Project overview
2410 transformed a static Excel-based financial model into an interactive online calculator.
The tool allows users to input and adjust values such as initial capital, withdrawal percentage, and inflation rate via sliders. The changes reflect instantly in visual charts showing capital depletion and inflation-adjusted income.
The project required replicating Excel’s formulas using JavaScript and ensuring dynamic chart updates.
Extremely fast response, delivered ahead of time. Even responding on feedback after initial delivery was nearly instant.
Was great working with 2410, will be using them again. Communication, delivery speed, and technical execution were top-notch.
