Embed a calculator

Last updated: 2026-11-02

Most calculators and converters on kakaoCalc can be placed on your own website, blog or course page free of charge. The widget runs in your visitors' browsers, so the numbers they type are not sent to us or to you.

How to embed

1. Open the tool you want and find “Cite or embed this tool” under its explanation.
2. Copy the embed code: an iframe plus a text link to the tool's page.
3. Paste it into an HTML block on your page. Change the height attribute if your layout needs more or less room; the widget scrolls inside its frame if needed.

For example, the kg to lbs converter, the mortgage payment calculator and the percentage calculator all have embed code.

What the widget shows

• The tool's inputs and results, without ads, sign-up or tracking scripts.
• A short notice that the result is an estimate for general information, with a link to the full disclaimer.
• A link to the tool's own page, where the formula, a worked example and the sources are explained.

Conditions

• Embedding is free for personal, educational and commercial pages.
• Keep the widget's notice and links visible, and don't present its results as your own advice or as an official figure.
• Don't alter the results, and don't place the widget on pages that are unlawful or misleading.
• Tools can be updated or withdrawn. When a tax year or rate changes, the embedded tool shows the updated figures automatically.
• The disclaimer and the terms of use apply to embedded tools too.

Citing a result

The same box gives APA and MLA citations for the page, dated with the page's “Last updated” date. If you quote a figure in a report, note the inputs you used and the tax or rate year shown on the page.

Which tools can be embedded

Calculators that work from typed values, the unit converters, the currency converter and the time zone converter. File tools (PDF, image, audio and video) work only on kakaoCalc itself, because they need more memory and file access than a frame on another page should ask for.
