Safety Stock & Reorder Point Calculator

Daily demand and lead time based safety stock and reorder point.

Average daily demand [units/day]Standard deviation of daily demand [units/day]Lead time [days]Target service level [%]

Safety stock ≈ Z × σ_LT, where σ_LT = σ_daily × √(lead time). ROP ≈ average demand × lead time + safety stock.

EOQ & Inventory Cost Calculator

Economic Order Quantity with annual ordering and holding cost breakdown.

Annual demand [units/year]Order cost per orderHolding cost per unit per yearUnit purchase cost (optional)

EOQ = √(2DS / H). Annual total cost ≈ ordering cost + holding cost + purchase cost.

Intermediate

Landed Cost Calculator

Estimate total landed cost per unit including freight, insurance, duties and import fees.

Unit product cost [per unit]Quantity [units]International freight costInsurance costCustoms duty rate [% of customs value]Other import fees (handling, broker, docs)Inland freight / last mile

Simplified model: customs value ≈ product value + international freight + insurance. Duties, fees and inland freight are added on top to get total landed cost.

Pallet / Container Space Optimizer

Estimate how many cartons fit into a pallet or container based on dimensions.

Pallet / container length [mm]Pallet / container width [mm]Usable height [mm]Carton length [mm]Carton width [mm]Carton height [mm]

Uses simple block stacking, checks two orientations per layer (L×W and W×L) and full layers in height.

ABC / XYZ Classification Tool

Paste items as:
SKU; annual consumption value; coefficient of variation
One item per line (semicolon or comma separated).

ABC thresholds (by cumulative value): A ≤ 80%, B ≤ 95%, C > 95%.
XYZ based on coefficient of variation (CV): X ≤ 0.5, Y ≤ 1.0, Z > 1.0.

Transportation Mode & Cost Optimizer

Compare basic cost and transit time by mode. If you leave rates or speeds empty, typical defaults are used.

Distance [km]Shipment weight [tons]

Cost per ton-km (optional). Defaults: Truck 0.08, Rail 0.05, Sea 0.02, Air 0.50.

Truck cost [per ton-km]Rail cost [per ton-km]Sea cost [per ton-km]Air cost [per ton-km]

Average speed [km/h] (optional). Defaults: Truck 60, Rail 70, Sea 30, Air 750.

Truck speed [km/h]Rail speed [km/h]Sea speed [km/h]Air speed [km/h]

Simplified model for strategic comparison. Does not include handling times, port dwell, customs delays, etc.
