Social Security benefits rose 2.8% for 2026, but that does not guarantee your monthly deposit will rise by exactly 2.8%. The COLA changes the benefit calculation; Medicare premiums, earnings-test withholding, and the way SSA rounds the final amount can affect what you receive. Your personalized 2026 COLA notice shows your new benefit and listed deductions.
What the 2026 Social Security raise does—and does not—mean
The Social Security Administration (SSA) announced a 2.8% cost-of-living adjustment (COLA) for 2026, based on the increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of 2024 to the third quarter of 2025. Benefits with the adjustment began in January 2026. SSA’s 2026 COLA announcement describes the adjustment.
The COLA is applied to your primary insurance amount, a figure used to calculate your retirement benefit. The amount payable can differ because of when you claimed, deductions, and final rounding. The COLA is therefore not a promise that the amount deposited in your bank account will increase by precisely 2.8%. SSA explains the calculation in its retirement-benefit COLA example.
Reasons your deposit may rise by less
Medicare premiums can take a larger deduction
If you have Medicare premiums deducted from Social Security, a premium increase can absorb some of your COLA. The standard Medicare Part B premium is $202.90 per month in 2026. Some people pay more because of income-related adjustments, and Medicare premiums can be withheld from Social Security benefits. Compare the Medicare deduction on your COLA notice with last year’s amount, and check SSA’s Medicare premium information for current rates and income-related amounts.

Retirement timing and rounding affect the final figure
Your benefit reflects more than the COLA percentage: SSA applies the adjustment to your primary insurance amount, accounts for the effect of early or delayed retirement, subtracts applicable offsets, and truncates the final amount to the next lower dollar. SSA identifies a Medicare Supplementary Medical Insurance premium as one example of an offset. These calculation steps can make the dollar change differ slightly from a simple 2.8% multiplication.
Working before full retirement age can lead to withholding
If you are below full retirement age and earn above the applicable limit, the retirement earnings test can cause SSA to withhold benefits. The 2026 limits and withholding rates depend on whether you reach full retirement age during the year:
| Situation in 2026 | Earnings limit | Withholding rule |
|---|---|---|
| Below full retirement age for all of 2026 | $24,480 for the year | $1 in benefits withheld for every $2 of earnings above the limit |
| Reach full retirement age during 2026 | $65,160, counting earnings only before the month you reach full retirement age | $1 in benefits withheld for every $3 of earnings above the limit |
There is no earnings limit beginning with the month you reach full retirement age. These are SSA’s 2026 retirement earnings-test rules. Withholding under the earnings test is distinct from the COLA calculation and can change the amount paid while you are working.
How to find the reason for your specific increase
- Open your personalized COLA notice. SSA says the simplified notice lists your new benefit amount and deductions. Most beneficiaries can view it in the Message Center of their my Social Security account. SSA provides more information about COLA notices.
- Compare the gross benefit and every deduction. Look at the prior and new amounts separately rather than comparing only the bank deposit. Note any Medicare premium or other deduction shown on the notice.
- Check Medicare charges if you are enrolled. Compare the amount withheld with the current premium information and any income-related adjustment that applies to you.
- Check the earnings test if you are working and below full retirement age. Use the limit and timing rule that match when you reach full retirement age in 2026.
- Ask SSA if the notice does not account for the difference. Use SSA’s official contact information rather than assuming the COLA percentage explains your payment.
Why an average raise may not match yours
SSA estimated that the average retired-worker benefit would rise from $2,015 to $2,072 per month after the 2026 COLA—a $57 increase—using actual benefit data through August 2025. That is an estimate for an average beneficiary, not a forecast of your personal payment. Your own benefit and deductions determine your amount. See SSA’s 2026 COLA fact sheet for the estimate.
