Description
Alovio Calculator is a calculator-first form builder: give visitors an instant, accurate price while you collect the lead. Build a cost calculator, a price estimate or an instant quote for almost any service — cleaning, moving, construction and renovation, solar panels, landscaping, catering, flooring and tiling, print, agencies, salons or equipment rental — in minutes. Start from a ready template, tweak the prices, and paste a shortcode.
Conditional logic is free. Show, hide or require any field based on another field — or even on the running total — with AND/OR rules and operators for equality, ranges (≥, ≤) and presence (is empty / is not empty). 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.

+ − × ÷,if(),min,max,round,ceil,floor,abs— validated live as you type - Conditional logic — free: show / hide / require, AND/OR, equality + range (≥, ≤) + empty/not-empty operators, conditions even on the running total

[alovio_calculator id="…"]shortcode - 6 ready themes, each a distinct design — Classic (studio card), Minimal (editorial), Midnight (dark glass), Soft (rounded pastel), Bold (neo-brutalist), Slate (compact dashboard) — pick one, no CSS needed, plus a custom accent color

- GDPR-friendly: no external requests, no IP storage, personal-data export/erase integration
- Accessible front end: keyboard-friendly controls, screen-reader announced totals
What it deliberately does NOT do
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.
Free vs Pro
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. Learn more.

FAQ
Is conditional logic really free?
Yes. Multi-rule show/hide logic with AND/OR matching is in the free plugin, on every field type.
Does it process payments?
No, by design. Alovio Calculator generates quotes and collects leads. Connect the conversation, close the sale your way.
Will my totals be accurate?
Yes. Calculations use exact fixed-point decimal arithmetic (no floating-point drift), and the same engine runs in the browser preview and on the server — verified against a shared parity test suite on every release. The server independently recomputes every submitted quote.
Is this a free alternative to Cost Calculator Builder?
Yes — and the feature most calculators paywall, conditional logic, is free here. If you are comparing against Cost Calculator Builder, Calculated Fields Form or a similar plugin, Alovio Calculator gives you show/hide rules with AND/OR matching, a decimal-safe formula engine and lead capture in the free version. Start from one of the 11 templates and you will usually have a working calculator in about ten minutes.
Can I migrate from another calculator plugin?
There is no automated importer yet, but the template gallery plus drag-and-drop builder makes rebuilding a typical calculator a 10-minute job. An importer is on the roadmap.
What about GDPR?
Quote entries live in your own database — no external services, no IP addresses stored. The plugin registers with WordPress’s personal-data export and erase tools, and you can delete all plugin data on uninstall.
Does it work with my theme / page builder?
The calculator renders with namespaced, self-contained styles and plain JavaScript, embedded via shortcode or Gutenberg block — so it works in any theme and in any builder that renders shortcodes.
Which PHP versions are supported?
PHP 7.4 and newer, including PHP 8.4.

Changelog
1.1.1
- The 6 themes are now full, distinct designs rather than colour variants: Classic (studio card), Minimal (editorial ledger), Midnight (dark glass), Soft (rounded pastel), Bold (neo-brutalist), Slate (compact dashboard) — each with its own layout, typography and components.
- Fixed the calculator container to honour its width on every theme (no horizontal overflow), and the toggle switch now renders consistently across themes.
1.1.0
- Added 5 new starter templates: construction cost, solar panel quote, landscaping quote, catering quote, and flooring/tiling cost — 11 in total, each demonstrating conditional logic.
- Templates now showcase conditional pricing: optional priced fields appear based on earlier choices and add to the total only when shown.
- Conditional logic engine: new operators “is at least” (≥), “is at most” (≤), “is empty” and “is not empty”.
- Conditions can now be driven by the running total or any formula result (e.g. show a bulk-discount note when the total passes a threshold).
- New “require this field” conditional action — a field stays visible and must be filled before a quote is requested (validated on the server).
- 6 ready themes (Classic, Minimal, Midnight, Soft, Bold, Slate) — choose a look from the builder with no custom CSS.
- New default accent color for new calculators.
- Documentation and readme refinements.
1.0.0
- Initial release: drag-and-drop calculator builder, decimal-safe formula engine (PHP+JS parity), free conditional logic, quote entries with CSV export and privacy tools, 6 templates, block + shortcode.
