S_Loan

If I were to tell someone that it is possible to reach
retirement age and still have unpaid student loans, you would think
I was in a joke-making mood. Well no, it is possible ( although the
complete telling is well beyond the scope of this blog, and human decency
 generally). And - given that tax time is here -  there is about to be an app for it.

Calculations are simple, really. All derive form the simple notion of
compound interest calculations. If I invest 120$ at 5% for ten years,
and leave the money in, at the end of the period I will have
120 x 1.05^10 dollars, which is 195.47$.

The problem, for the student loan, is that one often has incomplete info
like a slip that says you paid so much interest last year or whatever and the
underlying situation is unclear. This app should resolve all situations. Here comes:



I am setting to work in Visual Studio and should have a prototype before too long!

Of concern from a mathematical point of view, passage to base e gives a much more accurate
number for continuous accretion. Our 120$ investment calculated on the basis of ongoing interest
gain ends up being worth 120 * e^(.05 *10), which gives 197.85$. One would go to this formula for calculating a physical phenomenon, like ice melt.

The firdt calculation module could look like this:
