The operating cycle is also known as the cash conversion cycle. In the context of a manufacturer the operating cycle has been described as the amount of time that it takes for a manufacturer's cash to be converted into products plus the time it takes for those products to be sold and turned back into cash. In other words, the manufacturer's operating cycle involves:

  • paying for the raw materials needed in its products

  • paying for the labor and overhead costs needed to convert the raw materials into products

  • holding the finished products in inventory until they are sold

  • waiting for the customers' cash payments for the products that have been sold


Some calculate the operating cycle to be the sum of:

The above sum is sometimes reduced by the number of days in the credit terms of the accounts payable.

The operating cycle has importance in classifying current assets and current liabilities. While most manufacturers have operating cycles of several months, a few industries require very long processing times. This could result in an operating cycle that is longer than one year. To accommodate those industries, the accountants' definitions of current assets and current liabilities include the following phrase: ...within one year or within the operating cycle, whichever is longer.
