Calcula.

Free Calcula badge for your website

A simple, free way for Australian brokers, accountants, financial advisers and builders to give their clients access to accurate financial calculators — without the cost of building or licensing them. Pick a badge size, copy the snippet, paste it into your site.

Who this is for

Mortgage brokers

Help borrowers ballpark their borrowing capacity and stamp duty before the first call. Better-prepared clients, shorter discovery meetings.

Accountants

Give clients a quick income tax and HECS/HELP estimator to use ahead of EOFY conversations.

Financial advisers

Add a debt payoff and rent-vs-buy lens to your client portal or website resources page.

Builders & developers

Stamp duty and borrowing capacity calculators that help buyers understand the full cost of an off-the-plan purchase.

Pick a badge

All three badges are SVG so they look crisp on retina screens, are under 2KB each, and won’t slow your page down (the snippet uses loading="lazy"). A PNG fallback is available if your CMS doesn’t accept SVG — just swap .svg for .png in the snippet.

Link to a specific calculator

If a particular calculator is more relevant to your audience — say, a builder linking directly to the stamp duty tool, or a broker linking to the borrowing capacity calculator — just change the href in the snippet to the calculator URL. For example:

https://calcula.com.au/borrowing-capacity-calculator/?utm_source=partner&utm_medium=badge&utm_campaign=partner_badge

Available calculator URLs: /mortgage-calculator/, /borrowing-capacity-calculator/, /stamp-duty-calculator/, /tax-calculator/, /hecs-calculator/, /debt-payoff-calculator/, /rent-vs-buy-calculator/.

How to install the badge

The snippet is plain HTML — an <a> tag wrapping an <img>. It works in every CMS and on any custom-built website. The instructions below cover the most common platforms.

Not technical? If you can paste a YouTube embed code into your site, you can paste this. Same idea — just HTML.

WordPress — the most common option

In a post or page (Block editor):

  1. Edit the post or page where you want the badge.
  2. Click + to add a block, search for “Custom HTML”, click it.
  3. Paste the snippet into the block.
  4. Click “Preview” to confirm, then Update or Publish.

In the sidebar (most popular placement):

  1. Go to Appearance → Widgets.
  2. Drag a “Custom HTML” widget into the sidebar.
  3. Paste the snippet, then Save.
Squarespace
  1. Edit the page, click + to add a block, choose “Code”.
  2. Paste the snippet. Make sure “Display Source” is OFF.
  3. Save.
Wix
  1. Edit the page, then Add → Embed → Embed HTML.
  2. Paste the snippet, then click Update.
  3. Drag the element to position it where you want.
Webflow
  1. Add an “Embed” element to the page.
  2. Paste the snippet, click Save & Close.
  3. Publish.
Shopify
  1. Online Store → Themes → Customise.
  2. Add a “Custom HTML” section, or edit theme.liquid for a sitewide footer placement.
  3. Paste the snippet, then Save.
HubSpot CMS
  1. Edit the page, then Add module → “Rich text” or “HTML”.
  2. Paste the snippet.
Custom-coded HTML site
  1. Open the HTML file in your code editor.
  2. Paste the snippet wherever you want the badge to appear — inside a <div> in your sidebar, footer, or a “tools” section.
  3. Save and upload.
Email signature

The snippet works in most email clients too. Use the PNG version for email (swap .svg for .png in the snippet) because some clients block SVGs.

  • Gmail: Settings → Signature → paste the snippet (Gmail will render the image).
  • Outlook: File → Options → Mail → Signatures → paste in HTML mode.
  • Apple Mail: Mail → Settings → Signatures → paste the snippet.

Common gotchas to avoid

  • Paste into the HTML/Code block, not the Visual editor. Some platforms convert < and > into encoded characters in the visual editor and the badge won’t render. Always use the dedicated HTML or Code block.
  • Don’t override the badge size with custom CSS. The dimensions in the snippet are tuned for crispness on retina screens.
  • Don’t download the badge to your own server. Leave the src pointing to calcula.com.au/assets/…. That way, when we improve the artwork, your badge updates automatically.
  • Test after pasting. Click the badge on your live site to confirm it opens calcula.com.au in a new tab.

Terms — the short version

  1. Free for any legitimate Australian financial professional, business or content site. No registration, no fees, no contracts.
  2. Keep the link working. The badge must link to calcula.com.au (with or without UTM tags) and open in a new tab.
  3. Don’t modify the badge artwork. Use the SVG or PNG as supplied. Resize proportionally if needed.
  4. Don’t imply endorsement. Calcula does not endorse any specific broker, accountant or adviser. Don’t use the badge to suggest otherwise.
  5. We can update or replace the badge. Keep the snippet as-is and you’ll automatically receive any updates.
