Social Security's 2018 Raise May Not Reach Up to 70% of Its Beneficiaries

For tens of millions of Americans, Social Security provides a financial foundation that they simply couldn't live without. Data from the Social Security Administration (SSA) in 2016 finds that 62% of retired workers -- and there are more than 42 million of them receiving a monthly stipend from the SSA -- relies on their monthly payment for at least half of their income.

Social Security's 2018 raise is announced

Given how important Social Security income is for a majority of seniors, last week's inflation data release from the Bureau of Labor Statistics (BLS) bore particular importance. The BLS's September inflation announcement was the last piece of the puzzle needed to figure out what the cost-of-living adjustment (COLA) would be in the upcoming year. Think of COLA as nothing more than the "raise" that Social Security beneficiaries receive from one year to the next as a result of inflation.

Social Security's COLA is tethered to the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. The average reading of the CPI-W during the third quarter (July, August, and September) of the previous year acts as the baseline figure, while the average reading from the third quarter of the current year acts as the comparison. If the average price of the eight major spending categories tracked by the CPI-W rises, then Social Security recipients receive a raise that's commensurate with the percentage increase from the previous year, rounded to the nearest 0.1%. If prices fall year over year, benefits remain the same. Thankfully, they can never fall because of deflation.

The Oct. 13 data release from the BLS allowed us to determine that Social Security beneficiaries are on track to receive a 2% raise in 2018. Considering that the August snapshot from the SSA shows the average retired worker receives $1,371.14 a month, it means a little more than $27 extra a month in the pockets of the average beneficiary.

However, there's quite the caveat to this year's Social Security raise: Most beneficiaries may not get it.

A majority of Social Security recipients may not receive their raise

Most Social Security recipients fall into two groups. First there are those who are eligible to receive Medicare, are currently enrolled in the program, and have their monthly premiums deducted from their Social Security payout. The second category includes those who aren't enrolled in Medicare and brand-new Medicare enrollees for 2018. This group also includes those who prefer to be billed directly by Medicare for their monthly premiums as opposed to having their premiums automatically deducted from their monthly Social Security check.
