The Strange Reason Social Security's 2020 COLA Could Be Higher Than Expected

When it comes to Social Security, there's perhaps no figure more closely monitored by its 63 million-plus current beneficiaries than the annual cost-of-living adjustment, or COLA.

Think of COLA as the "raise" passed along to beneficiaries that's designed to allow them to keep up with inflation (i.e., the rising cost of goods and services). Each year, during the second week of October, the Bureau of Labor Statistics (BLS) releases its September inflation report, providing the final puzzle piece for the Social Security Administration to calculate what sort of raise, or COLA, beneficiaries will be receiving in the coming year.

Here's how to calculate COLA on your own

Although this might sound a bit complicated, anyone can calculate Social Security's COLA, and I promise you it doesn't take an advanced degree in calculus to do so.

Since 1975, Social Security's COLA has been tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The CPI-W has eight major spending categories, but dozens upon dozens of subcategories, each with their own various weightings. When the BLS reports inflation data during the second week of each month for the preceding month, it also reports an aggregate CPI-W reading that can be used by anyone to determine COLA.

Here's the interesting aspect of the COLA calculation: Only months in the third quarter count. This means the CPI-W readings for July, August, and September will be used to calculate COLA for the upcoming year, with the other nine months not factoring into the calculation at all.

In order to calculate COLA, you simply need the average CPI-W reading from the third quarter of the current year (add up July's, August's, and September's CPI-W reading, then divide by three), and the average reading from the third quarter of the previous year. If the current year reading is higher, beneficiaries will receive a raise commensurate with the percentage increase, and rounded to the nearest 0.1%. As I said, you don't need an advanced math degree to calculate Social Security's COLA on your own.

Social Security's 2020 COLA could come in way ahead of estimates for a surprising reason

So, what might the 2020 COLA hold in store for beneficiaries? Keeping in mind that we're still a few weeks from even entering July, the first month that actually counts toward the COLA calculation, there are two published COLA estimates.

Mary Johnson, senior policy analyst at The Senior Citizens League (TSCL), has forecast a 1.7% COLA for 2020, which doesn't sound like much, but would actually be one of the largest increases over the past decade. Considering that the average retired worker was bringing home $1,468.39 a month as of April 2019, a 1.7% COLA would increase their benefit check by roughly $25 a month, or $300 a year.
