What Retirees May Actually Keep in 2027 [American Impact](https://americanimpact.org/blog/author/american-impact) Oct 6, 2026, 8:00:00 AM ###### [Entitlement Programs,](https://americanimpact.org/blog/tag/entitlement-programs) [Social Security](https://americanimpact.org/blog/tag/social-security) *A new estimate points to a larger benefit increase in* ***2027****, but the official result and retirees’ net gains still depend on inflation data and Medicare costs.* ## **What to Know** - AARP projects a **3.6%** Social Security cost-of-living adjustment, or COLA, for **2027**. - BLS will release the September CPI report on **October 14, 2026**, completing the data needed for the final calculation. - Social Security uses the average CPI-W reading from **July**, **August**, and **September** to set the annual adjustment. - A **3.6%** increase would add about **$75** per month to a **$2,084** average retired-worker benefit. - CMS has not yet announced the standard Medicare Part B premium for **2027**, so no final estimate can show what retirees will keep after premiums. A projected **3.6%** Social Security COLA would be larger than the **2.8%** increase beneficiaries received in **2026**. According to[AARP](https://www.aarp.org/social-security/cola-2027-increase-estimate/), its estimate rose after August inflation data became available. That figure offers an early guide for retirees planning next year’s budgets, but it is not an official benefit increase. Final numbers will depend on September inflation data. The[Bureau of Labor Statistics](https://www.bls.gov/schedule/2026/) will release that report on **October 14, 2026**, at **8:30 a.m. Eastern Time**. Social Security can then complete its statutory calculation and announce the **2027** COLA in October. Until then, households should treat any percentage as a projection rather than a promise. ## **Why 3.6% Is Still Only an Estimate** August’s inflation report supplied only **two** of the **three** months used in the COLA calculation. AARP’s estimate reflects the CPI-W data available so far, while September’s reading can still raise or lower the final result. A[CBS News report](https://www.cbsnews.com/news/2027-social-security-cola-cpi-report/) notes that AARP previously estimated a **3.5%** increase before the August data moved its estimate to **3.6%**. Small changes matter because Social Security rounds the final adjustment to the nearest one-tenth of **1%**. BLS measures several versions of inflation. Headlines often focus on the Consumer Price Index for All Urban Consumers, or CPI-U. Social Security instead uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. BLS explains that CPI-W reflects a narrower population than CPI-U, which includes more than **90%** of the total U.S. population.   ![](https://americanimpact.org/hs-fs/hubfs/undefined-Oct-03-2026-09-47-04-7271-AM.png?width=576&height=355&name=undefined-Oct-03-2026-09-47-04-7271-AM.png) [*Inflation trends behind the COLA estimate. CBS News.*](https://www.cbsnews.com/news/2027-social-security-cola-cpi-report/) That distinction explains why a headline inflation rate does not automatically equal a retiree’s future COLA. Understanding the formula is the next step toward estimating what a projected percentage could mean for a monthly benefit. ## **How Social Security Calculates a COLA** Social Security compares the average CPI-W for **July**, **August**, and **September** with the average for those same months one year earlier. If the index rises, the agency increases benefits by that percentage, rounded to the nearest one-tenth of **1%**. If the index does not rise, beneficiaries receive no COLA. For the **2026** adjustment, the[Social Security Administration](https://www.ssa.gov/oact/cola/latestCOLA.html) compared a third-quarter CPI-W average of **317.265** with **308.729** from the prior year and calculated a **2.8%** increase. Benefits rose in January, while Supplemental Security Income payments reflected the adjustment at the end of December.![](https://americanimpact.org/hs-fs/hubfs/undefined-Oct-03-2026-09-47-05-1074-AM.png?width=687&height=494&name=undefined-Oct-03-2026-09-47-05-1074-AM.png)   [*CPI-W growth used for COLA calculations. CRFB.*](https://www.crfb.org/blogs/28-cola-highlights-benefits-cola-cap) Congress designed the formula to preserve purchasing power, not to match every household’s individual expenses. Retirees may spend more than other households on health care, prescription drugs, housing, or food. Others may have lower costs or additional income. CPI-W provides one nationwide adjustment, not a personalized budget. A formula can determine the gross benefit increase, but a household’s actual financial result depends on deductions and expenses that the COLA does not control. ## **What a Projected Increase Could Mean Each Month** AARP used a June average retired-worker benefit of about **$2,084** as an illustration. If the final **2027** COLA is **3.6%**, that example would increase by about **$75** per month, to roughly **$2,159** before Medicare premiums, taxes, or other deductions. Individual results will vary because benefits and deductions differ. Individual results will differ. Someone receiving **$1,500** per month would see an estimated increase of **$54**. A beneficiary receiving **$3,000** per month would see an estimated increase of **$108**. Both examples assume that the final COLA is **3.6%**. Medicare Part B premiums can change what a beneficiary receives in a Social Security payment. CMS set the standard **2026** Part B premium at **$202.90** per month, up **$17.90** from **$185.00** in **2025**.[CMS](https://www.cms.gov/newsroom/fact-sheets/2026-medicare-parts-b-premiums-deductibles) has not yet announced the standard Part B premium for **2027**.   | **Year** | **Monthly Premium (USD)** | | --- | --- | | 2020 | $144.6 | | 2021 | $148.50 | | 2022 | $170.10 | | 2023 | $164.90 | | 2024 | $174.70 | | 2025 | $185.00 | | 2026 | $202.90 |   [*Medicare costs can reduce a COLA gain. Nationwide.*](https://www.nationwide.com/financial-professionals/topics/health-care-cost-longevity/pages/medicare-changes-for-2026)   No responsible estimate can therefore state how much of a **2027** COLA Medicare premiums will absorb. Beneficiaries should wait for the official premium announcement, then compare their new gross benefit, Medicare deduction, prescription-drug costs, housing expenses, and other recurring bills. That household comparison turns a national percentage into a practical budget decision. ## **What Retirees Should Watch Before January** Retirees should watch for **three** announcements: the September CPI report on **October 14**, Social Security’s official COLA announcement later in October, and CMS’s **2027** Medicare premium announcement. Benefit notices will provide each recipient’s personal payment amount. Medicare participants should also review any Part D drug-plan or Medicare Advantage changes during open enrollment, because premiums, formularies, deductibles, and provider networks can change even when a Social Security benefit rises. Policymakers face a related challenge. COLAs protect beneficiaries from broad inflation, yet the CPI-W formula does not remove the pressure of health-care costs or guarantee that every retiree’s purchasing power will rise. Clear communication about gross benefits, deductions, and household expenses helps seniors make better decisions before coverage and payment changes take effect. ## **Wrap Up** AARP’s **3.6%** estimate suggests that Social Security benefits could rise by roughly **$75** per month for an average retired worker in **2027**. September CPI-W data will determine whether that estimate holds. Retirees should focus on more than the headline percentage. Net income will depend on each person’s benefit, Medicare deductions, prescription costs, and everyday expenses. Official October announcements will provide the figures households need to plan accurately for January.
