Important

This calculator uses New Zealand’s standard 15% GST rate and is a calculation aid only. Your GST registration and tax treatment depend on your circumstances.

The calculation is only useful when the customer can understand the quote

Use Tradient to turn your pricing into a clear scope, itemised quote, photos and one approval flow instead of sending a number with missing context.
