The projected next-year Social Security COLA loads automatically from the latest CPI-W data. Type your current monthly benefit to see your estimated new amount - the number is computed in your browser and never sent anywhere. The comparison table shows exactly which third-quarter index values drive the figure, and the countdown tracks the official announcement.
Social Security COLA Estimator
This page estimates the next Social Security cost-of-living adjustment (COLA) by running the official formula on the latest CPI-W inflation data, fetched live from the US Bureau of Labor Statistics. Type your current monthly benefit and it shows the projected new amount and the dollar increase - the math happens on your device, and the amount you type is never transmitted.
How the estimate is built
Social Security ties each January's benefit increase to one specific measurement: the average CPI-W index for July, August, and September, compared with the same three-month average from the last year a COLA was determined. The percentage increase, rounded to the nearest 0.1%, becomes the COLA; a negative result means a 0% adjustment, never a cut. This estimator fetches the monthly CPI-W series and applies exactly that arithmetic, and the comparison table on the page shows every index value it used, so you can check each number against the published data.
Until the September index is published, the estimate is a projection: the months that exist are used as-is, and the latest published value stands in for the missing ones. The result panel labels that state clearly and switches to the official-formula value the moment all three third-quarter months are in the data.
When the official number arrives
The Social Security Administration announces each year's COLA on the morning the Bureau of Labor Statistics releases September CPI data - for the 2027 adjustment that release is scheduled for October 14, 2026 at 8:30 a.m. Eastern, per the BLS news-release calendar. The tool counts down to that date and points to ssa.gov/cola for the announced figure. Beneficiaries see the new amount in the payment that arrives in January.
Recent adjustments for context
| Benefit year | COLA | Announced |
|---|---|---|
| 2022 | 5.9% | October 2021 |
| 2023 | 8.7% | October 2022 |
| 2024 | 3.2% | October 2023 |
| 2025 | 2.5% | October 2024 |
| 2026 | 2.8% | October 2025 |
Two adjustments in that span outran the decade's typical 2-3% range because of the 2021-2022 inflation surge. The history is a useful sanity check: if the live projection above sits far outside the recent band, read the comparison table to see which month moved it.
What the estimate does and does not cover
The output is the gross benefit change only. Your net deposit can differ because Medicare Part B premiums are usually deducted from the payment and premium changes are announced separately in the fall; tax withholding and the retirement earnings test can also shift the final figure. After a year with a 0% COLA, SSA measures from the last year an adjustment was determined - a wrinkle this simple estimator does not model. Treat every number here as an estimate to plan with, and the ssa.gov announcement as the only official figure.
Frequently Asked Questions
How accurate is the projection before September data is published?
The estimate uses every third-quarter month that BLS has already published and lets the latest value stand in for the missing ones, so late in the quarter it is usually within a couple of tenths of a percentage point of the final number. One surprising month can still move it - that is why the panel labels the figure a projection until all three months are in, then switches to the official-formula value.
When is the official COLA announced?
The Social Security Administration announces it the morning the Bureau of Labor Statistics releases September CPI data. For the 2027 COLA that release is scheduled for October 14, 2026 at 8:30 a.m. Eastern, per the BLS news-release calendar; the official figure is posted at ssa.gov/cola.
Is my benefit amount uploaded anywhere?
No. The amount you type is used for arithmetic in this browser tab and is never transmitted. The only network request the page makes is to the official US-government BLS API to fetch public CPI-W index values - your input is not part of that request.
Why might my actual deposit change differ from the COLA percentage?
The COLA raises the gross benefit. Most beneficiaries have the Medicare Part B premium deducted from the payment, and that premium is set separately each fall - a premium increase absorbs part of the raise. Tax withholding and the earnings test for people working before full retirement age can also change the net amount.
What happens if inflation is negative?
The COLA is 0% and benefits stay where they are - the law never reduces the benefit through this formula. It has happened: 2010, 2011, and 2016 were 0% years. After a 0% year, the next COLA is measured from the last year an adjustment was actually determined.
Which inflation index does Social Security use?
The CPI-W - the Consumer Price Index for Urban Wage Earners and Clerical Workers - not the more widely quoted CPI-U. The two usually move together but are not identical, which is why a COLA can differ from the inflation number in the news. This page fetches the CPI-W series (BLS series CWUR0000SA0) directly.
