What is the present value of the cash this business is expected to generate?
The income approach values a business on the earnings or cash flow it is expected to generate. The two methods are capitalisation of future maintainable earnings, which divides a single sustainable earnings figure by a capitalisation rate, and discounted cash flow, which forecasts cash flow year by year and discounts it to present value.
A single sustainable earnings figure is divided by a capitalisation rate, which is the discount rate less sustainable long-term growth. This suits stable, mature businesses where one year of normalised earnings fairly represents the future.
Cash flows are forecast year by year, each is discounted to present value, and a terminal value is added. This suits businesses with a forecastable change in trajectory: growth, a turnaround, a contract rolling off, or a site opening.
A discount rate is not selected from a table. It is built from layers, each of which compensates for a risk the reader can recognise: a risk-free rate taken from long-dated Australian Government bond yields (Source: RBA, Statistical Tables F2 Capital Market Yields), an equity risk premium for owning a business rather than a bond, a size premium because smaller companies are riskier than listed ones, an industry risk premium for the sector's own cyclicality and regulation, and a company-specific loading for customer concentration, key person dependence, record quality and geography.
Summing those layers gives a cost of equity. Where the business is valued on invested capital, that is blended with the after-tax cost of debt to produce a weighted average cost of capital. The capitalisation rate is then the discount rate less sustainable long-term growth.
Established trading businesses with reliable earnings: medical, dental and allied health practices, accounting and legal firms, trades and services businesses, franchises, recurring-revenue software, and transport operators with genuinely contracted work.
A defensible valuation considers all three approaches, applies the ones that fit, and explains why the others were given little or no weight. A detailed report sets that reconciliation out in full.
