Improper Payments Experience

The chart below* shows the improper payment experience for the Retirement, Survivors, and Disability Insurance (RSDI) program for fiscal years (FY) 2015 - 2017. We calculate the underpayment rate by dividing underpayment dollars by dollars paid, and we calculate the overpayment rate by dividing overpayment dollars by dollars paid. The percentages and dollar amounts presented in the table below are correct based on actual numbers used from the source data, but there may be differences in the calculated underpayment and overpayment rates due to rounding.
