On October 14, 2026, the Social Security Administration officially confirmed a 3.6% cost-of-living adjustment (COLA) for 2027 — the largest increase since 2023, and well above 2026’s 2.8% bump. If you’re wondering exactly how much more you’ll see in your check, the short answer is: multiply your current monthly benefit by 1.036. A $2,000 check becomes $2,072 (a $72 monthly raise), and the “average” retired worker benefit of roughly $2,071 rises to about $2,145, an increase of around $74 a month. Use the Social Security COLA calculator to plug in your exact benefit and get your precise new amount, including what’s left after any Medicare premium increase.
What the 2027 COLA Means for Your Check
Every fall, the SSA announces next year’s COLA by comparing the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) across July, August, and September of the current year to the same three months of the prior year. The resulting percentage becomes the raise applied to Social Security retirement, survivors, and disability (SSDI) benefits, as well as SSI payments.
This year’s 3.6% figure is notably higher than recent years, driven in large part by energy-price increases. Here’s how it stacks up against recent history:
| Year | COLA | Context |
|---|---|---|
| 2023 | 8.7% | Highest in four decades, post-pandemic inflation spike |
| 2024 | 3.2% | Inflation cooling from its 2022-23 peak |
| 2025 | 2.5% | Near-typical adjustment |
| 2026 | 2.8% | Slightly above the 2025 rate |
| 2027 | 3.6% | Largest increase since 2023, driven partly by energy prices |
How Much Will Your Check Actually Increase?
The math is simple: new benefit = current benefit × 1.036. Here’s what that looks like across a range of common benefit amounts:
| Current Monthly Benefit | Monthly Increase | New Monthly Benefit |
|---|---|---|
| $800 | $28.80 | $828.80 |
| $1,000 | $36.00 | $1,036.00 |
| $1,500 | $54.00 | $1,554.00 |
| $2,000 | $72.00 | $2,072.00 |
| $2,500 | $90.00 | $2,590.00 |
| $3,000 | $108.00 | $3,108.00 |
Rather than doing the multiplication by hand, enter your exact current benefit into the Social Security COLA calculator to see your new monthly amount, your annual increase, and — if you expect your Medicare premium to rise — your real net raise after that’s deducted.
When You’ll Actually See the Increase
The COLA doesn’t land in every benefit type’s payment at the same time:
- Retirement, survivors, and SSDI benefits: your new amount starts with your January 2027 payment.
- SSI payments: the increase arrives a little earlier, in your December 31, 2026 payment, because of how the SSI payment calendar works.
- Your personal notice: the SSA mails COLA notices in early December. If you’d rather see it online first, create (or log into) your “my Social Security” account by November 18, 2026 to view your notice digitally instead of waiting for the mail.
The Catch: Medicare Part B Premiums
A 3.6% headline COLA doesn’t always translate into a 3.6% bump in your actual deposit. For most retirees, the Medicare Part B premium is deducted directly from your Social Security check before it ever reaches your bank account. If that premium rises for 2027 — and CMS typically doesn’t finalize the new Part B premium until November — part of your gross raise effectively goes toward covering the higher premium instead of your spending money.
A couple of other wrinkles worth knowing about:
- CPI-W vs. retiree spending: the COLA is based on CPI-W, which tracks spending by urban wage earners and clerical workers, not retirees specifically. Retirees tend to spend a larger share of their budget on medical care, so some advocacy groups argue the COLA formula understates the inflation retirees actually experience.
- SSI interactions: if you receive both Social Security and SSI, your total increase isn’t always a simple 3.6% bump on both checks — an increase in your regular Social Security benefit can affect how your SSI payment is calculated.
Because of this, it’s worth running your numbers through the Social Security COLA calculator with an estimated Part B increase once CMS publishes the 2027 premium, so you know your real take-home raise rather than just the headline percentage.
Building the Raise Into Your 2027 Budget
Once you know your new benefit amount, the next step is making sure it actually fits into your broader financial picture:
- Recalculate your full retirement income. If you’re also drawing from an IRA, 401(k), or pension, use the Social Security calculator to see how your COLA-adjusted benefit interacts with your claiming-age strategy and any spousal benefits.
- Update your monthly budget. Plug your new net benefit (after any Part B premium) into the budget calculator alongside your other income sources and expenses to see whether the raise changes how much you can comfortably spend or save each month.
- Watch for other 2027 figures still pending. The 401(k) contribution limit and the 2027 Health FSA limit are both still unannounced as of this guide’s publication and typically arrive in late October or November — worth revisiting once those are official too.
Frequently Asked Questions
What is the Social Security COLA for 2027? 3.6%, officially announced by the SSA on October 14, 2026. It’s the largest increase since 2023’s 8.7% and up from 2.8% in 2026.
How do I calculate my exact new benefit? Multiply your current monthly benefit by 1.036. For example, $1,800 × 1.036 = $1,864.80, a $64.80 monthly increase. Or just enter your amount into the Social Security COLA calculator for an instant answer.
When does the 2027 COLA take effect? Retirement, survivors, and SSDI benefits reflect it starting with the January 2027 payment. SSI payments see it a bit sooner, in the December 31, 2026 payment.
Will my Medicare premium cancel out my raise? It can reduce it, since Part B premiums are typically deducted directly from your check. CMS usually finalizes the 2027 Part B premium in November — once you know it, you can enter the increase into the calculator to see your net raise after the deduction.
Does everyone get the same 3.6% increase? The percentage is the same for everyone, but the dollar amount scales with your current benefit — someone receiving $3,000 gets a larger dollar increase ($108) than someone receiving $1,000 ($36), even though both get the same 3.6%.
The Bottom Line
The 2027 Social Security COLA is officially 3.6%, the biggest raise beneficiaries have seen since 2023. The math is straightforward — multiply your current check by 1.036 — but your real take-home increase depends on what happens to your Medicare Part B premium along the way. Use the Social Security COLA calculator to get your exact new monthly and annual benefit, cross-check your full retirement income picture with the Social Security calculator, and plug your updated numbers into the budget calculator to see how the raise fits into your 2027 spending plan.
