Why GST math matters
Business owners, freelancers, and shoppers all deal with GST. Getting the split right keeps your invoices correct and your records clean. This tool shows both the tax part and the total, so billing is simple and clear.
Add or remove GST
Sometimes you know the price before tax and need to add GST. Other times you have the final amount and need to find the tax already inside it. The calculator handles both ways so you always get the right figure.
