APRCalc provides a quick and easy way to compare loan options. Enter any three figures--the amount financed, payment term, interest rate, or payment amount--and APRCalc will compute the fourth. APRCalc calculates amortizations for fixed, variable, biweekly, and other types of mortgages, and payment schedules can be weekly, biweekly, monthly, quarterly, semiannually, or annually. Annual and per-payment subtotals can be easily displayed. Professional quality printouts can be created, and registered users can customize the program. Scenarios can be saved in files and even password-protected. A variety of prepayment options let you compare effects on principal, compute the amount necessary to shorten the term to a specified number of payments, and more. You can calculate break-even dates for discount points on mortgage loans to determine how long you'll need to own the house to come out ahead. You can attach notes to any scenario (or any payment) for reference purposes, drag and drop files, and display multiple copies for side-by-side comparison. It supports infinite undo/redo and autosave.
