Cost of Money Rates
Federal agencies are required to use interest rates computed under the criteria established by the Renegotiation Act of 1971 (P.L. 92-41). For example, the Contract Dispute Act of 1978 (P.L. 95-563) and the Prompt Payment Act (P.L. 97-177) provide for interest due on claims at a rate established by the Secretary of the Treasury pursuant to 31 U.S.C. 3902(a).
