Paying your suppliers on time is a direct reflection of how efficiently your business manages cash flow. If you’ve ever struggled with delayed payments, frequent vendor follow-ups, or an unpredictable accounts cycle, you’re not alone. Many businesses face these challenges, often without a clear understanding of how quickly they’re paying their bills or whether they’re utilizing credit terms effectively.
That’s where the accounts payable turnover ratio comes into play. It’s more than just a financial metric. It indicates how quickly your company pays off suppliers and how effectively you're managing short-term obligations.
In this blog, you’ll learn how to calculate the accounts payable turnover ratio, understand what it means for your business, and how to use it as a practical tool for improving financial discipline and operational efficiency.
The accounts payable turnover ratio, also known as payables turnover or creditors’ turnover, is a key liquidity metric that helps you evaluate how efficiently your business pays its short-term obligations to suppliers and vendors. Specifically, it measures the frequency with which your company settles its accounts payable within a given accounting period, typically on an annual basis.
Did You Know? On the balance sheet, accounts payable appear as a current liability.
For U.S. businesses working with multiple vendors or relying on trade credit, this ratio serves as a practical indicator of financial discipline. When calculated and tracked regularly, it becomes a powerful tool for cash flow forecasting and operational decision-making.

Understanding what the accounts payable turnover ratio represents is just the first step. Let’s break down how it’s calculated so you can start applying it to your financial data with confidence.
To calculate the accounts payable turnover ratio, you’ll need two key figures:
Net Credit Purchases: Total purchases made on credit during the period, excluding returns.
Average Accounts Payable: The average of beginning and ending accounts payable balances for the same period.
Formula:
Accounts Payable Turnover Ratio = Net Credit Purchases / Average Accounts Payable
1. Determine Net Credit Purchases
Use the total credit purchases made from suppliers. Exclude cash purchases and any items returned to suppliers.
Note: Some businesses use Cost of Goods Sold (COGS) instead of net credit purchases.
2. Calculate Average Accounts Payable
Use this simple formula:
(Beginning AP Balance + Ending AP Balance) ÷ 2
Locate both balances in the current liabilities section of your balance sheet.
Note: Ensure the period aligns with your net credit purchases, which are typically made on a monthly, quarterly, or annual basis.
Once you've calculated your accounts payable turnover ratio, the next step is to convert it into Days Payable Outstanding (DPO), a practical measure of how long your business typically takes to pay supplier invoices on average. Let’s find out how.
DPO helps you assess whether your payment cycle is too short (potentially missing out on working capital leverage) or too long (risking vendor relationships or penalties).
Formula:
Days Payable Outstanding (DPO) = Number of Days in Period / Accounts Payable Turnover Ratio
Use the appropriate period based on your reporting cycle:
Annual DPO = 365 ÷ AP Turnover Ratio
Quarterly DPO = 90 ÷ AP Turnover Ratio
Monthly DPO = 30 ÷ AP Turnover Ratio
By tracking both AP turnover and DPO, your finance team can gain a better understanding of payment behavior, vendor dynamics, and opportunities to fine-tune its working capital strategy.

To see how these calculations work in practice, let’s look at an example that illustrates how to compute the accounts payable turnover ratio and interpret the results.
To better understand how the accounts payable turnover ratio translates into payment behavior, let’s examine two companies, both with Net 60 terms from their suppliers (say), but with very different days payable outstanding (DPO) outcomes.
Step 1: Average AP = ($208,000 + $224,000) ÷ 2 = $216,000
Step 2: AP Turnover Ratio = $1,250,000 ÷ $216,000 = 5.8 times
Step 3: DPO = 365 ÷ 5.8 = 63 days (approximately)
What It Means: Company A takes an average of 63 days to pay its suppliers, which is slightly longer than the Net 60 terms. While this may support short-term liquidity, persistent delays can affect vendor trust and future credit terms.
Step 1: Average AP = ($80,000 + $95,000) ÷ 2 = $87,500
Step 2: AP Turnover Ratio = $925,000 ÷ $87,500 ≈ 10.57 times
Step 3: DPO = 365 ÷ 10.57 ≈ 35 days (approximately)
What It Means: Company B pays its suppliers in about 35 days, well ahead of the Net 60 schedule. While this may strengthen supplier relationships, it can also reduce available working capital that may be used more strategically elsewhere.
Understanding the calculation is only half the picture; the real value lies in how you interpret the ratio and apply it to your business decisions.
Understanding your accounts payable turnover ratio helps you make smarter cash flow decisions. There’s no one-size-fits-all answer to what makes a DPO or AP Turnover Ratio “good”. It depends on your industry, supplier terms, and how well your business balances vendor relationships with cash flow needs. Let’s find out how.
A meaningful AP turnover ratio or DPO must be compared to others in your sector.
Example: A DPO of 40 days may be considered low for a retail brand that receives Net 60 terms from suppliers, but is perfectly acceptable for a fast-moving e-commerce brand in the fashion space with tighter inventory cycles.
Instead of focusing solely on the number, examine trends quarter-over-quarter or year-over-year.
Example: If your DPO drops from 60 to 40 days while sales stay constant, it may signal missed opportunities to optimize working capital.
Your DPO should support your business model and liquidity needs, rather than working against them. It reflects how well you manage vendor contracts and payment terms. Therefore, regularly evaluate your agreements to ensure they align with your cash flow strategy.
Example: If your supplier offers a 2% discount for payments made within 15 days, and your average DPO is 45 days, you may be missing out on significant cost savings.
Pro Tip: Take advantage of Net 30, 45, or 60 terms when possible, without harming your relationships.
