Enter the net (ex-GST) price to get the GST-inclusive total.
Most goods and services — standard IRD rate
GST registration generally applies from $60,000 turnover in a 12-month period (IRD). This calculator models a single price line — not your GST return.
Gross total (incl. GST)
15% GST$287.50
$250.00 × 15% = $37.50 GST.
Add or remove GST for invoices, quotes, and receipts.
The GST amount and total (or ex-GST price) above come from the amount, add/remove mode, and supply type you enter — not a live IRD feed. The standard rate and registration threshold match published IRD guidance. Below are the formulas, steps, and worked examples from the same engine as the live calculator.
Worked example — add 15%
Add 15% GST — $250.00 net
| Mode | Add GST |
| Net amount | $250.00 |
| Rate | 15% |
| GST | $37.50 |
| Inclusive total | $287.50 |
$250.00 × 15% = $37.50 GST → $287.50 inclusive
Worked example — remove 15%
Remove 15% GST — $287.50 inclusive
| Mode | Remove GST |
| Gross (incl. GST) | $287.50 |
| Rate | 15% |
| Net (ex-GST) | $250.00 |
| GST embedded | $37.50 |
$287.50 ÷ 1.15 = $250.00 net; GST = $37.50 (also 3/23)
Zero-rated education mode (0%)
Zero-rated education mode: GST $0.00, total $250.00
Formulas
- Add GST — GST amount: GST = Net price × (15 ÷ 100)
- Add GST — inclusive total: Total with GST = Net + GST
- Remove GST — ex-GST price: Net = Gross ÷ (1 + 15 ÷ 100)
- Remove GST — GST embedded: GST = Gross − Net
- 3/23 shortcut (standard rate): GST embedded = Gross × (3 ÷ 23)
- Rounding: All NZD amounts rounded to the nearest cent (2 decimal places)
Calculation steps
- Confirm the supply typeStandard 15% · Zero-rated 0% · Exempt 0%
Most goods and services are standard-rated at 15%. Zero-rated and exempt supplies use 0% in this tool for education — they are not invented reduced rates. Exempt supplies usually restrict input tax credits.
- Choose add or remove modeAdd: amount is ex-GST · Remove: amount includes GST
Add mode prices a net figure up to a customer total. Remove mode backs GST out of an invoice or receipt gross.
- Add GSTGST = Amount × Rate; Total = Amount + GST
Multiply the net price by the rate, then add GST to get the inclusive total.
- Remove GSTNet = Gross ÷ (1 + Rate); GST = Gross − Net
At the standard rate, GST is also 3/23 of the GST-inclusive price (IRD).
- Round to centsround(value, 2) — half-up to 2 decimals
Matches typical invoice rounding. Tiny differences can appear if you add then remove on odd amounts.

This is the usual calculation for standard-rated goods and services sold by a GST-registered business. On an invoice, list net, GST, and total separately.

Zero-rated is not automatic for “cheap” or “essential” items — only qualifying categories under IRD rules.
Exempt vs $250 at standard rate
An exempt supply at $250 net has $0.00 GST. Compared with standard-rated, the customer saves $37.50 on this line.
Exempt sales usually restrict input tax credits — confirm on IRD exempt guidance before assuming 0% treatment.
Working backwards from a GST-inclusive total
If a receipt shows $287.50 including 15% GST, the net is $250.00.
Use remove mode whenever the amount you see already includes GST. The standard-rate shortcut is inclusive × 3/23.
When this amount shows up in real life
$250 is a common quote, deposit, or line-item size for freelancers and small traders. Model it ex-GST first if you are (or expect to be) GST-registered, then add the correct treatment.
Registration is about turnover across a 12-month period (threshold $60,000), not whether a single invoice equals $250.
Checklist
- Verify $250 is the net (ex-GST) figure before adding GST.
- Pick standard-rated vs zero-rated vs exempt based on the supply, not the amount.
- Round to the nearest cent on invoices.
- Do not add GST again if the figure already includes GST — use remove mode.
- Keep the calculation for your records if you are GST-registered.
