Cash Conversion Cycle (CCC)

Definition

Cash conversion cycle is the number of days it takes a company to convert its investments in inventory and other resources into cash flows from sales. It measures the time lag between paying suppliers and collecting from customers, and a shorter cycle means faster access to cash.

Formula

CCC = Days Inventory Outstanding + Days Sales Outstanding − Days Payable Outstanding

Overview

The cash conversion cycle (CCC) combines three working capital metrics into a single number that shows how efficiently a business turns its operational investments into cash. It is calculated by adding days inventory outstanding (DIO) plus days sales outstanding (DSO) and subtracting days payable outstanding (DPO).

A negative CCC means a company collects cash from customers before it pays suppliers, effectively using other people's money to fund operations. Amazon famously operates with a negative CCC. For most businesses, however, the goal is to minimize the cycle. A CCC of 30–45 days is typical for well-run B2B companies, while SaaS companies with upfront annual billing can achieve very short or negative cycles.

Shortening the CCC improves cash flow and reduces the need for external financing. Tactics include: negotiating longer payment terms with suppliers (increasing DPO), reducing inventory levels (decreasing DIO), and collecting from customers faster through upfront billing or shorter net terms (decreasing DSO). Each day removed from the CCC frees up working capital that can be reinvested in growth.

Example

A company has DIO of 25 days, DSO of 40 days, and DPO of 30 days. CCC = 25 + 40 − 30 = 35 days, meaning it takes 35 days on average to convert investments into cash.
