Pick a formula, decide which numbers your reader controls, and embed the result on your site. No code, and the constants can stay current on their own.
What your reader sees, and what keeps it accurate after you publish.
Start from a tested formula across ROI, cost, growth, and conversion, or write your own expression and watch it validate as you type.
Readers move a slider and the outputs recompute in the browser, instantly, with no page reload and no round trip to a server.
Bind a constant to a tracked claim instead of hardcoding it. When the underlying number changes, every widget using it changes too.
Copy one snippet into your CMS. The widget renders inline, sizes itself to the space, and stays fully interactive on your page.
Choose a starter calculator and the preview fills in with a working widget: formula, labels, units, and controls already set.
Change the formula, then decide what each variable is: a slider or number field your reader controls, a fixed value, or a constant bound to a tracked claim.
Publish to get a public URL and an embed code. Paste it into your post and readers start calculating.
