Terminal growth rate is the assumed long-term rate at which a company’s cash flow continues to grow beyond the explicit forecast period in a discounted cash flow model. It is typically used to estimate the continuing value of a business after the years that are projected in detail.
Why terminal growth rate matters
In valuation work, analysts often forecast cash flow for a limited number of years and then apply a long-term growth assumption for the period beyond that forecast. The terminal growth rate helps translate those later cash flows into a single continuing value estimate. Because this assumption affects the ending value of the model, it can have a meaningful impact on the final result, especially when paired with terminal value.
How it is used in valuation
The terminal growth rate is most commonly applied in the perpetual growth version of a discounted cash flow model. After projecting cash flow over a defined forecast horizon, the model assumes that cash flow continues growing at a stable rate into the future. This rate is usually kept modest because it is meant to reflect a mature, sustainable long-term state rather than a high-growth phase.
What a reasonable assumption looks like
A reasonable terminal growth rate should be consistent with long-term economic conditions and the expected maturity of the business. If the assumption is set too high, the valuation can become unrealistically aggressive. If it is set too low, the model may understate continuing business value. The key point is not precision, but using a stable assumption that fits the economic reality of the company being valued.
Terminal growth rate in context
Terminal growth rate is not a measure of current performance. It is a simplifying assumption used to represent the period after detailed forecasts end. For that reason, it is best understood as a valuation input rather than as a standalone business metric.
FAQ
Is terminal growth rate the same as revenue growth?
No. Terminal growth rate is a long-term valuation assumption used after the explicit forecast period, while revenue growth usually refers to actual or forecast business growth over a defined period.
Does a higher terminal growth rate increase valuation?
Yes. All else equal, a higher terminal growth rate increases the continuing value in a discounted cash flow model.
Is terminal growth rate only used in DCF models?
It is mainly associated with discounted cash flow valuation, especially the perpetual growth approach to estimating continuing value.
