Cash flow to firm is a company's operating cash flow with the after-tax cost of interest added back, giving the cash generated by operations before any payment to lenders or shareholders. It is commonly calculated as cash from operating activities plus interest expense multiplied by one minus the tax rate.

Unlike free cash flow to firm, it does not subtract capital expenditures. It measures the business's operating cash generation on a basis that does not depend on how much debt the company carries. It is not a GAAP line item and is calculated from figures reported in SEC filings.

Under US GAAP, ASC 230 classifies interest paid as an operating cash outflow, so reported operating cash flow (NetCashProvidedByUsedInOperatingActivities in XBRL) is already reduced by interest. That makes two otherwise identical companies look different if one is financed with debt and the other with equity. Adding back interest expense (InterestExpense), adjusted for the tax deduction it provided, removes that distortion. The tax rate is often the effective rate, income tax expense (IncomeTaxExpenseBenefit) divided by pretax income; some analysts use a statutory rate instead.

Definitions differ at the edges. Some calculations add back interest paid in cash rather than interest expense, which can differ because of capitalized interest, noncash amortization of debt costs, and payment timing. Others also exclude interest income, so the measure reflects only operating activity. Under IFRS, companies may classify interest paid as financing, in which case their operating cash flow already excludes it and the add-back would double count. Check the classification before comparing US and foreign filers.

The main use of cash flow to firm is as the numerator in enterprise-level multiples, such as enterprise value to cash flow to firm, which compare companies on a capital-structure-neutral basis. Subtracting capital expenditures from it gives free cash flow to firm. On its own it answers a narrower question than free cash flow: how much cash the operations produce for all capital providers before the company decides how much to reinvest.
