Reviews
what people actually sayCost Calculator Builder is generally well-regarded for its support team and ease of use, but at least one detailed critical review raises serious concerns about bugs and plugin stability that suggest it may not yet be production-ready for complex use cases.

- +Capable of building complex cost calculators×2
- +User-friendly interface×2
Common complaints
- −Geolocation field has critical bugs: fails for non-drivable routes (e.g. cross-continental), inaccurate on second location change, and required validation works inconsistently
- −Multipage calculator becomes unusable after form submission, and fixed-height navigation causes rendering issues
- −Hidden formula fields leave visual traces causing unwanted extra spacing
- −Invoice email rendering has vertical alignment problems and extra spaces from hidden options
- −Default radio button value bug: default option never displays unless an integer value is set, causing confusing behavior
- −Formula ID logic bug: IDs don't auto-update when formula fields are moved, forcing users to redo formulas manually
- −Plugin described as feeling like a beta version overall, with multiple bugs found within just a few days of use
- −At least one user reported a problem arising after a recent update
