Warehouse Cost Calculator: What Does Your Warehouse Really Cost You?
Warehouse costs include all direct and indirect costs of holding inventory: capital tied up in stock, employee search time, unplanned purchasing trips, and management overhead. In craft businesses these costs are often invisible because they are spread across many small line items.
This calculator aggregates four cost blocks into an annual figure: search time, procurement trips, capital costs, and owner hours.
What does the result tell you?
The total shows what your warehouse disorder costs you per year — not in materials, but in wasted time and unnecessary trips. The largest single item is usually search time, because it occurs daily and is consistently underestimated.
Assumptions such as hourly rate, trip duration, and holding cost rate can be adjusted individually under 'Adjust values'.
Cost blocks
Search time
Employees × min/day × working days × EUR/h ÷ 60
Daily recurring, often the largest single item.
Unplanned trips
Trips/week × weeks × (duration × EUR/h + vehicle cost)
Each unplanned trip costs 1–2 hours.
Capital tied up & shrinkage
Inventory value × overstock factor × holding cost rate
Tied-up capital and silent write-off risk.
Owner hours
h/week × weeks × owner EUR/h
Coordination, ordering, supplier alignment.
Example: 3 employees
- Employees3
- Search time/person/day15 min
- Hourly rate45 EUR/h
3 × 0.25 h × 250 days × 45 = 8,438 EUR
≈ 8,400 EUR/year

Once you know what search time, overstock, and special trips are costing you, the next logical question is how much of that repleno can reduce in practice.
