Free Widget
Add a take-home pay calculator to your site
Two steps and about a minute. It is free, there is no sign-up, and we keep the tax rates current so it never goes out of date.
Pick a calculator, then copy the code
Paste it where you want the calculator
Anywhere in your page works. Most people put it on a salary guide, a job advert template, or a pay and benefits page. Find your platform:
WordPress
Edit the page, click the + to add a block, search for Custom HTML, and paste the code into it. Update the page. If you use the Classic editor instead, switch from Visual to Text first, then paste.
Squarespace
Edit the page, click an insert point, choose Code from the block menu, and paste the code in. Make sure the block's mode is set to HTML, then save.
Wix
Click Add, then Embed & Social, then Embed HTML. Choose Code, paste, and click Apply. Drag the box to the size you want.
Webflow
Drag an Embed element onto the page, paste the code into it, and save. It renders on publish rather than in the designer.
HubSpot, Shopify or a plain HTML site
Paste it straight into the page's HTML wherever you want it to appear. It is a standard iframe, so nothing else is needed.
Somewhere else, or it is not working
Look for a block or module called Embed, Custom HTML, Code or Raw HTML. If your platform strips iframes, or you would rather we hosted it differently, email us and we will sort it.
That is it
Nothing else to configure. When tax rates change we update the calculator and every site running it updates automatically, so the code you pasted never needs touching.
The one thing we ask
Please keep the Powered by CompoundMoney.co.uk line that comes after the iframe. It is deliberately outside the frame rather than inside it, because anything inside an iframe belongs to our page and does nothing for either of us. A plain link in your own HTML is visible to your readers and to search engines, and that is the trade: you get a tool you did not have to build and never have to maintain, we get the credit.
Beyond that, use it on as many pages as you like, commercially or otherwise.
Who it is for
Show candidates what a salary is actually worth each month, right next to the advert. Fewer offers lost to pay confusion.
Give clients a self-serve answer to the question you field every week, without building anything.
Let employees model a pension change or a pay rise before they email you about it.
Blogs, forums, comparison sites, university careers pages. If your readers earn a salary, it fits.
What it calculates
Income tax, National Insurance, pension salary sacrifice as a percentage of gross, and all six student loan plans, for the 2026/27 tax year in England, Wales and Northern Ireland. The figures match our full take-home pay calculator, and nothing your visitors type is sent anywhere: the maths runs entirely in their browser.
Questions
Is it really free?
Yes, with no catch and no sign-up. We ask only that you keep the credit link. It is how a small site gets discovered.
Will it slow my page down?
No. It loads lazily, it is a few kilobytes, and it is served from Cloudflare's network.
Does it collect data on my visitors?
No cookies and nothing stored on their device. We count page views on our own servers without recording IP addresses, so there is no consent banner for you to worry about.
Can I change how it looks?
Width and height, yes, by editing those values in the code. If you need it to match your brand more closely, tell us what you need.
Does it cover Scotland?
Not yet. Scotland sets its own income tax bands. The widget uses England, Wales and Northern Ireland rates and says so on its face.
Can I use it on a client site?
Yes, including commercial and client-facing sites, as long as the credit line stays.
