As at the end of July 2025, the nominal local government discount rate is 3.9% and the real discount rate is 1.2%.
We have included the calculation of the local government discount rate in the WACC model spreadsheet, available on our website.
Every six months, IPART publishes the discount rate we recommend councils apply if they are using a net present value (NPV) approach to calculating local infrastructure contributions.
Our method of calculating the discount rate is outlined in our July 2025 Technical Paper, Modelling local infrastructure contributions in a present value framework. IPART is currently reviewing its methodology for determining the local government discount rate, which is set for completion early next year.
