Days Sales Outstanding

What is Days Sales Outstanding (DSO)?

Days Sales Outstanding is the average number of days the company takes to convert its accounts receivables (credit sales) into cash and helps us determines how good a company is in collecting its dues.

When a company sells its products to another company, they sell a major share of the products on credit (sometimes the cent percent share). And then, after a certain period of time, the company collects the money from its debtors. DSO is a calculation.

Let us look at the graph above. We note that Colgate’s DSO has been decreasing continuously and is currently at 34.09 days. On the other hand, Procter and Gamble DSO has been moving up and down and is currently lower than that of Colgate at 25.15 days.


Days Sales Outstanding Formula

Here is the DSO formula below

Days Sales Outstanding Formula = Accounts ReceivablesAccounts ReceivablesAccounts receivables is the money owed to a business by clients for which the business has given services or delivered a product but has not yet collected payment. They are categorized as current assets on the balance sheet as the payments expected within a year. read more / Net Credit Sales * 365

In the above Days Sales OutstandingDays Sales OutstandingDays sales outstanding portrays the company's efficiency to recover its credit sales bills from the debtors. The number of days debtors took to make the payment is computed by multiplying the fraction of accounts receivables to net credit sales with 365 more formula, you can see that the accounts receivables are being proportioned with the net credit sales. The accounts receivables are the amount due to the debtorsDebtorsA debtor is a borrower who is liable to pay a certain sum to a credit supplier such as a bank, credit card company or goods supplier. The borrower could be an individual like a home loan seeker or a corporate body borrowing funds for business expansion. read more. And the net credit sales can be calculated as follows –

Net Credit Sales = Gross Credit Sales – Sales Returns/Allowance/Discount

And then the proportion is being multiplied by 365 days to see the overall impact in a year.

So, what the Days Sales Outstanding depicts?

It depicts how much money has already been collected and how much is yet to be received.

Understanding this will give an investor an idea of how good a company is in collecting its money due to its debtors. And we would be able to judge the efficiency of the collection as well.

The point is, days sales outstanding help us decide how long it takes for the company to collect money from its debtors, and the number of days is added to the day’s inventory outstanding. Days inventory outstandingDays Inventory OutstandingDays Inventory Outstanding refers to the financial ratio that calculates the average number of days of inventory held by the company before selling it to the customers, providing a clear picture of the cost of holding and potential reasons for the delay in the inventory more helps us understand how long it takes to transfer the raw materials into finished products. And then, from the sum, DPODPODays Payable Outstanding (DPO) is the average number of days taken by a business to settle their payable accounts. DPO basically indicates the credit terms of a business with its creditors. read more is deducted. DPO tells us how long it takes for the company to pay off its due to its creditors.

Days Sales Outstanding Examples

Here we will take two examples. In the first example, we will go through a simple DSO calculation. And in the next example, we will see how to calculate the cash conversion cycleCash Conversion CycleThe Cash Conversion Cycle (CCC) is a ratio analysis measure to evaluate the number of days or time a company converts its inventory and other inputs into cash. It considers the days inventory outstanding, days sales outstanding and days payable outstanding for more.


Company Xing had gross credit sales of $500,000 in a year. It had sales returns of $50,000. It had accounts receivables of $90,000. Find out the Days Sales Outstanding (DSO).

In this example, first, we will find out the ‘net credit sales.’

Gross credit sales are given, and we also have a sales return.

So, the net credit sales would be = ($500,000 – $50,000) = $450,000.

We also have been given accounts receivables. It is $90,000.

Now, we need to put the data into the DSO formula.

DSO Formula = Accounts Receivables / Net Credit Sales * 365

Or, Days Sales Outstanding = $90,000 / $450,000 * 365 = 1/5 * 365 = 73 days.

That means Company Xing takes 73 days to collect money from its debtors on an average.


Company Zang has the following information –

Find out Days Inventory Outstanding (DIO), Days Payable Outstanding (DPO), and Days Sales Outstanding (DSO). And then also calculate the cash conversion cycle.

This is an advanced example.

We will first calculate the three important parts of the cash conversion cycle, and then we will ascertain how many days it takes to complete the cash conversion cycle of Company Zang.

We will first look at each formula and put in the data to find out the ratio.

The formula of Days Inventory Outstanding (DIO) = Ending Inventory / Cost of Sales * 365

Putting the data into the formula, we get –

DIO = $30,000 / $300,000 * 365 = 1/10 * 365 = 36.5 days.

The formula of Days Payable Outstanding (DIO) = Accounts PayableAccounts PayableAccounts payable is the amount due by a business to its suppliers or vendors for the purchase of products or services. It is categorized as current liabilities on the balance sheet and must be satisfied within an accounting more / Cost of Sales * 365

Putting the data into the formula, we get –

DPO = $60,000 / $300,000 * 365 = 1/5 * 365 = 73 days.

DSO = Accounts Receivables / Net Credit Sales * 365

Putting the data into the Days Sales Outstanding formula, we get –

DSO = $60,000 / $360,000 * 365 = 1/6 * 365 = 60.73 days.

Now, we will look at the formula of the cash conversion cycle –

For eg:
Source: Days Sales Outstanding (

Putting the data into the formula, we get –

Cash Conversion Cycle = 60.73 days + 36.5 days – 73 days

Or, Cash Conversion Cycle = 24.23 days.

Since the company takes more time to pay off its creditors, quickly collects the money from its debtors, and translates the raw materials into finished goods in a short period of time, it is able to create a cash conversion cycle, which is just 24.23 days.

From the point of view of efficiency, it’s a great achievement because cash flow is the lifeblood of the business. And from the calculation above, it is evident that Company Zang has been doing quite well in completing the full cash conversion cycle within a short period of time.

Note: A quick note is needed to be given here. Just calculation of the cash conversion cycle isn’t enough to justify whether the company is doing well or not. Of course, completing the cash conversion cycle within a month is commendable; but we also need to compare the result with other similar companies under the same industry to get an idea about it.
