## Content

**Intro:** The cash conversion cycle (CCC) tells you how many days your cash is locked up between paying suppliers and collecting from customers. It is the one number that links inventory, receivables and payables, which is why controllers and operations managers both watch it.

**Sections:**

#### How to use the calculator

**Body:** Pull annual revenue and COGS from the income statement, then average inventory, receivables and payables from the balance sheet. Averages across 12 month-ends are better than a single year-end figure. Enter a target DIO to see what a leaner inventory would release in cash. The chart sweeps that target so you can see how every 10 days of inventory translates into dollars.

**Bullets:**

- Use net sales, not gross, for DSO
- Use COGS, not sales, as the base for DIO and DPO
- Keep the same day count for all three ratios

#### The formula behind it

**Body:** DIO = inventory / COGS x days. DSO = receivables / revenue x days. DPO = payables / COGS x days. CCC = DIO + DSO - DPO. A negative CCC means suppliers fund your operation, which is common in distribution and rare in make-to-order manufacturing. Cash released is the DIO gap multiplied by daily COGS, since each day of inventory costs one day of cost of goods sold.

#### How to read the result

**Body:** A discrete manufacturer with a 90 to 130 day cycle is not unusual, because WIP and raw material dominate. Compare against your own trend and a few peers rather than a single benchmark. If DIO is the largest term, start with excess and slow-moving stock. If DSO is high, check for billing delays and disputed invoices. If DPO is low, review payment terms before stretching vendors, since late payment can cost you supply priority.

#### Common mistakes and ERP notes

**Body:** The most frequent error is mixing bases, for example dividing inventory by sales. Another is including intercompany balances or non-trade payables. In most ERPs the inputs come from inventory valuation reports, AR aging and AP aging as of the same cut-off date. Reconcile each to the general ledger before trusting the result.

**Bullets:**

- Exclude customer deposits and unbilled WIP from DSO unless you are consistent
- Include only trade payables in DPO
- Run it by plant or business unit for actionable insight

**Cta:** If the inputs live in different reports every month, we can wire a read-only query over your ERP so the cycle refreshes itself and you can ask which items or customers drive it.

**Faq:**

#### What is a good cash conversion cycle for a manufacturer?

**Answer:** There is no single good number. Make-to-stock and process manufacturers often run 60 to 100 days, while long-lead make-to-order shops can exceed 120. The useful measure is your own trend by plant and how it compares with direct peers. A shrinking cycle at the same growth rate means you are funding growth with less cash.

#### Should DIO use COGS or sales?

**Answer:** Use COGS. Inventory is carried at cost, so dividing by sales understates days on hand. Some analysts use sales for all three ratios to keep a common base, which is acceptable if you stay consistent, but the COGS basis is the standard definition for DIO and DPO.

#### Can the cash conversion cycle be negative?

**Answer:** Yes. If payables days exceed inventory plus receivable days, the cycle is negative and supplier credit funds operations. It happens in retail and some distribution. In manufacturing it usually signals long payment terms, customer prepayments or very fast turns, so check that the inputs are right.

#### How often should I recalculate it?

**Answer:** Monthly is the norm, aligned to the close. Use trailing twelve month revenue and COGS with the average of recent month-end balances to avoid noise from a single large shipment or purchase.
