The "implied no-growth multiple" is 1 ÷ cost of equity — the P/E a company deserves if it never grows and pays everything out. It is the cleanest demonstration of why valuations fall when rates rise: nothing about the business changed, only the denominator.

The idea behind it

This calculator belongs to Valuation & Cost of Capital, where the mechanism it computes is explained step by step, with the formula, what each input means and where the simple model stops being right. Everything is computed in your browser; nothing you type is sent anywhere.

Instruments it applies to

  • Common Stock — A fractional ownership stake in a company — with voting rights, dividend claims and unlimited upside.
