How much does NIST-framework work cost?
The honest answer: the NIST publications are free — you pay for implementation help and assessment. Every figure below is labeled: firm-published, published planning range, or directory estimate.
Published sources and our labeled estimates put an 800-171 readiness assessment at $15,000–$40,000, an 800-53 moderate-baseline assessment at $50,000–$150,000, and a CMMC Level 2 C3PAO assessment at $50,000–$150,000. Use the estimator for a planning band, then get 2–3 scoped quotes.
NIST program cost estimator
How this estimate is calculated (formula & assumptions)
Bands are directory estimates (September 2026) unless labeled otherwise. Base: 800-171 readiness assessment sized by headcount. Add-ons: CMMC Level 2 assessment, 800-53 moderate assessment, vCISO. Estimate = base_lo–base_hi + sum of selected add-on bands. Not a quote.
Worked example (no JavaScript needed)
Worked example (no JavaScript needed): a 90-person defense subcontractor pursuing CMMC Level 2.
- Base (51–200 people): $30,000–$60,000
- Add CMMC Level 2 C3PAO assessment: +$50,000–$150,000
- Planning band: $80,000–$210,000 for assessment work, before remediation and internal staff time.
Your estimate is a starting point. Bands are labeled estimates (see the 2026 pricing report). A scoped quote is what a firm actually charges you — get 2–3 and compare.

| Organization size | Assessment | Implementation | First year, all in |
|---|---|---|---|
| 1–50 people | $15,000–$30,000 | $40,000–$100,000 | $60,000–$150,000 |
| 51–200 people | $30,000–$60,000 | $50,000–$150,000 | $80,000–$210,000 |
| 201–1,000 people | $60,000–$120,000 | $100,000–$300,000 | $160,000–$400,000 |
| 1,000+ people | $100,000–$200,000 | $200,000–$500,000+ | $300,000–$800,000+ |

- NIST — the publications themselves (nist.gov)
CSF 2.0, SP 800-53, and SP 800-171 are free downloads. There is no NIST certification and no NIST fee — you pay for implementation and assessment, never for the publication. - NIST SP 800-171 Rev. 3 (2024)
The current revision of the CUI-protection requirements for nonfederal systems — 110 requirements in the prior revision, restructured in Rev. 3. - FedRAMP — about the authorization process (fedramp.gov)
FedRAMP authorization requires a 3PAO assessment against the 800-53-based baseline plus PMO review — the assessment is only part of the total cost. - Directory estimates (September 2026)

Cost questions
What does an 800-171 readiness assessment cost?
Our labeled estimates put it at $15,000–40,000 depending on CUI footprint and starting posture — see the pricing report for provenance on every row.
What does a CMMC Level 2 assessment cost?
Labeled estimate: $50,000–$150,000 for the authorized C3PAO assessment itself — readiness work and remediation are separate.
Are the NIST publications free?
Yes — CSF 2.0, SP 800-53, and SP 800-171 are free downloads. You pay for implementation help and assessment, never for the publication.
Do costs drop after the first assessment?
Typically yes — the SSP build and first assessment are one-time; reassessment and continuous monitoring cost a fraction.
How accurate are the estimator bands?
They are planning bands from labeled estimates (September 2026), not quotes. Real fees depend on scope, sector, and starting posture — get 2–3 scoped quotes and compare.
