The Mueller investigation resulted in charges against 34 individuals and 3 companies, 8 guilty pleas, and a conviction at trial. Furthermore, Mueller declined to offer an opinion about possible obstruction of justice by Trump, citing a Justice Department guideline that prohibits the federal indictment of a sitting president. However, Attorney General William Barr pointed to ten episodes of potential obstruction by Trump.

Regarding the cost of the investigation, a cost–benefit analysis shows a net benefit for the government, with far more income than expenses. By December 2018, the investigation had cost approximately $32 million but gained approximately $48 million. More than half of the cost of the investigation was for personnel compensation and benefits. The gains were accrued primarily by uncovering unpaid taxes by targets in the investigation, seizing assets, and collecting fines.
