As at the end of July 2026, the nominal local government discount rate is 5.1% and the real discount rate is 2.6%.

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.

IPART has recently completed a review of its methodology for determining the local government discount rate. Our updated method of calculating the discount rate is outlined in our June 2026 Final Report.
