Loan calculator

[SMB]

Does anybody know of a web site that might have what I would call a "reverse" loan calculator whereby you input the loan amount, interest rate and payment frequency and the calculator determines the number of payments and the last (usually slightly different) payment amount?

This is for those participants who want to specify a specific dollar amount per pay period that they want to pay on a participant loan.

Thanks - any and all info, comments and/or suggestions welcome!

You can do the calculation in Microsoft Excel by using the NPER financial function.
