Who should pick which
Pick Outgrow if…
- You are building quizzes, assessments, and marketing funnels
- Design-heavy interactive content matters more than exact math
- You have a marketing team to maintain the builder
Pick CalcForms if…
- You sell something priced from a spreadsheet and want the quote to match it exactly
- You want a contractor, broker, or consultant to be able to build it alone
- You want unlimited forms free in ChatGPT and a web portal for $12.99 a month
The same in both: Both show the customer a calculated result. Both capture the lead with the result.

Questions about Outgrow vs CalcForms
I use Outgrow for ROI calculators and lead scoring. Can CalcForms do that?
Yes. ROI calculators, lead scoring formulas, pricing quizzes. If the math lives in a spreadsheet, CalcForms builds it. Results update as your customer types in list view, and every lead arrives already scored, in ChatGPT or in the web portal on Pro.
Is CalcForms cheaper than Outgrow?
Yes for most users. CalcForms is free in ChatGPT with unlimited forms and submissions, and the Pro web portal is $12.99 a month. Outgrow calculators start at $22 a month, or $14 a month billed yearly, for 5 content pieces; unlimited content is $115 a month, or $95 a month billed yearly.
Do I need to know how to use ChatGPT to build a form?
No. You describe the form in plain English or paste the spreadsheet. ChatGPT handles the build and hands you a live URL. Most forms are done in under 20 minutes.
Can my marketing team edit the form later?
One account edits each form. A form belongs to the CalcForms account that built it, and the person signed in to that account updates it by asking ChatGPT in plain English. No developer needed.
