This example expands on the Monthly Payment Calculator example<\/a> we posted earlier.<\/p>\n

As well as calculating the monthly payment for a loan, it then goes on to use that to calculate the balance of the loan after each payment. This is often referred to as an amortisation schedule.<\/p>\n

The displayMonthlyBalance() method handles generating the schedule using a for loop. Each iteration of the loop corresponds to one monthly payment, with the months interest calculated and add to the balance, then the monthly payment deducted from the payment.<\/p>\n

\r\nfor (int i=0; i<termInMonths; i++) {\r\n\t\t\t\r\n    \/\/ Add interest to the balance\r\n\t\t\t\t\t\t\r\n    \/\/ Subtract the monthly payment\r\n\t\t\t\t\t\t\r\n    \/\/ Display running balance\r\n               \r\n}\r\n\t\r\n<\/pre>\n
\nFull source code to our Mortgage Calculator example is available to our members. We include two variations, both with complete source code. The first accepts user input to get the details on the mortgage to calculate amortisation table for. The second reads the mortgage details from a file use the Scanner class<\/a>. Download the complete source code<\/a>, and be sure to let us know if you have any questions.
