This GST calculator helps New Zealand business owners, sole traders and bookkeepers work out GST on any amount without reaching for a spreadsheet. Switch between adding GST to a GST-exclusive figure, removing GST from a GST-inclusive figure, or pulling out just the GST amount for a quick check mid-invoice. Every result updates live as you type, so there is nothing to submit and nothing to wait for.
By default this NZ GST calculator uses the standard 15% rate. If you work in accommodation, there is a separate option for the 9% rate that applies to hotels, motels and serviced apartments once a guest's stay passes 28 days: tick the box and the calculator switches its formula automatically.
This tool is meant for quick reference, not as a substitute for advice. If your GST position is more complex, or you are not sure which rate or treatment applies, get in touch with PAS and we will talk it through with you.
