Social Security COLA 2027: What the 3.6% Raise Means

3.6%. That's the Social Security COLA for 2027, and it's no longer a forecast. The Social Security Administration announced it on October 14, 2026. It starts with January 2027 payments for nearly 72 million Social Security beneficiaries. For the average retiree, that's about $75 more a month.

The headline number is the easy part. Whether you actually keep that $75 depends on Medicare, your taxes, which program pays you, and when the deposit arrives. Here's all of it on one page.

Social Security COLA 2027: the short answer

• The raise: 3.6%, up from 2.8% for 2026 (SSA press release, Oct 14, 2026).
• The average retiree check: about $2,095 a month going to about $2,170, a raise of roughly $75 (CNBC Select).
• When: Social Security benefits rise starting in January 2027. SSI recipients get the new amount first, on December 31, 2026.
• The context: The raise is above the 20-year average, according to the American Legion, and the largest since 2023.

Forecasts in the months before the announcement ran between 3.4% and 3.6%, so the final figure landed at the top of that range (Fox Business).

How the number is set

The COLA isn't chosen by anyone. It comes from a formula. SSA compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) in July, August and September with the same three months a year earlier. The percentage change becomes the COLA. Inflation in the third quarter of 2026 set your raise for 2027.

What 3.6% looks like in dollars

A percentage is abstract. Your check isn't. Here's the gross raise at three benefit levels.

Your exact figure will be on the COLA notice SSA sends in December. These are before Medicare comes out.

The Medicare Part B catch

Most retirees on Medicare have the Part B premium taken straight out of their Social Security check. So when the premium goes up, part of the COLA goes with it.

Here's the honest status: As of early November 2026, we couldn't confirm that CMS (the Centers for Medicare & Medicaid Services) had published the final 2027 Part B premium. CMS usually announces it in November. Some websites already call a number "confirmed." Treat those claims with caution until CMS publishes.

What we have are projections:

• $209.50 a month, the Medicare Trustees' projection. That's up $6.60 from $202.90 in 2026 (Medical Daily; AARP).
• $213.05 a month, a higher figure that appears on at least one calculator site. That would be a $10.15 increase.

Here's the take-home math under both:

Either way, most retirees keep the large majority of the raise. We'll update this article when CMS publishes the official premium.

Who the hold-harmless rule protects, and who it doesn't

The hold-harmless provision stops a Part B premium increase from shrinking your net Social Security check below what it was the year before. With a 3.6% COLA, the raise covers the projected premium increase at nearly every benefit level, so most people won't need the protection this year.

You should know who it doesn't cover:

• People who pay IRMAA, the income-related surcharge on Part B for higher earners.
• New Medicare enrollees whose premium wasn't deducted from a Social Security check the year before.
• People whose premium isn't deducted from their check, for example those who pay Medicare directly.

If you're in one of these groups, your premium increase can outrun your raise. Connie Health and medicareguide cover the Medicare side in more detail.

When the raise shows up

The January 2027 payment schedule is where the confusion starts.

Social Security retirement, survivor and SSDI benefits are generally paid on the second, third or fourth Wednesday of the month, depending on your birth date. Secondary sources list January 13, 20 and 27, 2027 (benefitsusa). Check them against SSA's official 2027 calendar.

SSI is paid early. SSI normally arrives on the 1st. January 1, 2027 is a holiday, so the January SSI payment, at the new higher rate, goes out on December 31, 2026 (Cronista).

That creates a familiar worry: "I got two payments in December and nothing in January." Nothing is wrong. The December 31 deposit is your January payment. It just came a day early. Budget it for January.

Key dates checklist

1. December 2026: SSA mails COLA notices. If you have a my Social Security account, you can usually read yours online too.
2. December 31, 2026: First SSI payment at the 2027 rate.
3. January 2027: Social Security payments at the new rate, on your usual Wednesday.
4. If your notice looks wrong: Compare it with your 2026 benefit times 1.036, minus any Medicare change. If it still doesn't add up, contact SSA before the January payment if you can.

Different groups, different numbers

The COLA applies broadly, but some groups have their own figures.

SSI recipients. The maximum federal SSI payment is reported to rise from $994 to $1,029 a month for an individual and from $1,491 to $1,544 for a couple (disabled-world). Those figures come from secondary sources, so confirm them on SSA's SSI amounts page.

SSDI recipients. SSDI is a Social Security benefit, so it gets the same 3.6% raise. Work-related thresholds like the substantial gainful activity limit and the trial work period also adjust each year. Get the 2027 amounts directly from SSA's automatic determinations page.

Federal retirees under FERS. FERS retirees get 2.6%, not 3.6%, because of how that system's COLA formula works when inflation is above 3% (Federal News Network). If you're a federal retiree, don't plan on the Social Security number.

People still working. Two figures from the SSA 2027 fact sheet:

• Taxable maximum: $192,300. Earnings above this aren't subject to the Social Security payroll tax.
• Earnings limit: $67,920 for people reaching full retirement age in 2027. Earn more than that before your full retirement age month, and some benefits are temporarily withheld.

The tax side almost nobody mentions

A bigger benefit isn't always a clean win. Three things are worth checking:

• Taxable Social Security. How much of your benefit is taxed depends on your total income. A higher benefit, on top of other income, can push more of it into taxable territory.
• IRMAA brackets. Medicare surcharges are based on income. If you're close to a threshold, extra income from the COLA or anything else could move you up a bracket.
• Medicare Savings Programs and other assistance. These have income limits. If you're near the cutoff, a raise can affect eligibility.

None of these will matter for everyone. They matter most for people near a line. If that might be you, a tax professional can give you specifics.

Does 3.6% actually keep up?

The COLA follows CPI-W, an index built around the spending of working households. Retirees spend differently. They spend more on health care and housing, for example. That's why some advocates argue for CPI-E, an experimental index weighted toward older Americans' spending. Whether CPI-W under- or over-counts your own costs depends on how you spend.

Health care is the big variable. Fidelity's 2025 Retiree Health Care Cost Estimate (July 2025) puts the cost for one 65-year-old at $172,500 in Medicare premiums, deductibles and prescriptions over retirement, and that excludes long-term care. If your health spending grows faster than general inflation, a COLA that matches CPI-W can still fall behind your real costs.

What this means for your retirement plan

If you haven't claimed yet, the 2027 COLA is a reminder that Social Security is inflation-adjusted income, which is rare. Your benefit estimate grows with each year's COLA. Most of your savings doesn't get that protection automatically.

But one year's raise doesn't tell you much about a 30-year retirement. Inflation, returns and your lifespan all vary. Social Security's own guidance says about 1 in 3 65-year-olds may live to 90 or beyond (SSA, Retirement Information for Medicare Beneficiaries, 2026). A plan that ends at 85 is quietly betting against a third of retirees.

That's why we answer the question with odds instead of a single average. Monte Climb runs your savings, age and monthly spending through 1,000 simulated futures (a Monte Carlo test) and tells you how many of them stay funded. Plans run to age 95 by default, and the engine charges Medicare premiums and income-based surcharges year by year instead of using one flat guess. For reference, Morningstar's The State of Retirement Income 2025 (December 2025) puts the safe starting withdrawal rate at 3.9%, meaning the money lasted in 90% of simulated 30-year retirements.

Frequently asked questions

What is the Social Security COLA for 2027?

It's 3.6%. SSA announced it on October 14, 2026, and it applies to benefits starting with January 2027 payments. The 2026 COLA was 2.8%.

How much will my Social Security check go up in 2027?

Multiply your current monthly benefit by 0.036. The average retiree benefit goes from about $2,095 to about $2,170, a raise of roughly $75 a month, before any Medicare Part B premium change. Your exact amount will be on the COLA notice SSA sends in December.

Will the Medicare Part B increase cancel out the 2027 COLA?

For most retirees, no. The Medicare Trustees project the 2027 Part B premium at $209.50, up $6.60 from $202.90. That's much smaller than the raise at most benefit levels. CMS usually publishes the final premium in November. The hold-harmless rule protects many people, but not IRMAA payers, new enrollees, or people whose premium isn't deducted from their check.

Why did I get two SSI payments in December and none in January?

January 1, 2027 is a holiday, so the January SSI payment, already at the new 2027 rate, is paid early on December 31, 2026. It's your January money, so budget it that way.

Do federal retirees get the full 3.6% COLA?

Not under FERS. Because of how the FERS COLA formula works, FERS retirees get 2.6% for 2027 instead of 3.6%. Their Social Security benefits still get the full 3.6%.
