======Operating Cycle======
The Operating Cycle is the heartbeat of a business's operations. Think of it as the total time a company needs to go from spending cash on raw materials to receiving cash from its customers after a sale. It's a key [[Efficiency Ratio]], showing how quickly a company can turn its investments in [[inventory]] into cold, hard cash. A shorter cycle is like a sprinter—fast, efficient, and quick to refuel. A longer cycle is more like a marathon runner who needs more resources to cover the same distance. For a [[value investor]], understanding this cycle is crucial because it provides a clear view into how well a company manages its core business activities. It's calculated by adding the time it takes to sell inventory to the time it takes to collect payment from customers. A healthy, stable, or shortening operating cycle is often a hallmark of a well-managed and potentially undervalued business.
===== The Nuts and Bolts: How to Calculate It =====
Calculating the operating cycle is a simple addition problem, but first, you need to find its two key ingredients from a company's financial statements—primarily the [[Balance Sheet]] and [[Income Statement]].
The formula is: **Operating Cycle = DIO + DSO**
Where:
  * **DIO** stands for [[Days Inventory Outstanding]].
  * **DSO** stands for [[Days Sales Outstanding]].
Let's break these down.
==== Days Inventory Outstanding (DIO) ====
Also known as //Inventory Days//, DIO tells you the average number of days a company holds onto its inventory before selling it. A lower DIO is generally better, as it suggests products are flying off the shelves and the company isn't tying up cash in goods that might become obsolete.
The formula to calculate it is:
**DIO = (Average Inventory / [[Cost of Goods Sold]]) x 365**
//Average Inventory// is typically the inventory at the beginning of the period plus the inventory at the end, all divided by two.
==== Days Sales Outstanding (DSO) ====
Also known as //Days Receivables//, DSO measures the average number of days it takes for a company to collect the cash from customers after a sale has been made. A low DSO is a great sign; it means the company has an effective collections process and gets its cash quickly. A high or rising DSO can be a red flag that customers are struggling to pay.
The formula is:
**DSO = (Average [[Accounts Receivable]] / [[Revenue]]) x 365**
//Average Accounts Receivable// is calculated similarly to average inventory, using the beginning and ending balances for the period.
=== Putting It All Together: An Example ===
Let's imagine a company, "Cap's Custom Caps," and look at its annual figures:
  * Revenue: $500,000
  * Cost of Goods Sold (COGS): $300,000
  * Average Inventory: $50,000
  * Average Accounts Receivable: $40,000
Now, let's calculate its operating cycle step-by-step:
  - **Step 1: Calculate DIO**
    DIO = ($50,000 / $300,000) x 365 = 60.8 days
    //It takes Cap's about 61 days to sell a hat after making it.//
  - **Step 2: Calculate DSO**
    DSO = ($40,000 / $500,000) x 365 = 29.2 days
    //After selling a hat, it takes Cap's about 29 days to get the cash from the customer.//
  - **Step 3: Calculate the Operating Cycle**
    Operating Cycle = 60.8 + 29.2 = 90 days
    //From start to finish, it takes Cap's Custom Caps 90 days to turn its investment in a hat into cash in the bank.//
===== Why Should a Value Investor Care? =====
The operating cycle isn't just an accounting exercise; it's a powerful lens for viewing a company's underlying health and management quality.
==== A Window into a Company's Health ====
A shorter and more stable operating cycle is a sign of efficiency. It means a company can fund its growth internally rather than relying on debt. This improves a company's [[liquidity]] (its ability to meet short-term obligations) and reduces the amount of [[working capital]] needed to run the business. A company that gets its cash back faster can reinvest it sooner—to develop new products, expand into new markets, or return it to shareholders.
==== Spotting Trends and Red Flags ====
A single number doesn't tell the whole story. The real insight comes from two things:
  * **Trends Over Time:** Is the company's operating cycle getting longer or shorter? A consistently lengthening cycle could signal trouble, such as slowing sales (rising DIO) or customers taking longer to pay (rising DSO).
  * **Industry Comparison:** It's essential to compare a company's operating cycle to its direct competitors. A grocery store will have a very fast cycle (days), while a company that builds airplanes will have a very long one (years). A company with a significantly shorter cycle than its peers is likely doing something right.
==== The Link to the Cash Conversion Cycle ====
The Operating Cycle is one half of an even more powerful metric: the [[Cash Conversion Cycle]] (CCC). The CCC takes the analysis one step further by also considering how long a company takes to pay its own suppliers ([[Days Payable Outstanding]] or DPO).
The formula is: **CCC = Operating Cycle - DPO**
By understanding the Operating Cycle first, you've already done most of the heavy lifting to uncover how a company truly manages its cash flow—a cornerstone of sound, long-term investing.
