With third-party certification paused and every small contractor watching costs, the most common question we hear is some version of: "What can I use for the SPRS self-assessment that's free, or close to it?" Fair question, honest answer: you can get to a legitimate score without spending a dollar. Here's every genuinely free path, what each one gives you, and the one place where free stops being enough.
The Official (and Genuinely Free) Foundation
Three government documents underpin everything else on this list — every workbook and every app, ours included, is derived from them:
- NIST SP 800-171A — breaks each of the 110 controls into the specific assessment objectives an assessor verifies. If you want to know what "met" actually means for a control, this is the source.
- The DoD Assessment Methodology (v1.2.1) — the scoring bible: every control's point value, the 110-to-−203 scale, and the rules for the two controls that allow partial credit.
- The DoD Level 2 Assessment Guide — the Department of War's own guidance for how Level 2 assessments are conducted.
Strengths: authoritative, complete, free forever. Weakness: they're reference PDFs. They don't track your progress, do arithmetic, remember anything, or output a document. Working from them directly is like doing your taxes from the Internal Revenue Code — possible, correct, and slow.
Community Workbooks and Spreadsheets
A tier up in usability: free Excel workbooks maintained by the CMMC practitioner community — gap assessment spreadsheets with a row per control, built-in SPRS scoring math, inventory tabs, and sometimes SSP section outlines. The better ones are genuinely good, and for a contractor who lives in Excel they're a real option for reaching a first score.
Their limits show up predictably: no plain-English translation (you're still interpreting control language yourself), no evidence attached to claims, version chaos once two people edit it, and no path from "row says met" to the SSP paragraph that proves it. We've written up exactly where spreadsheets break down — the short version is that they fail at documentation time, which is also when the stakes arrive.
Free Software: CMMC Map's Self-Assessment Tier
Full disclosure, this is our product — so here is precisely what's free and what isn't. Free, forever, no credit card: the complete self-assessment. All 110 controls translated into plain English with the assessor's objectives alongside, a guided scoping wizard, your live SPRS score recalculating as you answer, and a gap list ranked by point value. Your answers are saved and stay yours; there's no trial clock.
What's not free: the paperwork. Generating the SSP, POA&M, and 14 policies from your answers — plus the built-in AI guide — is $149/month, cancel anytime. We price it that way deliberately: the assessment is the part everyone should be able to do honestly for nothing; the documentation is the part that used to require a consultant.
The Comparison, Honestly
| Resource | Scoring math | Plain English | Progress saved | Documents out | Cost |
|---|---|---|---|---|---|
| NIST 800-171A + DoD guides | Manual | No | No | No | Free |
| Community Excel workbooks | Built-in | Rarely | In the file | Outlines at best | Free |
| CMMC Map — assessment tier | Automatic, live | Yes, all 110 | Yes, in your account | Paid tier ($149/mo) | Free |
| Enterprise GRC platforms | Automatic | Varies | Yes | Yes | $500–$2,000/mo |
| Consultant-led assessment | Done for you | Verbal | Their files | Yes | $5K–$65K |
How to Choose
- You know 800-171 cold and love Excel: a community workbook plus the DoD methodology will get you to a defensible score for free. Budget real time for interpretation and documentation later.
- You want to be walked through it: use free software with the plain-English layer built in — that's the tier of CMMC Map that costs nothing, and the score it produces is just as real.
- You need the paperwork too: this is where every free path converges on the same wall. Whether you exit to a $149/month generator, a template pack, or a consultant depends on budget — but exit deliberately, before a prime asks for your SSP, not after.
Start with the free tier that stays free
