What Is the Cash Conversion Cycle?

The Cash Conversion Cycle (CCC) measures how many days it takes a company to convert its operational investments into cash flows from sales. It's the definitive metric for working capital efficiency. The formula: CCC = DIO + DSO − DPO.

Pre-filled with DIO=45, DSO=38, DPO=30 days → CCC = 53 days. For a $1M/year company, this means ~$145,000 is continuously tied up in the operating cycle.

The Three Components

Days Inventory Outstanding (DIO) = (Average Inventory ÷ COGS) × 365. How long inventory sits before being sold. Grocery: 15 days. Manufacturer: 60–80 days.

Days Sales Outstanding (DSO) = (Accounts Receivable ÷ Net Sales) × 365. How fast customers pay. Target: under 30 days. Above 60 = collection problems.

Days Payable Outstanding (DPO) = (Accounts Payable ÷ COGS) × 365. How long you take to pay suppliers. Higher is better — Amazon's DPO exceeds 90 days.

Negative CCC: The Holy Grail

A negative CCC means the company collects customer cash before paying suppliers — an operational funding engine. Amazon, Costco, and McDonald's all run negative CCCs. Reducing your CCC by 10 days frees ~$27,400 per $1M in annual revenue. Multiply across a $100M business: that's $2.74M in freed cash — available for growth without additional financing.

Strategies to Improve CCC

Reduce DIO: adopt just-in-time inventory and improve demand forecasting. Reduce DSO: offer 2/10 net 30 early payment discounts and automate collections. Increase DPO: negotiate extended terms with suppliers and leverage supply chain finance platforms.
