Thirty days on 365,000 of credit sales
Enter 30,000 of accounts receivable and 365,000 of annual credit sales. Keep 365 days. That is 30,000 ÷ 365,000 × 365, which is 30 days. Receivables turn 12.17 times in the year.
Accounts receivable: 25% lower
Change accounts receivable to 22,500 while keeping the other example values the same.
Accounts receivable: 25% higher
Change accounts receivable to 37,500 while keeping the other example values the same.

Quick answer
What does the Days sales outstanding calculate?
How many days of credit sales sit in accounts receivable? This calculator uses accounts receivable, annual credit sales, and days in the period to estimate days of credit sales still unpaid immediately in your browser.
With the values currently entered, the result is 30 days — days sales outstanding. It also shows receivables turnover, credit sales per day, and accounts receivable.
How to use the Days sales outstanding
- Replace the example values with your own numbers.
- Review the result and supporting figures as they update automatically.
- Check the formula and assumptions before using the estimate for a decision.
Inputs used
- Accounts receivable
- Annual credit sales
- Days in the period — entered in days
Days sales outstanding formula
DSO = accounts receivable ÷ annual credit sales × days in the period. Receivables turnover = annual credit sales ÷ accounts receivable.
Assumptions
- The SBA glossary defines Days Receivable as accounts receivable divided by annual sales on credit, times 365.
- Use credit sales only. Cash-at-sale revenue does not sit in receivables, so it should stay out of this sales figure.

Practical guide
Days sales outstanding example and edge cases
Days sales outstanding is how long credit sales sit in receivables. The SBA glossary calls this Days Receivable: accounts receivable divided by annual sales on credit, times 365.
Example: Thirty days on 365,000 of credit sales
Enter 30,000 of accounts receivable and 365,000 of annual credit sales. Keep 365 days. That is 30,000 ÷ 365,000 × 365, which is 30 days. Receivables turn 12.17 times in the year.

Calculated result30 daysdays sales outstanding
Thirty days means a month of credit sales is still unpaid. If you need the late-fee on one overdue invoice, open the invoice late fee calculator.
Example results use the default display profile. The calculator above follows your selected country and units.
How to read the result
- Read the day count first. Then check receivables turnover. A falling day count usually means cash arrives sooner.
- Use credit sales only. A cash sale never sits in receivables, so mixing it in makes DSO look better than the book.
Edge cases worth checking
Most customers pay on the card at sale
Leave those receipts out of credit sales. DSO is a receivables measure. Card-at-sale volume belongs on the payment processor calculator.
One large invoice is 90 days old
The average can hide that invoice. Age the overdue balance on its own, then run DSO on the rest if you want a cleaner typical day count.
What changes the result most
Accounts receivable
Use a current amount for accounts receivable. Include fees or recurring costs that belong in the same figure.
Annual credit sales
Use a current amount for annual credit sales. Include fees or recurring costs that belong in the same figure.
Days in the period
Keep days in the period on the same time basis as the other inputs. Monthly and annual values are easy to mix up.

Common mistakes
Check accounts receivable
The SBA glossary defines Days Receivable as accounts receivable divided by annual sales on credit, times 365. Make sure this matches the number you enter.
Keep days in the period consistent
Use credit sales only. Cash-at-sale revenue does not sit in receivables, so it should stay out of this sales figure. Use the same units and time period throughout the calculation.
Do not rely on one days sales outstanding scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
