A discounted cash flow analysis estimates value by converting forecast future cash flows into present value using a selected discount rate.
Definition
A discounted cash flow, or DCF, model projects future cash flows and discounts them to reflect the time value of money and risk assumptions. It usually includes a detailed forecast period and a terminal value for later years. For an engineering firm, forecasts may depend on assumptions about fees, staffing, utilization, margins, backlog conversion, working capital, and reinvestment. The result changes when forecasts, discount rates, or terminal value assumptions change. Owners can use a DCF to see which expectations drive an estimate and to compare scenarios. The method does not establish that projected work will be won or that cash flows will occur as forecast. It is not a sale offer or a guarantee of value. A DCF is a model whose usefulness depends on clear, supportable assumptions. The AICPA provides resources on valuation services.
How owners use it
- Review the cash flow forecast, discount rate, and terminal value assumptions as separate drivers of the result.
- Compare scenarios that vary expected backlog conversion, labor costs, collection timing, or growth assumptions.
- If a forecast cash flow of $110,000 one year from now is discounted at 10%, its present value is $110,000 ÷ 1.10 = $100,000.
- Use the model to understand how operating assumptions influence estimated value, not as a promise of future performance.
