Understanding Accounts Receivable Days: How To Calculate It?
In the ever-evolving business landscape, cash flow is paramount. Accounts Receivable Days (AR Days), a metric that measures how long it takes for a business to collect payment from its customers, is an essential KPI for evaluating financial health and operational efficiency. The lower the AR Days, the faster your company is converting sales into cash, which can significantly impact its ability to scale.
Did you know? According to a 2024 FathomHQ survey, businesses with an AR Days above 60 are twice as likely to face cash flow issues than those with AR Days below 40. By using FinanceOps.ai, businesses can automate collections, predict payment behaviors, and reduce AR Days significantly.

What Are Accounts Receivable Days?
Accounts Receivable Days (AR Days) measures the average time it takes for a company to collect payments from its customers after making a credit sale. This metric is a direct reflection of your credit policies, collection strategies, and customer engagement practices.
A low AR Days means your company is efficiently collecting payments, improving cash flow, and reducing the risk of overdue accounts. A high AR Days indicates that the company may face challenges in collecting payments, potentially leading to liquidity issues or inefficient collections processes.
Why AR Days Matter for Your Business
Here’s why AR Days should be a key focus for finance leaders:
Cash Flow: AR Days directly impact your working capital. The higher the AR Days, the more your business is at risk of cash flow disruption.
Customer Payment Behavior: A high AR Days might indicate that customers are struggling to pay on time or that your invoicing process needs attention.
Operational Efficiency: The longer you wait for payments, the more resources you must allocate to collections, which lowers overall efficiency.
FinanceOps.ai’s AI-powered automation helps businesses reduce AR Days by ensuring proactive engagement, personalized communication, and smarter resource allocation, all while maintaining compliance.
How to Calculate Accounts Receivable Days
The formula for calculating Accounts Receivable Days is fairly straightforward, and there are two primary methods to use:
Basic Formula:

Average Accounts Receivable Formula:

In these formulas:
Accounts Receivable refers to the amount owed by customers.
Total Credit Sales includes the total sales made on credit during the period.
Net Revenue is the total revenue minus any allowances or returns.
The Formula for AR Days
The following is an example to understand the AR Days calculation more effectively:
Example:
Let’s assume:
Beginning Accounts Receivable: $10,000
Ending Accounts Receivable: $20,000
Net Revenue: $100,000 (annual)
First, calculate the Average AR:
Average AR=10,000+20,0002=15,000\text{Average AR} = \frac{10,000 + 20,000}{2} = 15,000 Average AR=210,000+20,000=15,000
Then, calculate AR Days using the formula:

This means it takes about 55 days on average to collect payment from your customers.
