New Zealand GST calculator
Type an amount into any of the three boxes; the other two follow at the rate you pick.
GST = 100.00 × 15% = 15.00; gross = 100.00 + 15.00 = 115.00
Worked in whole cents: the tax is rounded to the nearest cent (half a cent goes up) and the other amount is the difference, so the boxes always add up. From a gross amount the tax is gross × rate ÷ (100 + rate); from a typed tax amount the net is worked back and your tax amount stays as typed. Your tax authority may set its own rounding rules for invoices.

Add GST: gross = net × (1 + rate ÷ 100). Extract GST: tax = gross × rate ÷ (100 + rate), and net = gross − tax.
| Rate | Tax share of a gross price | Net 100 → tax / gross | Net 1,000 → tax / gross | Gross 100 → tax / net | Gross 1,000 → tax / net |

How do I add GST to a net price?
Multiply the net amount by (1 + rate ÷ 100). At 15%, a net price of 100.00 becomes 115.00 gross, of which 15.00 is GST. The calculator on this page does it with New Zealand's verified rates preloaded.
How do I work out the GST included in a gross price?
