Open toolOne Study decision-preparation calculator
Estimate inventory carrying cost, turnover pressure, and multi-year impact.
Estimate capital, storage, insurance, shrinkage, obsolescence, turnover pressure, and multi-year carrying cost before an inventory decision.
Calculator
Start with a simple inventory carrying-cost estimate.
Use this quick form for a simple carrying-cost rate, then use the hub below for capital cost, storage, insurance, shrinkage, obsolescence, turnover, multi-year projections, scenarios, and exports.
Inventory Carrying Cost Hub
Break holding cost into capital, storage, risk, turnover, and cash pressure.
Use this deeper section for inventory planning, supplier quantity review, MOQ decisions, warehouse pressure, and multi-year carrying cost. It starts blank and keeps calculations on this page only.
Reading the result
Make the cost of waiting visible before adding stock.
This estimate helps you review how much capital, storage, insurance, handling, spoilage, shrinkage, and slow movement may be costing the business before buying more inventory.
Before you act
Item age, financing, shrinkage, and storage terms require current records.
It does not replace item-level demand review, warehouse terms, spoilage testing, financing review, supplier lead-time planning, or professional inventory advice. Use it to document assumptions and spot pressure points.
FAQ
Questions this tool helps frame.
What is inventory carrying cost?
It is a planning estimate for the cost of holding inventory, often reviewed as a rate against inventory value.
What is a healthy carrying cost?
It depends on the product and industry, but many teams use this calculator to notice when holding cost climbs above a target percentage of inventory value.
Why does turnover matter?
Slow turnover keeps cash tied up and can increase storage, obsolescence, and financing pressure.
Why does carrying cost matter before sourcing?
A low unit cost can still create pressure if inventory is expensive to hold or slow to move.
How does this connect to Source4Me and Scaffold?
Source4Me supports supplier and quantity review, while Scaffold supports product records, status, and inventory context.
Working notes
Keep the formula with the assumptions.
- Carrying Cost = Inventory Value * Carrying Cost RateMultiply inventory value by a carrying rate for the quick estimate, then use the hub to break carrying cost into capital, storage, insurance, admin, shrinkage, obsolescence, and turnover assumptions.
- Update the result when the record changesSupplier terms, sales, stock, costs, timing, and channel deductions can change the result materially.
