What is Free Cash Flow?

Why It Matters

Free Cash Flow matters because a company can report solid accounting profit while still running out of actual cash, since profit includes non-cash accounting items and doesn't account for real spending on equipment, infrastructure, or other capital investments. Free cash flow strips away those distortions, showing what's genuinely available to reinvest, pay down debt, or build a cash reserve, which is ultimately what determines whether a business can survive a downturn or fund its own growth without needing outside financing. For an early-stage or high-growth company, tracking free cash flow alongside burn rate and runway gives a much clearer, harder-to-manipulate picture of financial health than profit alone, since it's grounded in actual cash movement rather than accounting treatment. A business with consistently negative free cash flow depends on continued external funding to survive, regardless of what its income statement says.

Example

A company generates $500,000 in operating cash flow for the year but spends $180,000 on new equipment and infrastructure as capital expenditures. Free Cash Flow is $500,000 minus $180,000, which equals $320,000, the actual cash available to the business after covering both its operations and its capital investment needs for the year.

Frequently Asked Questions

• How is Free Cash Flow different from Net Profit?

  Net profit is an accounting measure that can include non-cash items like depreciation and doesn't subtract capital expenditures. Free cash flow reflects actual cash generated after accounting for real spending on operations and capital investment, making it a harder number to distort.

• Can a profitable company have negative Free Cash Flow?

  Yes, this is common, especially for growing companies investing heavily in equipment, infrastructure, or expansion, where capital expenditures can exceed operating cash flow even while the business is profitable on paper.

• How does Free Cash Flow relate to Runway?

  Runway measures how long a company can operate before running out of cash, based on its burn rate. Free cash flow, when negative, is effectively the burn rate driving that runway calculation, making the two closely connected.

• Why do investors pay close attention to Free Cash Flow?

  Because it's a harder number to manipulate through accounting choices than profit, and it directly indicates whether a business can fund its own growth and survive without needing continued external financing.

• Is a growing Free Cash Flow always a sign of a healthier business?

  Generally yes, but it's worth checking why it's growing. Free cash flow can rise because the underlying business is genuinely more profitable, or simply because a company has cut back on necessary capital investment, which might hurt growth or competitiveness over the longer term.
