How to calculate the DSO?
The DSO, or average payment period, is an indicator that requires particular vigilance on the part of companies. The higher the DSO, the more the company's cash flow is put at risk. Minimizing the DSO is one of the priorities of an accounting department. Find out how to calculate a DSO and secure your cash flow.
What is DSO? Definition
DSO (Average DSO – Daily Sales Outstanding) is a key indicator of a company’s cash management performance. It measures the number of days it takes to collect payments due from customers after the date the invoice is issued. In other words, calculating DSO means calculating the average duration of your company’s customer loans.

The DSO provides important accounting information about sales that have been invoiced but are still pending collection.
Calculated in number of days, it is sometimes referred to by the acronym NJC (Number of days of customer credits).
What are the elements of the DSO calculation?
The calculation of DSO is an essential indicator to integrate into your accounting to monitor the financial health of your company.
There are two ways to calculate your DSO.
1) Calculate your DSO by the accounting method
Calculating your DSO using the accounting method involves two steps:
- Establish the ratio of your total accounts receivable (including VAT) to your sales (including VAT) over a given period (i.e., accounts receivable including VAT ÷ sales including VAT).
- Multiply this ratio by the number of days in the specified period.
Example to understand:
Here is the calculation of the DSO of a company with an outstanding customer amounting to 20 000 € for a turnover of 45 000 € including VAT over a period of 3 months (90 days):
(20 000 € ÷ 45 000 €) x 90 d = 40 days
This result indicates that on average, in this company, customers take 40 days to pay the amounts due.
This method of calculation is simple and allows us to differentiate between two types of DSO:
- The DSO of invoices not yet due: that which concerns invoices whose due date has not yet passed.
- The DSO of overdue invoices: that which concerns late payments by customers, i.e. beyond the contractual deadline.
However, it has the disadvantage of not taking into account seasonality or significant variations in sales.
2) Calculate your DSO using the countback method
This DSO calculation formula provides a more accurate view of your customers’ payment times. It shows you the real time of payment of your customers, taking into account the fluctuations of your turnover related, for example, to the seasonality. It is a question of deducting from the amount of the outstanding customers, the turnover including VAT of each month then, in parallel, to add the number of days of the corresponding months, the whole until exhaustion of the outstanding.
Example to understand:
For the month of January, your outstanding receivables amount to €40,000 including VAT.
⇨ January (31 days): Your sales including VAT are €25,000. 40 000 € – 25 000 € = 15 000 €. There are 15,000 € of outstanding customers.
⇨ February (28 days): Your sales including VAT amount to €20,000. 20 000 € – 15 000 € = 5 000 €. There is still €5,000 in outstanding receivables.
⇨ March: Your turnover including VAT is 12 000 €. You divide the outstanding balance by the month’s sales including tax, then multiply the result by the number of days in the month: (5,000 ÷ 12,000) x 31 = 12.9. The outstanding customer balance will be exhausted on March 13.
⇨ Total DSO calculation: 31 days + 28 days + 13 days = 72 days.
The average payment term for your customers is 72 days.
Although more complex, this formula allows you to accurately calculate the DSO for your entire customer base, a group of customers or a single customer. Thus, you will be able to use this method to have a more detailed vision of your customer base and define an action plan that is better adapted to your customer segmentation in order to manage it effectively.
Regardless of the approach you choose to calculate your DSO, the calculation elements remain the same: sales, outstanding receivables and the number of days in the study period.
Importance of DSO for your business
Le DSO est un indicateur de la santé financière de votre entreprise. Il donne des informations sur la rapidité et l’efficacité de vos process de relance et de recouvrement de créances. Si votre DSO est élevé, cela indique que les délais de paiement par vos clients sont longs.
On the other hand, if your DSO is low, it means that the invoices issued are collected quickly. The faster your customers pay their invoices, the lower your working capital requirements. This means that you have sufficient financial resources to cover the ongoing costs of your business. Correctly calculating your DSO is therefore essential to maintain a cash flow that is adapted to your company’s operating needs.
