The operating cycle and the cash conversion cycle

The cash conversion cycle counts the days between paying suppliers and collecting cash from customers: the shorter it is, the less financing the business needs.

In short

  • The operating cycle runs from buying materials, through production and sale, to collecting cash. Cash rarely moves at the same moment as the activity.
  • Three balances track the timing gaps: accounts receivable (cash still to come from customers), inventory (goods not yet sold) and accounts payable (cash still owed to suppliers).
  • Their average lives are days sales outstanding (DSO), days of inventory on hand (DOH) and days payable outstanding (DPO).
  • Cash conversion cycle = DOH + DSO − DPO. It is the gap between cash going out to suppliers and cash coming in from customers.
  • A short, or even negative, cycle is ideal. A cycle that is longer than peers' or lengthening over time is a warning sign.
