What is the biggest cost driver?

The size of your assessment boundary, or scope. The more systems, users, and facilities that touch CUI, the more you must secure and have assessed. Narrowing scope, often with a CUI enclave, is the most effective way to control cost.

Does the DoD estimate include fixing our security gaps?

No. DoD's modeled figure covers the assessment and affirmation cycle and assumes you are already implementing the required controls. Remediation to close gaps is separate and is frequently the largest part of the total.

CMMC Assessment Cost: The Factors That Actually Move the Price

Q: How much does a CMMC Level 2 assessment cost?

There is no single answer, because cost depends on your scope and how far your environment is from the 110 requirements. As a government benchmark, DoD's Regulatory Impact Analysis published with the CMMC final rule estimated a Level 2 certification assessment for a small entity at about $101,752 over a three-year cycle, with roughly $31,234 of that attributed to the third-party assessment fee. That estimate excludes the cost of fixing gaps to become compliant, which is often the largest expense.

Nobody can hand you an accurate CMMC price without knowing your environment, and anyone who does is guessing. What we can do is show you the one official published estimate and the real levers that move your number up or down.

The short version

There is no honest single "average" CMMC cost. The one government benchmark worth knowing: DoD's own Regulatory Impact Analysis, published with the final rule, estimated a Level 2 certification assessment for a small entity at about $101,752 across a three-year cycle, including roughly $31,234 for the third-party assessment itself. Critically, that figure excludes the cost of fixing security gaps, which is usually the biggest expense. Your real number is driven by scope and how far your controls are from the target.

The one official number worth knowing

When DoD published the CMMC final rule, it included a Regulatory Impact Analysis estimating costs. For a small entity, it modeled a Level 2 certification assessment at approximately $101,752 over a three-year cycle, with about $31,234 attributed to the C3PAO assessment fee, based on an assumed 120-hour assessment by a three-person team. Treat this as a government benchmark, not a quote. DoD itself notes these are modeled figures, and it assumes you already implement the required controls. The cost of getting there is separate.

What actually moves your price

The size of your assessment boundary (scope)

Scope is the biggest lever. Every system, user, and facility that touches CUI has to meet the requirements and be assessed. A tighter, well-defined boundary means fewer systems to secure and assess.

How far your current controls are from the target

If you already implement much of NIST SP 800-171, remediation is targeted. If you are starting near zero, the gap work (not the assessment itself) is usually the largest expense.

Whether you build a CUI enclave

Isolating CUI into a smaller enclave is a common way to reduce the number of systems subject to the full set of 110 controls, which reduces both remediation and assessment effort.

Technology and tooling

Controls like multi-factor authentication, encryption, logging, and monitoring may require new tools or subscriptions, plus the staff time to run them.

Readiness support

Many contractors hire an RPO or consultant to prepare. That is a separate cost from the C3PAO assessment, because the same firm generally cannot do both for one engagement.

Whether you pass the first time

Remediation and re-testing add cost and time. Going in prepared is the cheapest path.

Why the assessment fee is often the smaller part

The assessment measures your environment. It does not fix it. If your systems are not yet aligned to the 110 requirements of NIST SP 800-171 Revision 2, the work to close those gaps, including tools, architecture changes, documentation, and staff time, is frequently larger than the assessment fee. This is exactly why preparing first, with help if you need it, protects your budget: you avoid paying an assessor to document failures you could have fixed in advance.

Claims to be skeptical of

Beware anyone quoting a single "average CMMC cost." Your number depends on your scope and your starting point, and a flat average can be off by an order of magnitude.

Beware a fixed price given before any scoping conversation. A serious provider scopes first.

Beware quotes that leave out remediation, tooling, or POA&M closeout, which can be larger than the assessment fee itself.

How to read any cost estimate (August 6, 2026)

Market pricing for readiness and assessment varies widely by provider and environment, and it changes over time. Use the DoD benchmark to sanity-check a quote, insist on a scoping conversation before any number, and confirm current requirements against official DoD and Cyber AB sources. This guide is general information, not financial or legal advice for your situation.
