What Is the Cash Conversion Cycle?
The cash conversion cycle measures how long, in days, a company’s cash is tied up in operations before it comes back as cash from customers. It tracks the journey from paying suppliers for inventory, through selling that inventory, to collecting from customers. A shorter cycle means cash returns faster and less working capital is locked up; a longer cycle means more cash is tied up funding day-to-day operations. It is one of the clearest measures of how efficiently a business manages working capital.
How to Calculate the Cash Conversion Cycle
The cycle combines three components, each measured in days:
Cash Conversion Cycle = DIO + DSO – DPO
where DIO is days inventory outstanding (how long inventory is held), DSO is days sales outstanding (how long customers take to pay), and DPO is days payable outstanding (how long the company takes to pay suppliers).
Worked example:
- Days inventory outstanding: 60
- Days sales outstanding: 45
- Days payable outstanding: 30
- Cash conversion cycle: 60 + 45 – 30 = 75 days
The Cash Conversion Cycle in Power BI (DAX)
Each component is its own measure built from inventory, receivables, and payables. Replace them with the ones in your model:
Cash Conversion Cycle = [DIO] + [DSO] - [DPO]Why the Cash Conversion Cycle Matters
The cycle shows how much cash a business needs to fund its operations and how quickly that cash recycles. A company can be profitable on paper yet strained for cash if its cycle is long, with money stuck in unsold inventory and uncollected invoices. Shortening the cycle, by turning inventory faster, collecting sooner, or paying suppliers later, frees up cash without adding a dollar of revenue, which is why finance teams watch it closely.
How to Improve the Cash Conversion Cycle
Each component offers a lever. Reducing days inventory outstanding means holding less stock or turning it faster. Reducing days sales outstanding means collecting from customers sooner. Increasing days payable outstanding means taking longer to pay suppliers, within the terms agreed. The three have to be balanced against the business relationships involved, but together they determine how much working capital the cycle consumes.
Reporting the Cash Conversion Cycle From Your ERP Data
The cycle draws on inventory, receivables, and payables data that usually live in different ERP modules. Calculating it consistently means pulling those together with matching periods and definitions. A governed data foundation brings the components onto one model so the cycle and its parts are consistent and traceable. QuickLaunch ships pre-built models for JD Edwards, Vista, NetSuite, and OneStream that surface the data behind working-capital metrics.
Frequently Asked Questions
How is the cash conversion cycle calculated?
Add days inventory outstanding and days sales outstanding, then subtract days payable outstanding. A company with 60, 45, and 30 days respectively has a 75-day cash conversion cycle.
What is a good cash conversion cycle?
Shorter is generally better, and some businesses even run a negative cycle by collecting from customers before paying suppliers. The right level depends on the industry, and the trend over time matters most.
Why does the cash conversion cycle matter?
Because it shows how long cash is tied up in operations. A long cycle can leave a profitable company short of cash, so shortening it frees up working capital without needing more revenue.
