Build me a simulator -- 2

Hi there, I’m looking to have a simulator built that incorporates a time component (0-100 years), 10 numerical values that can be adjusted as time moves forward which are represented by circles that grow over time as each year ticks by. Each circle’s value is dependent on several factors such as the value added per month/year, percentage deducted at a certain future date, projections based on historical data, current and future tax rates and at least two user defined customizable variables.

GUI is not nearly as important as basic functionality. Once a working model is produced, improving the GUI would be a secondary consideration.
