Social Security's 3.6% raise for 2027: what it changes in your plan
Social Security benefits go up 3.6% starting with January 2027 payments, the largest raise in four years. On average a retired worker gets about $75 more a month (SSA, Oct 14, 2026).
1. What the raise is
Each October, Social Security compares prices from July through September with the same months a year earlier, and raises benefits by that amount in January. It's called the cost-of-living adjustment, or COLA. It keeps your benefit buying the same groceries and paying the same bills as prices rise.
On a $2,800 monthly benefit, 3.6% is about $101 more a month in 2027.
2. Why your plan's number doesn't move
MangoDime shows everything in today's dollars: what your retirement paycheck would buy at today's prices. A raise that matches inflation keeps that paycheck exactly where it was. So if your plan said Social Security pays you $2,800 a month in today's dollars, it still does.
Few other sources of retirement income rise with prices automatically and for life. A pension with no COLA, or an annuity with a fixed payment, buys a little less every year.
3. You get the raise even if you haven't claimed yet
If you're 62 or older and waiting to claim, this raise still applies to the benefit you'll get later. COLAs count from the year you turn 62, whether or not you've started. Waiting doesn't cost you the raise.
If you're younger than 62, the raise doesn't apply to you directly. Your future benefit is tied mostly to wage growth until about 60 instead.
4. Two things that can take part of it back
Medicare premiums. If you're on Medicare, the Part B premium usually rises in January too, and it comes out of your Social Security check. The 2027 amount isn't announced yet; Social Security says it will post it in late November. A rule called hold harmless stops the premium increase from shrinking most people's check below last year's.
Taxes on your benefit. Up to 85% of Social Security can be taxed, depending on your other income plus half your benefit. The cutoffs for that test ($25,000 single, $32,000 married) have never been raised for inflation. As benefits rise, more retirees cross them each year, and a little more of each raise goes to tax.
5. What to do with it
For most people planning ahead, nothing changes. Your plan in today's dollars already assumed benefits keep pace with prices.
Two things are worth a look:
- If you're already collecting, check the new amount in your my Social Security account in December, and whether your tax withholding still fits.
- If you're deciding when to claim, the raise doesn't change the comparison between ages, because every claiming age gets the same 3.6%.

What this doesn't model
- MangoDime assumes future raises match inflation exactly. In some years they run ahead or behind.
- The $25,000 and $32,000 cutoffs stay at today's value in every year of the plan, as if they rose with prices. In reality they don't, so in later years a little more of your benefit is taxed than the plan shows.
- The Part B premium is estimated, not the announced 2027 figure.
