The following interactive plot shows how the loan's principal changes over time as well as how much you've payed. You can use the bottom panel to zoom into a region of interest. You can also hover your mouse on top of a line to see the closest value.

The following interactive table shows how much you pay (and when), the total amount you have payed and the remaining principal (it is only shown for the months when interest compounding is calculated).
