Why Social Security Payments Could Jump Significantly in 2027
What drives Social Security payment increases
Social Security payments rise each year based on cost-of-living adjustments, or COLAs. The Social Security Administration calculates a COLA by measuring inflation using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). When prices rise faster than they did the year before, the COLA percentage goes up, and so do monthly payments for everyone receiving Social Security, SSI, or SSDI.
The COLA for any given year is announced in October and takes effect the following January. So the 2027 COLA will be announced in October 2026 and will change payments starting in January 2027. The size of that increase depends entirely on what inflation looks like between now and September 2026—no one can predict it with certainty, which is why talk of a "large" increase is based on economic forecasts, not guarantees.
Recent years have shown how much COLAs can vary. The 2024 COLA was 3.2 percent. The 2025 COLA was 2.5 percent. Both were significantly higher than the average COLA of roughly 1.3 percent over the 20 years before 2021. If inflation stays elevated or rises again, the 2027 COLA could be larger than recent years.
Key Takeaways
- Social Security payments increase each January based on inflation measured from October of the previous year through September of the current year.
- The 2027 COLA will be announced in October 2026 and will depend on inflation trends between now and September 2026.
- Recent COLAs have ranged from 2.5 to 3.2 percent, well above the historical average of about 1.3 percent.
- A larger COLA means higher monthly payments for all Social Security, SSI, and SSDI recipients, but also affects Medicare premiums and other benefit calculations.
How inflation between now and September 2026 will determine the 2027 increase
The COLA formula compares the average CPI-W for July, August, and September of the current year to the average for the same three months in the previous year. For the 2027 COLA, the Social Security Administration will compare the average CPI-W from July–September 2026 to the average from July–September 2025.
If prices rise faster during that period than they did in the same months a year earlier, the COLA will be larger. If prices rise more slowly or fall, the COLA will be smaller. Economists and forecasters make educated guesses about what inflation will look like, but actual inflation depends on many factors—energy prices, employment, consumer spending, and Federal Reserve policy all play a role.
This is why predictions about a "large" 2027 COLA are based on current economic models, not on what will actually happen. Some forecasters expect inflation to remain moderate; others worry it could tick upward. The actual number will not be known until October 2026.
What a larger payment means for your monthly budget
If the 2027 COLA is larger than recent years, your monthly Social Security, SSI, or SSDI payment will increase starting in January 2027. The exact dollar amount depends on your current benefit level. Someone receiving $1,500 per month would see a different dollar increase than someone receiving $3,000 per month, even though the percentage increase is the same.
A larger COLA also affects other programs tied to Social Security. SSI federal benefit rates increase with the COLA. Medicare Part B premiums (for doctor and outpatient care) are adjusted based on Social Security's COLA, though the adjustment is complex and does not always match the percentage increase. Supplemental Security Income (SSI) state supplements, where they exist, may also adjust based on the COLA.
The increase is automatic—you do not need to do anything to receive it. If you have direct deposit set up, the new amount will appear in your bank account on the third day of the month (or the first business day after if the third falls on a weekend or holiday).
How to prepare for payment changes in 2027
You can review your current Social Security payment amount by logging into your my Social Security account at ssa.gov. This account shows your monthly benefit, your earnings record, and an estimate of what you will receive at different ages if you have not yet claimed. Checking this information now helps you understand your baseline before any 2027 increase takes effect.
If you receive SSI or SSDI, your payment notice will arrive in December 2026 showing your new January 2027 amount. If you receive Social Security retirement or survivor benefits, you will receive a notice in December as well. These notices are mailed automatically; you do not need to request them.
If your income or living situation has changed, now is a good time to review whether you are receiving all the benefits you may be may have access to to. Changes in income, housing, or family status can affect SSI amounts or whether you may have access to for other programs. You can contact your local Social Security office or call 1-800-772-1213 to discuss your situation.
The difference between a COLA and a benefit increase from other causes
A COLA is not the only reason a Social Security payment might increase. If you are still working and have not yet claimed benefits, your benefit amount grows each year you continue to work, because Social Security calculates benefits based on your highest 35 years of earnings. If you claimed benefits early and reach your full retirement age, your benefit may increase due to a different formula (called the Government Pension Offset or Windfall Elimination Provision, depending on your situation).
If you are receiving SSDI and you return to work, your payment may change based on work incentive rules that allow you to earn money while still receiving benefits. These changes are separate from the COLA and happen on different schedules. The COLA is the annual inflation adjustment that affects everyone receiving benefits at the same time, every January.
Why economists watch the 2027 COLA closely
The size of the COLA matters to millions of people. Social Security is the primary income source for about 40 percent of people over 65. For SSI recipients, the federal benefit rate is often the only income they have. A larger COLA means more money for groceries, rent, utilities, and medicine. A smaller COLA means less breathing room in an already tight budget.
Economists and policy analysts also watch the COLA because it affects the long-term finances of the Social Security trust fund. A larger COLA means the program pays out more money each month. Over time, this affects when the trust fund reserves are projected to run down, which is why the COLA is part of ongoing debates about Social Security's future.
For now, the 2027 COLA remains unknown. The announcement will come in October 2026, and the increase will take effect in January 2027. Staying informed about your current benefit amount and understanding how COLAs work puts you in a better position to plan your budget and understand what changes are coming.
Frequently Asked Questions
Will I automatically receive the 2027 COLA increase, or do I need to do something?
The increase is automatic. You do not need to contact Social Security or take any action. If you have direct deposit, the new amount will appear in your account on the third of the month (or the first business day after). If you receive a paper check, it will reflect the new amount.
When will I know what the 2027 COLA percentage is?
The Social Security Administration announces the COLA in October of the year before it takes effect. The 2027 COLA will be announced in October 2026. You can find the announcement on ssa.gov or by calling 1-800-772-1213.
Does a larger COLA mean my Medicare premiums will also increase?
Medicare Part B premiums are adjusted based on Social Security's COLA, but the relationship is complex. In some years, the premium increase is smaller than the COLA because of how the adjustment formula works. Your Medicare premium notice will arrive in December 2026 showing what you will pay in 2027.
What if I am receiving both Social Security and SSI?
Both payments will increase with the 2027 COLA. However, if your Social Security increase pushes your total income above the SSI limit, your SSI payment may decrease or stop. Contact your local Social Security office if you receive both benefits and want to understand how the increase will affect your total monthly income.
Can I find out what my payment will be in 2027 before October 2026?
No one can know the exact amount until the COLA is announced. However, you can estimate by taking your current payment and multiplying it by different COLA percentages. If you receive $2,000 per month and the COLA is 3 percent, your new payment would be roughly $2,060. Your my Social Security account shows your current amount, which is the starting point for any calculation.
