Embeddable Paycheck Calculator Widget
Add a free, accurate paycheck calculator to your website in one line. Pick a calculator and theme, copy the snippet, and paste it into your page.
How to add it to your site
- Pick the calculator and theme you want above.
- Click "Copy embed code" to copy the snippet.
- Paste it into your page's HTML where you want the calculator to appear. Keep the "by paycheck.tools" link: it is required for the free embed. The script tag is optional: it auto-resizes the frame to fit the result, and the embed still works without it.
The widget is a self-contained iframe: it calculates server-side, works without JavaScript, and updates itself as our tax data is refreshed each year. You never touch the code again. The snippet also drops a small script that resizes the frame to fit its result, with a fixed-height fallback when scripts are blocked.
The visible "by paycheck.tools" link sits outside the iframe on purpose: it is the credit that lets your readers (and search engines) find the full calculator. Embedding is free: no account, no API key, and no usage limits.
Frequently asked questions
Is embedding the calculator free?
Yes. There is no account, API key, or usage limit. Copy the snippet and paste it into your site. We only ask that you keep the visible "by paycheck.tools" credit link.
Will the embedded calculator stay accurate?
Yes. The calculator runs on our server and reads the same year-versioned tax data as the full site, so it updates automatically when rates change. You never edit the embed.
Does it work if my visitors have JavaScript disabled?
Yes. The calculator computes server-side and submits a normal form, so it works without JavaScript. The optional script only auto-resizes the frame to fit the result.
Can I match my site's colors?
You can pick a light, dark, or automatic theme that follows each visitor's system setting. Full white-label styling is planned for a future version.
