Free Cash Flow Calculator
Calculate Free Cash Flow by subtracting Capital Expenditures from Operating Cash Flow to measure cash remaining after operating and capital investment needs.
Use this calculator to estimate Free Cash Flow by subtracting Capital Expenditures from Operating Cash Flow. Enter both values for the same accounting period and in one currency. Enter CapEx as a zero or positive spending amount; dollar signs are illustrative, and currencies are not converted.

Estimate Free Cash Flow from Operating Cash Flow and Capital Expenditures for the same period.
Free Cash Flow Example
Static example using the simplified formula: Operating Cash Flow $250,000 − Capital Expenditures $80,000 = $170,000 Free Cash Flow. CapEx as a share of OCF: $80,000 ÷ $250,000 × 100 = 32.0%. Free Cash Flow Conversion: $170,000 ÷ $250,000 × 100 = 68.0%. The entered amounts are assumed to cover the same period; this example is not calculated from form inputs.
About this calculator
What Is Free Cash Flow?
Free Cash Flow (FCF) is a cash-flow measure that, in this Tool, estimates Operating Cash Flow remaining after the entered capital spending. It is a simplified business-analysis definition; other Free Cash Flow definitions are used for different purposes.
Free Cash Flow Formula
Free Cash Flow = Operating Cash Flow − Capital Expenditures (CapEx). Enter CapEx as a zero or positive spending amount; the calculator subtracts it.
What Is Operating Cash Flow?
Operating Cash Flow (OCF) measures cash generated or used by operating activities during a period. This Tool takes OCF as an input and does not recreate its calculation. See the live Operating Cash Flow Calculator for a simplified indirect-method estimate.
What Are Capital Expenditures?
Capital Expenditures, or CapEx, generally represent cash spent to acquire, improve or extend the useful life of long-term productive assets, such as machinery, equipment, buildings, leasehold improvements, technology infrastructure or capitalized software. Use amounts consistent with your financial statements and accounting policies; this Tool does not prescribe accounting treatment.
Maintenance and Growth CapEx
Some analysts distinguish maintenance CapEx from growth CapEx. This Tool uses total entered Capital Expenditures; it does not require a split or calculate alternative Free Cash Flow definitions.
What Does Positive Free Cash Flow Mean?
Positive FCF means Operating Cash Flow exceeds the entered CapEx for the period. Possible uses can include debt repayment, reinvestment, acquisitions, distributions, dividends, share repurchases or liquidity reserves; these are examples, not recommendations. Higher positive FCF may also reflect lower capital investment, an asset-light structure or mature operations. Positive FCF alone does not establish financial health, and higher FCF is not automatically better.
What Does Zero Free Cash Flow Mean?
Zero FCF means Operating Cash Flow and entered Capital Expenditures are equal under this formula. The result is not automatically good or bad.
What Does Negative Free Cash Flow Mean?
Negative FCF means the entered Capital Expenditures exceed Operating Cash Flow under this formula. OCF may itself be negative. Expansion, equipment replacement, major projects, weaker OCF, working-capital pressure, business-model differences and temporary investment cycles may be relevant, but this calculator does not diagnose the cause or classify the business.
Does Negative Free Cash Flow Mean a Business Is Failing?
No. Growth spending, asset replacement and other investment cycles can create negative FCF during a period. The result alone does not establish business failure or financial distress, and this Tool does not diagnose its cause.
Free Cash Flow vs. Operating Cash Flow
OCF measures cash generated or used by operating activities; FCF subtracts CapEx from OCF. When CapEx is positive, FCF is lower than OCF. See the live Operating Cash Flow Calculator for the separate operating-cash-flow measure.
Free Cash Flow vs. Net Income
Net Income is an accounting earnings measure; FCF is a cash-flow measure. Depreciation, amortization, operating balance changes, capital expenditures and other non-cash or timing items can make them differ. See the live Net Profit Margin Calculator for a profitability measure; Net Income and FCF are not interchangeable.
Free Cash Flow vs. EBITDA
EBITDA is an earnings measure before interest, taxes, depreciation and amortization. FCF measures OCF after CapEx. EBITDA is not Free Cash Flow. See the live EBITDA Margin Calculator for the distinct margin measure.
Free Cash Flow vs. the Cash Flow Calculator
This Tool focuses on the financial-analysis formula OCF minus CapEx. The separate Cash Flow Calculator estimates cash inflows, outflows, net cash movement and monthly cash balances. It is for cash-flow planning, not this Free Cash Flow calculation.
CapEx as a Percentage of Operating Cash Flow
When OCF is positive, CapEx as % of OCF = CapEx ÷ OCF × 100. This describes the entered CapEx relative to entered OCF; the calculator does not compare it with a universal benchmark. When OCF is zero or negative, the percentage is N/A.
Free Cash Flow Conversion
When OCF is positive, Free Cash Flow Conversion = FCF ÷ OCF × 100. It describes the portion of the entered OCF remaining after entered CapEx. It has no benchmark band here; when OCF is zero or negative it is N/A.
Other Free Cash Flow Definitions
“Free Cash Flow” can refer to more than one financial measure. This Tool uses only the simplified formula OCF minus CapEx; it does not calculate Free Cash Flow to the Firm (FCFF), Free Cash Flow to Equity (FCFE), levered Free Cash Flow or unlevered Free Cash Flow.
Use Consistent Accounting Periods
Enter OCF and CapEx for the same period and in the same currency. Match annual OCF with annual CapEx and quarterly OCF with quarterly CapEx. Do not combine different periods without converting them consistently.
Free Cash Flow and Financial Health
FCF is one cash-flow measure; positive FCF does not by itself establish financial health, and negative FCF does not by itself indicate financial distress. Consider the business context, investment cycle, working capital, liquidity, profitability and financing needs. This Tool does not score a business, value it or recommend what to do with cash.
Frequently asked questions
What is Free Cash Flow?
In this Tool, Free Cash Flow estimates Operating Cash Flow less Capital Expenditures for the same period.
How do you calculate Free Cash Flow?
Subtract positive-or-zero Capital Expenditures from Operating Cash Flow: FCF = OCF − CapEx.
What is the difference between Free Cash Flow and Operating Cash Flow?
Operating Cash Flow reflects operating activities; Free Cash Flow subtracts Capital Expenditures from it.
Is Free Cash Flow the same as Net Income?
No. Net Income is an accounting earnings measure; FCF is a cash-flow measure after CapEx.
Is Free Cash Flow the same as EBITDA?
No. EBITDA is an earnings measure. FCF is Operating Cash Flow after Capital Expenditures.
What are Capital Expenditures?
CapEx generally means cash spent on acquiring, improving or extending the useful life of long-term productive assets.
Is positive Free Cash Flow always good?
Not automatically. Positive FCF means OCF exceeds entered CapEx for the period, but alone it does not establish financial health.
Is negative Free Cash Flow always bad?
No. Investment in growth, replacement assets or major projects may contribute to negative FCF; this result does not diagnose cause.
Why can a growing company have negative Free Cash Flow?
Growth spending or other investment may exceed Operating Cash Flow during a period. The Tool does not judge whether that investment is appropriate.
What happens if Capital Expenditures are zero?
When CapEx is zero, Free Cash Flow equals Operating Cash Flow.
What is Free Cash Flow conversion?
When OCF is positive, FCF conversion is FCF divided by OCF, expressed as a percentage.
Is this the same as FCFF or FCFE?
No. This Tool uses the simplified OCF-minus-CapEx formula and does not calculate FCFF or FCFE.
This Tool uses the simplified formula Free Cash Flow = Operating Cash Flow minus Capital Expenditures; other Free Cash Flow definitions exist. It does not calculate FCFF, FCFE, levered or unlevered Free Cash Flow and does not replace a formal cash-flow statement. Results depend on user-entered information. Operating Cash Flow and CapEx should cover the same period and currency. CapEx classifications can vary by accounting policy. Positive FCF does not by itself establish financial health; negative FCF does not by itself establish distress. Informational only; this is not accounting, tax, legal, investment or financial advice.
