Free Cash Flow Calculator

Calculate FCF using the direct method (from operating cash flow) or the indirect method (from net income).

💰 Direct Method (From Operating Cash Flow)

FCF = Operating Cash Flow − Capital Expenditures

🔄 Indirect Method (From Net Income)

FCF = Net Income + D&A − ΔWC − CapEx

Alternative FCF Calculator (From Revenue)

Estimate free cash flow starting from revenue using operating margin, tax rate, and capital needs.

📈 Revenue-Based FCF Estimate

NOPAT − Net Capital Spending − ΔWC = FCF

FCF Yield Calculator

Calculate how much free cash flow you're getting per dollar invested in a stock.

📊 FCF Yield

FCF Yield = (FCF per Share / Stock Price) × 100

🏦 Free Cash Flow to Equity (FCFE)

FCFE = FCF + Net Borrowing − Debt Repayment

What Is Free Cash Flow?

Free cash flow (FCF) is the cash a business generates from operations after subtracting capital expenditures needed to maintain or grow its asset base. It represents the money actually available for shareholders — through dividends, share buybacks, debt repayment, or strategic acquisitions.

FCF = Operating Cash Flow − Capital Expenditures

Why FCF Matters More Than Net Income

Net income is an accounting figure that includes non-cash items like depreciation and can be influenced by accounting decisions (revenue recognition timing, asset write-downs, deferred taxes). Free cash flow strips away these distortions and shows the actual cash a company produces.

A company can report growing net income while burning cash — a dangerous mismatch. Conversely, capital-intensive businesses may show modest earnings but generate substantial free cash flow. This is why Warren Buffett focuses on "owner earnings," which is essentially free cash flow.

The Free Cash Flow Formula (Two Methods)

Direct method: Start with operating cash flow from the cash flow statement, then subtract capital expenditures. This is the simplest and most common approach.

FCF = Operating Cash Flow − CapEx

Indirect method: Start with net income, add back non-cash charges (depreciation and amortization), subtract changes in working capital, then subtract capital expenditures.

FCF = Net Income + D&A − ΔWorking Capital − CapEx

How to Calculate Free Cash Flow: Step by Step

1. Find Operating Cash Flow on the company's cash flow statement (also called "cash from operations"). 2. Find Capital Expenditures under "investing activities" on the same statement. 3. Subtract CapEx from OCF. The result is free cash flow. If FCF is positive, the company generates more cash than it needs to maintain its business. If negative, it's spending more than it earns — which may be fine for a growing company but is a red flag for a mature one.

FCF vs Net Income vs Operating Cash Flow

Understanding the differences between these three metrics is essential for proper financial analysis.

FCF Quality Checklist

Use these four criteria to quickly assess whether a company's free cash flow profile signals financial strength.

Positive FCF — The company generates more cash from operations than it spends on capital expenditures. Consistent positive FCF over 5+ years is a strong sign of a durable business.
FCF > Net Income — When free cash flow exceeds net income, earnings quality is high. This means the company converts its profits into actual cash rather than paper gains.
Consistent FCF Growth — Growing free cash flow year over year shows improving operational efficiency and pricing power. A 10%+ CAGR in FCF over 5 years is excellent.
Low CapEx-to-OCF Ratio — A CapEx/OCF ratio below 30% means the company keeps most of its operating cash flow as free cash flow. Asset-light businesses typically excel here.

5 Key Insights About Free Cash Flow

1
FCF is the ultimate reality check. A company can report rising earnings for years while free cash flow declines — a warning sign of accounting aggression. Always verify that reported profits translate into actual cash generation.
2
Negative FCF is not always bad. High-growth companies like Amazon or Tesla had years of negative FCF while investing heavily in capacity. The key question: is the company investing for future returns, or failing to generate cash from a mature business?
3
FCF yield is the cash-based P/E ratio. An FCF yield of 7% means you're buying $7 of annual cash flow for every $100 invested. Compare this to bond yields — if FCF yield exceeds the 10-year Treasury rate, the stock may offer better value.
4
Sector differences matter enormously. Tech companies routinely convert 25-35% of revenue to FCF. Utilities and industrials may convert only 5-10%. Always compare FCF margins within the same sector, never across different industries.
5
Buybacks + dividends should not exceed FCF. When a company pays out more than its free cash flow in shareholder returns, it must borrow or sell assets to fund the difference — an unsustainable practice that erodes long-term value.

Frequently Asked Questions

What is free cash flow and why does it matter?
Free cash flow (FCF) is the cash a company generates after accounting for capital expenditures needed to maintain or expand its asset base. FCF = Operating Cash Flow - Capital Expenditures. It matters because it represents the actual cash available for dividends, share buybacks, debt repayment, and acquisitions — making it the most reliable measure of a company's financial health.
How do you calculate free cash flow?
The most common free cash flow formula is: FCF = Operating Cash Flow - Capital Expenditures. You can also calculate it from net income: FCF = Net Income + Depreciation & Amortization - Changes in Working Capital - Capital Expenditures. Both methods should produce similar results when using consistent financial data from the cash flow statement.
What is a good FCF yield for stocks?
An FCF yield above 5% is generally considered attractive for value investors. FCF yield between 3-5% is average for the S&P 500, while yields above 8% may indicate undervaluation or a mature company returning significant cash. Growth stocks often have lower FCF yields (1-3%) because they reinvest heavily. Always compare FCF yield within the same sector.
What is the difference between free cash flow and net income?
Net income includes non-cash charges like depreciation and can be manipulated through accounting choices. Free cash flow measures actual cash generated, making it harder to distort. A company can report positive net income while burning cash (negative FCF), which is a red flag. Conversely, a company with negative net income but positive FCF may be healthier than it appears.
What is free cash flow to equity (FCFE)?
Free Cash Flow to Equity (FCFE) is the cash available specifically to equity shareholders after all expenses, reinvestment, and debt obligations. FCFE = FCF + Net Borrowing - Debt Repayment. It is used in equity valuation models like the FCFE discount model to estimate the intrinsic value of a company's stock.
