SPRS Score Estimator
Enter how many NIST SP 800-171 requirements are still open in each weighted tier. Get an illustrative SPRS score, a POA&M-eligibility read, and a ranked list of which gaps to close first, by score impact. About 10 minutes, nothing leaves your browser.
Decision-support boundary
The official SPRS score runs from -203 to +110 (DoD Assessment Methodology). This is an illustrative self-estimate, not an official SPRS submission or a C3PAO assessment result.This tool models the weighted arithmetic (110 minus 5/3/1-point subtractors) from the tier counts you enter, plus the 32 CFR 170.21 POA&M rules. It bottoms at -196, not the official -203, because a base 1/3/5 model does not reproduce the conditional partial-credit deductions (MFA 3.5.3, FIPS 3.13.11) behind the official floor. Confirm every figure with your assessor before reporting to SPRS.
Step 1 of 1 · your open requirements, live score
No sign-in for the illustrative estimate. The full CMMC readiness package, with your specific controls and evidence, is the gated next step.
Select your SSP status to start
Your estimated score appears as you enter open gaps. Blank tiers count as fully implemented. No sign-in required.
Your estimate will appear here
As you enter your open requirements you will see an estimated SPRS score, a readiness band, your POA&M-eligible and must-implement gap counts, and a ranked list of which gaps to close first, all before any commitment is requested.
Next step
The free estimate uses weighted tier counts. The full readiness package maps your specific NIST 800-171 gaps to weighted SPRS impact, POA&M eligibility, and evidence. Decision-support output, not a sales pitch.
