5 Reasons Chained CPI Is Bad For Social Security


David Certner is the Legislative Counsel and Director of Legislative Policy for Government Affairs at

Congress and the Administration are considering, as a means of deficit reduction, a legislative change to the consumer price index - the so-called " chained CPI." This change would have a particularly negative impact on Social Security benefits - here's why:

1. Chained CPI compounds over time. 
As a result of a chained CPI, there will be a 0.3% annual cut in Social Security cost of living adjustments (COLAs). Since this compounds over time, it would end up cutting the equivalent of one full month of benefits each year from a 92-year-old beneficiary. And it's not a small cut overall - Social Security loses $112 billion over the next 10 years.

2. The greatest impact will be on the most vulnerable older Americans.
As retirees age, they have less income, fewer financial assets, and are more dependent on Social Security. Specifically, women tend to live longer than men and tend to have lower incomes, so women and poorer households are more at risk of falling into poverty with any cuts to Social Security.

3. Benefits for disabled and retired veterans would be cut.
3.2 million disabled veterans and another 2 million military retirees would see their benefits cut if chained CPI is adopted. Permanently disabled veterans who started receiving disability benefits at age 30 would see their benefits cut by more than $1,400 a year at age 45, $2,300 a year at age 55 and $3,200 a year at age 65.

4.  Chained CPI is a less accurate measure of inflation
Since retirees spend much more on medical care than working-age Americans, the current CPI calculations already underreport the rapidly increasing health care costs experienced by seniors. Moving to a chained CPI would exacerbate the gap between formula and actual costs.

5.  Social Security does not drive deficits, and should not be cut as part of a budget deal.
Social Security is a separately financed, off-budget program - it is not a driver of deficits in the rest of the budget. Any changes to Social Security should be handled separately, not as part of a budget deal that focuses on near-term savings that harm current retirees.

In an election year filled with partisanship and political fights, it’s no surprise that many Americans feel that their voices aren’t being heard or that the issues that affect their lives aren’t being addressed. But, many outstanding elected officials work hard every day to make a positive difference for their constituents.  That’s why AARP recognizes state legislators, governors, and other elected officials – from both sides of the aisle – who have stepped up and worked together to write, support, and advance common-sense policies that help older Americans remain in their homes and communities and retire with confidence. AARP is proud to announce our fifth annual bipartisan class of Capitol Caregivers, who fought this year to increase support for family caregivers and their loved ones, along with our fourth annual bipartisan class of Super Savers, who championed policies that enhance retirement security.

Caroline is a mother of two children and a preschool teacher who unexpectedly became a family caregiver for her father after he suffered a major stroke. Her father, Tom, now deceased, lost the use of his right side and his ability to speak. Multiple surgeries and rehabilitation treatments later, he was able to live at home with the help of nurses. But it was up to Caroline to provide daily care, such as overseeing appointments and handling certain nursing responsibilities, like managing his medications. “I became the person my father could rely on more than anyone in the world,” Caroline said. “I became his safe place and his best friend.” In communities across the country, family caregivers like Caroline are caring for older parents, spouses and other loved ones, helping them to remain at home – where they want to be. Their tasks are done out of love and commitment, but are not easy. That’s why AARP is fighting for family caregivers and their loved ones in every state. In 2018, AARP advanced new policies to provide more help at home, flexibility at work, training, relief and more, which will benefit over 30 million family caregivers. Here are a couple highlights:

A few months ago, I wrote a blog about the vital role that transportation options play in what we at AARP call “livable communities” – great places to live for people of all ages. Being able to get around is critical to earn a living, raise a family, contribute and stay connected to your community and enjoy life. And, having alternatives to getting behind the wheel of your own car is particularly important for older adults who want to stay in their homes and communities as they age.
