- Sustainable growth rate
Sustainable growth rate (SGR) is the maximum rate at which a company can grow revenue without having to invest new capital. If a company earns a 15% return on equity (ROE), it can grow 15% simply be reinvesting all the earnings in new opportunities. In order to grow faster, the company would have to invest more capital than its own earnings by using debt or equity financing.

Although companies can grow at extremely rapid rates for some time, such growth cannot typically be sustained. Valuation methods such as the
Gordon model and otherdiscounted cash flow models require a growth estimate than can be sustained for many years. Since sales growth is not necessarily profitable, in order to grow equity rather than issue it, ROE should be positive.Basic formula
SGR = ROE * (1 –
