The Consequences of Current Benefit Adjustments for Early and Delayed Claiming

WP#2021-3

Abstract

Workers have the option of claiming Social Security retirement benefits at any age between 62 and 70, with later claiming resulting in higher monthly benefits.  These higher monthly benefits reflect an actuarial adjustment designed to keep lifetime benefits equal, for an individual with average life expectancy, regardless of when benefits are claimed.  The actuarial adjustments, however, are decades old.  Since then, interest rates have declined; life expectancy has increased; and longevity improvements have been much greater for high earners than low earners.  This paper explores how changes in longevity and interest rates have affected the fairness of the actuarial adjustment over time and how the disparity in life expectancy affects the equity across the income distribution.  It also looks at the impact of these developments on the costs of the program and the progressivity of benefits.

The paper found that:

  • The increases in life expectancy and the decline in interest rates argue for smaller reductions for early claiming and a smaller delayed retirement credit for later claiming.
  • Specifically, the benefit at 62 should equal 77.5 percent, as opposed to 70.0 percent, of the full age-67 benefit, and the benefit at 70 should equal 119.9 percent, instead of 124.0 percent, of the full benefit.
  • The outdated actuarial adjustments are a modest moneymaker for the program – about $1.9 billion in 2018, with most of the gains coming from those claiming at 62, who are typically lower earners. Surprisingly, the correlations between earnings and life expectancy and between earnings and claiming behavior have only modest implications for both the cost and progressivity of Social Security benefits.
  • Finally, the cost and distributional effects of earnings-related life expectancy and claiming cannot be addressed through the actuarial adjustments for early and late claiming. They reflect the fact that high earners get their large benefits for a long time and low earners get their more modest benefits for a shorter time.

 
The policy implications of the findings are:

  • Increases in life expectancy and the decline in interest rates suggest smaller reductions for early claiming and a smaller delayed retirement credit for later claiming.
  • Accounting for differential mortality would involve changing benefits, and is not a problem that can be solved by tinkering with the actuarial adjustments.
