CMMC certification cost is one of the most searched questions in the defense contractor community right now — and the answers you'll find online range from $5,000 to $3 million. That range is real, but it's not helpful. The actual cost for a small defense contractor depends on where you're starting, how much CUI you handle, and how much of the work you do yourself versus hire out.
This guide breaks down every cost component with realistic numbers for small contractors — typically 10–100 employees, handling some CUI, pursuing Level 2.
The Five Cost Buckets of CMMC Compliance
1. Gap Assessment: $0 – $21,000
Before you can fix anything, you need to know where you stand. A gap assessment measures your current control implementation against the 110 NIST 800-171 requirements and tells you what's missing.
- DIY with software ($0–$150/mo): Using a tool like CMMC Map, you can run your own gap assessment in a few hours. This produces a real gap report with control-by-control status. Best for most small contractors.
- Consultant-led ($8,000–$21,000): A CMMC consultant or RPO conducts the assessment for you. Adds credibility and expertise, but expensive. Totem charges $9,200 for a readiness review; $21,200 for a full gap assessment.
2. Technology Remediation: $5,000 – $80,000+
This is where most of the real money goes. Closing security gaps often means:
- Upgrading to Microsoft 365 Business Premium or GCC High (~$22/user/mo)
- Implementing endpoint detection and response (EDR) software ($5–$15/endpoint/mo)
- Setting up a SIEM or logging solution ($500–$5,000/mo)
- Creating a CUI enclave if you don't have one ($10,000–$80,000 one-time)
- Multi-factor authentication, vulnerability scanning, backup systems
Organizations that already use Microsoft 365 and have basic security hygiene spend less here. Those starting from scratch or running on-premise infrastructure spend significantly more.
3. Documentation: $500 – $30,000
The SSP, POA&M, and 14 required policies are mandatory artifacts for Level 2. Writing them is time-intensive — for a small organization, expect 80–150 hours of effort.
- DIY with software (about $149/mo): A tool like CMMC Map generates your SSP, POA&M, and policies from your answers. You review and finalize. Realistic cost: $500–$1,800 in software fees plus your own time.
- Consultant-written ($10,000–$30,000): A consultant writes your documentation for you at $150–$300/hour. Higher quality review, but significant cost. Most small contractors don't need this.
4. Training and Awareness: $1,000 – $5,000
NIST 800-171 requires security awareness training for staff with access to CUI. Options range from self-administered training (free to low cost) to formal training packages ($1,620+ from vendors like Totem). Phishing simulation is required by some controls — budget $1,000–$2,000 if you need a vendor to run it.
5. The C3PAO Assessment: $20,000 – $60,000
This is the formal third-party assessment that results in your CMMC Level 2 certification. You can't do this yourself — it must be conducted by a CMMC Certified Third-Party Assessor Organization (C3PAO) authorized by the Cyber AB.
- Small organizations (under 50 employees, limited scope): $20,000–$35,000
- Mid-size organizations (50–200 employees): $35,000–$60,000
- Complex environments, large CUI boundary: $60,000+
Assessment costs have risen significantly since enforcement began. Budget conservatively.
Total Cost Summary: Small Contractor Scenarios
| Cost Bucket | DIY-Focused | Consultant-Heavy |
|---|---|---|
| Gap Assessment | $0–$150/mo (software) | $9,200–$21,200 |
| Technology Remediation | $5,000–$30,000 | $15,000–$80,000+ |
| Documentation (SSP/POA&M/Policies) | $500–$1,800 | $10,000–$30,000 |
| Training & Awareness | $500–$2,000 | $1,620–$5,000 |
| C3PAO Assessment | $20,000–$45,000 | $30,000–$60,000 |
| Total Range | $26,000 – $79,000 | $66,000 – $196,000+ |
The Biggest Lever: Documentation DIY vs. Consultant
The single largest cost difference in the table above — the $10,000–$30,000 spread in documentation — is entirely within your control. Consultants charge $150–$300/hour for documentation work. For a 110-control SSP plus policies, that's 80–150 hours of billable time.
A purpose-built CMMC software tool generates the same documents from your answers. The output isn't as polished as a seasoned consultant's work, but it's assessor-ready and costs $500–$1,800 total. Most small contractors are better served by generating their own documentation and using any consultant budget on pre-assessment review instead.
The contractors who spend the most on CMMC compliance are usually the ones who hired consultants to do work they could have done themselves — and then couldn't explain their own SSP when the assessor asked.

Scope creep — trying to make your entire organization compliant instead of scoping tightly to systems that actually touch CUI — is the #1 cost driver. Every additional system in scope adds remediation work, documentation requirements, and assessment time.
Starting late — beginning your compliance work 6 months before the deadline instead of 18 months before means paying a premium for C3PAO assessments, rushed consulting, and emergency technology deployment.
Skipping pre-assessment prep — contractors who walk into a C3PAO assessment without a complete, reviewed SSP routinely fail and have to pay for a re-assessment. Pre-assessment readiness is the highest-ROI spend in your CMMC budget.
