The good news is at this point is inflation is low and trending lower.

The bad news is that the CPI-W which is used to calculate the Social Security COLA is trending lower so that as of now there would be no 2020 COLA.

The average CPI-W for July, August, September 2018 was 246.352. The average for October, November and December 2018 CPI-W only 245.919.
