The following is the May 4, 2016 cost estimate from the Congressional Budget Office on the House Fiscal Year 2017 National Defense Authorization Act.
From the summary:
H.R. 4909 would make several changes to military retirement and health care benefits. The bill also would make changes to the national defense stockpile, reduce unobligated balances in the Department of Defense Acquisition Workforce Development Fund, and require women to register with the Selective Service. Several other provisions would change direct spending by an insignificant amount over the 2017-2026 period. On a preliminary basis, CBO estimates that in total enacting H.R. 4909 would reduce net direct spending by $206 million over the 2017-2026 period (see attached table).
The bill also would make numerous changes to the military justice system that CBO expects would increase the amount of fines and forfeitures of pay that are assessed at military courts-martial by less than $500,000 over the next 10 years. Those fines are classified as revenues. Because enacting the bill would affect direct spending and revenues, pay-as-you-go procedures apply.
