A free alternative to Cost Calculator Builder.
Cost Calculator Builder is a popular, capable WordPress calculator plugin. If what you want is the same drag-and-drop building — but with conditional logic, decimal-exact math and lead capture in the free version, and no subscription — here is how Alovio Calculator compares.
Why Alovio Calculator
Conditional logic — free
Show, hide or require any field with AND/OR rules, even based on the running total. The feature calculators usually paywall.
Decimal-exact totals
One fixed-point engine mirrored in PHP and JavaScript and locked by a shared test suite — the price the visitor sees is the price your server signs.
Lead capture built in
Quote requests are stored as entries, emailed to you, and exportable to CSV — no add-on required.
No subscription treadmill
The full free plugin stays free; Pro is a separate, optional add-on — not a renewing fee for the basics.
