Your calculator is
also a lead form.
Visitors already come to use a calculator, and that's real intent. Ask for an email before you reveal the result for the highest-intent leads, or after it so nobody bounces at a locked screen. Either way, every calculation becomes a qualified lead, and you know exactly what they were trying to figure out.

How it works
4 steps to your first lead
Pick a calculator
Choose any of our 2,400+ calculators relevant to your business, mortgage, ROI, cost savings, health goals, and more.
Choose before or after
Turn on lead capture in the embed customizer and pick whether the form appears before the result (gated) or after it (open).
Embed it on your site
Paste one snippet. The calculator, and the lead form, appear wherever you put it.
Collect leads in your dashboard
Every submission lands in Dashboard, then Leads, with the exact inputs and results they got, so you know what they were interested in.
One toggle, two modes
Before or after, your call
Every embed with lead capture turned on lets you pick where the form sits. There is no single right answer, so we built both.
Before the result
The result stays hidden until the visitor submits the form. Fewer leads, but every one of them genuinely wanted that specific number, so intent runs high. Available on our full standard calculator library.
After the result
The visitor sees their number right away, and the form sits underneath it as a plain invitation, not a gate. Nobody bounces at a paywall, so submissions run higher overall. Works on every calculator, including unit converters and other hub-style tools that before can't gate.

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.
Frequently asked questions
Before the result gets you higher-intent leads, since only visitors who genuinely want that specific number will submit. After the result converts more visitors overall, since nobody bounces at a locked screen, but the leads are a mix of intent levels. There's no universally correct answer: many site owners start with after and switch to before once they know their audience.
Name and email by default. Phone and company are also available as optional fields, for both the before and after form.
Straight to Dashboard, then Leads, along with the exact calculator inputs and results the visitor saw, so you know what they were actually interested in, not just a bare email address. You can also add a webhook URL to forward each new lead straight to your CRM or email tool automatically.
Analytics and embedding are included on every plan, including Free. Lead capture specifically is available from the Creator plan ($9.99/mo).
Yes, you're responsible for the content of any lead-capture form you configure and for complying with applicable law (such as consent requirements) on your own site, same as any form you'd build yourself.
Yes, as CSV, any time from Dashboard, then Leads.
Yes. Build and style a form once in Dashboard, then Lead Forms (headline, subtext, fields, button, and what happens after submit), then apply it to any embed. Edit it once and every embed using it updates automatically. Creator includes 1 saved form; Agency includes unlimited.
It works across our full standard calculator library. Hub-style unit converter pages currently only support the after-results form, since there's no single locked result to gate on a page with several fields updating live.
