Development margin

Project profit divided by net realisation. Tells you how much of every revenue dollar you keep after building and selling the project.

Formula

Development margin = (Net realisation − TDC) / Net realisation

WhereNet realisation = GRV less selling costs and GST.

Why it matters

Development margin is the second most-quoted residential feasibility ratio after profit on cost. ICs and financiers look at both because they capture different things: margin tells you about pricing power, profit on cost tells you about capital efficiency.

Worked example

Waterloo scheme: profit = $2,087,000, net realisation = $26,200,000.

Development margin = $2,087,000 / $26,200,000 = 8.0%.

For build-to-sell apartments, most developers target 15–20% development margin alongside 18–22% profit on cost.

Questions

Frequently asked

Is development margin the same as profit margin?

Conceptually yes; both are profit divided by revenue. Development margin is the term used in property development; profit margin is the broader term.

Why use both development margin and profit on cost?

They measure different things. A project can hit 20% margin but only 12% profit on cost if it is capital-heavy. Both need to clear hurdles to be a real go.
