Generally interest is computed based on an average daily balance for
the month, rather than on the actual amount on one particular day.  A
second approach that that interest it's computed on each daily balance
and the sum is posted at the end of the month.  I've seen both of
these types, there may be others.

Probably present-value, future-value, and a few other "financial
calculations" would be nice to have.
