ROI calculator form built inside Claude

An ROI calculator form built with CalcForms takes a prospect's inputs (current spend, headcount, time spent on a problem) and returns annual savings, payback period, and 3-year ROI. You build it inside Claude by describing the model. Prospects fill it out on your site. The calculated answer lands in your dashboard so you don't run the spreadsheet on every lead. Free first form, $49/month after.

What it does

How you would build it

Your prompt to Claude

"Build an ROI calculator. Inputs: number of employees, hours spent per week on the problem, hourly cost. Calculate annual cost, projected annual savings at 60% reduction, and payback period in months. Show savings live to the prospect."

A 200-employee company spending 4 hours per week per person on the problem at $45 per hour gives $1.87M annual cost and $1.12M savings, with payback in 2 months.

FAQ

Can the form qualify the lead first?
Yes. Add a conditional: if company size or budget is below threshold, route to a contact form instead. Claude writes the logic when you ask.
Can I A/B test different assumptions?
Build two versions of the form, share both URLs, watch which gets more submissions. CalcForms creates each in seconds.
Can the prospect download a PDF of their result?
On the roadmap. Today the result lands in your dashboard and you can email a recap from there.
Is the math visible to the prospect or hidden?
You choose per field. Show them the savings number, keep your internal cost assumptions private.
