# How We Calculate

Learn about our unit-rate landscape estimation algorithms and how BackyardCost calculates precise Australian backyard remodel quotes.

While our component algorithms are highly sophisticated, they are designed to provide a realistic planning estimate. The final quotes from local licensed landscapers may vary based on soil composition (e.g. hitting heavy sandstone or rock during excavation), localized design elements, specific timber selections, and seasonal builder demand.

Always obtain multiple comparative quotes before purchasing materials. Learn more about where we source our core numbers by checking our data sources.
