Cash Conversion Cycle Calculator
Add stock days and debtor days, then take away creditor days. Your entered values stay out of analytics.
Formula and assumptions
Cash conversion cycle = stock days + debtor days − creditor days.
- Stock days, debtor days and creditor days must use the same period.
- The cycle can be negative when you are paid before you pay your suppliers.
- It combines three averages, so treat it as a rough guide to how long cash is tied up.
- Days are shown to 2 decimal places (half up).
