What Is Days Working Capital?
Let me explain days working capital directly: it's the number of days it takes for a company to convert its working capital into revenue. If a company has more days of working capital, that means it's taking longer to turn that capital into sales, which points to inefficiency.
Understanding Days Working Capital
You need to know that working capital is the difference between a company's current assets—like cash, accounts receivable, and inventories—and its current liabilities, such as accounts payable and short-term debt. A positive working capital means assets cover liabilities, while a negative one shows the opposite. Days working capital goes beyond that by showing you exactly how many days it takes to convert this capital into revenue. A high number here tells you the company is inefficient, as it's slow to generate sales from its resources. If the number is low and decreasing, it could be because sales are rising. On the other hand, if it's high or climbing, sales might be dropping or the company is slow in collecting payments. Remember, compare this metric across companies in the same industry for a clear picture.
Days Working Capital Formula and Calculation
Here's how you calculate it: the formula is average working capital multiplied by 365, divided by sales revenue. Working capital itself is current assets minus current liabilities. For average working capital, if you're looking over a period like a year, average the working capital from the start and end, or use quarterly averages. Then multiply by the days in the year and divide by your sales figure from the income statement. You can average sales over periods too, depending on your analysis scope.
Limitations of Days Working Capital
Be aware that days working capital isn't perfect on its own. You can't tell if the number is good or bad without comparing it to similar companies in the industry. Also, track it over multiple periods to spot changes or trends. Sometimes ratios get distorted—if current assets spike while liabilities and sales stay flat, the days number rises, but that extra cash isn't necessarily a problem. That's why using averages over quarters gives you a more reliable view.
Example of Days Working Capital
Take a company with $10 million in sales, current assets of $500,000, and current liabilities of $300,000. Working capital is $200,000. Plug it in: ($200,000 times 365) divided by $10 million equals 7.3 days. Now, if sales rise to $12 million with the same working capital, it drops to 6.08 days. This shows higher sales mean faster conversion, making the company more efficient. A company with three days is twice as efficient as one with six for the same period, but always compare within the industry since standards vary.
Frequently Asked Questions
You might wonder, what is working capital? It's current assets minus current liabilities, representing short-term financial health. How do you calculate days working capital? Multiply average working capital by 365 and divide by sales revenue. Can you judge if it's good or bad alone? No, compare it to industry peers and over time for trends.
The Bottom Line
In summary, days working capital tells you how many days a company needs to convert working capital to revenue—the more days, the less efficient it is. A low number means quick conversion to sales, which is better, but always analyze it in context.
