Can you change the size or the language?
Yes. Change height in the code if the calculator is cut off or leaves a gap on your page; the heights above fit most layouts. The width follows your page up to 760 pixels. For the Spanish version, add ?lang=es to the end of the address, as in the codes on our Spanish page.
Is it really free?
Yes. There is no account, fee or sign-up. We only ask that you keep the small "Calculator by SuanSupply" credit inside the frame and the link under it, and don't present the calculator as your own tool.
Frequently asked questions
Is the embed free?
Yes. Copy the code and paste it into your page. No account, no fee and no sign-up.
Does it work on WordPress, Shopify, Wix or Squarespace?
It works in any editor that lets you add custom HTML or an embed code block, because it is a standard iframe.
Does the calculator send what visitors type anywhere?
No. The math runs in the visitor's browser and the numbers they type are not sent to us or to you.
Will the numbers stay up to date?
Yes. The frame loads the calculator from our site, so fee updates we make reach your page automatically.
Can I change the colors?
Not yet. The calculators use our standard look so they stay readable on any page.
The embedded calculators give estimates for planning. Fees they use are dated on each full calculator page.
