Discounted cash flow (DCF) analysis values an asset as the sum of its expected future cash flows, each translated into present dollars using a discount rate. It is finance’s foundational valuation method — the machinery inside real estate appraisals, private company valuations, and the NAVs of non-traded products — and its outputs are exactly as good as its assumptions.
How a DCF works
Three ingredients: projected cash flows over an explicit forecast period (property NOI year by year, company free cash flow), a discount rate expressing the required return for the risk, and a terminal value capturing everything beyond the forecast — in real estate, the assumed sale at an exit cap rate; in company valuation, a perpetuity-growth or exit-multiple estimate. Each cash flow divides by (1 + rate)^years; the sum is the value.
The method’s honesty problem is structural: the terminal value routinely represents half or more of the total — meaning a “ten-year cash flow analysis” is substantially a bet on one number in year ten — and the discount rate compounds its influence across every year. The standard sensitivities follow: a percentage point of discount rate, or 25–50 basis points of exit cap, can swing values by double-digit percentages, which is why professional DCFs publish sensitivity tables rather than point estimates, and why reading those tables is more informative than reading the headline value.
Where advisors meet DCFs in alternatives: the appraisal processes behind non-traded REIT and DST valuations (filings disclose the discount-rate and exit-cap assumptions — the two numbers that are the NAV, functionally); sponsor projections in offering materials, where the projected equity multiple and IRR are outputs of an implicit DCF whose rent-growth and exit assumptions deserve reverse-engineering; and fair-value marks on private assets generally. The diligence habits: compare assumed rates against current market evidence (not the sponsor’s history), check whether growth assumptions and discount rates are internally consistent (aggressive growth plus a low rate is double-counting optimism), and treat any DCF without disclosed assumptions as a conclusion, not an analysis.
FAQ
What is DCF in simple terms?
Valuing something by adding up all the cash it should produce, with each future dollar shrunk to reflect waiting and risk — the total is what the asset is worth today.
What's the biggest weakness of DCF analysis?
Assumption sensitivity: the terminal value and discount rate dominate the result, so small changes in either move the valuation dramatically — precision of output, not of truth.
Where do DCFs affect alternative investments?
Everywhere values are estimated rather than traded: property appraisals, non-traded product NAVs, sponsor return projections, and private asset marks all run on DCF machinery.
