I have created an excel worksheet that lists all my bills. I added a Macro
to sort bills by highest interest rate. Now I want to create an amortization
table for each bill. I can do this but don't know what type of formula will
say: For Bill #1, pay this regular monthly bill amount plus an additional
$100 and when Bill #1 is paid-off, apply these payments to Bill #2 - and so
on.

Any suggestions will be appreciated.
