
September’s inflation report is therefore particularly important. July and August data provide an early indication of price trends, but the third-quarter average cannot be finalized until September figures become available.
The Bureau of Labor Statistics publishes the underlying data through its official Consumer Price Index page.
Inflation can change throughout the quarter, which means an early forecast may differ from the official result. The CPI-W calculation also differs from broader inflation measures frequently reported in the news.
For this reason, retirees should treat the 3.5% and 3.6% estimates as preliminary rather than confirmed benefit increases.
History
Previous COLAs illustrate how the adjustment has changed alongside inflation.
| Year | Official Social Security COLA |
|---|---|
| 2023 | 8.7% |
| 2024 | 3.2% |
| 2025 | 2.5% |
| 2026 | 2.8% |
| 2027 | 3.5% forecast by TSCL |
The 8.7% adjustment in 2023 followed a period of unusually high inflation. Subsequent increases were smaller as inflation moderated, although prices for many everyday necessities remained above their earlier levels.
If the 2027 adjustment reaches 3.5%, it would be the largest increase since 2023. That comparison, however, concerns the percentage increase in benefits, not the extent to which retirees’ individual living costs have risen.
An annual COLA is designed to help preserve purchasing power over time. It does not guarantee that every beneficiary’s expenses will rise at the same rate as the index used in the calculation.
Payments
A 3.5% COLA would increase monthly benefits according to the amount a person currently receives. The following examples show the potential effect before deductions and other adjustments.
| Current monthly benefit | Estimated monthly increase | New monthly benefit |
|---|---|---|
| $1,000 | $35 | $1,035 |
| $1,500 | $52.50 | $1,552.50 |
| $2,000 | $70 | $2,070 |
| $2,500 | $87.50 | $2,587.50 |
| $3,000 | $105 | $3,105 |
For someone receiving $2,000 per month, a 3.5% increase would mean an additional $70 each month, or $840 over 12 months.
At a 3.6% adjustment, the same benefit would rise to $2,072, an increase of $72 per month. The difference between the two forecasts would therefore be $2 per month for this beneficiary.
These examples are estimates, not guaranteed payment amounts. Actual benefits depend on the official COLA and applicable Social Security calculation and rounding rules. Medicare premiums, tax withholding, and other deductions may also affect the amount received in a bank account.
The annual adjustment is generally applied automatically to eligible benefits. Recipients do not normally need to submit a separate application to receive the COLA.
Timing
The 2027 COLA is expected to be announced on October 14, 2026, following the scheduled release of September CPI data at 8:30 a.m. Eastern time.
The adjustment will apply to benefits payable for January 2027. However, the timing of the first payment reflecting the adjustment differs by beneficiary group.
Supplemental Security Income (SSI) recipients are scheduled to receive their January 2027 payment on December 31, 2026, because January 1 is a federal holiday.
Some Social Security beneficiaries also receive payments early in the month, depending on when they began receiving benefits and whether they receive SSI. Most other retirement and disability beneficiaries follow the regular payment schedule based on their birth dates.
| Payment group | Scheduled January 2027 payment |
|---|---|
| SSI recipients | December 31, 2026 |
| Certain long-standing Social Security beneficiaries and dual recipients | December 31, 2026 |
| Beneficiaries born from the 1st through the 10th | January 13, 2027 |
| Beneficiaries born from the 11th through the 20th | January 20, 2027 |
| Beneficiaries born from the 21st through the 31st | January 27, 2027 |
Payment dates can depend on the benefit program and individual circumstances, so beneficiaries should confirm their schedules through official SSA notices.
SSI recipients may also see two payments in October 2026 because of the calendar. When a regular payment date falls on a weekend or federal holiday, the payment may be issued on the preceding business day. Such calendar adjustments do not represent additional monthly benefits.
Claiming
Although the annual COLA affects existing benefits, the age at which someone claims Social Security retirement benefits can have a much larger effect on their monthly payment.
Eligible workers can generally begin claiming retirement benefits at age 62. However, claiming before full retirement age results in a permanent reduction to the monthly benefit compared with waiting until full retirement age.
For people born in 1960 or later, full retirement age is 67. Claiming at 62 can reduce the retirement benefit by 30%, while delaying benefits beyond full retirement age can increase the payment through delayed retirement credits.
For eligible workers, delayed retirement credits generally increase benefits by 8% for each year of delay after full retirement age, up to age 70.
Consider someone entitled to $2,000 per month at a full retirement age of 67.
| Claiming age | Illustrative monthly benefit | Annual benefit |
|---|---|---|
| 62 | $1,400 | $16,800 |
| 67 | $2,000 | $24,000 |
| 70 | $2,480 | $29,760 |
This illustration excludes future COLAs and assumes the same underlying full retirement age benefit. The actual amount for an individual depends on their earnings record and claiming circumstances.
In this example, waiting until 70 rather than claiming at 62 results in $1,080 more per month, or $12,960 more annually. That is approximately 77% more monthly income than claiming at 62.
The difference is substantial because the claiming decision affects the underlying retirement benefit. Future COLAs are then applied to the benefit amount according to Social Security rules.
Longevity
Delaying retirement benefits does not guarantee a higher lifetime total for every individual. Its value depends on how long someone lives, whether they have sufficient income to cover expenses while waiting, and whether other household members depend on their benefits.
Someone who claims early receives payments for more years. Someone who delays receives larger monthly payments but collects them over a potentially shorter period.
A retiree with significant savings or other income may be better positioned to delay claiming than someone who needs Social Security immediately to pay essential bills. Health conditions, family longevity, employment, and access to other retirement resources should also be considered.
For married couples, the decision can affect survivor benefits and household income after one spouse dies. As a result, claiming strategies may have implications beyond the monthly payment received by the individual.
Delayed retirement credits stop accumulating at age 70. Waiting beyond that age does not provide additional delayed retirement credits, so eligible workers should evaluate the potential benefits of delaying against their circumstances.
Options
People who have already claimed Social Security may have limited options to change their claiming arrangements.
Under certain conditions, beneficiaries can withdraw a retirement application within 12 months of first becoming entitled to benefits. This generally requires repaying benefits received, including applicable payments made to family members based on the same earnings record and amounts withheld for taxes or Medicare. Social Security generally permits only one withdrawal of a retirement application during a person’s lifetime.
Another option is voluntary suspension. Beneficiaries who have reached full retirement age but are younger than 70 may request suspension of retirement benefits to earn delayed retirement credits.
Suspending benefits can also affect payments to certain family members, and Medicare premium payment arrangements may require attention during the suspension period. It is therefore important to understand the consequences before making a decision.
These options are not suitable for everyone. A person considering a withdrawal or suspension should review the applicable requirements and potential repayment obligations with the SSA before proceeding.
Outlook
The 2027 Social Security COLA remains unconfirmed, but current forecasts suggest an increase of around 3.5% to 3.6%. The official figure will depend on the relevant third-quarter CPI-W data released in October.
For people already receiving benefits, a higher COLA could provide additional income to help manage living costs. The actual financial benefit will depend on household spending, inflation, and any deductions from monthly payments.
For those who have not yet claimed retirement benefits, the decision about when to start collecting may have a longer-lasting effect on monthly income than the difference between the current COLA forecasts.
The most useful next step is to monitor the official announcement, review personal retirement expenses, and use confirmed benefit information when planning for 2027. A preliminary forecast can help with preparation, but the final adjustment and individual circumstances will determine what beneficiaries ultimately receive.
