I have an excel spreadsheet to calculate how much you need to save for retirement and how long your money will last once retired.
The excel sheet works great and intuitive - I need this excel sheet with its calculations and graph to be converted to a webpage that work very similar with the calculations and graphs drawn in the excel sheet.
The webpage should be a single Joomla component or a Joomla site (no hacking the core files!).
It should be one webpage, implemented with Bootstrap 3 or 4, in Joomla, preferably using the Purity III template which is free.
I am looking for a mix of experience and value
