How is Days Sales Outstanding (DSO) calculated and what does it indicate?

Intermediate

Answer

DSO measures the average days to collect receivables: (Accounts Receivable / Total Credit Sales) x number of days in the period. A rising DSO signals slower collections, looser credit, or customer distress; a falling DSO indicates faster cash conversion. It's a core AR efficiency and working-capital metric.
DSO = (AR / Credit Sales) x Days
  = (300,000 / 1,800,000) x 90 = 15 days for the quarter.
Real-world example A jump in DSO from 35 to 48 days prompts a review that finds a major customer stretching payments.
