CMMC certification cost ranges from $60,000 to $275,000 in year one for most small to mid-sized defense contractors. The DoD’s official cost estimate for CMMC Level 2 triennial certification is $105,000 to $118,000, based on the 32 CFR Part 170 Final Rule analysis. Our experience helping clients through gap assessments, controls, and documentation – and what C3PAO assessors consistently report – is that the realistic number is higher once remediation work, documentation labor, and staff hours are counted.
Understanding what drives that range is the starting point for any CMMC budget. Here’s how the numbers break down.
Key Takeaways
- CMMC Level 2 certification costs most small and mid-sized defense contractors between $60,000–$275,000 in year one.
- The biggest cost variable is remediation.
- Contractors who skip a gap assessment before engaging a C3PAO may add time and cost to their initial budget.
- Managed IT services from a provider with CMMC experience can help you with documentation, in addition to having NIST SP 800-171’s 110 controls in place.

CMMC Level 1 vs. Level 2: How the Costs Compare
Level 1 covers 15 controls protecting Federal Contract Information (FCI) and is self-assessed annually. So there isn’t a C3PAO requirement. However, there are still costs associated with internal labor to maintain documentation and conduct self-assessments – typically $5,000 to $20,000 per year – depending on how much documentation support is needed.
Level 2 covers 110 controls protecting Controlled Unclassified Information (CUI). Starting with Phase 2 enforcement, a C3PAO assessment is required for all prioritized acquisitions.
The costs described throughout this article apply to Level 2.

CMMC Cost Breakdown: What You’re Actually Paying For
CMMC Level 2 certification involves several distinct cost lines. Here’s what to budget for each.
Gap Assessment: $10,000–$20,000
This is the diagnostic phase where you get a structured review of your current security posture against NIST SP 800-171’s 110 controls and 320 assessment objectives.
The range reflects the scope and provider. Organizations that skip a gap assessment and move into their audit routinely face findings they weren’t prepared to address.
So, a $10,000 gap assessment almost always pays for itself.
Remediation and Implementation: $10,000–$125,000
This is the most variable cost in CMMC work, and the hardest to estimate without a gap assessment. It spans IT infrastructure work, policy and procedure documentation, security control implementation, and System Security Plan development.
Internal Labor and Documentation: $10,000–$80,000+
This is the cost most organizations don’t really consider. CMMC Level 2 preparation conservatively requires 400 to 800 hours of internal staff time between project management, documentation, evidence collection, and assessor coordination. Valued at fully loaded labor rates, that’s money that never appears as a line item but is real cost.
C3PAO Assessment: $30,000–$50,000
For small defense contractors under 50 employees, expect $30,000 to $50,000 for a two-stage assessment (Stage 1 documentation review, Stage 2 controls testing). Larger organizations or those with a broader in-scope environment can expect to pay more.
Year 1 Total
Most small and mid-sized defense contractors will spend somewhere between $60,000–$275,000 in the first year.
Cost Table
Cost Category | 2025–2026 Data | Notes |
|---|---|---|
Year 1 Level 2 (small & medium business) | ~$60K–$275K | Depends heavily on scope and starting posture |
DoD official estimate | $105K–$118K | Assessment + affirmations only |
Gap assessment | ~$10K–$20K | Varies by scope and provider |
Remediation & implementation | ~$10K–$125K+ | This is the most variable cost |
C3PAO assessment | ~$30K–$75K | Matches DoD + industry |
Internal labor & documentation | ~$10K–$80K+ | Depends on rates + staffing model |
Level 1 cost | ~$5K– $20K+ | Most small contractors land around $10K-$15K |
Where Costs Can Easily Blow Up
1. Unplanned remediation scope.
Contractors who skip the gap assessment often discover mid-project that their findings are far more extensive than they expected. Because of that, their scope expands, timelines extend, and costs increase proportionally.
Get a formal gap assessment against NIST SP 800-171 before engaging a C3PAO. It’s the most cost-effective risk mitigation solution available to you. It tells you what you’re actually dealing with.
2. Hidden documentation hours.
The 110 NIST SP 800-171 controls need to have evidence. So your System Security Plans, policies, procedures, and audit logs all require someone’s time to create and maintain.
Building it internally is a significant and consistently underestimated labor commitment.
3. Repeat assessments.
Industry data suggests roughly 15 to 30 percent of first-time CMMC Level 2 attempts result in open Plans of Action and Milestones requiring re-testing. Each additional assessment cycle adds assessment fees (for a partial reassessment), plus any remediation costs.
Mock assessments conducted before the C3PAO engagement – working through the evidence package, practicing the interview, and closing identified gaps – are the most effective way to reduce this risk.
The Advantages of Working with a Compliance-focused MSP
Many controls are put into place quickly.
An MSP familiar with compliance frameworks should get most of NIST SP 800-171’s 110 controls in place quickly as a of its standard service.
Things like access control, endpoint security, patch management, incident response, backup and recovery, and configuration management all map directly to CMMC Level 2 requirements.
In an MSP-managed environment, a gap assessment typically finds controls that need documentation and formalization. That shifts the weight away from control implementation to evidence building. Which is great news for you because implementation is where a good chunk of the cost is. In practice, this compresses remediation cost significantly for most organizations.
They possess institutional knowledge.
An managed IT provider that has been through a C3PAO assessment itself (not one that has studied CMMC, but one that has been assessed) understands exactly what assessors ask for, what documentation format they expect, and where organizations typically accumulate findings.
For example, Teal completed its CMMC Level 2 assessment with all 110 controls satisfied and zero open Plans of Action and Milestones. That experience is what separates a consultant who can genuinely prepare you for CMMC requirements from one who is making educated guesses alongside you.
Controlling Your CMMC Costs
CMMC certification cost is determined more by your current security posture than by the assessment process itself. So, contractors who spend the least getting ready will be the ones whose IT foundation was already professionally managed, and who ran a gap assessment before engaging a C3PAO.
If your organization handles CUI under a DoD contract, understanding your cost exposure before Phase 2 enforcement timelines tighten is the most useful step you can take now.
A gap assessment against NIST SP 800-171 is the right place to start. Contact Teal CMMC team or explore our CMMC managed IT services to get one underway.
