A calculator builder for your website.

A website calculator lets visitors enter their own numbers and see a result, such as a price, a saving or a return on investment. LeadsOnSite lets you build ROI, price and savings calculators with live formulas that update as people type, and capture each person as a lead.

What you can build

Calculators update while people type, with currency and percentage formats.

Turn results into leads

A calculator works like any other widget, so the follow-up and tracking come with it.

Common questions

What is a website calculator?

A website calculator is an interactive tool on a page where visitors enter their own numbers and get a result, such as a price estimate, a saving or a return on investment.

Do the results update live?

Yes. Formulas recalculate while people type, and results can be shown in currency or percentage formats.

Do I need a developer to build one?

No. You build it in a drag-and-drop builder and publish it from the dashboard. One script is added to your site once.

Can I add it to WordPress or Shopify?

Yes. It works on any platform that lets you add code to the head of your pages, including WordPress, Shopify, Webflow, Wix and Google Tag Manager.

Build your first calculator.

What do you want more of?

Step 1 of 2. This is a multi-step form, and the button you pressed is a floating button.

Get the 12-point popup checklist

This popup opened on a click. On your site it could open after a delay, at a scroll depth, or when someone heads for the tab bar.

Demo only. Nothing is sent.

Leaving already?

Your pointer just headed for the tab bar, so this exit-intent popup opened. It shows once per visit. On your site it is the last chance to keep someone who was about to go.
