Gordon growth model

Value equals next period's cash flow divided by the discount rate minus the growth rate. It is the algebra behind almost every terminal value in use.

The formula requires growth to be below the discount rate, permanently. Where growth approaches the rate, the value tends to infinity, which is the mathematics telling you the assumption is impossible rather than the company being extraordinary.

Its sensitivity is worth internalising. At a 13% discount rate, moving perpetual growth from 5% to 7% raises the value by 33%.

Two assumptions, one answer, and no place to hide.
