The DoD's own Federal Register cost estimates put CMMC Level 2 certification for a small contractor at approximately $104,670 for the assessment cycle alone. Industry research from 2025 puts full first-year costs, including preparation, remediation, and assessment, between $138,000 and $285,000. Most organizations significantly underestimate these figures.
