Social Security just gave you a 3.6% raise. Here is what it actually buys.

The short version: On October 14, Social Security announced a 3.6% cost-of-living adjustment for 2027, the largest since 2023, worth about $75 a month for the average retiree. That is real money and worth being glad about. It is also gross, not net. Three things come out before it reaches you: the Medicare premium, which is deducted first; the tax on benefits, whose thresholds have not moved since the 1980s; and the inflation the raise was meant to cover in the first place. None of this is a reason for alarm. It is a reason to know your own number rather than the headline one.

A client we will call Diane called the week the announcement came out. She had seen "3.6%" on the news and wanted to know what it meant for her. Fair question, and the honest answer has three parts.

Part one: the raise is real

Social Security confirmed that benefits for 76 million Americans rise 3.6% beginning in January 2027. For the average retirement benefit that is roughly $75 a month, or about $900 a year. Last year's adjustment was 2.8%, so this is a meaningful step up.

The number comes from a formula, not a decision. It tracks a specific inflation index over the third quarter of the year, which is why it lands in October every year without anyone voting on it.

One practical note. If you want to see your personal new amount early, Social Security will post individual notices online in late November for anyone with a my Social Security account. You need to have the account set up by November 18 to get the notice that way. Otherwise it comes by mail in December.

Part two: Medicare takes its share first

For most retirees the Part B premium is deducted straight from the Social Security check before it arrives. The 2026 standard premium is $202.90 a month. The 2027 figure had not been published as of this writing, but it rises most years, and whatever the increase turns out to be, it comes off the top of your COLA.

So if your raise is $75 and Part B rises by, say, $7, you keep $68. Not dramatic. But worth knowing, because the headline number is not the number that lands in your account.

Part three: the tax thresholds that never move

This is the piece almost nobody explains.

Whether your Social Security is taxable depends on something called provisional income, which is roughly your other income plus half your benefits. If that figure clears $25,000 for a single filer, up to half your benefits become taxable. Above $34,000, up to 85% do.

Those thresholds were set in 1983 and 1993. They have never been adjusted for inflation. Every year, a cost-of-living increase pushes a few more people across lines that were drawn when a dollar bought considerably more. A raise designed to keep pace with prices can, by itself, make more of your benefit taxable.

For a woman living mostly on Social Security, this does not matter much. For a woman with a pension, a part-time income, or withdrawals from a retirement account, it can matter quite a bit, because every dollar of the raise arrives on top of income that is already pushing against those lines.

What the raise was for

The reason the COLA exists is that prices went up. The adjustment is not a bonus. It is an attempt to hold your purchasing power roughly level.

Whether 3.6% actually does that depends on what you buy. The index Social Security uses weights things like gasoline and groceries. If your spending tilts toward healthcare, housing, or insurance, your personal inflation rate may be running higher than the official one, and the raise covers less of it than the headline suggests.

The bottom line

Diane's raise was real, and it was welcome. Her net raise, after the Part B deduction and a slightly larger slice of her benefit becoming taxable, was closer to $55 than $75. Still worth having. Just worth knowing.

The useful habit here is simple: when a headline number arrives, ask what comes out before it reaches you. That is true of a COLA, a pension increase, a required distribution, and most of the other numbers that show up in retirement. The gross figure is the one on the news. The net figure is the one you live on.

Every story is different, and every plan worth its name reflects that. If you would like to talk through what is going on in your world, our strategy session is forty-five minutes, virtual, and meant for listening, not selling. Nothing is decided in the room.
