Alovio Calculator is a calculator-first form builder: give visitors an instant, accurate price while you collect the lead. Build a moving cost calculator, a cleaning price calculator, a print quote, an agency estimate, salon pricing or a rental cost calculator in minutes — start from a template, tweak the prices, paste a shortcode.
Conditional logic is free. Show or hide any field based on another field — sliders, dropdowns, toggles, quantities — with AND/OR rules. No upgrade wall in front of the feature a quote calculator actually needs.
The math is exact. Every calculation runs on a fixed-point decimal engine, mirrored in PHP and JavaScript and locked together by a shared test suite — so 0.1 + 0.2 is 0.3, totals never drift by a cent, and the price your visitor sees is the price your email says. Works on any host running PHP 7.4 or newer.
<h4>Features (all free)</h4>
<ul>
<li>Drag-and-drop builder with 11 field types: number, slider, dropdown, multiple choice (with images), checkboxes, toggle, quantity, text, heading, HTML, formula</li>
<li>Per-option prices on choice fields; live sticky summary with line items and total</li>
<li>Formula fields with <code>+ − × ÷</code>, <code>if()</code>, <code>min</code>, <code>max</code>, <code>round</code>, <code>ceil</code>, <code>floor</code>, <code>abs</code> — validated live as you type</li>
<li>Conditional logic (show/hide, AND/OR, all operators) — free</li>
<li>Quote requests: name/email/phone/message form, entries stored in your dashboard, email notification, CSV export</li>
<li>6 ready templates: cleaning price, moving cost, print quote, agency estimate, salon pricing, rental cost</li>
<li>Gutenberg block and <code>[alovio_calculator id="…"]</code> shortcode</li>
<li>Currency formatting you control (symbol, position, separators, decimals)</li>
<li>GDPR-friendly: no external requests, no IP storage, personal-data export/erase integration</li>
<li>Accessible front end: keyboard-friendly controls, screen-reader announced totals</li>
</ul>
<h4>What it deliberately does NOT do</h4>
No payment processing — this is a quoting tool, not a checkout. Estimates stay estimates, you stay in control of the sale, and your site avoids a whole class of payment headaches.
<h4>Free vs Pro</h4>
Everything above is free forever — including conditional logic. Alovio Calculator Pro (coming soon) adds a multi-step wizard, PDF quotes, repeater fields, image option styles, webhooks/Zapier and quote analytics. <a href="https://alovio.org/calculator" rel="nofollow ugc">Learn more</a>.
