Cost Calculator & Price Quote Form Builder
Build unlimited cost calculators, price estimators and quote forms with a drag-and-drop builder. 100% free — every feature, no paywall.
Most calculator plugins give you a few fields free and lock everything useful — conditional logic, multi-step forms, discounts, spam protection — behind a paid upgrade. RGT Quote Builder is different: every feature is free, forever. We don’t paywall your calculator.

This live mortgage calculator was built with the plugin — drag-and-drop, no code.
Everything’s included — free
Drag-and-drop layout
Arrange fields into rows and columns. Drop an element beside another for a column, or between rows for a new row. Resize any field: full, ½, ⅓ or ¼.
Formula engine
Write custom pricing with + − × ÷, brackets and functions like round, min, max, pow and if(). Live totals as visitors type.
Conditional logic
Show or hide any field based on what the visitor selects — no upgrade required.
Multi-step forms
Split long forms into steps with a progress indicator and Back/Next navigation.
Discounts & promo codes
Add automatic discounts or codes the visitor enters, with live recalculation.
Quote forms + email
Collect the visitor’s details and email the quote to you — and optionally to them.
Spam protection
Google reCAPTCHA (v2 & v3), hCaptcha or Cloudflare Turnstile. Add your keys and drop a captcha onto any form.
100+ templates
Loan, mortgage, BMI, tip, service quote, moving cost, wedding cost and dozens more — one click to start.
Fast & private
Scripts load only where a calculator exists. No bloat, no tracking, no external calls.
Questions
Is it really free?
Yes. Every element and every feature is free, with no upgrade wall and no limits.
How do I add a calculator to a page?
Build it in the Quote Builder admin, then paste the shortcode into any page or post — or use the RGT Quote Builder block. It works in Elementor, Divi and every builder.
Does it slow down my site?
No. The scripts load only on pages that contain a calculator, and there’s no tracking or external calls.
