CMMC Certification Cost in 2026: Complete Breakdown for Defense Contractors

If you're a defense contractor wondering about CMMC certification cost, you're not alone — it's the number-one question we hear from govcon teams preparing for mandatory assessments. The Cybersecurity Maturity Model Certification (CMMC) 2.0 framework is now required for contractors handling Controlled Unclassified Information (CUI), and the costs range from $20,000 for small Level 1 self-assessments to over $500,000 for large Level 3 organizations.

What Does CMMC Certification Cost?

CMMC certification costs range from $20,000 to $100,000+ depending on your organization's size, current security posture, and target certification level. Level 1 self-assessments typically cost $5,000–$15,000, while Level 2 C3PAO assessments run $50,000–$100,000+ including remediation, consulting, and assessment fees.

This guide breaks down every cost category — assessment fees, consulting, technology investments, and ongoing maintenance — so you can budget accurately and avoid surprises.

Understanding CMMC 2.0 Certification Levels

Before diving into costs, it's essential to understand what you're certifying against. CMMC 2.0 simplified the original five-level framework into three tiers, each with different assessment requirements and cost implications.

Level 1: Foundational (17 Practices)

Level 1 covers Federal Contract Information (FCI) protection with 17 basic cybersecurity practices drawn from FAR 52.204-21. The key cost advantage: self-assessment is permitted. You don't need a third-party assessor — your company conducts the evaluation and affirms compliance annually through the Supplier Performance Risk System (SPRS).

Level 2: Advanced (110 Practices)

Level 2 is where most defense contractors land. It aligns with all 110 security requirements in NIST SP 800-171 Rev 2, covering 14 control families from Access Control to System and Information Integrity. Most Level 2 contracts require third-party assessment by a CMMC Third-Party Assessment Organization (C3PAO) accredited by the Cyber AB. For a detailed breakdown of every control, see our CMMC Level 2 requirements guide.

Level 3: Expert (110+ Practices)

Level 3 adds requirements from NIST SP 800-172 on top of Level 2. Assessment is conducted by the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC), a government entity. Level 3 is reserved for contractors supporting the most sensitive DoD programs.

CMMC Assessment Fees: What C3PAOs Charge

The direct assessment fee is the most visible cost, but it varies widely based on organization size, scope complexity, and C3PAO pricing.

Level 1 Self-Assessment

Level 2 Third-Party Assessment

Level 3 Government Assessment

Level 3 costs are harder to pin down because DIBCAC conducts the assessment (no C3PAO fee), but the preparation requirements are significantly more rigorous. Expect total costs 1.5–2x those of Level 2, primarily in technology and consulting.

The Hidden Cost Drivers Most Contractors Miss

$10,000–$50,000 per year in ongoing maintenance costs catch many contractors off guard after initial certification. Continuous monitoring tools, annual penetration testing, staff training, and policy updates are recurring expenses.

1. Gap Remediation Is the Biggest Line Item

The gap between your current security posture and CMMC requirements determines the bulk of your spending. Organizations that have been actively maintaining NIST 800-171 compliance (e.g., filing accurate SPRS scores) spend 40–60% less than those starting from zero.

Common remediation expenses include:

• Endpoint Detection and Response (EDR): $5–$15/user/month
• SIEM/log management: $10,000–$50,000/year
• Multi-factor authentication deployment: $3–$8/user/month
• Encrypted backup solutions: $5,000–$20,000/year
• Network segmentation: $10,000–$75,000 (one-time)
• CUI boundary definition and enclave setup: $15,000–$50,000

2. System Security Plan (SSP) Development

Your SSP is the cornerstone document for assessment. It maps every NIST 800-171 control to your specific implementation. A poorly written SSP is the number-one reason assessments fail or require remediation rounds.

Professional SSP development costs $15,000–$40,000 through a consultant, or significant internal staff time if done in-house. The plan must cover your entire CUI boundary — every system, application, and data flow that touches controlled information.

3. Ongoing Compliance Costs (Year Over Year)

CMMC isn't a one-time expense. After initial certification, you face annual costs:

• Continuous monitoring tools: $10,000–$40,000/year
• Annual self-assessment (Level 1) or triennial re-assessment (Level 2): $5,000–$50,000
• Staff training and awareness programs: $2,000–$10,000/year
• Incident response retainer: $5,000–$20,000/year
• POA&M tracking and remediation: $5,000–$15,000/year

4. Opportunity Cost of Non-Compliance

The most expensive "cost" is losing contract eligibility. Starting in 2025, CMMC requirements appear in DoD solicitations as go/no-go criteria. Without certification at the required level, you cannot bid — period. For contractors with $5M+ in DoD revenue, the ROI on CMMC investment is typically 5–10x within the first contract cycle.

How to Reduce Your CMMC Certification Cost

$15,000–$30,000 in potential savings is achievable by scoping your CUI boundary tightly, leveraging FedRAMP-authorized cloud services, and completing a thorough self-assessment before engaging a C3PAO.

Minimize Your CUI Boundary

The single most effective cost-reduction strategy is shrinking the scope of your assessment. Every system that touches CUI must meet all 110 Level 2 controls. By consolidating CUI handling into a defined enclave — a limited set of systems, networks, and applications — you reduce the number of controls to implement across your broader IT environment.

Cabrillo Club's private AI platform is designed around this principle: all CUI processing, proposal automation, and collaboration happen within an isolated, compliant environment. Instead of retrofitting your entire IT stack, you route CUI workflows through a purpose-built boundary.

Leverage Existing FedRAMP-Authorized Tools

If your tools are already FedRAMP-authorized, many CMMC controls are inherited from the cloud service provider's authorization. This dramatically reduces your documentation and implementation burden. See our FedRAMP collaboration tools comparison for options.

Use a Phased Approach

Don't try to achieve full compliance in one sprint. A phased approach spreads costs across budget cycles:

1. Phase 1 (Months 1–3): Gap analysis, SSP development, quick-win remediation
2. Phase 2 (Months 4–8): Technology deployment, network segmentation, training
3. Phase 3 (Months 9–12): Internal mock assessment, POA&M closure, C3PAO scheduling

Consolidate Compliance Tools

Many contractors run 8–12 separate security tools, each with its own licensing, management, and compliance documentation overhead. Consolidating onto an integrated platform reduces both direct costs and administrative burden.

Platforms like Cabrillo Club combine CUI-safe CRM, compliant AI proposal automation, and secure collaboration — all within a single CUI boundary. This consolidation approach can reduce total tool costs by 30–40% while simplifying your SSP documentation.

CMMC Cost by Industry Segment

Different types of contractors face different cost profiles based on their typical CUI exposure and existing security maturity.

Small Business Primes and Subcontractors

• Typical level: Level 1 or Level 2
• CUI scope: Limited (often just proposals and technical data)
• Total cost range: $20,000–$100,000
• Key challenge: Limited IT staff; often need external consultant support
• Cost tip: The DoD has discussed potential funding assistance for small businesses. Monitor SAM.gov for announcements.

Mid-Market Defense Contractors

• Typical level: Level 2
• CUI scope: Moderate (engineering data, logistics, program management)
• Total cost range: $100,000–$300,000
• Key challenge: Multiple CUI enclaves across business units
• Cost tip: Centralize CUI handling to reduce per-enclave assessment costs

Large Primes and Tier-1 Subcontractors

• Typical level: Level 2 or Level 3
• CUI scope: Extensive (classified-adjacent programs, CUI across all functions)
• Total cost range: $250,000–$1,000,000+
• Key challenge: Legacy systems, complex supply chains, multiple facility clearances
• Cost tip: Establish a CMMC Program Management Office (PMO) to coordinate across divisions

Choosing a C3PAO: Price vs. Value

Not all C3PAOs are created equal. The Cyber AB Marketplace lists accredited assessors, but choosing solely on price can backfire.

What to evaluate:

• Assessment methodology: Do they provide a clear assessment plan upfront?
• Remediation guidance: Some C3PAOs offer advisory services pre-assessment (though they cannot assess organizations they've consulted for)
• Industry experience: C3PAOs with defense contractor experience understand CUI boundaries
• Timeline: Assessment scheduling varies from 4 weeks to 6+ months depending on demand
• Scope negotiation: Experienced C3PAOs help you define the most efficient assessment boundary

Red flags:

• Guaranteeing certification before the assessment
• Pricing significantly below market (may indicate corner-cutting)
• No references from similar-sized organizations
• Unwillingness to share their assessment methodology

CMMC Certification Cost: Planning Your Budget

Here's a practical budgeting framework for 2026:

Step 1: Determine Your Required Level

Review your current and target contracts on SAM.gov. Look for DFARS 252.204-7021 clauses. If your contracts involve CUI, plan for Level 2.

Step 2: Conduct a Gap Assessment

Hire an experienced consultant or use internal resources to assess your current NIST 800-171 posture against all 110 controls. This determines your remediation scope.

Step 3: Build a 12-Month Budget

Using the cost ranges above, estimate your total investment. Include a 15–20% contingency for unexpected remediation items.

Step 4: Track ROI

Measure your CMMC investment against contract revenue it protects or enables. Most contractors find the math straightforward: a $5M contract justifies a $100K compliance investment many times over.

Frequently Asked Questions

How much does CMMC Level 2 certification cost for a small business?

Small businesses with fewer than 50 employees can expect to spend $50,000–$100,000 total for CMMC Level 2 certification, including gap analysis, remediation, documentation, and C3PAO assessment fees. The actual amount depends on your current security posture — organizations already maintaining NIST 800-171 compliance spend significantly less on remediation.

Is CMMC certification a one-time cost?

No. While the initial certification involves the largest investment, CMMC requires ongoing compliance costs including continuous monitoring ($10,000–$40,000/year), annual affirmations, staff training, and triennial re-assessment for Level 2. Budget approximately 20–30% of your initial certification cost annually for maintenance.

Can I self-assess for CMMC Level 2?

Some Level 2 contracts allow self-assessment rather than third-party assessment, depending on the sensitivity of the CUI involved. However, the majority of Level 2 contracts requiring CUI handling will mandate C3PAO assessment. Check the specific DFARS clauses in your contracts or anticipated solicitations.

What is the biggest cost driver in CMMC certification?

Technology remediation and gap closure typically represent 40–50% of total certification cost. Organizations that haven't been maintaining their NIST 800-171 controls face the largest remediation bills. The assessment fee itself (paid to the C3PAO) is usually only 20–30% of total cost.

Does the DoD offer financial assistance for CMMC compliance?

The DoD has acknowledged the cost burden on small businesses and has explored mechanisms through programs like Project Spectrum and the Defense Industrial Base Cybersecurity Program. Some states also offer cybersecurity grants for small defense contractors. Monitor federal and state procurement assistance programs for updates.

How long does the CMMC certification process take?

From initial gap assessment to certification, plan for 9–18 months. The timeline breaks down roughly as: gap analysis (1–2 months), remediation (4–10 months), pre-assessment preparation (1–2 months), and formal C3PAO assessment (2–4 weeks). Organizations with stronger existing security postures can compress this timeline significantly.

Should I hire a CMMC consultant or do it in-house?

This depends on your team's cybersecurity expertise. If you have a dedicated CISO or security team experienced with NIST 800-171, in-house preparation is feasible and saves $20,000–$50,000 in consulting fees. Most small and mid-size contractors benefit from at least a gap assessment by an external consultant, even if they handle remediation internally.
