Assumptions and pay data
Pay data: Armed Forces pay. Junior Rank (OR-1 to OR-3): £27,282 to £38,553, rates from 1/4/2026. Checked 30/9/2026.
- Both paths use today's pay scales, with no pay awards, and count gross pay only.
- The calculator starts you at the first point of the new band.
- Each year in the comparison moves you a year up your band before pay is worked out, so the “promoted later” path is paid £28,001 in its first year.

Guide for Junior Rank
This guide helps Junior Rank at Armed Forces compare promotion timing scenarios from Junior Rank (OR-1 to OR-3). The calculator shows gross earnings only; promotion still depends on vacancies, funding and employer policy.
Why promotion timing matters for Junior Rank

Over five or ten years the cumulative difference can be substantial, even when the step from Junior Rank (OR-1 to OR-3) to the next band looks modest year to year. This tool compares gross earnings under two promotion timings using illustrative pay from Armed Forces pay.
Typical progression for Junior Rank
Junior Rank → Senior Rank → NCO. Use the calculator on this page to see how pay changes over time.
What to compare in the calculator
Set your current band (Junior Rank (OR-1 to OR-3)), years already in band, and how far ahead to project. Choose when the first promotion happens in each scenario and the target band after promotion. Optionally add a second promotion step for longer career routes.
Real world factors
Promotion depends on vacancies, performance, funding and policy. The calculator does not model competition for posts or time to complete training. Use it for financial comparison alongside career planning conversations with your line manager or union.
