Inventory Turnover & Stock Reorder Studio

Optimize warehouse holding costs and prevent stockouts. Calculate inventory turnover ratio, days sales in inventory (DSI), reorder point thresholds, and audit multiple product SKUs.

Annual Sales & Stock Levels

Cost of Goods Sold (Annual COGS)

Beginning Inventory ($)

Ending Inventory ($)

Inventory Turnover Ratio

7.00x / year

Stock is completely cleared and replenished 7 times a year

Average Inventory on Hand: $50,000.00

Days Sales of Inventory (DSI): 52.1 Days

Stock Velocity Assessment: Healthy & Fast Moving

💡 Why DSI matters: Days Sales in Inventory tells you how many days cash sits locked inside your warehouse before generating revenue. Lower DSI means faster cash turnover.

Lead Time & Daily Sales

Average Daily Unit Sales

Supplier Lead Time (Days to deliver order)

Safety Stock (Buffer for demand spikes)

Reorder Point Threshold

450 Units

Trigger a new purchase order immediately when stock drops to this level

Lead Time Demand: 350 Units

Safety Stock Buffer: 100 Units

Stockout Risk: Protected (approx. 4 days surge runway)

💡 Reorder Point Formula: ROP = (Lead Time × Daily Usage) + Safety Stock.

Ordering & Holding Costs

Annual Demand (Units sold per year)

Fixed Order Cost ($ per order / shipment)

Holding Cost ($ per unit per year for storage)

Ideal Order Batch Size (EOQ)

500 Units

Minimizes total warehousing storage and ordering freight fees

Number of Orders Per Year: 20 orders / yr

Order Frequency: Every 18.25 days

Minimized Combined Annual Cost: $2,000.00 / yr

💡 The Ford W. Harris EOQ Formula: EOQ = √((2 × Demand × Order Cost) / Holding Cost).
