Try it yourself
This is a real, working CalcForms calculator, right here on the page. Enter your details and watch the estimate update on the spot. It is exactly what your customers would use, and every submission lands in your dashboard as a lead.
What it calculates
- Prospects see a live retainer estimate the moment they pick channels and ad spend, so more of them book the call
- Keeps your exact Excel pricing model: per-channel rates, ad-spend percentage tiers, and minimum retainers
- Handles multi-tab workbooks where SEO, paid, and creative each price on their own sheet
- Update rate cards or add a service line later just by asking ChatGPT, no rebuild
- Backtest against your last 50 proposals so the calculator matches what you actually charged
Why it closes more deals
A live number closes deals
Customers who see a real estimate the second they enter their details are far likelier to book than ones told to call for a quote. The number is the hook.
Runs your most complex spreadsheet
Multi-tab workbooks, lookup tables, tiered rates, conditional line items, the lot. If the math runs in Excel, CalcForms runs it behind a clean form.
Update it by chatting
Prices move. Ask ChatGPT to change a rate, add an option, or insert a step and the live form updates in seconds. No developer, no redeploy.
Backtest before you publish
Run your last 20 real jobs through it and tune the formula until the live estimate matches what you actually charge. Ship it once it lines up.

How this form was built
No template builder and no code. One message to ChatGPT with CalcForms added:
Build this exact form
CalcForms is an app you add to ChatGPT once. After that you build and edit forms just by chatting. Works in Claude too.
- Add CalcForms to ChatGPT. Open the CalcForms app page, click Add, and sign in with your email. One time, about 60 seconds. A free ChatGPT account works. (Using Claude? Setup here.)
- Say the words below. ChatGPT builds the form with your math inside and gives you a link.
- Share it, then change it by asking. Send the link to customers. Change a rate or add a question later just by asking.

"Here is my agency rate card spreadsheet. SEO is a flat tier, paid media is 15% of ad spend with a $2,500 minimum, and content is priced per piece. Build me a pricing calculator where prospects pick services and get a monthly retainer, with a 12-month discount of 10%."
Example run: A SaaS founder picks full-funnel, $20k-$50k ad spend, 8 blog posts, 3 paid channels, and a 12-month term. The calculator returns roughly $9,400/month after the annual discount and routes the lead to the agency with every input attached.
How does it work? CalcForms is an official ChatGPT app. Once it is added, ChatGPT can build, publish and update real calculator forms for you, all from the chat window. Your customers never need ChatGPT; they just open a link.
