loan amount, interest rate, payment frequency, etc, but will also let me add in
additional payments and change of interest rates; such that it will recalculate
on the fly and show when the loan will be paid off? It should also show which
days payments are due and so on, as a list with dates. (I'll probably have to
write one, though).
Edit: Also, the interest is added to the current amount owing at the end of
every calendar month.
