What this calculator does

DSO estimates the average number of days it takes to collect payment after a sale on credit.

Formula and method

DSO = (average receivables ÷ credit sales) × days in period; Turnover = credit sales ÷ receivables

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Average accounts receivable: 50000 (any currency)
  • Credit sales for the period: 365000 (any currency)
  • Days in period: 365

Results

  • Days sales outstanding: 50 days
  • Receivables turnover: 7.3 ×

How to read the results

Compare DSO with your payment terms; a DSO well above terms suggests collection problems.

Assumptions and limitations

  • Use credit sales only if you can separate them from cash sales.

Financial results are estimates based on the inputs and assumptions shown. They are not financial advice; confirm figures with your lender, provider or a qualified adviser before making decisions.

Questions

Is lower DSO better?

Generally yes — cash arrives sooner — though very strict terms can cost sales.
