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
- Shows live gross and net commission as the user enters sale price, rate and split tier
- Keeps your real brokerage logic: split tiers, annual cap, transaction fees and franchise royalty from your spreadsheet
- Captures each agent or seller as a lead with sale price and net commission already calculated
- Update split tiers, caps or fee schedules later just by asking ChatGPT
- Backtest against closed transactions so the net you show matches what agents actually banked
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.
Step-by-step: turn your spreadsheet into a form, add your price list, show customers one number. All guides →
"Build a commission calculator from my brokerage split workbook. Take sale price times commission rate for gross, apply the agent split tier from the Splits tab, stop the brokerage share once the agent hits the annual cap, then subtract the transaction fee and franchise royalty for net."
Example run: An agent enters a 525,000 dollar sale at 2.5 percent on an 80 percent split with a 395 dollar fee. The form shows about 10,105 dollars net after the split and fee, then sends you the lead with sale price and split 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.
