Calculating cash flow for a small business involves tracking the actual cash moving in and out over a specific period. The core formula is Net Cash Flow = Total Cash Inflows - Total Cash Outflows. A positive result means more cash is coming in than going out, while a negative result indicates a potential shortfall.
It is calculated by taking earnings before interest, taxes, depreciation and amortization (commonly known as EBITDA) and subtracting capital expenditures and changes in working capital: Available Cash Flow = EBITDA - Capital Expenditures - Changes in Working Capital.

Ratios below 1.0 suggest potential cash flow issues, while ratios significantly above 1.0 point to healthy financial standing, with a Debt to Free Cash Flow ratio between 1.0 and 2.0 often considered strong.
