Why embed instead of link?

Higher engagement. Inline calculators convert ~3× better than "click to calculate" links.
Free for anyone. No license, no API key, no account needed. Just paste the iframe.
Always current. When we update the math, your embed updates automatically.
Mobile-responsive. Iframe scales width 100%; the calculator inside reflows for narrow screens.
