Cost guide

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.

CMMI cost by organization size

The table below gives planning estimates interpolated from the published ranges above — not quotes, and not measured averages.

Organization sizeClass A appraisal (ML3)Consulting + trainingProgram, 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.

The costs nobody quotes you

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.
