in what you know PerSense
senses what you don't know, and completes the picture.
screens are organized as column-and-row spreadsheets with
pre-programmed formulas. What is special about PerSense
is that the inverse of
every formula is available in the same template, with a smart algorithm
that notes from context what is missing, and calls on the correct
formula to calculate it.
Leave any cell on any screen blank;
when enough information has been entered to determine that value,
will compute that cell the next time you press Enter or choose Calculate.
For example, you can compute loan payments in
the Amortization screen by filling in loan amount, dates, and interest
rate. But on the same screen, you can also leave the interest
rate blank, and fill in the monthly payment instead. This time it
is the rate that is computed. Or you can fill in both rates and
payments, but leave the duration blank for PerSense
to compute. Or,
filling in all of these, you can ask PerSense
to compute a terminal balloon that will complete the loan.
This intelligent flexibility is the feature that
