# Data Sources

Our KDR cost estimates use data from ABS, builder pricing guides, government fee schedules, and community sources.

We review and update our data sources quarterly, aligned with the ABS construction cost index release schedule. When the ABS publishes updated indices (typically March, June, September, and December), we recalibrate our city multipliers and cost bands. Fee schedules are checked against council websites at the start of each financial year when most councils update their fees.

Estimates are indicative only and based on publicly available data. Actual costs vary based on site conditions, builder, and specifications.
