Why I built Calcupedia

Almost every site I've ever built needed some kind of calculator, and every time meant the same three bad options: hunt for a plugin, hire a dev for something a visitor uses once, or skip it. Calcupedia exists so nobody has to make that trade-off again. Pick a calculator, paste one line of code, done. I built the tool I wish existed for the last decade of building things on the internet.

Simple and Transparent Pricing

Every calculator is free to use, and free to embed on your own site. Upgrade when you need more embeds, lead capture, or full branding control.

Frequently asked questions

You have three real options: build it yourself with an AI tool like ChatGPT or Claude, which gives you code you still have to implement, test, and maintain; hire a web developer, which works but usually costs hundreds of dollars and takes days or weeks to finish; or pick from Calcupedia's library of free calculators and converters and paste one line of code, live on your site in under 60 seconds. For most site owners, Calcupedia ends up the fastest, cheapest, and easiest of the three.

Yes. Embeds work anywhere you can paste an iframe or script tag: WordPress, Webflow, Squarespace, Wix, Shopify, a hand-coded site, or a React/Next.js app. There's no plugin to install and nothing to keep updated.

No. Pick a calculator, customize it in a live preview, and copy one snippet. That's the whole process. If you can paste code into your site, you're done.

Yes. The embed customizer shows a live preview as you adjust colors, fields, and behavior, so you see exactly what visitors will see before you copy the code.

Describe what you need in a sentence, and Calcupedia's AI builder generates a working calculator for you, including inputs, formula, and results panel.

As many as you want. Growth is $1/mo per active embed; Creator and Agency include unlimited embeds in the flat monthly price.

You do. Lead capture is opt-in per embed, and every submission goes straight to your dashboard. Calcupedia never sells or reuses your visitors' data.

No. Lead capture is included in the Creator and Agency plans at no extra per-lead cost, unlike most embed tools that meter you per submission.

No. Anyone can use an embedded calculator with no signup. Only you, the site owner, need an account to create and manage it.

The embed loads in an iframe, so it never blocks your page's own content from rendering. Because it's an iframe, its content isn't crawled as part of your page, but the calculator already has its own indexed, SEO-optimized page on Calcupedia, so you're not losing anything by embedding instead of building your own.

Yes, on the Creator plan and above. Free and Growth embeds show a small "Powered by Calcupedia" badge; Creator removes it, and Agency adds full white-label branding.

Yes, on the Agency plan. You get client management, team member access, and white-label branding, so each client's embed can carry your (or their) brand, not Calcupedia's.

Your embeds keep working until the end of your current billing period, then automatically revert to the Free plan's limits: one active embed, Calcupedia branding on. Nothing gets deleted.
