The scale model

How margin behaves as volume grows — whether it improves, holds, or quietly deteriorates.

The deliverable

What it is

Growth improves margin only where costs are genuinely fixed. Where the cost base scales with volume, growth multiplies revenue and cost together and changes very little.

The costs that break plans are step costs — the additional facility, the next tier of system, the manager who becomes necessary at forty people. They arrive suddenly and were not in the line.

What it is made of

Each element is a constituent part of the component. Follow one to see the attributes it carries.

  1. The cost split

    Which costs are fixed, which vary with volume, and which do neither.

  2. The step points

    The volumes at which a new fixed cost becomes necessary.

    3 attributes: Volume threshold · Step size · What steps

  3. The trajectory

    The direction margin is actually moving as the organisation grows.

Step costs are knowable in advance and are almost never in the model. Find yours before growth finds them for you.
