Calculators
Calculators that show the number before they submit
A calculator is the rare form people want to fill in, because it gives them something back. CrispForms evaluates a formula over the answers as they're given, so the number is on screen before anyone presses submit — which is what makes them press submit.
Real formulas, safely evaluated
Arithmetic, comparisons, and conditionals, over the answers and variables by name. It's parsed and evaluated by our own engine — nothing you type becomes code that runs, which is why this can be offered to everyone.
The answer updates as they type
A calculated value block recomputes on every change. Someone adjusting their inputs and watching the number move is the entire experience of a good calculator.
Capture the email after the value, not before
Show the number first, then offer to send it. A calculator gated behind an email form is just a lead form wearing a hat, and it converts like one.
Every answer is still a response
The inputs and the calculated result are stored like any other answer, so you can export them, push them to a sheet, or send them to your CRM.
Start from a template
Each of these is a working form. Clone one and it's an editable draft in your workspace.

Income and outgoings in, a rough borrowing figure out.

Questions people ask
- What can the formulas do?
- Add, subtract, multiply, divide, compare, and branch with a conditional. They can reference any earlier question by its reference and any variable by name.
- Can I hide the calculation from the respondent?
- Yes — turn off 'display' on the calculated field and the value is stored with the response without being shown. Useful for lead scoring.
- Do I need to write code?
- No. A formula is a line of arithmetic typed into a field, the way you'd write it in a spreadsheet.
