Frequently Asked Questions
How do I calculate safety stock?
Safety stock accounts for demand variability and supply uncertainty. Calculate based on desired service level, standard deviation of demand, and standard deviation of lead time. Common practice is 1-2 weeks of average usage for stable products, more for critical items.
What if my lead time varies?
Use your worst-case or 95th percentile lead time for reorder point calculations. Variable lead times increase safety stock requirements. Track actual lead times to establish realistic planning values.
Should I include supplier minimum order quantities?
Reorder points indicate when to order, not how much to order. If minimum order quantities exceed typical needs, you may need to adjust safety stock upwards or consider supplier consolidation to optimize economics.
How often should I review reorder points?
Review quarterly or when significant changes occur: new suppliers, product launches, seasonal demand shifts, or after supply chain disruptions. Regular reviews ensure calculations remain accurate.
What's the difference between reorder point and economic order quantity?
Reorder point tells you WHEN to order based on inventory levels. Economic order quantity (EOQ) tells you HOW MUCH to order based on minimizing total costs. Use both together for optimal inventory management.
Can I use different reorder points for different seasons?
Absolutely! Seasonal demand variations warrant different reorder points. Calculate separate values for peak and off-season periods, and implement changes in your purchasing system to match demand patterns.
