About ToolSite
A free, accurate BTZ score estimator built by current and former Air Force NCOs — grounded in AFI 36-2502 and AFPC promotion guidance.
Who We Are
BTZ Calculator was built by a team of current and former Air Force NCOs who have sat on BTZ boards, built promotion packages, and mentored Airmen through the Below the Zone process. We've watched candidates walk into boards underprepared — not because they lacked the ability, but because they didn't have a clear picture of how the scoring actually worked.
That's what this tool is for. The BTZ formula under AFI 36-2502 isn't secret, but it's also not intuitive. Most Airmen don't realize that the EPB rating multiplies their entire score, or that the board interview accounts for over 54% of the total points. We built a calculator that makes those dynamics visible before the board meets — not after.
Built for Airmen
Every feature of this calculator was designed around how the BTZ board actually scores candidates — based on AFI 36-2502 and AFPC BTZ program guidance, not approximations.
Formula Transparency
We show you exactly how each input contributes to your score — board average, EPB multiplier, fitness, decorations, and community involvement. No black boxes.
Accuracy First
Our scoring model is cross-referenced against AFI 36-2502, Air Force Personnel Center (AFPC) guidelines, and the Enlisted Promotion System (EPS) documentation. We update when AFPC publishes changes.
Our Research Process
Every scoring formula in this calculator was built from primary sources — specifically AFI 36-2502 (Airman Promotion/Demotion Programs), AFPC's official BTZ program guidance, and the Enlisted Promotion System (EPS) documentation. We don't rely on secondhand summaries or forum posts.
When AFPC publishes updated promotion guidance or changes to the BTZ board process, we review the changes and update the calculator accordingly. The lastUpdated date on every page reflects when the content was last verified against current AFPC policy.
Our blog articles are written by NCOs with firsthand experience in the BTZ selection process — either as candidates, supervisors, board members, or First Sergeants managing the board process at the unit level. We don't publish content that can't be verified against official Air Force guidance.
Important Disclaimer
BTZ Calculator is an independent, unofficial tool. It is not affiliated with, endorsed by, or operated by the United States Air Force, AFPC, or any government agency. Results are estimates based on publicly available AFI 36-2502 scoring criteria. Actual board outcomes depend on the specific panel, the competitive pool at your installation, and AFPC promotion rates by AFSC — factors this tool cannot account for.
Use this calculator as a planning tool, not as a guarantee of selection. Always verify current promotion guidance with your unit's First Sergeant or career advisor.
