Free embeddable calculators for your website

Put a working calculator on your own page. Pick a widget, copy the code, paste it in. It is free, needs no signup, and shows no ads or tracking inside the widget.

1. Choose your widget

Bill, tip percentage and split between people, with a round-up option. Opens in dollars, pounds, Canadian dollars, Australian dollars, euros or rupees.

Visitors can still switch currency inside the widget.

2. Copy the code

The second line is a credit link to the calculator. Please keep it: it is the only payment for the widget, and it tells your readers where the tool comes from.

Preview

This is the live widget. The “Free tip calculator by MoreCalculators.com” line inside it links back to the full page.

How to add it

  1. Choose a widget and, where it applies, the currency it opens in.
  2. Copy the code. It is a frame, a one-line credit link and, optionally, a small script that resizes the frame.
  3. Paste it into an HTML block on your page (WordPress calls it “Custom HTML”; other builders say “HTML”, “Embed” or “Custom code”), then save and view the page.

The credit link under the frame is what makes the widget free. It points to the full calculator, which has the formulas, worked examples and sources, so your readers can check the maths. Please leave it in place.

Questions

Is it free?

Yes. There is no signup, no fee and no limit on how many pages or sites you use it on, including commercial sites. The only thing we ask is that you keep the credit link under the widget.

Does the widget show ads or track my visitors?

No ads and no analytics or tracking scripts load inside the widget. It is served from morecalculators.com, so our web server receives an ordinary request for it, as with any embedded content, and the widget remembers a chosen currency in the visitor’s own browser.

Will it work on my site?

It works on any page where you can paste HTML into an “HTML”, “Custom code” or “Embed” block, which covers most website builders and content systems. Some schools, companies and builders block iframes or scripts. If yours does, link to the full calculator page instead.

Can I change the colours or the size?

Pick light, dark or automatic in the builder. Add &bg=transparent to the frame address to let your page background show through. The frame is 100% wide up to 720 pixels; change the width and max-width in the code if you need something else.

What does the auto-resize script do?

It listens for the height the calculator reports and sets the frame to that height, so there is no scrollbar inside the frame. It only reacts to messages from the calculator frame and never reads anything from your page. If your site blocks scripts, untick the option and set a fixed height.

Do the widgets stay up to date?

Yes. The widget is loaded from our site each time, so a corrected formula or an updated rule (such as a stamp duty change) reaches your page without you touching the code.

Are the results financial advice?

No. They are estimates for information. Example interest rates and tax rates in the widgets are not offers or quotes, and the mortgage and tax rules are summaries of public rules, not advice for your situation.

Can I ask for another calculator?

Yes, tell us which one through the contact page. We add widgets based on what people ask for.
