CMMC Certification Cost at a Glance
CMMC certification costs most defense contractors between $20,000 and $90,000 for the readiness engagement, plus a separate C3PAO assessment fee at Level 2. A 5–50 employee contractor typically starts at $20,000; a 51–200 employee scope runs around $55,000; a 201–500 employee or multi-site environment reaches $90,000. The size of your CUI environment drives the number more than your headcount does.
| Tier | Employees | Avantcert engagement | C3PAO fee | Max duration |
|---|---|---|---|---|
| Startup | 5–50 | from $20,000 | Separate | 120 days |
| Mid-Market | 51–200 | around $55,000 | Separate | 120 days |
| Large Enterprise | 201–500 | up to $90,000 | Separate | 120 days |
These are Avantcert ranges, already discounted 30–50% below typical market rates, and they are a starting point for a scoping conversation rather than a fixed quote. Get your own figure below.
What You're Actually Paying For
Four line items, and only one of them goes to your consultant. Contractors who budget for the consulting fee alone are the ones who get surprised.
1. The C3PAO assessment fee
Paid directly to your assessor, never to your consultant, because an organization is not permitted to both prepare and assess the same client. This is the line you cannot negotiate away, and at Level 2 on a prioritized contract it is unavoidable. Budget it separately from everything below.
2. Readiness and remediation consulting
Scoping, the NIST SP 800-171 gap assessment, the SSP and POA&M, evidence collection and assessment support. This is the Avantcert engagement quoted in the table above.
3. Technical remediation
The line nobody budgets. Multi-factor authentication, FIPS-validated encryption, logging and SIEM, endpoint controls, and often a re-architecture of where CUI actually sits. If your environment is far from the 110 controls, this can exceed the consulting fee — which is exactly why the gap assessment comes early.
4. Internal staff time
Your people answering evidence requests, sitting interviews, and changing how they work. It never appears on an invoice and it is never zero.
Cost by CMMC Level
Your contract sets your level, and the level sets the shape of the bill.
| Level | Controls | Assessment | What drives the cost |
|---|---|---|---|
| Level 1 | 17 practices | Annual self-assessment | Lowest cost. Mostly scoping — confirming you hold FCI and not CUI |
| Level 2 | 110 (NIST SP 800-171) | C3PAO on prioritized contracts | Where nearly all cost sits: remediation, SSP, evidence, plus the C3PAO fee |
| Level 3 | 110 + NIST SP 800-172 | Government-led (DIBCAC) | Highest. Enhanced controls on top of a clean Level 2 baseline |
Most contractors handling CUI are looking at Level 2. Read the full breakdown of what each level requires on our CMMC certification overview.
Cost by Company Size
Startup (5–50 employees), from $20,000. Usually a single-site environment with a small CUI footprint. The work is dominated by standing up controls that were never formalized rather than by scale.
Mid-Market (51–200 employees), around $55,000. The most common shape of DIB contractor. Multiple systems touch CUI, there is real remediation to do, and enclave design starts paying for itself immediately.
Large Enterprise (201–500 employees), up to $90,000. Multi-site or complex scope, several business units, and a supply chain with its own flow-down obligations under DFARS 252.204-7021.
Headcount is a proxy, not the driver. A 40-person engineering firm with CUI spread across every laptop can cost more to certify than a 300-person contractor with one hardened enclave.

CMMC Level 2 certification lasts three years, so the sticker price is not the whole number. Across a full cycle you should budget for the initial readiness engagement and C3PAO assessment in year one, annual affirmations in years two and three, continuous monitoring and evidence upkeep throughout, and reassessment at the end of year three.
The reassessment is cheaper than the first pass for contractors who kept their evidence current, and materially more expensive for those who let it lapse and effectively start again. Ongoing upkeep is the cheapest insurance in the programme.
Is CMMC Cost Allowable Under DFARS?
Generally yes — costs of implementing and assessing CMMC are usually treated as allowable indirect costs where they are reasonable, allocable, and not specifically excluded under FAR Part 31. That makes CMMC materially cheaper in practice than the invoice suggests.
How you actually recover them depends on your contract type and your accounting structure, so confirm the treatment with a DCAA-experienced accountant before you build a budget on it. We are consultants, not your accountants, and this is a question worth asking properly.
How to Reduce the Cost Without Shrinking Your Eligibility
Design a CUI enclave. The single biggest lever available. Put controlled data in one tightly scoped environment instead of letting it spread across your whole network, and you reduce the controls in scope, the remediation bill, and the assessment itself. This is stage one of our engagement precisely because it pays for itself.
Assess before you remediate. Contractors who buy tools first and scope second routinely pay for controls that were never in scope.
Close high-weighted controls early. A limited number of lower-weighted controls can sit on a POA&M at assessment time, but high-weighted ones like multi-factor authentication generally cannot. Discovering that late means rescheduling a C3PAO, which is the most expensive delay available.
Do not confuse cheap with scoped. A quote far below the ranges on this page usually means the assessment boundary has not been established yet, and the number will move.
CMMC Cost FAQs
How much does CMMC certification cost?
Avantcert CMMC engagements run from $20,000 for a 5–50 employee contractor, around $55,000 for a 51–200 employee scope, up to $90,000 for a 201–500 employee or multi-site environment. The C3PAO assessment fee is paid separately to your assessor. Scope, not headcount, is the biggest single driver.
How much does CMMC Level 2 cost?
Level 2 is where nearly all the cost sits, because it requires all 110 NIST SP 800-171 controls and, on prioritized contracts, a C3PAO assessment. A Level 2 readiness engagement covers scoping, gap assessment, SSP and POA&M, remediation and assessment support; the C3PAO fee is additional and paid directly to the assessor.
Is the C3PAO assessment fee included in consulting costs?
No. The C3PAO is an independent assessor and you pay them directly. A consultant is not permitted to assess the client it prepared, so the two fees always come from two different organizations. Any quote that bundles them is worth questioning.
Is CMMC cost allowable under DFARS?
Costs of implementing and assessing CMMC are generally treated as allowable indirect costs when they are reasonable, allocable and not specifically excluded under FAR Part 31. How you recover them depends on your contract type and accounting structure, so confirm the treatment with your DCAA-experienced accountant before you budget on it.
How can I reduce my CMMC cost?
Shrink the assessment boundary. A dedicated CUI enclave, where controlled data lives in one tightly scoped environment rather than across your whole network, is the single largest cost lever available, and it reduces both the readiness effort and the assessment itself.
How long does CMMC certification take?
Avantcert scopes CMMC engagements to a 120-day maximum and most finish sooner. C3PAO scheduling, not the consulting work, is currently the longest pole for many contractors.
What are the CMMC levels and which one do I need?
Level 1 covers Federal Contract Information and is an annual self-assessment against 17 practices. Level 2 covers Controlled Unclassified Information and requires all 110 NIST SP 800-171 controls, with a C3PAO assessment on prioritized contracts. Level 3 adds NIST SP 800-172 and a government-led assessment. Your contract sets the level.
