> The cash flow to debt ratio calculator measures how well a company's operating cash flow (or free cash flow) covers its total debt – and how many years it would take to repay the debt from cash flow.

## Inputs

- Operating cash flow
- Capital expenditure
- Total debt

## Results

- Cash flow to debt ratio
- Free cash flow to debt ratio
- Years to repay debt from operating cash flow

## Formula

```
Cash flow to debt = operating cash flow ÷ total debt
Years to repay = total debt ÷ cash flow
```

## Explanation

A ratio above 1 means the company could repay all its debt from one year of cash flow. Analysts sometimes use free cash flow (after capital expenditure) for a stricter test.

### How to use the Cash Flow to Debt Ratio Calculator

- **Operating cash flow**
- **Capital expenditure**
- **Total debt**

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

### How it works

Enter operating cash flow, capital expenditure and total 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.
