If you run a small defense shop, you have heard the scary numbers and you are trying to work out whether CMMC will eat your margin or just dent it. Let's get specific to a small contractor, using the DoD's own small-entity estimates.
The Small-Business Cost Problem in One Sentence
In the DoD's estimate, Level 2 certification costs a small contractor less in raw dollars ($104,670 against $117,768 for a larger entity), but far more per employee, and that per-employee burden is what makes Level 2 feel disproportionate when you are small.
What a Small Contractor Should Actually Budget
Split your budget into two buckets: the first-year program cost and the ongoing annual cost. Conflating them hides the year-two cost.
The anchor with a named primary source is the DoD's own published figure. The CMMC Program Regulatory Impact Analysis puts the three-year Level 2 certification cost for a small entity at $104,670, of which the C3PAO assessor engagement is $31,234. The rest is your own staff time and outside service-provider support, plus affirmations: Plan and Prepare at $20,699, conducting the assessment at $45,509, reporting at $2,851, and three years of annual affirmations at $4,377.
| Small-entity Level 2 Certification (3-year) | Amount |
|---|---|
| Plan and Prepare | $20,699 |
| Conduct Assessment (your staff and outside support) | $45,509 |
| C3PAO assessor engagement | $31,234 |
| Report Results | $2,851 |
| Annual Affirmations (3-year) | $4,377 |
| Three-year total | $104,670 |

Ongoing annual cost. After certification, you carry the cost of staying compliant: monitoring, evidence upkeep, documentation refreshes, and the three-year reassessment cycle. The affirmation line above is part of that. Treat maintenance as a recurring operating expense, not a one-time capital hit.
Why Per-Employee Cost Punishes Small Contractors
Look at the table again. The conduct-of-assessment and prepare lines, the labor, together come to more than twice the assessor fee. That labor does not shrink with company size in the DoD's estimate: a small entity's non-assessor lines total $73,436 over three years, against $65,712 for a larger entity, because the small entity is assumed to buy most of its hours from an External Service Provider (RIA pages 15 and 24 to 26). You still need the same SSP, the same evidence, the same ongoing monitoring against the same 110 controls. You just have fewer people to spread the work across, so each person absorbs more of it.
That structural disadvantage is why automation matters for small contractors: agents that carry the repeatable workload leave your team the decisions.
Before you commit a dollar to a C3PAO, see your directional readiness on ten controls. The free gap check is a 10-question self-assessment, not an official SPRS score.
Run the free gap check →Three Ways Small Contractors Waste Money on CMMC
- Over-scoping the environment. If CUI touches your whole network because you never segmented it, you just put every machine inside the assessment scope. Scoping discipline shrinks what gets assessed. Our small-business cost breakdown shows how an enclave shrinks the boundary.
- Buying point tools you cannot maintain. A pile of disconnected security tools with no one to run them produces shelfware, not evidence.
- Paying to re-document what changed. A year-two cost to avoid: paying hourly rates to rebuild evidence that was not kept current.
The AaaS Path for Small Contractors
ai4cmmc.ai is built for the small contractor without a compliance department. It checks the read-only configuration of the commercial cloud and identity systems you connect against the 110 Level 2 controls, re-scanning about every seven days, and answers the rest from your own evidence. It drafts your SSP and POA&M and re-issues them with an evidence package on your tier's cycle, so year two starts from a current record. Agents do the repeatable documentation and measurement; your Affirming Official decides what goes to the assessor.
This is operational independence: a system does the repeatable documentation and measurement, so you are not renting a consultant's calendar every cycle for it. Every tier has a month-to-month option with no long-term contract. For the full line-item budget and a 90-day plan, see how much CMMC certification costs for a small business.
