DCF vs Residual Income
A DCF model estimates value from projected free cash flows discounted to today. A Residual Income model starts from book value and adds the present value of earnings above the cost of equity. DCF is commonly used for operating companies; Residual Income is commonly used for banks and lenders, where free cash flow is hard to define.
Side by side
| Attribute | DCF (Discounted Cash Flow) | Residual Income Model |
|---|---|---|
| What it values | Future free cash flows available to all capital providers | Book value plus earnings above the cost of equity |
| Starting point | Current free cash flow | Current book value per share |
| Discount rate | WACC (weighted average cost of capital) | Cost of equity |
| Key inputs | Free cash flow, growth rates, WACC, terminal growth | Book value, return on equity, cost of equity, growth |
| Where most of the estimate comes from | Terminal value, often the majority of the total | Book value today, with less weight on the distant future |
| Typically used for | Operating companies with meaningful cash flows | Banks and lenders with meaningful book values |
| Main limitation | Highly sensitive to terminal growth and discount rate | Depends on book value being reported reliably |
When each model is typically used
DCF (Discounted Cash Flow)
Companies whose cash flows track their operations — technology, consumer, industrial, and healthcare businesses. Most of the estimate usually sits in the terminal value, so results are sensitive to long-run growth and discount rate assumptions.
Read the definitionResidual Income Model
Banks and other lenders, where borrowing and lending are the business itself, so free cash flow is not a meaningful measure. Book value is a real anchor for these companies, and the model asks whether return on equity exceeds the cost of equity.
Read the definitionHow StockFind uses them
StockFind uses DCF as the default model. It switches to Residual Income for banks and lenders, identified from the company's SEC industry classification. Both models show their assumptions, and every output is labelled as a model estimate that depends on those inputs.
Common questions
Can DCF and Residual Income give different estimates?
Yes. In theory the two models reach the same value when their assumptions are consistent. In practice they rarely do, because they rest on different inputs — cash flow forecasts for DCF, book value and return on equity for Residual Income.
Why is DCF not typically used for banks?
For a bank, borrowing and lending are the operating business, so the line between operating cash flow and financing cash flow breaks down. That makes free cash flow hard to define, while book value and return on equity remain meaningful measures.
What happens when return on equity equals the cost of equity?
Residual income is zero, so the Residual Income model estimate equals book value. Earnings above the cost of equity add to the estimate; earnings below it reduce it.
