The accounts payable (AP) turnover ratio is a valuable metric for understanding how efficiently your business pays its suppliers and manages cash flow. Your business’s AP turnover ratio gives you insights into your payment practices and helps you identify areas for improvement.
In this guide, we’ll break down what the AP turnover ratio is, how to calculate it, and what it tells you about your financial condition.
At-a-glance: Accounts payable turnover ratio basics
What is the accounts payable turnover ratio?
Your accounts payable (AP) turnover ratio measures how frequently your business pays off its accounts payable balance within a given period. A higher AP turnover ratio means you pay off your balance more quickly, while a lower ratio indicates that you're holding onto cash longer by making payments more slowly.
The AP turnover ratio is essentially a financial metric that provides a snapshot of short-term liquidity and payment practices, offering insight into cash flow and status of your vendor relationships.
What does the AP turnover ratio mean?
A high ratio signals prompt payments, often due to short payment terms, taking advantage of discounts, or improving creditworthiness.
A low ratio is more nuanced. It can reflect strategic cash flow management—like holding onto cash longer to invest in other areas—or extended payment terms, such as negotiating net 60 to net 90. However, a ratio that’s too low might also suggest late payments or cash flow issues, raising potential concerns.
What is a good AP turnover ratio?
There’s no universal benchmark for an ideal AP turnover ratio, as it varies by industry and business needs. Generally, a higher ratio indicates frequent payments, which can signal strong creditworthiness and reassure suppliers when extending credit.
However, a turnover ratio that’s too high might suggest over-purchasing or running low on inventory. It’s essential to compare your ratio to industry averages and consider your unique operational requirements when assessing what’s ideal for your business.
How to calculate your accounts payable turnover ratio
Here’s the typical accounts payable turnover ratio formula:
AP turnover ratio = Total net credit purchases / Average AP balance
Here’s how to calculate each component of the formula individually:
- Total net credit purchases: The total credit purchases added to your accounts payable during the period, excluding cash purchases and adjusted for returns.
- Average AP balance: Add the beginning and ending AP balances for the period, then divide by two.
You can calculate your AP turnover ratio for any accounting period that you want—monthly, quarterly, or annually. Many businesses calculate AP turnover ratios monthly and plot the results on a trendline to see how their ratio changes over time.
AP turnover ratio calculation example
Imagine that at the beginning and end of the year, you had $5,000 and $3,800 in your AP balance, respectively. During the year, you made total supplier purchases of $31,800 on credit and returned $500 of those goods. Using the AP turnover ratio formula from above, you calculate your annual AP turnover ratio to be 7.11:
$31,800 - $500 = $31,300 net credit purchases
($5,000 + $3,800) / 2 = $4,400 average AP balance
$31,300 / $4,400 = 7.11 AP turnover ratio
This means that you effectively paid off your AP balance just over seven times during the year.
How can you manage your AP turnover ratio?
Managing and improving your accounts payable turnover ratio requires understanding the factors that influence it and taking actionable steps to optimize your processes.
What influences your AP turnover ratio?
Your AP turnover ratio is dependent on many factors, including:
- Seasonality: Busy periods may result in a higher ratio, while slower periods can lead to a lower ratio.
- Product type: Businesses dealing with perishable goods often have higher ratios due to quicker payment cycles compared to those purchasing long-shelf-life items.
- Inventory turnover: Faster inventory turnover typically increases the ratio, as frequent purchases and payments are needed to maintain stock.
- Inventory management strategy: Overstocking can lead to a lower ratio, while consistently low inventory levels may result in a higher ratio due to frequent restocking.
How to improve your AP turnover ratio
If you notice that your AP turnover is off from industry averages or simply isn’t where you want it to be, there are plenty of things you can do to fix it:
- Negotiate better terms: Build strong supplier relationships and negotiate for more favorable payment terms.
- Streamline your AP process: Use AP automation software to simplify workflows, pay bills on time, and reduce invoice processing times.
- Leverage early payment discounts: Review payment terms and take advantage of discounts when paying early.
- Upgrade inventory management: Avoid over- or under-purchasing by using inventory management systems.
- Eliminate cash flow issues: Use projection software to ensure cash availability for timely payments.
And lastly, tracking your AP turnover ratio over time is also crucial. Monitoring how your ratio trends can reveal the impact of operational changes, like negotiating better payment terms. A decreasing ratio might signal success—or point to cash flow issues. Always evaluate it within the context of your broader financial picture.
Using KPIs to analyze your AP turnover ratio
While the AP turnover ratio provides insight into how efficiently you pay suppliers, it gains more meaning when analyzed alongside other financial KPIs. These comparisons help uncover patterns, diagnose inefficiencies, and optimize financial performance. Here’s how to use these metrics together.
1. AP turnover ratio and days payable outstanding (DPO)
How they work together: Days payable outstanding converts your AP turnover ratio into the average number of days it takes to pay suppliers. A higher AP turnover ratio corresponds to a lower DPO, indicating faster payments.
What to look for: Compare DPO to your supplier terms (e.g., net 30, net 60) to ensure payments are neither too early nor too late. Use this insight to align payment timing with cash flow needs while maintaining supplier trust.
2. AP turnover ratio and AR turnover ratio
How they work together: The AR turnover ratio measures how quickly you collect payments from customers. Comparing it with AP turnover helps evaluate your cash flow balance.
What to look for: If you collect receivables faster than you pay suppliers, you’re maintaining positive cash flow. If the opposite is true, consider strategies to speed up receivables or extend supplier payment terms to improve liquidity.
3. AP turnover ratio and percentage of discounts captured
How they work together: The percentage of discounts captured shows how often you take advantage of early payment discounts.
What to look for: If your AP turnover ratio is high but your discount percentage is low, you may be missing cost-saving opportunities. Aim to align fast payments with opportunities to reduce costs through discounts.
4. AP turnover ratio and inventory turnover ratio
How they work together: The inventory turnover ratio reflects how quickly you sell or use inventory. It impacts how often you purchase stock and, consequently, your AP turnover.
What to look for: If your inventory turnover is low, a high AP turnover ratio could indicate over-purchasing or inefficient stock management. Align inventory and AP strategies to avoid tying up cash in unsold goods.
Key takeaways
Comparing the AP turnover ratio with these metrics provides a fuller picture of your company’s financial health. For example:
- Rising late fees paired with a falling AP turnover ratio signals payment delays and inefficiencies.
- High DPO combined with low AR turnover might indicate cash flow strain.
- Frequent discounts captured alongside a high AP turnover ratio highlights strategic payment timing.
By evaluating the relationships between these KPIs, you can fine-tune payment strategies, improve cash flow, and reduce costs without jeopardizing supplier relationships.
