Rate for Federal Water Projects| NRCS Economics

Everything but Water Resource Projects should use OMB Circular No. A-94, Discount Rates For Cost-Effectiveness, Lease Purchase, and Related Analyses for analysis involving federal funding, or the appropriate commercial discount (interest) rate for non-federal analysis.  The 2020 OMB rate is 2.0% for all non-PL-566 watershed cost and benefit analysis.
