Day Sales Outstanding (DSO) Calculator

SchoolMyKids presents the Day Sales Outstanding (DSO) Calculator under our Business Planning Calculators. This tool is designed to help students and beginners understand how efficiently a business collects payments from its customers, an essential part of managing cash flow and financial health. 

What is a Day Sales Outstanding (DSO) Calculator? 

A Days Sales Outstanding (DSO) Calculator determines the average number of days it takes a company to receive payment after completing a credit sale. DSO is an important financial indicator that helps assess how efficiently a business converts its accounts receivable into cash. A lower DSO indicates that the company is collecting payments more quickly, which typically benefits its cash flow. 

What is Days Sales Outstanding?

Days sales outstanding (DSO) is the average number of days a company takes to collect receivables (payment) after the completion of a sale.

Let’s say the DSO of a company is 45 days, which means the company has recovered its dues in 45 days.

Understanding Key Terms 

• Day Sales Outstanding (DSO): DSO reflects the average time in days it takes a company to collect payment after making a credit sale. This metric is a crucial measure of how effectively a business manages its accounts receivable. For example, a DSO of 30 days indicates that, on average, customers settle their invoices 30 days after making a purchase. 

• Accounts Receivable: Accounts receivable is the amount of money that customers owe to a company for goods or services that have been provided on credit. This appears as a current asset on the company's balance sheet. When customers buy products on credit, they create accounts receivable until they pay the bill. 

• Beginning Accounts Receivable: This is the total amount of money customers owe to the company at the start of the accounting period (usually at the beginning of the year). It represents all unpaid invoices and credit sales from previous periods that are still outstanding. 

• Ending Accounts Receivable: This represents the total amount of money customers owe to the company at the end of the accounting period. It includes all unpaid invoices and credit sales that remain uncollected by the period's end. 

• Annual Sales: Annual sales represent the total revenue generated by the company from selling goods or services during a full year. This includes both cash sales and credit sales. For DSO calculation, we typically use credit sales, but if that data isn't available, total sales can be used as an approximation. 

• Average Accounts Receivable: This is calculated by adding the beginning and ending accounts receivable and dividing by 2.

How to Use the DSO Calculator? 

Step 1: Select Your Currency 

Choose the appropriate currency from the dropdown menu (Dollar, Rupee, Pounds, or Euro). 

Step 2: Enter Beginning Accounts Receivable 

Input the accounts receivable balance at the start of your analysis period. This information is typically found on the company's balance sheet at the beginning of the accounting year.

Step 3: Enter Ending Accounts Receivable 

Input the accounts receivable balance at the end of your analysis period. This is usually found on the most recent balance sheet. The difference between beginning and ending accounts receivable helps show how the company's collection performance changed over time. 

Step 4: Enter Annual Sales 

Input the total sales for the year. This figure should represent the full annual revenue from the company's income statement. If you have access to credit sales only, use that figure for more accuracy, but total sales will work as an approximation.

Understanding Your Results 

• Average Receivables: This is the average amount customers owe you during the year. It shows the typical outstanding balance you’re waiting to collect. 

• DSO (365 days): This indicates the average number of days it takes to receive payment following a sale. A lower DSO means faster collections and healthier cash flow. A higher DSO may mean customers are taking longer to pay, which could lead to cash shortages. 

How Do I Calculate DSO? 

The DSO Formula: 

Days Sales Outstanding (DSO) = (Accounts Receivable / Net Credit Sales) x Number of days

How do you calculate days sales outstanding DSO?

You can calculate DSO of a measured period by taking the current Accounts Receivables, dividing it by the Sales Revenue for the given period and then multiplying the result by the Number of Days in the given period.

Example 

• Beginning Accounts Receivable: ₹40,000 

• End Accounts Receivable: ₹60,000 

• Annual Sales: ₹300,000 

Step 1: Calculate Average Receivables 

Average Receivables = (₹40,000+₹60,000) ÷ 2 = ₹50,000 

Step 2: Calculate DSO 

DSO = (₹50,000 ÷ ₹300,000) × 365 = 0.1667×365 = 60.8 days 

Interpretation: 

It takes about 61 days, on average, for the business to collect payment after a sale. 

Common FAQs 

What is considered a good DSO?

A good DSO varies by industry, but generally, 30-45 days is considered excellent, 45-60 days is good, and anything over 60 days may indicate collection issues. Retail businesses often have very low DSO (under 10 days) due to cash sales, while B2B companies typically range from 30-60 days. The key is to compare your DSO with industry benchmarks and your company's historical performance.
