Quick Answer: The Social Security COLA 2027 is projected to land between 3.2% and 3.6%, with most forecasts clustered around 3.5%. AARP projects 3.6%, The Senior Citizens League projects 3.5%, and the fiscal group CRFB projects 3.2%. That would be higher than the 2.8% COLA for 2026 and the biggest raise since 2023. A 3.6% increase would add about $75 a month to the average retired worker’s check. The official 2027 COLA is expected to be announced on October 14, 2026, and it takes effect with January 2027 payments.
The Social Security COLA 2027 is shaping up to be one of the bigger raises retirees have seen in years. After a 2.8% bump in 2026, new inflation data points to an increase in the mid-3% range for 2027.
For the roughly 75 million Americans who receive Social Security or Supplemental Security Income (SSI), that could mean a meaningful boost to monthly income. But the final number is not official yet, and rising Medicare costs could take a bite out of the raise.
This guide explains the latest COLA forecasts, how much your check could rise, when the official number will be announced, when you will see the money, and what else could change in 2027.
What Is the Social Security COLA?
COLA stands for cost-of-living adjustment. It is an annual increase to Social Security and SSI benefits that helps payments keep up with inflation. Social Security payments have been adjusted automatically for inflation every year since 1975.
Without a COLA, rising prices would slowly erode the buying power of a fixed monthly check. The COLA is designed to help retirees, people with disabilities, and other beneficiaries afford roughly the same goods and services year after year.
Social Security COLA 2027 Estimates
Several groups have published forecasts based on inflation data through August 2026. Here is where they stand:
| Forecaster | 2027 COLA Estimate |
|---|---|
| AARP | 3.6% |
| The Senior Citizens League (TSCL) | 3.5% |
| Mary Johnson, independent Social Security analyst | About 3.4%–3.5% |
| Committee for a Responsible Federal Budget (CRFB) | 3.2% |
AARP’s policy experts have said that unless prices change dramatically in September, they expect the COLA to land in the mid-3% range. The Senior Citizens League trimmed its estimate to 3.5% from 3.6% after the August inflation report.
Estimates have swung a lot this year. Earlier in 2026, when inflation surged, some forecasts briefly climbed above 4%. As inflation cooled over the summer, projections came back down to the mid-3% range.
How Is the COLA Calculated?
The COLA formula is set by law. It uses a specific inflation measure called the CPI-W, the Consumer Price Index for Urban Wage Earners and Clerical Workers, published monthly by the Bureau of Labor Statistics.
Here is how it works:
- Take the average CPI-W for July, August, and September of the current year.
- Compare it with the average for the same three months of the previous year.
- The percentage increase becomes the next year’s COLA.
Two of the three months are already in. On September 11, the BLS reported that the CPI-W rose 3.5% in August compared with a year earlier. The last piece, September’s CPI-W, is scheduled for release on October 14, 2026. For a deeper look at the latest inflation numbers, see our breakdown of the August 2026 CPI report.
Why the CPI-W Matters
Critics point out that the CPI-W tracks the spending of working-age households, not retirees. Older Americans usually spend more of their budgets on healthcare and housing. That is why some advocates push for using a senior-focused index, often called the CPI-E, instead. For now, the law still uses the CPI-W.
How Much Will Your Social Security Check Increase?
AARP estimates that a 3.6% COLA would raise the average retired worker’s benefit by about $75 a month. The average retired worker received about $2,071 a month as of January 2026, according to Social Security Administration data.
Here is how different COLA outcomes could affect monthly benefits:
| Current Monthly Benefit | At 3.2% COLA | At 3.5% COLA | At 3.6% COLA |
|---|---|---|---|
| $1,000 | +$32.00 | +$35.00 | +$36.00 |
| $1,500 | +$48.00 | +$52.50 | +$54.00 |
| $2,000 | +$64.00 | +$70.00 | +$72.00 |
| $2,071 (average retiree) | +$66.27 | +$72.49 | +$74.56 |
| $2,500 | +$80.00 | +$87.50 | +$90.00 |
| $3,000 | +$96.00 | +$105.00 | +$108.00 |
These are simple estimates before Medicare premiums and any other deductions. The Social Security Administration also applies its own rounding rules, so your actual increase may differ slightly.
How to Estimate Your Own Increase
Multiply your current gross monthly benefit (before deductions) by the COLA percentage. For example, if your benefit is $1,800 and the COLA is 3.5%, the math is $1,800 × 0.035 = $63. Your new gross benefit would be about $1,863. You can find your current benefit amount in your my Social Security account or your most recent benefit statement.
Social Security COLA History
A mid-3% COLA would be the largest increase since 2023. Here is how recent COLAs compare:
| Year Paid | COLA |
|---|---|
| 2021 | 1.3% |
| 2022 | 5.9% |
| 2023 | 8.7% |
| 2024 | 3.2% |
| 2025 | 2.5% |
| 2026 | 2.8% |
| 2027 (estimate) | 3.2%–3.6% |
Over the past decade, the COLA has ranged from 0% in 2016 to 8.7% in 2023, the highest in four decades. The Social Security Administration says the COLA has averaged about 3.1% over the past 10 years. A 3.5% or 3.6% increase would be a little above that average.
When Will the 2027 COLA Be Announced?
The Bureau of Labor Statistics is scheduled to release September’s inflation data on October 14, 2026. The Social Security Administration is expected to announce the official 2027 COLA that same day, since the September number completes the calculation.
After the announcement, the SSA typically notifies beneficiaries of their new benefit amounts in December. If you have a my Social Security account, you can usually view your COLA notice online, often before a paper letter arrives in the mail.
When Will You Get the 2027 COLA?
The increase applies to benefits for January 2027. Here is when different groups can expect to see it:
| Who | When the Raise Shows Up |
|---|---|
| SSI recipients | With the January 2027 payment, paid on December 31, 2026, because January 1 is a holiday |
| Social Security recipients paid on the 3rd of the month | With the January payment, paid early on December 31, 2026, because January 3 falls on a weekend |
| Birthday on the 1st–10th | Second Wednesday of January 2027 (January 13) |
| Birthday on the 11th–20th | Third Wednesday of January 2027 (January 20) |
| Birthday on the 21st–31st | Fourth Wednesday of January 2027 (January 27) |
Payment dates follow the standard SSA schedule. Always confirm your personal payment date with the SSA, especially around holidays.
Will Medicare Premiums Eat Into Your Raise?
For many retirees, the COLA is only half the story. Medicare Part B premiums are usually deducted directly from Social Security checks, so a higher premium reduces how much of the raise you actually keep.
The 2026 Medicare Trustees Report estimates the standard Part B premium for 2027 at $209.50 a month. The official 2027 premium is usually announced in the fall, often in November.
There is some protection for lower-income beneficiaries. A rule known as the hold-harmless provision generally prevents a Part B premium increase from lowering most people’s net Social Security benefit from one year to the next. However, it does not apply to everyone, including many higher-income beneficiaries who pay income-related surcharges.
Bottom line: plan for your net increase to be somewhat smaller than the COLA math alone suggests.
Does the COLA Really Keep Up With Inflation?
Many retirees feel their costs are rising faster than their benefits. There is some evidence to support that. According to an analysis by The Senior Citizens League, Social Security benefits lost 13.7% of their buying power between 2016 and 2026.
There are a few reasons for the gap:
- Different spending patterns: Retirees spend more on healthcare and housing, costs that often rise faster than the overall CPI-W.
- Timing lag: The COLA is based on last year’s inflation. If prices jump early in the year, retirees wait months for relief.
- Medicare costs: Rising Part B premiums can absorb a large share of each year’s raise.
Other Programs Affected by the 2027 COLA
The Social Security COLA ripples into other federal programs:
- Supplemental Security Income (SSI): SSI payment amounts rise by the same percentage.
- Veterans benefits: VA disability compensation and pension COLAs are typically set to match the Social Security COLA.
- Federal retirees: CSRS retirees usually receive the full Social Security COLA. Under the FERS formula, when the Social Security COLA is above 3%, the FERS COLA is generally the Social Security COLA minus one percentage point. For example, a 3.5% Social Security COLA would mean a 2.5% FERS COLA.
Other Social Security Changes Coming in 2027
The COLA announcement usually comes with other annual updates. Watch for new numbers on:
- Taxable maximum: The maximum earnings subject to Social Security payroll tax is $184,500 in 2026. It usually rises each year.
- Earnings test limits: If you claim benefits before full retirement age and keep working, the income limits before benefits are withheld typically increase.
- Maximum benefit: The maximum possible monthly benefit for people who retire at full retirement age usually rises.
- SSI payment standards: The federal SSI payment amounts for individuals and couples rise with the COLA.
What If September Inflation Surprises?
September is the final piece of the Social Security COLA 2027 puzzle, and it can still move the result. Here are the main scenarios forecasters are watching:
- Inflation holds steady: If September’s CPI-W looks similar to July and August, the COLA will likely land at about 3.5%, in line with most forecasts.
- Energy prices jump: Diesel prices recently climbed to record highs. Diesel powers the trucks and trains that move goods, so higher fuel costs can spread into prices broadly. If that shows up in September’s data, the COLA could come in closer to 3.6% or slightly higher.
- Inflation cools: If prices ease in September, the COLA could slip toward the lower forecasts, near 3.2% to 3.4%.
Because one month makes up a third of the calculation, even a small surprise can shift the final number by a tenth of a percentage point or two.
How the 2027 COLA Affects Different Beneficiaries
The same COLA percentage applies to nearly everyone who receives Social Security or SSI. Here is what it means for each group:
Retired Workers
Retirees make up the largest group of beneficiaries. With an average benefit of about $2,071, a 3.5% COLA would add roughly $72 a month, or about $870 over a full year.
People With Disabilities (SSDI)
Social Security Disability Insurance benefits receive the same percentage increase. The COLA also typically raises the monthly earnings threshold used to judge “substantial gainful activity,” which matters for people who work while receiving disability benefits.
Survivors and Spouses
Widows, widowers, children of deceased workers, and spousal beneficiaries all receive the same COLA percentage on their benefits.
SSI Recipients
SSI is a needs-based program for people with low income and limited resources. The federal SSI payment rises by the same COLA percentage, and recipients see it first, on December 31, 2026.
People Not Yet Claiming
If you have not started benefits yet, COLAs still help you. Once you reach age 62, COLAs are applied to your benefit calculation even if you delay claiming, so your future benefit grows with inflation.
The Bigger Picture: Social Security’s Finances
A larger COLA is good news for beneficiaries, but it also increases the program’s costs. Social Security’s trustees have warned for years that the main retirement trust fund could be depleted in the 2030s if Congress does not act. If that happened, incoming payroll taxes would still cover most, but not all, scheduled benefits.
Lawmakers have discussed options such as raising the payroll tax cap, adjusting the retirement age, or changing the COLA formula. None of these changes affect the 2027 COLA, but they are worth following if you are planning for a long retirement.
Will the COLA Make Your Social Security Taxable?
A bigger benefit can have tax effects. Depending on your “combined income,” which includes half of your Social Security benefits plus other income, up to 85% of your benefits may be subject to federal income tax.
The income thresholds that trigger this tax, starting at $25,000 for single filers and $32,000 for married couples filing jointly, are not adjusted for inflation. That means COLA increases can gradually push more retirees over these limits over time. If you are near a threshold, it may be worth reviewing your withholding or talking with a tax professional.
Key Dates for the Social Security COLA 2027
| Date | What Happens |
|---|---|
| October 14, 2026 | September CPI data released; official 2027 COLA expected |
| Fall 2026 (often November) | Official 2027 Medicare Part B premium announced |
| December 2026 | COLA notices available in my Social Security accounts and by mail |
| December 31, 2026 | SSI recipients receive January payment with the COLA |
| January 2027 | Social Security payments with the COLA arrive based on birth date |
How to Prepare for the 2027 COLA
- Create or log in to your my Social Security account. This is the fastest way to see your COLA notice and confirm your new benefit amount.
- Budget for the net amount, not the gross. Subtract expected Medicare premiums before planning how to spend the raise.
- Review your tax withholding. A higher benefit may slightly change your taxes if your benefits are taxable.
- Check other income sources. Pensions and annuities may have their own adjustment rules.
- Trim fixed costs where possible. Reviewing streaming and phone bills can help your raise go further. For example, see our guides to the Disney Plus price increase and the best prepaid phone plans.
Beware of COLA Scams
Every year around the COLA announcement, scammers contact beneficiaries pretending to be from the Social Security Administration. They may claim you must “verify” your identity or pay a fee to receive your increase.
- The COLA is automatic. You never need to apply or pay anything to receive it.
- The SSA will not threaten you, demand immediate payment, or ask for gift cards or cryptocurrency.
- Never share your Social Security number with an unexpected caller or texter.
Social Security numbers are a top target for identity thieves, as recent incidents like the Pentagon data breach have shown. Our guide to the best identity theft protection services explains how to protect yourself.
