Cash Conversion Cycle Calculator
The cash conversion cycle is the single most important measure of working capital efficiency. It combines three operational metrics: how long inventory sits before being sold (DIO), how long it takes to collect after a sale (DSO), and how long the business takes to pay its suppliers (DPO). The lower the CCC, the less working capital is tied up in the operating cycle, and the less external financing the business needs to fund its operations. This calculator derives all three components from your balance sheet and income statement data, then computes the CCC and the working capital freed per day of cycle improvement.
Cash conversion cycle formula
DIO = (Avg Inventory / COGS) * 365
DSO = (Avg Accounts Receivable / Revenue) * 365
DPO = (Avg Accounts Payable / COGS) * 365
CCC = DIO + DSO - DPO
CCC benchmarks
- Amazon: negative CCC (customers pay before suppliers are paid).
- Grocery retail: 5 to 20 days.
- General manufacturing: 40 to 80 days.
- Healthcare / pharma: 70 to 120 days.
Cash conversion cycle: frequently asked questions
What is the cash conversion cycle?
The cash conversion cycle (CCC) measures the time between when a company pays for inventory and when it collects cash from selling that inventory. CCC = Days Inventory Outstanding + Days Sales Outstanding - Days Payable Outstanding. A lower or negative CCC is better.
What does a negative cash conversion cycle mean?
A negative CCC means the company collects cash from customers before it has to pay its suppliers, effectively receiving free financing from the supply chain. Amazon and many large retailers operate with negative cash conversion cycles as a structural advantage.
How do I reduce the cash conversion cycle?
Reduce CCC by: converting inventory to sales faster (reduce DIO), collecting receivables faster (reduce DSO), and negotiating longer payment terms with suppliers (increase DPO). Even small improvements in each component compound into significant working capital savings.
What is a good cash conversion cycle?
The ideal CCC depends on industry. Retail and grocery aim for 0 to 20 days. Manufacturing targets 30 to 60 days. B2B service businesses (no inventory) aim for 30 to 50 days (DSO minus DPO). Negative CCC is achievable for subscription and high-volume businesses.
How does the CCC affect financing needs?
A longer CCC means more working capital tied up in the operating cycle, requiring more external financing (credit lines, loans). Reducing CCC by 10 days for a $50M revenue business can free up $1.4M in working capital ($50M / 365 * 10).
