Social Security COLA 2027: How Much Your Check Will Change in January

Social Security benefits will rise 3.6% in 2027. The Social Security Administration (SSA) announced the 2027 cost-of-living adjustment (COLA) on October 14, 2026. It applies to roughly 72 million Social Security beneficiaries and about 7.3 million people who receive Supplemental Security Income (SSI). Here is what the raise means in real dollars, when the new amount lands in your account, and what could take a bite out of it.

The 2027 COLA at a glance

For the typical retired worker, that works out to roughly $75 more per month, according to SSA estimates.

Why this raise is bigger than last year's

The COLA is set by formula, not by Congress. SSA compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) for July, August and September with the same three months a year earlier. Inflation picked up during 2026, with gasoline prices a major driver, and the formula produced 3.6%.

That is the largest increase since 2023, when benefits jumped 8.7%. For comparison, the COLA was 3.2% for 2024, 2.5% for 2025 and 2.8% for 2026. Keep in mind that the COLA is meant to keep pace with prices you already paid, not to get ahead of them. If your own costs, such as rent, insurance or prescriptions, rose faster than the national average, the raise may still feel thin.

How much will your check change?

The quick math: multiply your current gross monthly benefit (before any Medicare deduction) by 0.036. Here is what that looks like at common benefit levels.

Your official figure may differ by a dollar or so. SSA applies the increase to your underlying benefit amount and then rounds the monthly payment down to the whole dollar.

When the higher amount arrives

The 3.6% applies to benefits for December 2026, which are paid in January 2027. Because January 1 is a federal holiday, some people will see the raise before the new year:

• SSI recipients: the first higher payment arrives on Thursday, December 31, 2026.
• People paid on the 3rd of the month (generally those who started benefits before May 1997 or who receive both Social Security and SSI): January's payment also arrives on December 31, 2026, because January 3 falls on a Sunday.
• Everyone else is paid on a Wednesday based on birth date: January 13 (born on the 1st–10th), January 20 (11th–20th) or January 27 (21st–31st).

Watch for your COLA notice

SSA says personalized COLA notices will be available online in late November 2026, in the Message Center of your my Social Security account, for most people who create an account by November 18, 2026. Paper notices arrive by mail in December. The notice shows your new gross benefit, any Medicare premium deducted and your net payment. It is worth reading line by line, because it is the first place an error would show up.

What Medicare may take back

For most retirees, the Medicare Part B premium is deducted straight from the Social Security check, so the net raise depends on next year's premium. The standard Part B premium is $202.90 a month in 2026. The 2027 amount had not been announced as of mid-October; the 2026 Medicare Trustees Report projected roughly $209.50. If that projection holds, the premium would absorb about $6.60 of a typical raise.

Two protections and one exception apply:

• Hold harmless: for most people whose Part B premium is deducted from Social Security, a premium increase cannot be larger than the dollar increase in their benefit, so the net check should not go down.
• Help with premiums: people with limited income and savings may qualify for a Medicare Savings Program through their state, which can pay the Part B premium entirely.
• Higher earners: people who pay income-related surcharges (IRMAA) are not covered by hold harmless and could see a smaller net increase.

Drug plan and Medicare Advantage premiums can change too. Open enrollment runs through December 7, and our guide to seven Medicare changes to check before 2027 walks through what to compare.

Taxes on a bigger benefit

Up to 85% of Social Security benefits can be subject to federal income tax, depending on your "combined income" (adjusted gross income plus nontaxable interest plus half of your benefits). The thresholds, $25,000 for single filers and $32,000 for married couples filing jointly, have never been adjusted for inflation, so each COLA nudges more retirees over the line.

Two things can soften that. For tax years 2025 through 2028, taxpayers age 65 and older can claim an additional deduction of up to $6,000 per person, which phases out at higher incomes. And if you would rather not owe a lump sum in April, you can ask SSA to withhold federal tax from each payment using Form W-4V, at 7%, 10%, 12% or 22%.

If you still work and collect benefits

If you are younger than full retirement age for all of 2027, SSA withholds $1 in benefits for every $2 you earn above $25,560. In the year you reach full retirement age, the limit rises to $67,920 and SSA withholds $1 for every $3 above it, counting only earnings before the month you reach that age. Withheld benefits are not lost: your monthly amount is recalculated upward once you reach full retirement age.

Your 2027 checklist

1. Create or log in to your my Social Security account and check the Message Center in late November for your new gross and net amounts.
2. Update your budget using the net figure, after Medicare premiums.
3. Compare Medicare drug and Advantage plans before December 7.
4. If you make estimated tax payments or have tax withheld, recheck the amounts for 2027.
5. If you are close to the earnings limit, plan your work income for the year.
