Subject: Changes to Agency Contributions for FERS, FERS-RAE and FERS-FRAE

Beginning in Fiscal Year 2021

At its April 2018 meeting, the Board of Actuaries of the Civil Service Retirement System 

recommended revised long-term economic assumptions and changes to the demographic 

assumptions for use in actuarial valuations of Civil Service Retirement System (CSRS) and 

Federal Employees Retirement System (FERS). These revised assumptions resulted in new 

normal cost percentages that increase agencies’ contribution rates for FERS employees, FERSRevised Annuity Employees (FERS-RAE) and FERS- Further Revised Annuity Employees 

(FERS-FRAE) beginning in October 2020. 

 

The new contribution rates will become effective with the first pay period beginning on or 

after October 1, 2020. 

The following tables summarize changes to contribution rates for FERS, FERS-RAE, and FERSFRAE:
