amortization schedule calc without interest rate known
 

looking for a free online (or template) that can generate a full amortization
schedule when one variable (usually the interest rate) is unknown. I've
tried bankrate.com but its version can't handle a date prior to current date.
First template I downloaded from microsoft.com didn't have the ability to do
the calculation and print out a schedule. Have numerous clients with loans
that I need to have this schedule in order to apply principal/interest on
monthly payments.

I think you are trying to say that you know the payment
amount, original (or current) balance of the loan, and the
original (or remaining) term of the loan.

Try taking an Excel template and changing the cells for
interest and payment. Usually the payment cell uses the
PMT(...) function. Replace that with a constant. Usually
the interest cell contains a constant. Replace that with
the following formula:

=12*RATE(months, payment, -balance)

Caveat: If you only have the current balance and remaining
term of the loan in months, you might encounter further
problems if the remaining term is not a multiple of years.
Ideally, work with the original balance and term.
Alternatively, find a template that expresses the term of
the loan in months, not years.
