IGR

Internal Growth Rate

Growth

Turkish: İçsel Büyüme Oranı

Abbreviation: IGR

Short definition

The internal growth rate is the growth cap that can be funded only with retained earnings and no new debt. It sits below SGR because leverage does not rise.

Detailed explanation

When the debt market is closed or the covenant cap is full, the binding cap is IGR. If ROA is not cash, the same cash illusion as in SGR applies.

If IGR is below the growth target, a dividend cut or an asset sale can raise internal cash; otherwise growth is cut.

Why it matters for the CFO

In a constrained year, “we can grow at SGR” is too optimistic if the debt door is shut.

How it is calculated

IGR ≈ ROA × b (yeni borç yok; b = dağıtılmayan oran)

New D = 0 is the difference from SGR. If ROA is not sustainable cash profit, the cap is paper.

Variables in the formula

  • ROA: return on assets
  • b: retention ratio

How to read it

IGR is the quantity of the first pecking-order rung. It moves with ROA and the dividend.
