How the Inventory Turnover Calculator works

Turnover shows how efficiently cash moves through inventory. High turnover means less storage cost and faster compounding of profits.

  • Turnover = COGS ÷ Average inventory value
  • Days to sell = Period days ÷ Turnover

Example

5 turns a year, 73 days per turn.

Cost of goods sold in the period: 60000Average inventory value (at cost): 12000Period length (days): 365
