Within the income approach to business valuation, two primary methods are used to convert expected future earnings into a present value of the enterprise: the capitalization of earnings method and the discounted cash flow (DCF) method. Both methods rest on the same fundamental principle - a business is worth the present value of the future economic benefits it is expected to generate - but they differ significantly in how they handle growth, risk, and the time horizon of the forecast. Choosing the right method is not a matter of preference; it depends on the stability and predictability of the business's cash flows.
The capitalization of earnings method is conceptually elegant. It takes a single, normalized measure of earnings - typically trailing twelve months of adjusted EBITDA, net cash flow to equity, or net income after normalization - and divides it by a capitalization rate. The cap rate is derived from the discount rate minus the expected long-term growth rate of the business: Cap Rate = Discount Rate – Long-Term Growth Rate. This formula is a mathematical shorthand for an infinite-horizon DCF model under the assumption that earnings grow at a constant rate into perpetuity.
The capitalization method is most appropriate when the business is mature and stable - when the historical earnings record is a reliable guide to future performance, when growth is expected to be modest and relatively constant, and when no major changes in the business model, market, or capital structure are anticipated. For a steady-state, owner-operated business with consistent revenues and predictable costs, the capitalization method is not a simplification - it is the most appropriate and defensible method available. Its advantages include transparency, simplicity, and ease of auditing by third parties.
The method's limitation is sensitivity to the single-period earnings figure. If the chosen earnings base is not truly representative - because of a one-time event, a year of unusual profitability or loss, or a business that is in transition - the capitalization method can produce a misleading result. An appraiser must exercise significant judgment in selecting the earnings base and must document that selection thoroughly.
The DCF method builds an explicit forecast of future cash flows, year by year, over a discrete projection period - typically five to ten years. Each year's projected free cash flow is discounted back to the present at the weighted average cost of capital (WACC). At the end of the discrete projection period, a terminal value is calculated - often using the Gordon Growth Model, which is equivalent to the capitalization method applied to the last projected year's cash flow. That terminal value is also discounted back to the present and added to the sum of the discounted annual cash flows to arrive at total enterprise value.
The DCF is most appropriate when the business's expected future cash flows will be meaningfully different from its current earnings. Common scenarios include: businesses emerging from a startup or turnaround phase; businesses with large, visible contracts or project pipelines that drive near-term growth; companies undertaking major capital investments that will suppress current cash flows while creating future value; and businesses in declining industries where cash flows are expected to erode over time. In all these cases, the trajectory of future cash flows - not just the current level - is the primary driver of value, and a multi-period DCF model captures that trajectory explicitly.
The DCF's strength is also its vulnerability. An explicit multi-year forecast requires assumptions about revenue growth rates, margin trends, working capital needs, and capital expenditure levels. Modest changes in growth rate or terminal value assumptions can produce very large swings in concluded value. This sensitivity makes the DCF a powerful tool in the hands of a skilled appraiser - and a dangerous one in the hands of an advocate who adjusts inputs to achieve a desired outcome. ValuEdge applies both methods where appropriate, cross-checks results against market multiple evidence, and documents all assumptions with specific support to ensure that the concluded value is robust and defensible across a range of reasonable scenarios.
