FAQ
How do I add a calculator to my website?
Open any calculator, copy the embed code at the bottom of the page and paste it into your site's HTML. It works on WordPress, Wix, Squarespace, Webflow and Shopify.
Is it free?
Yes. All 20 calculators can be embedded free with a “Powered by CalcPane” link. Paid plans remove branding.
Can I match my brand colours?
Yes, on Pro ($9/month) and Business ($29/month).
Can the calculator capture leads?
Yes, on the Business plan: submissions are emailed to you and downloadable as CSV from your dashboard.
Can I preset my own rates?
Yes, on Business you can set default values for every calculator in your dashboard.
Will it slow my site down?
No. Embeds are lazy-loaded and use one small CSS and JS file with no frameworks or third-party trackers.
