How to Use This Calculator
- Enter the total number of armed personnel in the unit.
- Set days of supply — the planning period in days (typically 1–30).
- Select intensity: 0=Training, 1=Stability, 2=Offensive, 3=Sustained Combat — this multiplies the daily round requirement.
- Enter base rounds per person per day for the primary weapon system.
- Review Total rounds, Weight (lb), Ammo cans (M2A1), Pallets, and Short tons for class V supply planning.

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersPersonnel = 150, Days of supply = 3, Intensity (0-3) = 1, Base rounds/person/day = 30 = 4 input(s) provided
- Calculate Total roundsTotal rounds = round(personnelCount * roundsPerPersonPerDay * daysOfSupply)13500 = 13500
- Calculate WeightWeight = round(totalRounds * 0.03)405 = 405
- Calculate Ammo cansAmmo cans = ceil(totalRounds / 840)17 = 17
