USAF promotion planning

USAF BTZ Calculator

Estimate your Senior Airman Below-the-Zone board window, BTZ sew-on date, regular SrA promotion date, and package preparation timeline.

Enter dates in MM/DD/YYYY format. The calculator uses a common estimate: regular SrA timing from TIS/TIG thresholds, then BTZ sew-on roughly 6 months earlier. Unit board schedules and local supplements can change the exact dates.

What This BTZ Calculator Estimates

This USAF BTZ calculator uses Date Entered Air Force and A1C Date of Rank to estimate regular Senior Airman timing, a possible Below-the-Zone sew-on date, an approximate BTZ board window, and a package preparation start date.

BTZ Board vs Sew-on Date

The BTZ board date is when an Airman may be considered by a unit or wing board. The sew-on date is when the Airman would actually wear Senior Airman if selected. These are not the same date, and local board calendars can shift the estimate.

4-Year vs 6-Year Enlistment

Four-year and six-year Airmen may reach early rank milestones differently, so the calculator includes a contract-length selector for context. The most important inputs for the estimate are still the official Date Entered Air Force and A1C Date of Rank.

BTZ Package Planning Checklist

  • Verify dates. Confirm Date Entered Air Force and A1C Date of Rank in official personnel systems.
  • Ask early. Talk with your supervisor, CSS, and leadership well before the estimated board window.
  • Check local rules. Local supplements and board schedules can affect package due dates.
  • Prepare evidence. Keep awards, EPR/EPB notes, education, volunteer work, and duty performance records organized.

What is Senior Airman Below-the-Zone?+

Senior Airman Below-the-Zone is a competitive early promotion opportunity for eligible Airman First Class members to sew on SrA earlier than the normal timeline.

When is my BTZ board?+

This calculator estimates a board window before the projected BTZ sew-on date. Exact board months can vary by unit, wing, MPF process, and local supplement.
