How the calculation works

packages = ceil(required × (1 + reserve) ÷ package length)

Calculate each color or dye lot separately. Adding all colors together can undercount packages because each color must be rounded up independently. Leftover after reserve is a planning number, not measured inventory.

Worked example

840 yd with 10% reserve needs 924 yd. Two 500 yd cones cover that, leaving 76 yd beyond the reserved requirement.
