A program in which students can change the loan amount, interest rate, period of loan, repayment frequency and if the loan is paid at the start or the end of the payment period. The program shows graphically how the repayments and the total cost of the loan change for differing loan periods. An excellent program if you teach loan amortisation. The program can be downloaded and run as a stand-alone program (recommended as you can run it in full screen mode).
