Inventory Turnover Calculator
Measures how many times your inventory is sold and replaced over a period, helping you identify slow-moving stock and optimize purchasing.
How to Calculate Inventory Turnover Calculator
The formula to calculate this metric is straightforward.
Inventory Turnover = Cost of Goods Sold (COGS) / Average Inventory Value (where Average Inventory = (Beginning Inventory + Ending Inventory) / 2)
A Real-World Example
Scenario: Your auto electric parts store records a Cost of Goods Sold (COGS) of $120,000 over a year. Your starting inventory value was $25,000 and your ending inventory was $15,000.
Average Inventory: ($25,000 + $15,000) / 2 = $20,000
Inventory Turnover: $120,000 / $20,000 = 6 times per year
Why Inventory Turnover Calculator Matters for Your Business
- Indicates how efficiently your capital is tied up in physical products sitting on warehouse shelves.
- A low turnover score highlights overstocking or stagnant items that incur storage fees and risk obsolescence.
- A high turnover rate signals strong sales execution but requires strict supply chain monitoring to prevent stockouts.
Frequently Asked Questions
What is a healthy inventory turnover ratio?
For standard retail and e-commerce setups, a ratio between 4 and 6 is a balanced benchmark. High-volume consumer goods can exceed 10, while specialty industrial parts may hover around 2 or 3.
Should I use total sales revenue or COGS to calculate turnover?
Always use Cost of Goods Sold (COGS). Sales revenue includes your retail markup, which artificially inflates your turnover calculation compared to the actual cost value of the stock.
How do I safely increase my inventory turnover?
Liquidate slow-moving SKU variants with targeted bundle promotions, optimize your purchase order frequencies, and use highly accurate sales forecasting tools.
