Definition
Discounted Cash Flow (DCF) is a valuation method that determines the present value of an investment by discounting projected future cash flows back to today using a required rate of return.
DCF analysis is built on the Time Value of Money (TVM) principle: future cash flows are worth less than cash received today.
Core Components
- Projected Cash Flows: Annual income after operating expenses and capital expenditures.
- Discount Rate: Required return reflecting risk and opportunity cost.
- Holding Period: Investment time horizon (often 5–10 years in real estate).
- Terminal Value: Estimated resale value at exit.
Basic Formula
Present Value = Σ [ Cash Flowt ÷ (1 + r)t ]
Where:
- t = time period
- r = discount rate
Application in Real Estate
- Project annual Net Operating Income (NOI)
- Subtract capital expenditures and leasing costs
- Estimate sale price using an exit cap rate
- Discount all cash flows to present value
Example
A property generates projected annual cash flows of $500,000 for 5 years, and is expected to sell for $8,000,000 at the end of Year 5. Using a 9% discount rate, each annual cash flow and the terminal value are discounted back to present value to determine the property’s intrinsic worth.
Why Investors Use DCF
- Captures timing differences in cash flows
- Incorporates growth assumptions
- Accounts for risk via discount rate
- Provides more nuanced valuation than a simple cap rate
Common Pitfalls
- Unrealistic growth assumptions
- Improper discount rate selection
- Overreliance on terminal value
- Ignoring sensitivity analysis
