Project overview

The brief

The client wanted to integrate a Compound Interest Calculator into their WordPress website based on a reference application. The calculator needed six editable input fields, accurate financial calculations, results shown in an interactive chart and data table, and the ability to download results in multiple file formats.

The goal was a fast, user-friendly calculator that provides clear financial insights while making it easy for users to save and share their results.

We developed a fully customised Compound Interest Calculator and converted it into a custom WordPress plugin for seamless website integration, replicating the reference application's calculation logic while delivering a modern, responsive experience.

Key features
  • Six editable input fields for personalised calculations.
  • Real-time compound interest calculations with instant results.
  • Interactive charts powered by Highcharts for clear data visualisation.
  • Dynamic data tables synchronised with calculation results.
  • Multiple export options, including Print, PNG, JPEG, SVG, CSV, and XLS.
  • Shortcode support for easy placement anywhere on the website.

The final solution delivers accurate financial calculations, interactive reporting, and flexible export capabilities, giving users a complete and engaging calculator experience.
