Your website is your 24/7 storefront. For many businesses, it still talks at people. Calculators flip that into a two-way interaction: users enter inputs, get a personal result, and feel confident taking the next step.

Zyflora lets you build a working calculator for free from any page you already have. Paste your page URL and relevant text, and Zyflora maps inputs, builds formulas, and outputs a single HTML/CSS/JS block you can paste into WordPress or any site. If you don’t provide prices, Zyflora can prefill sensible industry-range defaults that you can edit. Most builds take under 2 minutes.


What You Can Build (Fast)

  • Cost estimators (bathroom, kitchen, flooring, roofing, HVAC, painting)
  • Quantity calculators (paint needed, soil volume, concrete, tiles)
  • ROI and savings (SaaS ROI, heat pump savings, payback period)
  • Scoring tools (readiness checks, budgeting tiers, package fit)
  • Service quotes (fixed + variable items, add-ons, quality levels)

All outputs are platform-agnostic and run on any site without external libraries.


How It Works in Zyflora

To build a fully functionlal calculator you can do it in only 3 simple steps:

  1. Start a calculator
    • Paste a URL (Zyflora reads headings, labels, and numbers), and past text from the webside with data.
  2. Generate
    • Click Generate and get a code block that you can use on any page.
  3. Publish
    • Paste into a WordPress Custom HTML block (or any CMS/page builder), save-

No plugin. No dependencies. Just one block of code you control. If you want to change prices or text, just go into the code and change. The code is yours forever and you can use it on any of the pages you own.

Example: Bathroom Renovation Calculator (Built in ~2 Minutes)

We built a bathroom price estimator with:

  • Inputs: bathroom size, quality level, and selectable items (shower, heater, faucets, toilet, vanity, tiles).
  • Logic: base price + area rate + item add-ons, quality multiplier, VAT if needed.
  • Output: an instant total and a simple line-item breakdown.

Why Calculators Work (Marketing Value)

  • Instant value: Users see a personalized estimate now, not after an email back-and-forth.
  • Better leads: People who complete a calculator are warmer and more informed.
  • Education by doing: Complex topics become simple when the user tries variables themselves.
  • Engagement: Interactive tools increase time on page and reduce bounce.
  • Higher intent follow-ups: Show the result immediately; then offer a detailed PDF report in exchange for an email. You’ve earned the opt-in with value first.

Tip: Pair your calculator with Zyflora’s splash/lead-magnet page (or your own form) to deliver the PDF result and route inquiries.



WordPress: Paste and Go

  1. Add a Custom HTML block.
  2. Paste the full Zyflora code block (HTML, CSS, JS).
  3. Update the page and test inputs.
  4. Optional: wrap with your form or CTA buttons below the result.

No theme hooks, enqueues, or extra plugins required.


Localization

  • Currency: Change currency symbols and number formatting inline.
  • Language: Translate labels, tooltips, and messages in the same block.
  • VAT/Tax: Add region-specific VAT in the formula (total * 1.25, etc.).

We already have working examples localized for multiple countries and languages.


Data & Privacy

  • Calculations run in the browser. No external calls are required for the calculator to work.
  • You control all text, prices, and formulas. Nothing is locked away in a third-party script.
  • For lead capture, connect your existing form provider (or use a Zyflora splash page).
