How This Calculation Works
Prevents stockouts by calculating the minimum inventory level that triggers a purchase order.
💡 Realistic Indian E-Commerce Example
Selling 20 units/day with 15 days supplier lead time and 50 units safety stock: ROP = (20 × 15) + 50 = 350 units. Reorder when stock hits 350!
