> The cash conversion cycle calculator works out how many days a company's cash is tied up in operations – days inventory outstanding plus days sales outstanding minus days payable outstanding – from the financial statements.

## Inputs

- Revenue
- Cost of goods sold
- Beginning inventory
- Ending inventory
- Beginning accounts receivable
- Ending accounts receivable
- Beginning accounts payable
- Ending accounts payable
- Days in the period

## Results

- Days inventory outstanding (DIO)
- Days sales outstanding (DSO)
- Days payable outstanding (DPO)
- Cash conversion cycle

## Formula

```
DIO = average inventory ÷ COGS × 365
DSO = average receivables ÷ revenue × 365
DPO = average payables ÷ COGS × 365
CCC = DIO + DSO − DPO
```

## Explanation

A shorter (or negative) cash conversion cycle means a business needs less working capital – Amazon and Apple famously collect from customers before paying suppliers. A lengthening CCC can signal problems collecting cash or selling stock.

### How to use the Cash Conversion Cycle Calculator

- **Revenue**
- **Cost of goods sold**
- **Beginning inventory**
- **Ending inventory**
- **Beginning accounts receivable**
- **Ending accounts receivable**
- **Beginning accounts payable**
- **Ending accounts payable**
- **Days in the period**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter revenue, cost of goods sold and the beginning and ending inventory, receivables and payables.

### Tips

- Use consistent periods (a year or a quarter) for flow figures and period-end values for balances.
- Average opening and closing balances when a ratio mixes a flow with a stock.
- Benchmark against competitors in the same industry.
- Read the ratio together with others – profitability, liquidity and efficiency tell different stories.

### Common mistakes to avoid

- Using sales instead of cost of goods sold for inventory ratios.
- Mixing gross, operating and net profit.
- Ignoring one-off items that distort a single year.

### What each result means

- **Days inventory outstanding (DIO)** = ([Beginning inventory] + [Ending inventory])÷2÷[Cost of goods sold]×[Days in the period]
- **Days sales outstanding (DSO)** = ([Beginning accounts receivable] + [Ending accounts receivable])÷2÷[Revenue]×[Days in the period]
- **Days payable outstanding (DPO)** = ([Beginning accounts payable] + [Ending accounts payable])÷2÷[Cost of goods sold]×[Days in the period]
- **Cash conversion cycle** = [Days inventory outstanding (DIO)] + [Days sales outstanding (DSO)] - [Days payable outstanding (DPO)]

### Example values

How the main result changes when **Revenue** changes and everything else stays at the example values above:

RevenueCash conversion cycle (days)1,000,00085.81,500,00066.32,000,00056.62,500,00050.73,000,00046.84,000,00042

## Worked example

Inputs — Revenue: $2,000,000; Cost of goods sold: $1,200,000; Beginning inventory: $180,000; Ending inventory: $220,000; Beginning accounts receivable: $150,000; Ending accounts receivable: $170,000; Beginning accounts payable: $100,000; Ending accounts payable: $120,000; Days in the period: 365.

Results — Days inventory outstanding (DIO) = 60.8 days; Days sales outstanding (DSO) = 29.2 days; Days payable outstanding (DPO) = 33.5 days; **Cash conversion cycle = 56.6 days**.

## FAQ

**What is a good cash conversion cycle?**
Shorter is better; it varies widely by industry.

**Can the cash conversion cycle be negative?**
Yes – when a company is paid before it pays suppliers.

**How can a business shorten its CCC?**
Sell inventory faster, collect receivables sooner and negotiate longer supplier terms.

**What formula does the Cash Conversion Cycle Calculator use?**
DIO = average inventory ÷ COGS × 365.
