What Constitutes Cash Flow When Valuing a Business?

June 2025

Cash flow is the movement of money in and out of a company over a period of time.  If the company’s inflows of cash are more than its outflows, its net cash flow is positive.  If outflows exceed inflows, it is negative.  Free cash flow is the money left over after a company’s operating expenses and capital expenditures.  

Cash flow is calculated many different ways depending on the purpose of the valuation.  Net cash flow is the excess of cash inflow over cash outflow.  The calculation of net cash flow when valuing a business must match the calculation of net cash flow used by the source of the base discount rate used in the valuation.  A common calculation of net cash flow when valuing a business is net income plus depreciation/amortization less maintenance capital expenditures.  Net cash flow is similar to net income but net income is net of expenses like depreciation that don’t require cash expenditures.  A common cash flow metric when valuing a business is EBITDA or earnings before interest, depreciation and amortization.  Its capitalization produces an enterprise or invested capital value since it doesn’t include interest expense.  

For accounting purposes cash flow is broken down as cash flow from operating activities, cash flow from investing activities, and cash flow from financing activities.  However, when valuing a business the total cash flow is typically capitalized into value. 

In summary, cash flow is calculated in a number for different ways when valuing a business depending on the purpose of the valuation.  Common measures of cash flow used to value a business are net cash flow and EBITDA.
