What is Free Cash Flow (FCF)?
Free Cash Flow (FCF) is the cash a business generates from operations after paying for capital expenditure needed to maintain and grow the business. It is the cash truly available to reward shareholders, repay debt or reinvest. Understanding this is the first step to using the Free Cash Flow Calculator effectively, because the quality of your result depends on the assumptions you feed in. Strong, consistent FCF is a hallmark of a healthy company and underpins dividends, buybacks and debt reduction. Once you are clear on the concept, the calculator simply does the arithmetic for you — quickly, consistently and without errors.
How does the Free Cash Flow Calculator work?
The calculator applies a standard, well-established formula so the result is consistent and reliable. In simple terms, it works out FCF = operating cash flow − capital expenditure. The core formula is:
you can also compute FCF yield by dividing FCF by market capitalisation. The tool does this instantly and re-calculates the moment you change any input, so you can test different scenarios in seconds — something that would take much longer, and be far more error-prone, on paper or in a spreadsheet.

Doing this calculation manually means juggling powers, percentages and long formulas where a single slip changes the answer. The Free Cash Flow Calculator handles all of that for you and lets you compare multiple scenarios side by side, so you can see exactly how a change in one number affects the outcome. It is the fastest way to turn a rough idea about Free Cash Flow (FCF) into a concrete, reliable figure you can plan around — on any device, at any time, for free.

Because you can see the outcome change in real time, the Free Cash Flow Calculator is as much a learning tool as a planning one: it builds an intuitive feel for how each variable — amount, rate, tenure or price — affects the final number.
Things to keep in mind
One year of FCF can be lumpy due to large capex. Look at the trend over several years and distinguish maintenance from growth capex. Remember that any calculator is only as good as its inputs and the assumptions built into it. Markets, interest rates, charges and tax rules change over time, so treat the output as a well-informed estimate rather than a guarantee. For decisions involving significant money or tax, confirm the current rules and consider speaking to a qualified financial adviser.
