Cash Conversion Cycle Calculator

DIO — Days Inventory Outstanding

DIO = (Inventory / Cost of Goods Sold) × 365. It measures how many days inventory sits on the books before it is sold. A lower DIO means inventory turns over faster — the company doesn't hold stock for long. Retailers and grocers often achieve single-digit DIO; manufacturers and distributors may run 60–90 days.

Rising DIO can signal weak demand or supply chain buildup. Falling DIO (without stockouts) usually signals improving operational efficiency.

DSO — Days Sales Outstanding

DSO = (Accounts Receivable / Revenue) × 365. It measures how many days pass between a sale and when cash is collected. B2B businesses that invoice net-30 or net-60 naturally have higher DSO. Cash-and-carry retailers have near-zero DSO because customers pay at point of sale.

Increasing DSO can flag collection problems or customers stretching payment terms — a potential credit quality issue worth monitoring against revenue trends.

DPO — Days Payable Outstanding

DPO = (Accounts Payable / Cost of Goods Sold) × 365. It measures how long the company takes to pay its suppliers. A higher DPO is generally favorable — the company is using supplier credit to fund operations longer. But excessively high DPO can strain supplier relationships or signal the company is struggling to pay on time.

Large retailers and dominant platforms often negotiate extended payment terms precisely because suppliers need their shelf space or distribution reach — a competitive moat in itself.

Negative CCC: The Best-Case Scenario

When CCC is negative, the company collects from customers before it has to pay suppliers. Amazon and Costco are the canonical examples — Costco members pay annual dues upfront, inventory turns quickly, and suppliers are paid on 30-day terms. The result: supplier financing is essentially free working capital that scales with revenue.

A sustainably negative CCC is a genuine competitive advantage. It means growth is largely self-financing from an operating working capital standpoint, without the need for credit lines or equity dilution.

Retail and Consumer

Retailers range from negative CCC (warehouse clubs, fast-fashion) to 60+ days (specialty retail with seasonal inventory). Grocery chains run near-zero or negative CCC — high inventory turnover and mostly cash transactions. Apparel retailers carry seasonal risk: if inventory doesn't clear, DIO spikes and CCC deteriorates rapidly.

Manufacturing and Industrials

Manufacturing typically shows CCC of 60–120 days. Raw materials must be purchased, processed, and stored as finished goods before being sold — and customers on net-30 or net-60 terms add further delay. Capital goods manufacturers (aerospace, defense, heavy equipment) can run 90–150+ day cycles due to long production lead times and project-based invoicing.

Technology and Software

Pure software companies often show low or negative CCC — minimal inventory, subscription billing (paid upfront), and sometimes extended supplier payment terms. Hardware-heavy tech companies look more like manufacturers. The sector average masks wide dispersion: a cloud SaaS company and a server hardware manufacturer have almost nothing in common from a working capital standpoint.

Healthcare and Pharma

Pharmaceutical distributors run 30–60 day cycles, but drug manufacturers with long R&D pipelines and complex supply chains can stretch to 90+ days. Hospitals and health systems are often slow to collect (high DSO) due to insurance billing complexity, pushing their CCC above 60 days even with short inventory cycles. CCC for financial companies and REITs is not meaningful — use other metrics.
