MEMORANDUM FOR THE
HEADS OF DEPARTMENTS AND AGENCIES
Franklin D. Raines /s/
1998 Discount Rates for OMB Circular No. A-94
On October 29, 1992,
OMB issued a revision to OMB Circular No. A-94, "Guidelines and
Discount Rates for Benefit-Cost Analysis of Federal Programs." The
revision established new discount rate guidelines for use in benefit-cost
and other types of economic analysis.
The revised Circular
specifies certain discount rates that will be updated annually when
the interest rate and inflation assumptions in the budget are changed.
These discount rates are found in Appendix C of the revised Circular.
The attachment to this memorandum is an update of Appendix C. It
provides discount rates that will be in effect for the period February
1998 through January 1999.
The rates presented
in Appendix C do not apply to regulatory analysis or benefit-cost
analysis of public investment. They are to be used for lease-purchase
and cost-effectiveness analysis, as specified in the Circular.
OMB Circular No. A-94
Revised October 29, 1992
Effective Dates. This appendix is updated annually around the time of the President's budget submission to Congress. This version of the appendix is valid through the end of January, 1999. Copies of the updated appendix and the Circular can be obtained from the OMB Publications Office (202-395-7332) or in an electronic form through the OMB home page on the world-wide WEB, /OMB. Updates of this appendix are also available upon request from OMB's Office of Economic Policy (202-395-3381), as is a table of past years' rates.
Nominal Discount Rates. Nominal interest rates based on the economic assumptions from the budget are presented below. These nominal rates are to be used for discounting nominal flows, which are often encountered in lease-purchase analysis.
Real Discount Rates. Real interest rates based on the economic assumptions from the budget are presented below. These real rates are to be used for discounting real (constant-dollar) flows, as is often required in cost-effectiveness analysis.
Analyses of programs with terms different from those presented above may use a linear interpolation. For example, a four-year project can be evaluated with a rate equal to the average of the three-year and five-year rates. Programs with durations longer than 30 years may use the 30-year interest rate.
