supply chain Calculators
Last updated: May 2026
Reorder Point Calculator
Compute the inventory level at which to place a replenishment order, combining expected demand during lead time with a safety-stock buffer.
Economic Order Quantity Calculator
Compute the order size that minimizes the sum of annual ordering and holding costs, using the classic Wilson EOQ formula.
Inventory Turnover Calculator
Measure how many times per year a business sells and replaces its inventory, computed as cost of goods sold divided by average inventory value.
Days Sales Outstanding Calculator
Compute the average number of days it takes to collect cash from customers after a credit sale, equal to accounts receivable divided by sales times days in period.
Safety Stock Calculator
Compute the buffer inventory needed to absorb demand spikes and supplier lead-time delays, using the max-minus-average method.
Inventory Carrying Cost Calculator
Calculate the annual cost of holding inventory by multiplying average inventory value by a carrying cost rate.
Lead Time Demand Calculator
Estimate the total units expected to be consumed during the lead time of a replenishment order by multiplying average daily demand by lead time in days.
Stockout Cost Calculator
Quantify the financial damage from running out of stock by combining lost profit on unmet sales with the broader cost of disappointed customers (returns, switching, lifetime value impact).
Order Cycle Time Calculator
Calculate total order cycle time from order placement to customer delivery by summing processing, manufacturing, and shipping time.

Measure what percentage of total warehouse storage space is currently occupied by usable inventory.
ABC Analysis Calculator
Classify your inventory items into A, B, and C categories based on their share of total annual usage value.
Supplier Performance Calculator
Measure a supplier's reliability by calculating their on-time delivery rate as a percentage of all shipments received.
Order Fill Rate Calculator
Calculate the percentage of customer orders fulfilled completely from available stock in a single shipment.
Freight Cost Per Unit Calculator
Determine exactly how much it costs to ship each unit by dividing total freight spend by the number of units shipped.
Perfect Order Rate Calculator
Calculate the percentage of orders delivered on time, in full, damage-free, and with accurate documentation — all four conditions met simultaneously.
Cash-to-Cash Cycle Calculator
Measures how many days it takes a company to convert inventory investments into cash from sales.
Demand Forecast Accuracy Calculator
Calculates how closely your demand forecast matched actual sales, expressed as a percentage.
Backorder Rate Calculator
Calculates the percentage of ordered units that could not be fulfilled from available stock and were placed on backorder.
Transportation Cost Ratio Calculator
Expresses total transportation spending as a percentage of sales revenue, a key logistics efficiency metric.
VMI Savings Calculator
Estimates the annual carrying cost savings achievable by shifting to a vendor-managed inventory (VMI) program.
Inventory Turnover Ratio Calculator
Measures how many times a business sells and replaces its inventory over a period.
Safety Stock Calculator
Calculates the buffer inventory needed to prevent stockouts when demand or supplier lead times fluctuate.
Landed Cost Calculator
Computes the true total cost of an imported product by adding freight, import duties, insurance, and handling fees to the purchase price.
Supplier Scorecard Calculator
Scores suppliers on quality, delivery, cost, and service using selectable weighted formulas.
Warehouse Space Utilization Calculator
Calculates what percentage of usable warehouse cube is currently occupied by stored goods.
Freight Cost Comparison Calculator
Compare truckload (TL) vs.
Order Fulfillment Cost Calculator
Calculate the true total cost to fulfill a single customer order, covering labor, packaging, shipping, and overhead.
Supply Chain ROI Calculator
Evaluate the net present value ROI of a supply chain improvement project by discounting future savings and revenue gains.
Reorder Point Calculator
Find the exact inventory level at which you should place a new purchase order to avoid stockouts during supplier lead time.
Bullwhip Effect Calculator
Quantify how demand variance amplifies as orders move upstream through multiple supply chain tiers—the bullwhip effect.
ABC Analysis Calculator
Classify inventory items into A, B, and C categories by annual consumption value.
Supplier Performance Calculator
Score your suppliers on quality, delivery, cost, and service using weighted metrics.
Total Logistics Cost Calculator
Add up all four components of logistics cost — transportation, warehousing, inventory carrying, and handling — in one calculation.
Capacity Utilization Calculator
Measure how effectively a factory or warehouse uses its available capacity after accounting for planned downtime.
Fill Rate Calculator
Calculate your order and unit fill rates to measure how completely customer orders are being fulfilled from available stock.
ABC-XYZ Inventory Analysis Calculator
Classify inventory items by annual value (ABC) and demand variability (XYZ) to prioritize stock management.
Supplier Performance Calculator
Score and rank suppliers on quality, on-time delivery, cost competitiveness, and service using your chosen weighting scheme.
Transportation Cost Calculator
Estimate freight costs across LTL, FTL, parcel, and intermodal shipping modes based on weight, distance, and fuel surcharges.
Inventory Carrying Cost Calculator
Calculate the total annual cost of holding inventory by combining storage, insurance, opportunity cost, and obsolescence rates against your average inventory value.
Supplier Lead Time Variability Calculator
Quantify supplier lead time variability and calculate the maximum expected lead time at your chosen confidence level to size safety stock buffers accurately.
Transportation Cost Optimization Calculator
Estimates the total cost of a shipment based on distance, vehicle type, fuel price, driver rate, and weight.
Inventory Turnover Analysis Calculator
Computes your inventory turnover ratio and days sales in inventory from annual COGS and average inventory value.
Total Landed Cost Calculator
Calculates the full cost of imported goods by stacking product cost, freight, import duties, VAT/GST, and handling fees.
