Add any of our 111 free finance calculators to your website with one copy-paste. No signup, no API key, no code to maintain — the widget sizes itself to fit and updates automatically when we improve the calculator.
Browse all calculatorsChoose from 111 free calculators — mortgage, tax, retirement, budgeting and more. Each one has an embed slug, shown on its card below.
One script tag, with the calculator slug and your choice of light or dark theme. Swap the slug to embed a different calculator.
Paste the snippet anywhere in your page HTML. The widget appears in place, sizes itself to its content, and carries a “Powered by DailyFinance.tools” link.
<script src="https://www.dailyfinance.tools/embed.js"
data-calculator="mortgage-payment-calculator"
data-theme="light"></script>The iframe auto-sizes: the widget reports its exact height as it changes, so there is never blank space under it. A fixed height is available with data-height if you prefer one.
Each card links to the full calculator on this site. The slug under each title is the value for data-calculator.

There is no account to create and no key to manage. Copy the snippet and it works.
When we fix a formula or update a tax bracket, the widget on your site updates with it. Nothing to reinstall.
WordPress, Shopify, plain HTML — any page that accepts a script tag can host a widget.
The calculator runs on our servers. You never host code, patch dependencies or fix a broken widget.
No. Every embeddable calculator is free, with no signup, no API key and no usage limit. The widget carries a small "Powered by DailyFinance.tools" link — that is the only condition.
The loader is a small script that inserts a single iframe, loaded lazily so it does not block your page. The calculator itself runs on our servers, not yours.
Yes. Set data-theme to "light" or "dark" on the script tag. The widget follows that theme; there are no other style options on the free embed.
No extra credit is needed. Every embedded calculator includes a "Powered by DailyFinance.tools" attribution bar with a link to the full calculator, built in by design.
The free embed carries DailyFinance.tools branding. If you want a version styled for your own site, contact us and tell us what you need.
