Quick answers regarding inventory KPIs and formulas.
The standard safety stock formula is: (Maximum Daily Sales × Maximum Lead Time) – (Average Daily Sales × Average Lead Time). This ensures you have enough buffer inventory to handle unexpected spikes in demand or supply chain delays.
A good inventory turnover ratio generally falls between 4 and 6 for most retail and manufacturing businesses. This indicates that a company is restocking items efficiently without overstocking. However, this varies heavily by industry.
OTIF stands for On-Time In-Full. It is a key performance indicator that measures a supplier’s ability to deliver the expected product in full at the expected time. It is calculated as (Number of OTIF Orders / Total Orders) × 100.
