Free Cash Flow

Free Cash Flow

The cash the business actually produces after the bills are paid. Net income is an accounting number. EBITDA is a profitability number. Free Cash Flow is the actual cash that lands in the account, available to distribute, reinvest, or hold. The bridge from operational performance to ownership outcomes.

Definition

Free Cash Flow (FCF) is the cash a business generates after paying for everything required to keep it running. It is what the owner can actually take, reinvest, or save without breaking the business.

The simplified formula:

EBITDA
− interest paid (debt service)
− cash taxes (federal, state, owner-level pass-through)
− working capital change (receivables, inventory, payables)
− maintenance capital expenditures (replacing what wears out)
− growth capital expenditures (capacity additions)
= Free Cash Flow

Some owners and analysts compute Free Cash Flow to the Firm (before debt service) versus Free Cash Flow to Equity (after debt service). For owner decisions about distributions and lifestyle funding, FCF to Equity (after debt) is the relevant number. That is the cash actually available to the equity holder.

A worked example. A business produces $3M EBITDA. Debt service costs $400K per year. Cash taxes run $700K. Working capital absorbs $200K (growing receivables and inventory). Maintenance capex is $250K. Growth capex is $300K. The remaining $1.15M is Free Cash Flow. That is the number the owner can actually distribute, reinvest into ownership wealth, or save.

Why It Matters for Owners

Owners frequently confuse three different cash numbers, and the confusion costs them.

Net income is what the income statement says the business “earned.” It includes non-cash items like depreciation. It is an accounting number, not a cash number.

EBITDA is earnings before interest, taxes, depreciation, and amortization. It is a profitability proxy that valuations are built on. But you cannot deposit EBITDA. EBITDA does not account for what the business has to spend to keep operating.

Free Cash Flow is what is left after everything the business actually had to pay to stay in business this year. This is the number that hits the bank. This is the number that funds the owner’s life.

The trap most owners fall into is reading EBITDA as if it were FCF. A business with $3M EBITDA might have $1.8M FCF after debt service, taxes, and reinvestment. Or $1.2M. Or $400K. Same EBITDA. Wildly different ownership realities. The difference is the capital structure, the tax treatment, and how much the business has to spend on working capital and capex to grow.

Once an owner can see Free Cash Flow as the bottom-line number, three things change.

  • Capital allocation gets sharper. The question becomes “does this hire / acquisition / system investment increase or decrease FCF over a multi-year horizon?” instead of “can we afford it this month?”
  • Distribution decisions get cleaner. Distributions come from FCF, not from EBITDA. A business that distributes more than it generates in FCF is taking on debt or shrinking working capital, not creating wealth.
  • The Owner-Operator Trap becomes visible. If FCF only happens because the owner is working 60 hours a week, the trap is real. If FCF happens whether the owner shows up or not, the business is on the path to Independence Escape Velocity.

How It Connects to the OS

Free Cash Flow is the unit of measurement that ties operations to ownership.

  • Owner’s Scorecard™ Cash Flow dimension. The five-year FCF trajectory the owner is targeting. This is the headline number on the Cash Flow page.
  • Milestone 02 — Cash Flow Targets & Sources. The milestone where the owner specifies year-by-year FCF targets and maps them to sources (salary, distributions, bonuses, non-business income).
  • Milestone 04 — Owner’s Value (DCF). The Owner’s Value lens uses projected FCF as the numerator of the DCF calculation. The valuation the owner cares about most is built on the FCF the business will produce for them.
  • Milestone 10 — Three-Statement Model. The three-statement model is the engine that produces a defended FCF number every month and forecasts it forward.
  • Milestone 11 — Annual Budget. The annual budget projects FCF month by month for the coming year. Variance from budget gets caught in the Monthly Ownership Meeting.
  • Milestone 26 — Recruit Successor. Capital allocation decisions are made on Free Cash Flow. The owner allocates FCF across distributions, debt paydown, reinvestment, and external investments.

Without a clean FCF number, every decision in the chain (Scorecard targets, DCF valuation, three-statement model, annual budget, capital allocation) is built on a number the owner cannot fully trust.

What Done Looks Like

An owner who has Free Cash Flow installed as a working concept can answer five questions in 60 seconds.

  • “What was last year’s FCF?”
  • “What is this year’s FCF tracking toward?”
  • “How much of FCF goes to distributions, reinvestment, and savings?”
  • “If we hit the 5-year revenue target at the planned margin, what is the FCF profile?”
  • “How much FCF does the business produce when I am not in the seat?”

Each of those answers is a specific number. Each is grounded in the three-statement model. Each one ties to a decision the owner is making this quarter or this year.

The opposite signs (and the absence of working FCF). The owner answers in EBITDA. The owner says “we made $X” and means net income. Distributions get taken whenever cash is in the account, with no plan for working capital or reinvestment. The DCF valuation is missing or uses generic industry assumptions because the FCF projection has not been built.
