Cooling Inflation Just Shrank Your 2027 Social Security Raise

If you’re on Social Security, the 2027 raise you were counting on just got smaller on paper.

One month ago, one closely watched forecaster was calling for a 4.7% cost-of-living adjustment next January. After Tuesday’s inflation report showed prices actually fell in June, the same analyst dropped the number to 3.7%. The Senior Citizens League, which has been running its own tally all year, is sitting at 3.8%.

Take a $2,000 average retired-worker check. A 4.7% raise would have added about $94 a month. At 3.8%, you’re looking at closer to $79. It’s not a disaster. It’s about $180 a year, gone.

What actually happened

The Bureau of Labor Statistics reported June CPI on July 14. The all-items index dropped 0.4% for the month, the biggest one-month decline since April 2020. Twelve-month inflation cooled to 3.5%. Energy prices, the thing that had been driving forecasts higher all spring, fell 5.7% in a single month. Gas at the pump did most of that work.

That matters here because the COLA isn’t set by opinion. It’s set by a formula. The Social Security Administration averages the CPI-W, the version of the index that tracks urban wage earners, over July, August, and September, and compares it to the same three months a year earlier. The percentage difference is your raise.

June’s number isn’t in that window. But it’s the last read forecasters had before the window opened. When it came in soft, the projections came in with it.

Why the July print is the one to watch

July’s CPI-W lands August 12. It’s the first of the three months that actually count. If July looks like June, the 3.8% neighborhood holds. If gas prices bounce back, or if a fresh tariff round pushes goods prices back up, the number climbs. If disinflation keeps going, it drops.

None of this is settled until the SSA’s mid-October announcement, right after the September CPI is published.

What eats into the raise

Medicare Part B does. The standard premium is deducted straight from Social Security checks, and it jumped from $185 to $202.90 in 2026, a $17.90 monthly bite. The Medicare trustees currently project the 2027 premium at about $209.50, another $6.60 a month.

For the first time since 2023, the COLA is expected to outpace the Part B hike in percentage terms. So the raise you keep is real. It’s just smaller than the headline number, as it always is.

What to do this month

You don’t need to do anything with the estimate itself. It’s an estimate. The number that hits your bank account is whatever the SSA announces in October.

Two moves are worth making now if the COLA math matters to your budget. Plan around the low end of the range: building a budget around 4.7% and getting 3.8% is a harder conversation than the reverse. And check whether you’re paying the Part B standard premium or the income-adjusted IRMAA version. If you crossed an IRMAA bracket in 2025, your 2027 premium bite is going to be bigger than $209.50, and you’ll want to know that before Medicare tells you in November.

File the rest away until October. That’s when the number gets real.
