Drop your pricing spreadsheet into ChatGPT and get a live calculator form in minutes. Your customer sees their estimate. You get the lead, with the math already done.
You never leave ChatGPT. Paste a spreadsheet, get a link, change anything by asking. Works in Claude too.
Whatever you already calculate in a spreadsheet, you can ship as a form.
Stop attaching the Excel ROI model to every prospect email. Stop building one-off quotes in spreadsheets.

Say "match my website" and ChatGPT restyles the whole form: colors, fonts, spacing, depth. No design work, no code, and you can undo it anytime.
FontsColorsSpacingDepthField styleDark modeAccent barButton textEvery style option is checked by us, so your form can look like your site and can never break. Try it: build your form and add “brand it like my website.”
When a customer submits, you don't get raw inputs to plug into your spreadsheet. You get the calculated result — subtotal, tax, total, payback, monthly payment, whatever your formulas compute — already done. Stop running the spreadsheet on every lead.
By default, every calculation stays private: only you see it. Choose which calculations the customer sees as they fill the form in.
Show them the total, monthly payment, or payback. Keep your margin, cost basis, and broker commission private. One toggle per field.
Bonus: when customers see the answer they're calculating, they convert at ~17× the rate of static contact forms (47.3% vs 2.8%, per Outgrow's 2025 benchmark of 50,000+ forms).
No drag-and-drop builder. No code. No second tool to learn.
One click on the CalcForms app page, then sign in with your email (we send a 6-digit code). A free ChatGPT account works.
Paste your spreadsheet, or just say "build me a quote calculator." ChatGPT builds the form and gives you a link.
Send the link to customers. They fill it in and see their number. Every reply lands in your dashboard with the math done. Want a change? Just ask: "make the discount 15%." Same link.
Here is exactly what you can do with CalcForms. No developer needed for any of it.
Describe the form or paste your spreadsheet. It's live in minutes.
Every formula in your sheet works the same way in the form.
Your pricing grid comes along, so the form looks up the right rate on its own.
Rooms, products, properties: customers add rows and the form adds them up.
Email it, text it, post it, or put a button on your site.
Send a personal link to one customer, and take it back whenever you like.
Half-finished? They get a link by email to pick up right where they left off.
They get a copy of what they sent. You get it with the math already done.
Say "raise the Office rate to $1.20" and the live form updates. Same link.
Ask about solar panels only if they own the roof.
Test the form with your own past quotes before it goes live.
Change one input on a past reply and see the new result.
Customers see their total. Your margin, cost basis and every other calculation stay private to you.
Each submission lands in your dashboard with all the calculations worked out.
