The 2026 COLA will likely be smaller than recent years, probably between 2% and 3%

The Social Security cost-of-living adjustment (COLA) for 2026 has not been announced yet — the Social Security Administration releases the official figure in October of the prior year. However, economists and policy analysts make forecasts based on inflation data from the first nine months of the year. Current forecasts suggest the 2026 COLA will fall somewhere between 2% and 3%, which would be a significant drop from the 8.7% increase in 2023 and the 3.2% increase in 2024.

The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), measured from the third quarter of one year to the third quarter of the next. Because inflation has cooled from its 2022 peak, the adjustment is expected to be more modest. The exact percentage will depend on inflation data released between now and September 2025, so forecasts may shift as new economic reports come in.

Key Takeaways

  • The 2026 COLA will be announced in October 2025 and takes effect in January 2026, affecting both current beneficiaries and those newly claiming that month.
  • Forecasts currently point to a COLA between 2% and 3%, down from the 8.7% increase beneficiaries received in 2023.
  • The COLA is tied to inflation measured by the CPI-W from July through September of the prior year, so it cannot be predicted with certainty until late in that year.
  • A smaller COLA means smaller monthly benefit increases, but also typically signals lower inflation overall, which affects the cost of living for retirees.

How the COLA is calculated and announced

The COLA formula is straightforward: the Social Security Administration compares the average CPI-W for July, August, and September of one year to the same three months in the previous year. If inflation has occurred, beneficiaries receive a percentage increase equal to that inflation. If there is no inflation or prices have fallen, the COLA is zero — there is no negative adjustment.

The announcement happens every October 15th. Once announced, the COLA takes effect on January 1st of the following year. This means the 2026 COLA will be announced on October 15, 2025, and will be reflected in benefit payments starting in January 2026. Anyone who begins claiming Social Security in January 2026 or later will receive their initial benefit at the 2026-adjusted rate.

Why 2026 forecasts are lower than recent years

From 2021 through 2023, inflation spiked due to pandemic-related supply chain disruptions, increased consumer demand, and fiscal stimulus. This produced the largest COLA increases in four decades — 5.9% in 2022 and 8.7% in 2023. Since then, the Federal Reserve raised interest rates to cool inflation, and price growth has slowed considerably. Inflation measured by the CPI-W has moderated from those peaks, which is why forecasters expect a smaller adjustment for 2026.

A lower COLA is not necessarily bad news for retirees. While the monthly benefit increase will be smaller, a lower COLA also reflects lower overall inflation, meaning the cost of groceries, utilities, and other living expenses is rising more slowly. The real purchasing power of the benefit — what it can actually buy — depends on both the COLA and the inflation rate in the broader economy.

What a 2% to 3% increase means for your monthly benefit

The COLA is applied as a percentage to your full benefit amount. If you receive $1,500 per month and the COLA is 2.5%, your new monthly benefit would be $1,537.50. If the COLA is 3%, you would receive $1,545. The exact dollar increase depends on your current benefit amount — higher benefits receive larger dollar increases, even though the percentage is the same for everyone.

The increase takes effect in January, so you will see it reflected in your first payment of that month. If you receive benefits by direct deposit, the money will appear in your bank account on the usual payment date. If you receive a paper check, it will arrive with the new amount. There is no action required on your part to receive the COLA — it is applied automatically to all beneficiaries.

Forecasts can change as new data arrives

Current forecasts of 2% to 3% are based on inflation data available through mid-2025. The actual COLA depends on CPI-W figures from July, August, and September 2025, which will not be released until later in the fall. If inflation accelerates or decelerates unexpectedly during those months, the forecast will shift. Major economic events — a recession, a spike in energy prices, or significant changes in employment — could move the final number up or down.

For this reason, forecasts released now should be treated as estimates, not guarantees. Financial advisors and policy analysts will refine their predictions as September 2025 approaches and more complete inflation data becomes available. The Social Security Administration's official announcement in October 2025 will be the definitive figure.

How the COLA affects your taxes and Medicare premiums

The COLA increase is applied to your benefit amount, but it also affects the income thresholds that determine whether your benefits are taxable. If your combined income (adjusted gross income plus nontaxable interest plus half your Social Security benefits) exceeds certain thresholds, a portion of your benefits becomes subject to federal income tax. Those thresholds are adjusted annually but do not rise as quickly as the COLA, so more beneficiaries may owe taxes on their benefits over time.

Medicare Part B and Part D premiums are also adjusted annually, though not always by the same percentage as the COLA. In some years, the COLA increase is large enough that it fully covers the premium increase; in other years, beneficiaries see a net decrease in their take-home benefit. The relationship between the COLA and premium increases is complex and varies year to year, so it is worth reviewing your Medicare costs in December when the new rates are announced.

Planning around an uncertain COLA

If you are still working and deciding when to claim Social Security, a smaller COLA does not change the fundamental math of claiming early versus waiting. Claiming at 62 gives you smaller monthly payments for a longer period; claiming at 70 gives you larger monthly payments for a shorter period. The COLA applies to both scenarios equally, so the trade-off remains the same regardless of whether the adjustment is 2% or 8%.

If you are already receiving benefits, a modest COLA means your benefit will grow more slowly than it did in recent years, but it will still grow. Over a long retirement, even small annual increases compound. If you are budgeting for 2026, using a conservative estimate of 2% to 3% is reasonable and will help you avoid overestimating your income.

Frequently Asked Questions

When will the 2026 COLA be officially announced?

The Social Security Administration announces the COLA every October 15th. The 2026 COLA will be announced on October 15, 2025, and will take effect on January 1, 2026.

Can the COLA ever be negative?

No. If inflation is zero or prices fall, the COLA is zero, and benefits do not decrease. There has never been a negative COLA in Social Security history, though there have been years with zero adjustment.

Does the COLA apply to Supplemental Security Income (SSI) as well?

Yes. SSI recipients receive the same COLA adjustment as Social Security beneficiaries, applied to their federal benefit amount. Some states add their own supplement to SSI, and those state amounts may have different adjustment rules.

If I claim Social Security in January 2026, will my initial benefit include the 2026 COLA?

Yes. Anyone who claims in January 2026 or later will receive their initial benefit calculated at the 2026-adjusted rate. The COLA is built into the benefit calculation for all new claims starting that month.

How does the COLA affect my spouse's or survivor's benefits?

The COLA applies to all types of Social Security benefits — retirement, spousal, survivor, and disability. If you receive a benefit based on someone else's earnings record, your benefit increases by the same percentage as the primary beneficiary's benefit.
