Days Sales Outstanding Ratio

Days Sales Outstanding Ratio =

Total AR

Net Credit Sales

x Number of days


The days sales outstanding ratio measures the number of days a company takes to convert its sales into cash.

The DSO ratio is important to business owners and managers because it represents the days a business holds debt on its books, which can impact cash flow.

Note: expanded calculation

Current accounts receivables balance, dividing it by your credit sales revenue during the measured period, then multiplying that number by the number of days in the measured period.

We don’t include cash sales in our calculation since they don’t affect the accounts receivable or the time taken to recover dues.


M&M Company made around $300,000 in credit sales and $200,000 in accounts receivables. Its monthly DSO is

(Total AR/Net Credit Sales) x (Number of days) = (200,000/300,000) x 30 = 20 days

M&M Company has recovered its dues in 20 days, which means its DSO is 20 days. That’s good because a DSO below 45 days implies prompt-paying customers and stable cash flow.


In general, a DSO value below 45 days is considered good.

It shows that a company will have cash for operations and won’t have to write off accounts receivable as bad debts.
