Common questions
What others asks before signing up?
How do I calculate GST in Australia?
To add GST, multiply the GST-exclusive amount by 1.1. To find the GST component of a GST-inclusive amount, divide by 11. The Australian GST rate is 10%, set by the ATO. This calculator does both calculations instantly.
How do I remove GST from a price?
Divide the GST-inclusive price by 11 to get the GST amount, or divide by 1.1 to get the GST-exclusive price. For example, a $110 GST-inclusive item contains $10 GST and $100 excluding GST.
When do I need to register for GST?
You must register for GST if your annual turnover is $75,000 or more ($150,000 for not-for-profits). You can voluntarily register below this threshold. Once registered, you must lodge Business Activity Statements (BAS) and charge GST on taxable supplies.
How accurate is this GST calculator?
This calculator applies the exact 10% GST rate mandated by the ATO. It handles both adding and removing GST with precision. Note that some goods and services are GST-free — an accountant can advise on which items attract GST.
Can I add this calculator to my WordPress, Webflow, Squarespace, Wix or Shopify site?
Yes. Copy a single embed code from your Leadkit dashboard and paste it into any page. The calculator inherits your practice branding and optionally captures leads.
What do I get when someone fills out the calculator?
You receive an email notification with the visitor's contact details and their GST calculation — a warm lead who may need BAS lodgement, GST registration or ongoing accounting support.
What if I don't have a website?
Leadkit auto-generates a branded calculator page at a unique URL you can share on social media, in emails or on your Google Business profile.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How this GST calculator is calculated
This calculator applies the standard Australian GST rate of 10% as set by the Australian Taxation Office. It is a calculation tool only and does not constitute tax advice.
GST handling: The Australian GST rate is 10%, applied to most goods and services. Some items are GST-free (e.g. basic food, health services, education). Consult the ATO or a registered accountant for classification guidance.
1
Choose add or remove
Select whether you want to add GST to a GST-exclusive amount, or extract the GST from a GST-inclusive amount.
2
Calculate GST component
To add GST, the amount is multiplied by 0.10. To remove GST, the inclusive amount is divided by 1.1 to find the exclusive amount, and the difference is the GST.
