FAQs

How is free cash flow different from net income?

Net income is an accounting measure that includes non-cash items like depreciation, amortization, and stock-based compensation, and is affected by accrual timing. Free cash flow measures actual cash generated after capex, making it harder to manipulate and more directly tied to economic value creation.

What is a good free cash flow margin?

FCF margin varies widely by industry. Asset-light software companies may achieve 20–40%+ FCF margins. Capital-intensive industries like manufacturing or airlines may have low single-digit or even negative FCF margins during heavy investment periods. Comparing FCF margins within an industry is most meaningful.

Why do investors focus on free cash flow in valuation?

Investors use FCF as the basis for discounted cash flow (DCF) models because it represents real cash a company can distribute or reinvest. A business that earns high accounting profits but consumes all cash on capex has less intrinsic value than one that converts profits into distributable cash.

Free cash flow (FCF) is one of the most important financial metrics for evaluating a company's financial health and intrinsic value. It is calculated as operating cash flow minus capital expenditures (capex): FCF = Operating Cash Flow − Capital Expenditures. Unlike net income, which can be distorted by non-cash accounting items and accruals, free cash flow represents the actual cash a business generates after maintaining and expanding its asset base. Companies with strong, growing free cash flow can self-fund growth, repay debt, pay dividends, repurchase shares, or make acquisitions without relying on external financing. Free cash flow is particularly important in discounted cash flow (DCF) valuation, where future FCF streams are projected and discounted back to present value to estimate intrinsic worth. Analysts often prefer FCF to earnings because it is harder to manipulate—cash is ultimately more transparent than accrual accounting figures. Two variants are commonly used: levered free cash flow (LFCF), which accounts for interest payments and debt obligations (representing cash available to equity holders), and unlevered free cash flow (UFCF), which excludes the impact of financing (representing cash available to all capital providers before debt service). For capital-intensive businesses like manufacturing or telecom, capex consumes a large portion of operating cash flow, making FCF significantly lower than net income. For asset-light software or services businesses, FCF can approach or exceed net income. FCF margin (FCF as a percentage of revenue) is a key efficiency metric, especially in SaaS, where it supplements ARR and MRR growth metrics to show capital efficiency.
