How to Estimate Your Next Social Security COLA - Step by Step
The Social Security COLA estimator shows the projected next-year adjustment the moment the page opens - no input needed - and turns it into your own dollar figure when you type your monthly benefit. Everything runs in your browser on live CPI-W data from the US Bureau of Labor Statistics.
Step 1 - Open the page and read the headline
The big percentage at the top is the estimated COLA for next year, computed with the official formula: the July-September average of the CPI-W index, compared with the same three-month average from last year, rounded to the nearest 0.1%. A colored badge tells you which state you are looking at - an orange "projection" badge means at least one third-quarter month is not published yet, and a green "official-formula value" badge means all three months are in the data.
Step 2 - Type your monthly benefit
Enter your current gross monthly benefit in the input box - the number from your award letter or my Social Security account, before Medicare deductions. The result table updates as you type: estimated new monthly benefit, and the monthly increase in dollars, rounded down to the dime the way SSA rounds. If you leave the box empty, the table shows a clearly-labeled $2,000 example so you can still see how the output reads.
Step 3 - Check the numbers behind the estimate
Scroll to the comparison table. Each row is one CPI-W month - July, August, September - for the baseline year and the current year, with the quarter averages in the last row. A value marked "projected" is standing in for a month BLS has not released yet; every other value is the published index, so you can verify any of them against the BLS data. The line under the table shows the raw percentage change before rounding.
Step 4 - Watch the countdown
The page counts down to the official announcement, which happens the morning BLS releases September CPI data - October 14, 2026 at 8:30 a.m. Eastern for the 2027 COLA, per the BLS news-release calendar. After the announcement, confirm the official figure at ssa.gov/cola; the January payment is the first one that includes it.
Step 5 - Come back after each CPI release
CPI data lands monthly, so the projection tightens twice before the announcement: once when August data arrives, once more when September data completes the quarter. The page caches the series in your browser for a few hours; reopening it after a release date pulls the fresh numbers automatically.
Reading the result honestly
The output is the gross change only - Medicare Part B premiums, tax withholding, and the earnings test can all shift your net deposit, and the page says so under the result. For the situations where the estimate is most useful, see when a COLA estimate helps; to see how this compares with waiting for the news or the official notice, read the comparison with the alternatives.
