Amortizer is a personal finance software featuring a loan calculator. It is a spreadsheet program that calculates loan payments based on loan amount and interest rate that you provide. To start with, you create a new entry by entering a loan name, loan amount, term, payments made and the loan interest. The program does the basic calculations with this information and gives you the balance. The features include reminders for payments that pop up when the due date nears. It even allows for irregular payments so that you can skip any number of payments and yet the program calculates and prepares the loan payment schedule for you.
