Every October, the Social Security Administration (SSA) announces the Cost-of-Living Adjustment (COLA) for the following year. The 2026 COLA of 2.8 percent affects more than 72 million Americans receiving Social Security retirement benefits, Social Security Disability Insurance (SSDI), or Supplemental Security Income (SSI). Announced in October 2025, this increase adds approximately $56 per month to the average retired worker’s check beginning January 2026.
Understanding how the COLA is calculated, what it means for your specific benefit, and how it interacts with Medicare Part B premium increases is essential for every beneficiary planning finances in 2026.

How the 2026 COLA Is Calculated
The CPI-W Formula
The COLA is calculated automatically by federal law — not by political decision — using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), produced by the Bureau of Labor Statistics (BLS). The SSA compares the average CPI-W for the third quarter (July, August, September) of the current year to the same period of the prior year. If prices have risen, a COLA equal to the percentage increase is applied.
For 2026, the CPI-W comparison showed a 2.8 percent increase in consumer prices. This is lower than the historic 8.7 percent COLA of 2023 but still represents a meaningful increase for tens of millions of Americans on fixed incomes.
What the 2026 COLA Means in Dollar Terms
| Benefit Category | Before COLA | +2.8% | New Monthly Benefit |
|---|---|---|---|
| Retired worker (average) | $1,927/month | +$54/month | ~$1,981/month |
| Retired couple (both receiving) | $3,014/month | +$84/month | ~$3,098/month |
| Disabled worker (SSDI average) | $1,542/month | +$43/month | ~$1,585/month |
| Survivor (widowed mother + 2 children) | $3,669/month | +$103/month | ~$3,772/month |
| SSI individual maximum | $967/month | +$27/month | $994/month |
| SSI couple maximum | $1,450/month | +$41/month | $1,491/month |
| Maximum benefit (age 70, 2026) | — | — | $4,152/month (record high) |
The Medicare Part B Offset: Your Net Gain May Be Lower
For the majority of Social Security recipients who have their Medicare Part B premium automatically deducted from their benefit, any increase in the Part B premium directly reduces the net dollar gain from the COLA.
For 2026, the Medicare Part B standard monthly premium increased from $185.00 to $202.90 — a rise of $17.90 per month, according to the Centers for Medicare and Medicaid Services (CMS) November 2025 announcement. For a beneficiary receiving the average $54 COLA increase, the net gain after the Part B increase is approximately $36 per month.
The Hold Harmless Provision
Federal law includes a ‘hold harmless’ provision: your net Social Security benefit after the Medicare Part B deduction cannot decrease from one year to the next solely because of a Part B premium increase. However, this protection does not apply to new Medicare enrollees, those paying IRMAA surcharges, or those enrolled in Medicare but not yet receiving Social Security.
IRMAA: Higher Earners Pay More for Medicare in 2026
Social Security recipients with higher incomes pay an Income-Related Monthly Adjustment Amount (IRMAA) surcharge on top of the standard Part B and Part D premiums. In 2026, IRMAA brackets are based on 2024 income reported to the IRS. Surcharges begin for individuals with modified adjusted gross income (MAGI) above $106,000 ($212,000 for married filing jointly).
| 2024 MAGI (Individual) | 2024 MAGI (Joint) | Part B Premium 2026 | Above Standard |
|---|---|---|---|
| $106,000 or less | $212,000 or less | $202.90 | Standard rate |
| $106,001 – $133,000 | $212,001 – $266,000 | $285.00 | +$82.10/month |
| $133,001 – $167,000 | $266,001 – $334,000 | $367.10 | +$164.20/month |
| $167,001 – $200,000 | $334,001 – $400,000 | $449.20 | +$246.30/month |
| $200,001 – $500,000 | $400,001 – $750,000 | $572.90 | +$370.00/month |
| Above $500,000 | Above $750,000 | $596.90 | +$394.00/month |
When COLA Payments Begin and How to Verify Your Amount
The 2026 COLA took effect with the January 2026 payment. Payments follow a birthday-based schedule: beneficiaries born on the 1st–10th receive payment on the second Wednesday; 11th–20th on the third Wednesday; and 21st–31st on the fourth Wednesday. SSI payments are made on the first of each month.
To verify your new benefit amount, log into your my Social Security account at ssa.gov/myaccount. The SSA mailed COLA notices in December 2025. For questions, call 1-800-772-1213 Monday–Friday, 8 a.m.–7 p.m. local time.
How COLA Affects the Social Security Earnings Limit
For beneficiaries who have not yet reached Full Retirement Age (FRA) and continue working, the 2026 COLA also adjusted the earnings limit. In 2026, beneficiaries under FRA for the full year can earn up to $24,480 without benefit reduction. For every $2 earned above this threshold, $1 is withheld. In the year of reaching FRA, a higher limit of $64,680 applies, with $1 withheld for every $3 above the limit.
Benefits withheld due to the earnings test are not lost permanently — they are credited back as a higher monthly benefit once you reach Full Retirement Age.
Frequently Asked Questions
Will everyone receive the same 2.8% increase?
All Social Security and SSI benefits increase by the same 2.8 percent COLA percentage. Because benefits are individually calculated based on work history and filing age, the dollar increase varies from person to person.
Is the COLA increase taxable?
Social Security benefits — including COLA increases — may be partially taxable depending on your combined income (AGI plus tax-exempt interest plus half of Social Security benefits). Up to 85 percent of benefits can be taxable for individuals with combined income above $34,000 or married couples above $44,000. The new $6,000 senior deduction under the OBBBA may reduce this burden for some recipients in 2026 and 2027.
Can the COLA ever be zero?
Yes. If consumer prices do not rise, the COLA can be zero. This occurred in 2010, 2011, and 2016. By law, Social Security benefits cannot decrease because of a zero COLA, though hold harmless provisions have specific limitations.
Where can I find my official COLA notice?
Your COLA notice is available in your my Social Security account at ssa.gov/myaccount under ‘Messages.’ The SSA also mailed paper notices in December 2025. Call 1-800-772-1213 Monday–Friday, 8 a.m.–7 p.m., to request your benefit information.
