Accounts Receivable Days Formula

What are accounts receivable days and how are they calculated?


Accounts receivable days (A/R days) is a financial metric that measures the average time it takes customers to pay their invoices. This important measurement helps businesses evaluate their collection efficiency and cash flow management. The basic formula for calculating A/R days is:

A R Days=Average Accounts Receivable/Revenue×365

For example, if a company has:

  • Accounts Receivable: $500,000
  • Annual Revenue: $5,000,000
    The A/R days would be: (500,000/5,000,000) × 365 = 36.5 days

This metric helps businesses:

  • Evaluate collection efficiency
  • Assess credit policies
  • Project cash flow
  • Monitor payment trends
  • Identify potential issues

The interpretation of A/R days varies by industry and company policy. For instance, if a company offers 30-day payment terms, an A/R days value of 37-38 days might indicate room for improvement in collection processes, while significantly lower numbers might suggest overly strict credit terms.

What is the formula for calculating accounts receivable days and how is it applied?

The accounts receivable days calculation involves a two-step process that measures the average time customers take to pay their invoices. Here's how it works: 

Basic Formula:

A R Days=(Average AR/Net Revenue)×Number of Days

Step 1: Calculate Average AR

Average AR=(Beginning AR+Ending AR)/2

Step 2: Calculate Net Revenue

Net Revenue=Gross Revenue− Refunds Credits Allowances 

Practical Example:

Given:

  • Beginning AR: $10,000
  • Ending AR: $20,000
  • Annual Sales: $100,000
  • Period: 365 days

Calculation:

  1. Average AR = ($10,000 + $20,000) ÷ 2 = $15,000
  2. Proportion = $15,000 ÷ $100,000 = 0.15
  3. A/R Days = 0.15 × 365 = 54.75 days

This result indicates that, on average, it takes approximately 55 days for the business to collect payment from customers. The calculation can be adjusted for different time periods by changing the number of days (30 for monthly, 90 for quarterly).

How does accounts receivable (AR) automation work in practice?

AR automation digitizes the entire accounts receivable process, from initial credit evaluation through final payment reconciliation. The system follows a structured workflow that handles multiple aspects of the AR process:

Invoice Management:

  • Automatically generates invoices from sales data
  • Delivers invoices digitally to customers
  • Calculates and applies correct tax rates
  • Tracks invoice status in real-time
  • Maintains digital records of all transactions

Payment Processing:

  • Monitors different payment types
  • Matches invoices to sales orders
  • Flags payment issues (like expired cards)
  • Processes early payment incentives
  • Handles late payment fees

Collection Activities:

  • Sends automated payment reminders
  • Tracks payment due dates
  • Generates follow-up notices
  • Monitors customer payment patterns
  • Flags accounts requiring intervention

Credit Management:

  • Evaluates customer creditworthiness
  • Sets and monitors credit limits
  • Tracks credit usage
  • Identifies high-risk accounts
  • Updates credit terms automatically

The system integrates with existing ERP systems to pull customer data, sales information, and payment details, creating a streamlined process that reduces manual intervention and improves accuracy.

What does the accounts receivable days metric tell us about a business's financial health and operations?

Accounts receivable days provides crucial insights into a company's operational efficiency, financial health, and cash flow management capabilities. Collection Efficiency:

  • Lower AR days indicate effective collection processes
  • Quick payment collection suggests strong customer relationships
  • Efficient credit policies and procedures are in place
  • Demonstrates good customer credit assessment
  • Shows effective invoice management

Cash Flow Indicators:

  • Faster collections mean better cash flow
  • Lower AR days reduce working capital needs
  • Improved ability to meet financial obligations
  • Less reliance on external financing
  • Better liquidity management

Business Health Metrics:

  • Industry comparison benchmarking
  • Credit policy effectiveness
  • Customer payment behavior patterns
  • Collection process efficiency
  • Overall financial stability

For example, if a company's AR days decrease from 60 to 45 days, this indicates:

  • Improved collection efficiency
  • Better cash flow management
  • Stronger operational procedures
  • Enhanced financial stability
  • More effective credit policies

This metric helps management make informed decisions about credit terms, collection procedures, and overall financial strategy while maintaining healthy business operations.

What is considered a good accounts receivable days number and how does it vary by industry?

A good accounts receivable days number varies significantly by industry and business type, with no universal standard. Here's what the numbers typically indicate: General Guidelines:

  • Below 45 days is considered good for most industries
  • 30-50 days is typical for many businesses
  • 70+ days may indicate collection issues

Industry Variations:

Management and Enterprise Companies: 125.1 days

Oil and Gas Extraction: 110.9 days

Construction Industry: ~70 days

Factors affecting AR days include:

  • Industry standards

  • Customer payment terms
  • Market conditions
  • Business model type

For proper evaluation, businesses should:

  • Compare metrics with industry peers
  • Track trends over time
  • Consider business-specific factors

If a company's AR days exceed industry averages, they should consider implementing improvements such as:

  • Electronic invoicing for faster delivery
  • Payment reminder systems
  • Customer credit evaluations
  • Early payment discounts
  • Regular follow-up procedures

What other metrics are similar to accounts receivable days?

Days Sales Outstanding (DSO) is a very similar metric to accounts receivable days. Both metrics assess how efficiently a business collects payments from its customers. However, DSO is calculated differently, focusing specifically on credit sales rather than total net sales. The formula for DSO is:

DSO=(Accounts Receivable​/Credit Sales)×Number of Days


The key difference between the two metrics lies in the denominator. For accounts receivable days, the average AR is divided by total net sales, which includes both cash and credit sales. In contrast, DSO focuses only on credit sales, making it a more precise measure of how well a business manages its credit sales collections. Accounts receivable days provide a broader view of the overall collection efficiency, while DSO hones in on the effectiveness of credit management specifically. Both metrics are useful for evaluating the financial health and operational efficiency of a business.
