Inventory tools hub
Inventory management calculators by category
Instead of one long list, tools are grouped into clear categories: replenishment policies, buffers and service levels, portfolio analysis, and performance metrics. Pick a group and then the tool you need.
Who are these tools for?
- Warehouse and inventory managers who need practical rules.
- Operations teams that want fewer emergencies and rush orders.
- E-commerce and retail businesses that manage stock across multiple locations.
- Founders and finance leaders who want a clearer picture of how much cash sits in inventory.
What can you do with them?
- Set consistent reorder rules for key SKUs.
- Quantify safety stock instead of guessing “extra”.
- Prioritize items that matter most using ABC classification.
- Monitor turnover and holding cost to support cash-flow decisions.
Replenishment & order policies
Tools that help you decide how much to order and how often, so you move away from gut-feel ordering.
EOQ Calculator
Find the economic order quantity that minimizes total ordering and holding cost for a single item.
EPQ Calculator
Size production lots to balance setup cost and holding cost when you produce and consume at the same time.
Reorder Point Calculator
Work out when you should place the next order based on demand during lead time.
Buffers, safety stock & service levels
Quantify how much protection you need against demand and lead-time variability instead of guessing.
Lead Time Demand Calculator
Estimate demand during lead time so you can combine it with safety stock and reorder point rules.
Safety Stock Calculator
Translate service-level targets and demand variability into the buffer stock you need.
Fill Rate Calculator
Measure how much demand you actually fulfill from stock versus how much is backordered.
Inventory portfolio & prioritization
Split your SKUs into buckets so you can give more attention to items that really matter.
ABC Classification
Classify items into A/B/C groups using value or volume so you can focus on the SKUs that drive results.
Performance, turnover & cash
Understand how fast your stock moves and how much cash is tied up in inventory.
Inventory Turnover Calculator
Track how fast you convert inventory into sales using COGS and average inventory.
Average Inventory Calculator
Compute average inventory over a period so you can plug it into EOQ, turnover, and cash-flow analysis.
Inventory Holding Cost Calculator
Translate inventory value and holding rate into a clear cost number for financial decisions.
