> The net operating working capital calculator works out NOWC – operating current assets (excluding excess cash) minus non-interest-bearing current liabilities – the working capital needed to run the business.

## Inputs

- Current assets
- Excess cash and short-term investments
- Current liabilities
- Short-term debt (notes payable)

## Results

- Operating current assets
- Operating current liabilities
- Net operating working capital

## Formula

```
NOWC = (current assets − excess cash) − (current liabilities − short-term debt)
= cash needed + receivables + inventory − payables − accruals
```

## Explanation

NOWC differs from working capital by excluding financing items. Changes in NOWC appear in free cash flow: an increase uses cash.

### How to use the Net Operating Working Capital Calculator

- **Current assets**
- **Excess cash and short-term investments**
- **Current liabilities**
- **Short-term debt (notes payable)**

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

### How it works

Enter current assets, excess cash, current liabilities and short-term (interest-bearing) debt.

### 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

- **Operating current assets** = [Current assets] - [Excess cash and short-term investments]
- **Operating current liabilities** = [Current liabilities] - [Short-term debt (notes payable)]
- **Net operating working capital** = [Operating current assets] - [Operating current liabilities]

### Example values
