CMMC Level 2 Cost: $50,000 to $500,000 for C3PAO Certification
Level 2 is the most common and most impactful CMMC requirement. It applies to all contractors handling Controlled Unclassified Information (CUI) and requires a triennial third-party assessment by a certified C3PAO. With mandatory C3PAO certification beginning November 2026 under Phase 2, preparation cannot wait.
Phase 2 starts November 2026. All new solicitations and contracts requiring Level 2 will mandate C3PAO certification, not just self-assessment. See timeline details.
Cost by Company Size
| Company Size | First-Year Total | Per Employee |
|---|---|---|
| < 50 employees | $50,000 - $150,000 | $2,400 - $4,600 |
| 50 - 200 employees | $100,000 - $300,000 | $1,200 - $2,800 |
| 200+ employees | $200,000 - $500,000+ | $700 - $1,400 |
C3PAO Assessment Fees
The C3PAO assessment is the single largest line item for most organizations. Fees vary based on several factors:
User count
More users = more access control evidence to review, more interview subjects, more configuration samples.
Asset count
Each in-scope device needs verified configurations. 50 assets vs 500 assets changes the assessment duration dramatically.
Location count
Each physical location requires on-site evaluation. Multi-site assessments add travel costs and assessor days.
CUI complexity
Multiple CUI categories, complex data flows, and shared systems increase the assessor's workload.
SSP quality
A well-written System Security Plan with complete evidence packages speeds the assessment. Poor documentation extends it.
External service providers
Each cloud service, SaaS tool, or MSP in scope requires its own evidence chain. More providers = more review.

| Backup and Recovery | $5,000 - $30,000 | Air-gapped backups, tested recovery procedures |
The 110 Practices: 14 NIST 800-171 Domains
Level 2 requires compliance with all 110 security practices across 14 domains from NIST SP 800-171 Rev 2. Here is how the practices distribute and what each domain typically costs to implement:
| Domain | Practices | Typical Cost |
|---|---|---|
| Access Control | 22 | $8K - $60K |
| Awareness and Training | 3 | $2K - $10K |
| Audit and Accountability | 9 | $15K - $100K |
| Configuration Management | 9 | $5K - $30K |
| Identification and Authentication | 11 | $5K - $35K |
| Incident Response | 3 | $3K - $20K |
| Maintenance | 6 | $2K - $15K |
| Media Protection | 9 | $3K - $20K |
| Personnel Security | 2 | $1K - $5K |
| Physical Protection | 6 | $2K - $15K |
| Risk Assessment | 3 | $5K - $25K |
| Security Assessment | 4 | $10K - $40K |
| System and Communications Protection | 16 | $15K - $80K |
| System and Information Integrity | 7 | $5K - $30K |
Three-Year TCO for Level 2
| Year 1 | Year 2 | Year 3 | 3-Year Total | |
|---|---|---|---|---|
| < 50 employees | $50K - $150K | $30K - $60K | $35K - $70K | $115K - $280K |
| 50 - 200 employees | $100K - $300K | $50K - $100K | $60K - $120K | $210K - $520K |
| 200+ employees | $200K - $500K | $80K - $120K | $100K - $140K | $380K - $760K |
Year 3 includes pre-assessment preparation for the triennial re-certification cycle.
POA&M Considerations
A Plan of Action and Milestones (POA&M) allows you to receive a conditional certification for 180 days while closing specific gaps. However, not all findings qualify for POA&M treatment. The following are considered assessment showstoppers that cannot be deferred:
- FIPS-validated encryption not deployed for CUI at rest and in transit
- Multi-factor authentication not implemented for all privileged and remote access
- Audit logging not capturing required events across all in-scope systems
- No system security plan (SSP) or the SSP does not accurately describe the environment
- No incident response plan or capability
If your assessment results in a conditional certification with POA&M items, you must close all items within 180 days. Failure to do so voids the certification and requires a new assessment.
