Describe It, and AI Writes the Formula

Tell WPForms AI what you want to calculate, in plain English, and it generates the formula for you.

You can review and edit every formula before publishing, so the AI hands you a starting point, not a black box.

Show Instant Results That Keep Visitors on Your Site

Static pages make visitors leave to do the math somewhere else. Your calculator shows results that recalculate the moment users change an input, so they stay, experiment with the numbers, and build trust in your expertise while they do it.

You can create virtually any calculator with WPForms: quote and estimate calculators, mortgage and loan calculators, BMI and calorie calculators, pricing and discount calculators, booking cost estimators, and self-scoring assessments. You can also add calculations to order forms, payment forms, and any other form you already run.

Do I need coding experience to build a calculator?

No coding experience is required. The WPForms drag-and-drop builder handles the layout, and formulas use a friendly spreadsheet-style syntax with a built-in cheatsheet. If you’d rather not write formulas at all, the AI formula generator writes them from a plain-English description.

Can I capture leads with a calculator?

Yes, every calculator built with WPForms is fully responsive. Inputs, sliders, and live results all scale to phones and tablets automatically, with no extra setup required.

Can I use calculations in order and payment forms?
