How much does CMMI certification cost?
The honest answer: it depends on your target level, size, and starting point — but the appraisal itself has a published range. Start with the estimator, then see what drives the number.
Published breakdowns put a Class A (Benchmark) appraisal at $30,000–$100,000+, with Class B at $10k–$40k and Class C at $5k–$15k. A mid-size organization targeting ML2/ML3 typically spends $50,000–$150,000+ all-in (appraisal + consulting + training); ML4/ML5 programs run $100k–$300k+. Every figure below is labeled with its source or marked as a planning estimate.
CMMI cost estimator
How this estimate is calculated (formula & assumptions)
Formula: appraisal-fee band for the target level + (consulting band for org size × maturity factor) + training band.
- Appraisal bands (planning estimates anchored on the published $30k–$100k+ Class A range): ML2 $30k–$50k; ML3 $40k–$80k; ML4 $70k–$120k; ML5 $100k–$150k.
- Consulting bands by size: 1–50: $25k–$60k; 51–250: $50k–$120k; 251–1,000: $100k–$250k; 1,000+: $200k–$450k.
- Maturity factor: ad hoc ×1.0, basic ×0.6, defined ×0.25.
- Training: $5k–$25k scaled by size. Internal staff time excluded. Re-appraisal every 3 years at ~50–70% of original appraisal cost.
Worked example (no JavaScript needed)
A 120-person software firm targeting ML3, with basic (inconsistent) processes:
- Appraisal fee (ML3 band): $40,000–$80,000
- Readiness consulting: 51–250 band ($50k–$120k) × 0.6 → $30,000–$72,000
- Training: $8,000–$15,000
- Total: roughly $78,000–$167,000, excluding internal staff time.
Bands are planning estimates derived from the published sources cited below — see the formula disclosure above for the exact math.

The table below gives planning estimates interpolated from the published ranges above — not quotes, and not measured averages.
| Organization size | Class A appraisal (ML3) | Consulting + training | Program, all in |
|---|---|---|---|
| ~30 people (small firm) | $30K–$50K | $30K–$75K | $60K–$125K |
| ~150 people (mid-size) | $40K–$80K | $58K–$135K | $100K–$215K |
| ~800 people (large) | $60K–$120K | $112K–$270K | $175K–$390K |
Estimate basis: appraisal bands anchor on the published $30k–$100k+ Class A range; consulting at size band × 0.6 maturity factor; training per size band. ML4/ML5 targets run higher — see the estimator.

What drives your price
- Target maturity level. ML4/ML5 requires a High Maturity Lead Appraiser and statistical evidence — a step-change in cost, not an increment.
- Organization size. More people means larger evidence samples and more interviews.
- Locations in scope. Multi-site appraisals multiply assessment work; a tight, well-defined organizational scope contains it.
- Starting maturity. Ad-hoc processes need full implementation help first; defined processes mostly need evidence organization.
- Partner choice. Boutique Lead Appraisers often price below large consulting firms for the same appraisal — the appraisal standard is fixed either way. Get comparable quotes.

The appraisal invoice is usually the smaller half. The bigger lines: implementation consulting, staff training, internal staff time across engineering and management, process tooling, and remediation between the gap assessment and the real thing. Budget the all-in number, not the quote.
Frequently asked
How much does a CMMI appraisal cost?
Published breakdowns put a Class A (Benchmark) appraisal at $30,000–$100,000+, depending on target level and scope. Class B appraisals run $10,000–$40,000 and Class C $5,000–$15,000. The appraisal fee is usually the smaller half — consulting, training, and staff time make up the rest.
What does a full CMMI program cost for a mid-size company?
Published planning figures put a mid-size organization targeting ML2/ML3 at roughly $50,000–$150,000+ all-in (appraisal + consulting + training + staff time). ML4/ML5 programs run $100,000–$300,000+. These are planning estimates, not quotes — use the estimator above, then get scoped quotes.
What drives CMMI cost up the most?
Target maturity level (ML4/ML5 needs a High Maturity Lead Appraiser and far more evidence), organizational size, number of locations in scope, and how defined your processes are on day one. Starting from ad-hoc processes is the single most expensive position.
Do costs drop after the first appraisal?
Yes. The rating lasts 3 years, and the processes, measurements, and evidence habits persist — re-appraisal typically runs 50–70% of the original appraisal cost. First-time implementation is the expensive part.
Can I get a fixed-fee appraisal quote?
Many partners will fix the appraisal fee once scope is defined (locations, target level, appraisal class). Consulting is more often time-and-materials. Get 2–3 scoped quotes and compare what's actually included — evidence review support and remediation re-checks vary.
Is a Class B appraisal enough for my contract?
Usually not, if the contract requires a Maturity Level rating — only a Class A (Benchmark) appraisal produces an official rating published by the CMMI Institute. Class B/C are checkpoints. Confirm what your customer actually requires before you pay.
