FCFF Calculator — Free Cash Flow to Firm

What this calculator estimates

Free cash flow to firm, or FCFF, estimates cash generated by operations after the investments needed to maintain or expand the business. It is measured before distributions to lenders and shareholders, so it is designed to represent cash available to all providers of capital. Analysts often use FCFF in an enterprise-value discounted cash flow model because the cash flow is not restricted to equity holders alone.

The calculator supports four equivalent starting points when the underlying statements are internally consistent: net income, EBIT, EBITDA, and cash flow from operations. The selected method changes which adjustments are needed, but it should not change the economic result. Using the same reporting period and consistent definitions is essential.

Field-by-field guidance

• Starting point: Select the metric you can source most reliably. Net income starts after interest and tax, EBIT starts before both, EBITDA also excludes depreciation and amortization, and cash flow from operations starts from a cash-flow-statement subtotal.
• Source amount: Enter the selected metric for one period. A negative amount is allowed because companies can report losses or negative operating cash flow. Do not mix quarterly source data with annual investment data.
• Depreciation and amortization: Enter the non-cash expense for the same period. It is added back under the net income and EBIT methods. Under the EBITDA method, only its tax shield is added because EBITDA already excludes the expense. It is not needed in the CFO method.
• Interest expense: Enter gross interest expense when using net income or CFO. The calculator adds back interest after tax because FCFF is calculated before payments to debt providers. Avoid using net interest unless that is the deliberate normalized assumption.
• Corporate tax rate: Use a marginal or normalized effective tax rate appropriate for the analysis. Higher tax rates reduce after-tax EBIT and the after-tax interest addback, while increasing the depreciation tax shield in the EBITDA formula. The input must remain between 0% and 100%.
• Fixed capital investment: Enter capital expenditures net of proceeds from asset sales. A higher positive value lowers FCFF. A negative amount can represent net asset disposals, but recurring FCFF analysis should distinguish sustainable disposals from one-time transactions.
• Working capital investment: Enter the increase in operating working capital, generally excluding cash and interest-bearing debt. A positive increase consumes cash and lowers FCFF; a negative amount reflects a release of working capital and raises FCFF. This field is not separately used when starting from CFO because CFO normally already incorporates working-capital movements.

How the formulas work

From net income, FCFF adds back depreciation and amortization, adds after-tax interest, and deducts fixed and working capital investment. From EBIT, the calculator first converts operating profit to after-tax operating profit, commonly called NOPAT, then adds depreciation and subtracts reinvestment. From EBITDA, it taxes EBITDA and separately adds the depreciation tax shield. From CFO, it adds after-tax interest and subtracts fixed capital investment.

These formulas can be written as:

• NI + D&A + Interest × (1 − tax) − Capex − ΔNWC
• EBIT × (1 − tax) + D&A − Capex − ΔNWC
• EBITDA × (1 − tax) + D&A × tax − Capex − ΔNWC
• CFO + Interest × (1 − tax) − Capex

Reading the outputs, chart, and table

The primary result is FCFF. A positive value means the business generated cash after reinvestment during the selected period. A negative value is not automatically a sign of distress: a growing company may deliberately invest more than current operating cash generation. Persistent negative FCFF, however, requires financing and should be evaluated against growth, returns on invested capital, and liquidity.

Cash before reinvestment shows the subtotal before fixed and working capital investment. Total reinvestment combines the deductions used by the selected method. After-tax interest adjustment isolates the financing adjustment included in net-income and CFO approaches. The cash flow bridge separates the source amount, formula adjustments, and investment deductions.

The contribution chart plots every active formula component. Bars above zero increase FCFF; bars below zero reduce it. The detail table applies the same components in order and displays the running cumulative total. Because the chart, table, summary, and Excel file all use one calculation model, the final cumulative row should always equal the displayed FCFF.

Practical checks and common mistakes

Reconcile the inputs to the same financial statements and period, normalize unusual items, and confirm that capital expenditure is not confused with depreciation expense. Working capital should focus on operating accounts rather than total current assets minus total current liabilities without adjustment. When comparing companies, consider accounting policy differences and cyclicality.
