Margin formula (NZ worked example)
Extract GST (price × 15/115), then subtract costs. Margin % = Net profit ÷ price × 100.
🏄 Example: Outdoor / surf gear
At 8 sales/day that is about NZ$296/day or NZ$108,040/year before fixed costs — realistic for a focused niche store.
Local rules: NZ GST, fees & NZD
Currency: NZD. GST: Flat 15%, broad base, consumer prices GST-inclusive. Fees: Model Shopify Payments or Stripe % + fixed in the fee fields.
Geographic isolation raises shipping expectations — never leave postage at zero in your margin calculation.

Frequently Asked Questions
Real questions sellers ask about this calculator and local costs.
What is NZ GST and when do I register?+
NZ GST is a flat 15% on most goods and services. Register once taxable supplies exceed NZ$60,000 in any 12 months. Many sellers register earlier to claim GST on ads and inventory.
How does the NZ calculator handle GST?+
Retail prices must be GST-inclusive. We extract 15% GST from the listed price, then calculate profit on remaining net revenue after costs and fees.
What is a good profit margin in New Zealand?+
Target at least 25% net, with 35–50% ideal. The market is small (~5M people), so per-unit margin matters more than ultra-high volume.
Is Shopify popular in NZ?+
Yes. Shopify Payments is available with fees around 2.9% + NZ$0.30 on Basic (confirm current rates). Trade Me remains a major marketplace alongside DTC stores.
How do shipping costs affect NZ margins?+
NZ Post is common domestically; rates add up quickly. Always include tracked postage in the shipping field — underestimating postage is a frequent NZ margin error.
Can NZ sellers expand to Australia?+
Often yes via AU 3PLs. Recalculate shipping, FX, and tax — our Australia margin guide and this NZ tool help compare scenarios.
How do you calculate profit margin percentage in NZ?+
(Net profit ÷ selling price) × 100 after extracting GST and subtracting product, postage, ads, and fees. Defaults on this page walk through a realistic outdoor/surf example.
Is this free to use?+
Yes — free, no sign-up. Estimates only.
