Interactive components to calculate Square processing fees in real time — including dynamic table components for transparent fee breakdowns across payment types.
Square's fee calculator helps merchants understand exactly what they'll pay before committing to the platform. It's a high-traffic, high-trust page — accuracy and clarity are non-negotiable.
The work involved building a dynamic calculator component and a structured fee table that updates in real time as users adjust inputs.
Built the calculator and table components from design specs, wired to Square's fee logic. Ensured the components slotted cleanly into the existing design system and met accessibility requirements for a page used by merchants across every business size.
