RL + RQ – (MinDP x MinU)
Re-order Level + Re-order Quantity – (Minimum Delivery Period × Minimum Usage)

FORMULA:
Re-Order – (Average Delivery Period × Average Usage)

RE-ORDER LEVEL:

This is the point at which it is essential to initiate purchase requisition for fresh supplies of the materials.
FORMULA:
(MaxDP x MaxU)
Maximum Delivery Period x Maximum Usage

RE-ORDER QUANTITY:

FORMULA:
MaxS + RL – (MinU x MinDP)
