Frequently Asked Questions
What is the warehouse interest rate?
Warehouse interest represents the cost of capital tied up in inventory. It is calculated as average inventory value times market interest rate divided by 100. High inventory ties up capital that could be invested elsewhere.
How can I reduce warehouse costs?
Optimize inventory turnover through just-in-time delivery, ABC analysis, accurate demand forecasting, and reducing slow-moving stock. Higher turnover means lower capital commitment.
What is the Storage Interest Calculator?
The warehousing cost calculator computes the capital carrying cost for goods held in stock. It shows the costs arising from holding inventory.
How does the Storage Interest Calculator work?
Enter the average inventory value (in euros), warehousing interest rate and storage period. Warehousing cost = average inventory * rate * storage days / 360. The calculator also determines the inventory turnover rate.
Key Data and Facts
Warehousing rate = market rate / 360 * average storage period. Inventory turnover = cost of goods sold / average inventory. High turnover = low warehousing costs.
Step-by-Step Guide
How to calculate die Lagerzinsen step by step: 1. Durchschnittlichen Lagerbestand determine: (Anfangsbestand + Endbestand) / 2, bewertet zum Einstandspreis. 2. Marktzins (Kalkulationszins) angeben: Oft wird der Kontokorrentzins der Bank oder ein kalkulatorischer interest rate (z. B. 5-8 %) verwendet. 3. Durchschnittliche Lagerdauer calculate: Lagerdauer = 360 / Lagerumschlagshaeufigkeit. 4. Lagerumschlagshaeufigkeit calculate: Wareneinsatz / durchschnittlicher Lagerbestand. 5. Lagerzinssatz calculate: Marktzins x durchschnittliche Lagerdauer / 360. 6. Lagerzinsen calculate: Durchschnittlicher Lagerbestand x Lagerzinssatz / 100. Beispiel: Durchschnittlicher Lagerbestand 120.000 EUR, Wareneinsatz 480.000 EUR/year, Marktzins 6 %. Lagerumschlag: 480.000 / 120.000 = 4x pro year. Durchschnittliche Lagerdauer: 360 / 4 = 90 days. Lagerzinssatz: 6 % x 90 / 360 = 1,5 %. Lagerzinsen: 120.000 x 1,5 % = 1.800 EUR/year. Massnahme: Bei Lagerumschlag von 6x: Lagerdauer 60 days, interest rate 1,0 %, interest nur 1.200 EUR -- Ersparnis 600 EUR.
Calculation Example
Lagerbestand 120.000 EUR, Wareneinsatz 480.000 EUR/year, 6 % Marktzins. Lagerumschlag: 4x. Lagerdauer: 90 days. Lagerzinssatz: 1,5 %. Lagerzinsen: 1.800 EUR/year.
