what will be the cola for soc sec in 2027

The best current estimate for the 2027 Social Security COLA is around 4.7% , though it is still a forecast and could change before the official announcement in October 2026.

What the forecasts say

• One recent estimate from independent analyst Mary Johnson puts the 2027 COLA at at least 4.7%.

• A separate senior advocacy forecast is lower, at 3.8%.

• Earlier in 2026, some projections were closer to 2.5% , showing how much these estimates can move as inflation data changes.

What to watch

The Social Security Administration typically announces the official COLA in October , using third-quarter inflation data to set the final number. So the 2027 figure is not locked in yet, and the final amount could land above or below current estimates depending on inflation over the next few months.

Quick take

If you want a single number to use right now, 4.7% is the latest headline estimate. A more cautious range based on current public forecasts would be roughly 3.8% to 4.7%.
