If you're looking for more horsepower and a larger list of features, we also have a Deluxe Edition of the RealData Calculator for a very modest fee. This version has 16 modules, including an advanced loan amortization program. It can handle a variety of payment types and frequencies, and gives you the ability to adjust each payment individually if you wish, from a regular payment to interest-only, re-amortized, skipped, or fixed principal.
The Deluxe can also calculate cap rates, discounted cash flows, key financial ratios from a business balance sheet and P & L, and a great deal more.
Download the free version or find out more about the Deluxe by going to realdata.com. Click the "Download" tab at the top.
