What is Payment split calculator?

Payment split calculator is one of 590+ free widgets on PlanckUi. Split a bill by percentage, not by heads.. Small interactive utilities give visitors a reason to stay, return and bookmark you.

Perfect for sidebars, tool pages and resource collections.

Everything is rendered in an isolated shadow DOM, so it can never conflict with your site's own styles — and at a few kilobytes, it won't move your page speed.

Frequently asked questions

Is Payment split calculator really free?
Yes — completely. PlanckUi widgets are free forever, with no watermark, no usage limits and no credit card. Paid widget platforms charge $15–40 per month for the same embeds.
Do I need an account to use Payment split calculator?
No. Click "Copy HTML" and paste it on your site — that's the whole flow. An account is only needed if you want to collect live data (like customer testimonials) and manage it from a workspace.
Does it work on Wix, Squarespace, Webflow, WordPress or Shopify?
Yes. If a platform lets you paste an HTML embed block — and all of them do — Payment split calculator works there. The snippet is plain HTML and CSS in an isolated shadow root, so it can't fight with your theme.
Will Payment split calculator slow down my website?
No. The widget is a few kilobytes of HTML and CSS rendered locally in your browser — no external requests, no tracking scripts, no layout shift.
