Embed a calculator on your site

Every sizing calculator on GeneratorMath can be dropped into your own page with a single iframe. No JavaScript, no sign-up, no tracking scripts, and no ads — the embed never loads any. It is the same calculator and the same sourced data as our own pages — the same manufacturer-verified wattages — so it stays correct when we update them.

Terms

Free to embed — including on sites that carry ads or affiliate links.
The “Calculator by GeneratorMath” link must stay visible and clickable. That link is the entire price.
Please don’t resell the embed or republish the underlying data tables as your own.
Need a different size, or a calculator we haven’t built yet? Get in touch.

Sizing note: the box below is 420×680, which fits most results without scrolling. Make it taller if your calculator has many inputs — the embed scrolls internally rather than clipping, so nothing is ever hidden.
