LoanBlaster Lite is a straightforward loan program that can compute the payment, principal, or term when all the other factors are entered. Just enter the interest rate and other known factors, include a description and loan date, and click for the result. Terms can be entered in months or years. You can then view and print an amortization schedule and an annual interest total listing. LoanBlaster Lite includes a good help file and tutorial, though the program is certainly simple enough to run without consulting them.
