According to a 2015 report from the Commonwealth Fund, the CBO overestimated enrollee total, but still offered projections closer to reality than four other forecasters (the Office of the Actuary of the Centers for Medicare and Medicaid Services, the RAND Corporation, the Urban Institute; and the Lewin Group).

Even the CBO released its own report in November 2015 that looked at how accurate their predictions have been, as well as what factors have contributed to forecasting errors.

On average, between 1982 and 2014, the CBO overestimated two-year revenue forecasts by 1.1 percent and six-year projections by about 5.3 percent.
