--- title: "NZ Tip Calculator: Tips Are Optional, Start at 0% | AumnI tools" description: "Enter a bill in New Zealand dollars to see what a tip of 0% to 20% adds, with the tool opening at no tip and buttons for 5%, 10% and 15% if you choose to give one." url: https://aumnitools.com/nz/tool/tip-calculator category: "Financial" country: "New Zealand" updated: 2026-11-08 --- # Tip Calculator New Zealand does not expect a tip, so this version opens at 0% and the total equals the bill. If you want to reward good service, the buttons add 5%, 10% or 15%, and the slider reaches 20%. GST at 15% is already in every price, and you can enter it to tip on the amount before tax. ## New Zealand rules and figures - Tourism New Zealand says tipping is not obligatory, even in restaurants and bars. - Tipping for good service or kindness is at your discretion. - Tourism New Zealand gives no tipping percentage, so any figure here is a tool suggestion. - Service charges are not added by hotels and restaurants. - GST is 15% and is included in shelf prices.

Choosing a percentage adds a tip to the subtotal, which is the bill less any GST amount you enter, and the total is the bill plus the tip. Formula: `GST inside a price = price × 15 ÷ 115; tip = (bill − GST) × tip% ÷ 100; total = bill + tip` - The default is 0%, which makes the Poor rating (one star) the starting point. - The buttons are 5%, 10% and 15%, and Tourism New Zealand gives no percentage, so they are only suggestions. - With no service charge on the bill, there is nothing to remove before you tip. - The tax box takes the GST amount if you want the tip based on the pre-GST subtotal. - Round Up lifts a tip to the next whole dollar, so a $5.00 tip stays as it is. ## How to use the tip calculator 1. **Enter the bill and tax.** Type the total on the check. If the tip should exclude tax, type the tax line too and the tip is taken from the pre-tax subtotal. 2. **Choose a currency.** Pick the currency whose symbol and decimals you want on the results. It starts as the country's own currency. 3. **Pick the tip percentage.** Click a star rating, use a preset or the slider, or type a percentage and press Apply. 4. **Round the tip if you like.** Switch on Round Up to lift the tip to the next whole currency unit. 5. **Copy or keep the numbers.** Copy any figure with its button, download the receipt, or save the calculation to the history list. ## Example: A $115.00 bill with $15.00 of GST GST at 15% inside $115.00 is $15.00, which leaves a subtotal of $100.00. At the opening 0% the tip is $0.00 and the total stays $115.00. Choosing 5% adds $5.00 for $120.00, 10% adds $10.00 for $125.00, and 15% adds $15.00 for $130.00. ## When to use the tip calculator - **Seeing the no-tip total.** Type the bill and read the total at 0%, which is the normal outcome for a meal in New Zealand. - **Rewarding unusually good service.** Press 5% or 10% and read how much that adds before you pay. - **Tipping before GST.** Enter the GST figure from an invoice so the percentage applies to the price without tax. - **Rounding up a small tip.** Switch on Round Up to hand over a whole-dollar amount rather than coins. ## What the tip calculator does not do - Zero is the opening value, and the Apply box ignores 0, so the slider is the way back to no tip. - The buttons are suggestions from this tool, because no official percentage exists. - GST is not calculated for you; only the amount you type is taken out of the tip base. - No currency conversion happens, so a visitor still enters amounts in the currency printed on the bill. - Saved entries are kept in memory and disappear when the page reloads. ## When something else is a better fit - **When you are dividing the bill among friends**, use the [Tip and Bill Splitter](https://aumnitools.com/tool/tip-and-bill-splitter.md). - **When you want the GST out of a shop price**, use the [Discount Calculator](https://aumnitools.com/tool/discount-calculator.md). - **When you are a visitor planning costs**, use the Tourism New Zealand guide to currency and costs. ## Questions about the tip calculator ### Should I tip in New Zealand? Tourism New Zealand says tipping is not obligatory, even in restaurants and bars. A tip for good service or kindness is your choice. ### Why does the calculator start at 0%? Because no tip is the normal outcome. The total equals the bill until you pick a button or move the slider. ### Is a service charge added to New Zealand bills? No. Hotels and restaurants leave service charges off, so the total is the price plus whatever tip you add. ### How is GST handled? GST is 15% and included in prices. On $115.00 the GST is $15.00, and entering it makes a 10% tip $10.00 rather than $11.50. ### What percentages should I use? There is no official figure. The buttons at 5%, 10% and 15% are only a guide, and the slider goes up to 20%. ## Related tools - [Tip and Bill Splitter](https://aumnitools.com/tool/tip-and-bill-splitter.md): Split a bill and tip evenly across diners, with a comparison of five tip levels - [Percentage Calculator](https://aumnitools.com/tool/percentage-calculator.md): Eight percentage questions solved from two numbers, with each step shown - [Currency Converter](https://aumnitools.com/tool/currency-converter.md): Converts 14 currencies, Bitcoin and Ethereum at daily rates, with a fallback table ## About this page Runs in your browser: what you enter is processed on this device and is not uploaded.
