Free subscription calculator for your website
Put the SubCrisp subscription calculator inside your own article or page. It is free for any site, including commercial ones, takes one paste, and your readers can use it without signing up.
No cookies, no tracking, nothing collected: a reader’s list stays in their own browser.
Get the embed code
Choose a width and theme, copy the code, and paste it into your page. The preview below is the real widget.
Each reader starts on their own currency, guessed from their browser, and can change it.
<div id="subcrisp-calculator" data-theme="auto">
<a href="https://subcrisp.com/subscription-calculator">Subscription calculator by SubCrisp</a>
</div>
<script src="https://subcrisp.com/embed.js" async></script>Works down to 320px wide. A site with a strict Content-Security-Policy needs to allow scripts and frames from subcrisp.com.

Why it is safe to put on your site
No cookies, no consent banner
The widget sets no cookies and collects nothing, so it adds nothing to your cookie notice.
Your readers’ data stays theirs
Their list and prices are kept in their own browser. We never see them.
Does not slow your page
It loads lazily in a frame, after your article, and sizes itself to its content.
Fits your site and your readers
Light, dark or matching the reader’s system theme, down to 320px wide, and in each reader’s own currency or one you set.
How to add it to your site
Copy the code above, then paste it wherever your platform accepts raw HTML. The calculator appears where you paste it.
- WordPress
- Add a Custom HTML block where the calculator should go and paste the code.
- Squarespace
- Add a Code block, set it to HTML and paste the code.
- Webflow
- Drag an Embed element onto the page and paste the code.
- Wix
- Add Embed Code, choose Embed HTML, paste the code and set the box tall enough to fit.
- Ghost
- Insert an HTML card in the post and paste the code.
- Any HTML page
- Paste the code into the page’s HTML where the calculator should appear.
Platforms that strip scripts from posts, such as WordPress.com free plans, Medium and Substack, cannot run it.
Keep the credit visible
The widget carries its own small SubCrisp credit. Please do not hide or cover it: that is the one condition, set out in our terms. The link in the code is a thank-you we would appreciate you keeping, but it is not required, and you are free to mark it nofollow.
Questions from site owners
Is the calculator widget really free?
Yes, on any site, including commercial ones, with no account and no limit. The only condition is that the small credit inside the widget stays visible.
Will it slow my page down?
No. The script is small, loads after your page, and the calculator itself loads lazily in a frame, so it does not hold up your article.
Do I need a cookie banner for it?
Not for the widget. It sets no cookies and collects nothing, and a reader’s list never leaves their browser.
Can I change how it looks?
Pick light, dark or automatic (follows the reader’s system) and a width when you copy the code. The calculator adapts to narrow columns down to 320px.
Can I remove the SubCrisp link?
Yes. The link in the code is optional, and you can mark it nofollow if your site does that for outside links. We would appreciate you keeping it. The credit inside the widget stays either way, and that one must not be hidden, as our terms say.
Does it work outside the UK?
Yes. Each reader sees their own currency, guessed from their browser and changeable in one tap, from the 87 the SubCrisp app supports. If your audience is in one country, fix the currency for everyone when you copy the code.
Does it work on phones?
Yes. It is the same calculator as on our own page, built for touch, and it resizes as readers add subscriptions so it never scrolls inside itself.
