A GST calculator is a tool that helps you calculate goods and tax (GST) for your products or services. If you’re registered for GST, you have to include GST on your invoices, unless you sell zero-rated or exempt items.
The calculator helps you work out the price including or excluding GST, and to comply with the rules and regulations in New Zealand.
Add GST to the price
To figure out the total price with GST, simply multiply the original price by 1.15.
$100 x 1.15 = $115
Work out the GST amount to add
To figure out how much GST you’ll be charging, simply multiply the original price by 0.15.
$100 x 0.15 = $15
Exclude GST from the price
If you want the price without GST, divide by 1.15.
$115 / 1.15 = $100
Work out the GST amount that was added
To figure out how much GST was included in the price you can take the price with GST minus the price without GST.
$115 – $100 = $15
| Price excluding GST | GST amount | Price including GST |
|---|---|---|
| $100 | $15 | $115 |
| $200 | $30 | $230 |
| $300 | $45 | $345 |
| $400 | $60 | $460 |
| $500 | $75 | $575 |
| $600 | $90 | $690 |
| $700 | $105 | $805 |
