Early estimates put the 2027 Social Security cost-of-living adjustment (COLA) at 3.5% to 3.6%, which would be the largest increase since 2023. The Social Security Administration confirms the official number on October 14, 2026, based on third-quarter inflation data — but you can already convert that percentage into real dollars for your own benefit and start adjusting your monthly budget now instead of waiting for the announcement.
What the 2027 COLA Estimate Actually Means in Dollars
A percentage alone does not tell you much until you apply it to your specific benefit. Here is what a 3.5% raise looks like at different benefit levels:
| Current Monthly Benefit | +3.5% COLA | +3.6% COLA |
|---|---|---|
| $1,400 | $1,449 | $1,450 |
| $1,800 | $1,863 | $1,865 |
| $2,085 (national average) | $2,158 | $2,160 |
| $2,600 | $2,691 | $2,694 |
| $3,200 | $3,312 | $3,315 |
For the average retired-worker benefit of roughly $2,085 a month, a 3.5% COLA works out to about $73 more per month, or just under $900 more for the year. That is the number to plug into your actual budget — not the headline percentage.
Why Your Real Increase Will Be Smaller Than the Headline Number
The COLA percentage is not the amount that lands in your account. Two things typically eat into it before you see the difference:
- Medicare Part B premiums. For most retirees, the Part B premium is deducted directly from the Social Security payment before it is deposited. When Medicare premiums rise in the same year as a COLA increase — which happens most years — part of your raise is absorbed before you ever see it.
- Taxes on benefits. If your combined income (adjusted gross income, plus nontaxable interest, plus half your Social Security benefit) crosses certain IRS thresholds, a portion of your Social Security becomes taxable. A COLA increase can push some retirees slightly further into taxable territory.
The practical takeaway: budget using your net deposit amount once it actually changes, not the gross percentage from the news.
How to Update Your Budget Once the COLA Is Official
Step 1: Wait for your official benefit letter
The Social Security Administration mails (or posts to your my Social Security account) a COLA notice in early December, showing your exact new benefit amount for January. Do not adjust your budget based on the October estimate — use the December notice, since it already accounts for your Medicare Part B premium deduction.
Step 2: Log the new amount as your income line, not a windfall
Once your January payment reflects the new amount, update your income entry in whatever system you track your finances in. If you use Tefteri, that means editing your recurring income entry to the new deposit amount so every month going forward reflects reality instead of the old figure.
Step 3: Decide where the increase goes before you spend it
An extra $73 a month feels small enough to disappear into everyday spending without a decision. Before your first higher payment arrives, decide in advance whether it goes toward rising grocery costs, an emergency fund, or a specific bill that has been outpacing your fixed income. A monthly financial calendar makes it easier to see exactly which recurring costs have grown since your last COLA.
Step 4: Recheck any budget built on last year’s benefit amount
If you built a budget around your 2026 benefit and assumed a fixed COLA percentage, revisit it once the real number is confirmed. The gap between the 3.5% estimate and the final SSA number is usually small, but even a tenth of a percentage point changes the dollar figure when you are living on a fixed income.
Fixed Income vs. Real-World Inflation
The COLA formula is based on the CPI-W index, which tracks spending patterns of urban wage earners — not retirees specifically. Retirees typically spend a larger share of their income on healthcare and housing, both of which have outpaced general inflation in recent years. That mismatch is why many retirees on Social Security report that even a “generous” COLA year does not fully cover their actual cost increases. If your household budget has already been squeezed by rising prices, a broader look at how inflation compares to your income is worth doing alongside the COLA update.
What to Do If Your Benefit Is Your Only Income
If Social Security is your primary or only source of income, treat the COLA update as an annual budget review, not just a number change:
- Recalculate your fixed monthly costs (rent, utilities, insurance, Medicare premiums) against the new deposit amount.
- Check whether any income-based assistance programs (SNAP, LIHEAP, Medicare Savings Programs) have income limits that could be affected by the increase.
- Revisit your emergency fund target — a higher benefit slightly raises the monthly amount you would need to replace if payments were ever delayed.
Why Tracking This Matters More Than the Headline Percentage
News coverage of the COLA announcement focuses on the percentage because it is easy to compare year over year. But the number that actually affects your life is the new deposit amount, minus any Medicare premium change, applied to your specific fixed costs. Keeping a simple record of your benefit amount, your Medicare premium, and your core monthly expenses lets you see your real increase — or real shortfall — instead of relying on the headline number.

Frequently Asked Questions
When will I know my exact 2027 Social Security payment amount?
The Social Security Administration announces the official COLA percentage on October 14, 2026, but your exact new benefit amount arrives in a mailed notice or in your my Social Security online account in early December 2026, ahead of your January 2027 payment. That December notice is the number to budget from, since it already reflects your Medicare Part B premium deduction.
Is the 2027 COLA estimate of 3.5% final?
No. The 3.5% to 3.6% figures are estimates from organizations like The Senior Citizens League and AARP, based on inflation data through August 2026. The Social Security Administration calculates the official COLA using the average CPI-W for July, August, and September, and announces the final number in October. The estimate can shift slightly once September’s data is included.
Will a COLA increase affect my Medicare premiums?
Indirectly. Medicare Part B premiums are set separately by the Centers for Medicare & Medicaid Services, but they typically rise in years when Social Security COLA increases, since both are influenced by healthcare cost trends. For most retirees, any Part B premium increase is deducted automatically from the Social Security payment before deposit, which is why your net increase is usually smaller than the announced COLA percentage.
Does the COLA apply to SSI and disability benefits too?
Yes. The same COLA percentage applies to Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) benefits, not just retirement benefits. SSI recipients typically see their new payment amount at the end of December, since SSI payments are issued on the first of the month.
How much should I expect my benefit to actually increase in dollars?
It depends on your current benefit amount. Multiply your current monthly benefit by 0.035 (for a 3.5% estimate) to get a rough dollar figure — for example, a $1,800 benefit would increase by about $63 a month before any Medicare premium adjustment. Use the table above to estimate your own benefit level, then confirm the exact figure once your official December notice arrives.
