What is Free Cash Flow?

The Free Cash Flow calculation tells you your free cash flow from a few simple inputs. The figure you are solving for here is the free cash flow, expressed in INR.

  • Capital expenditure — a money amount. Example: ₹30,000.

How to calculate it step by step

  • Write down the operating cash flow (for example, ₹1,10,000).
  • Write down the capital expenditure (for example, ₹30,000).
  • Apply the formula above to get your free cash flow.
  • Double-check the result with the Free Cash Flow Calculator.

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.
  • Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
